    BLACK PEPPER PRODUCTION GUIDE

    CULTURE AND MANAGEMENT

    Land Preparation

    For backyard planting, select a well-drained area and divide into equalareas of 2 x 2 square meter lots. At each corner of each lot, dig holes 60cm sq about 40 cm deep. Put kawayan post measuring 4 cm in diameterand 2 meters long at the center of the hole. Mix 1 part of Organic Fertilizerwith 1 part of top soil.

    Planting

    Carefully remove the plant from its container and set it in the hole. Fill theextra spaces with the Pure Organic Fertilizer and top soil mixture.Transplant black pepper seedlings at the start of the rainy season.

    IntercroppingShort-lived cash crops can be used as intercrop to control weed, improvesoil fertility levels, and add to profit. Plant snapbeans, ginger, and hot andsweet pepper approximately 1 meter away from the black pepper rows.

    Weed Contro l

    Hand pull the weeds especially when the plant is still small and the weedsare too close to the plant.

    Irr igationWater the seedlings frequently especially during the first two dry seasons tohelp develop the root system. For mature seedlings, water frequently

    especially when flowering or fruiting. Irrigation can be complemented withmulching, good vegetation, or by shallow cultivation.

    Mulch ing

    Place 4 to 6 inch mulching using rice hull or dried grass at a distance of 6inches from the trunk spreading towards the edge of the crown. This willhelp in restricting weed growth, maintaining relatively low temperature, andin keeping the soil moist even during the dry season.

    Fert i l izat ionFertilization can be done at any time regardless of the season. Werecommend re-fertilization every 2 to 3 months using LAS-1 Activated PureOrganic Fertilizer. Make sure that the fertilizer is well distributed on theblack pepper hill.

    Pruning

    Pruning is done when the seedling reaches 2 to 3 feet high. This is done toinduce more branching, remove unwanted branches, and to removecrowded laterals.

    HARVESTING AND HANDLING

    Black pepper seedlings when properly maintained can bear fruit as early as5 to 6 months. The whole spike is ready for picking when the pepper-corn

    in a spike turns cherry-red, when pepper-corn changes in color from darkgreen to yellowish-green, and the cotyledon exhibit a brownish color whenpinched. Harvesting is done during the sunny season. An open basket orsack is tied to the waist of the harvester and is used as the container. Onehand twists the spike while the other hand holds the peduncle.

    DRYING

    Black peppercorn. Black pepper is dried under the sun. Peppercorn isplaced on mat and spike is removed. Peppercorn is then winnowed,

    cleaned and stored in sacks.

    White peppercorn. Ripe berries are removed from spikes, placed in bagsand soaked in running water 1 to 2 weeks in order to soften skin. Skin isremoved manually or by treading on berries with the feet. Wash and dryimmediately

    GINGERGinger (Zingiber Off ic inale) is an herbaceous perennial, the

    rhizome of which is used as spice. At present ginger is cultivated in these

    Islands in 390 ha. of area with a total production of 1224.60 MT. Ginger has

    a distinct flavour and pungency. The productivity of ginger can be

    increased in the coming years which can in turn add in the economy of the

    farmers, if they practice their cultivation scientifically.

    CLIMATE AND SOIL

    Ginger grows well in warm and humid climate. Moderate rainfall

    at sowing time, till the rhizomes sprout, fairly heavy and well distributed

    showers during the growing period and dry weather about one month

    before harvesting are optimum requirements for its successful cultivation.

    Early planting helps in better growth and development of rhizomes and

    higher yields.

    A rich soil with good drainage and aeration is ideal for its cultivation. Itgrows well in sandy loam or clay loam soils. Drainage is absolutely

    necessary for the prevention of disease incidence. Ginger should not be

    grown in the same site year after year.

    PROPAGATION

    Ginger is always propagated by portions of rhizomes known as

    seed rhizomes. Seed rhizomes are cut into small pieces of 2.5 5 cm

    length weighing 20-25 gm each having one or two good buds. The seedrate varies from 1500-1800 kg per ha. The seed Rhizomes are treated

    with Dithane M-45 (3 gm per lit of water) for 30 minutes, shade dried for 3-4

    hours and planted to control fungal diseases. The seed rhizome bits are

    placed in shallow pits prepared with a hand hoe and covered with well

    rotten farm yard manure and a thin layer soil and leveled.

    PLANTING

    The land should be ploughed 4-5 times to bring the soil into fine

    tilth. Beds of 1 m width, 15 cm height and 3 m length or of any convenient

    length are prepared at 40 cm spacing. About 2000 beds of 3 m x 1 m size

    are prepared in 1 ha. land. Being irrigated crop ridges are formed 40 cm

    apart. The optimum spacing is 30 cm x 30 cm under bed system of

    planting. A bed of 3 m x 1 m can accommodate 40 plants.

    MANURING AND FERTILIZATION

    A basal dose of 25-30 tonnes of FYM alongwith inorganic

    fertiliser in the ratio75:50:50 kg/ha. i.e. 160 kg urea, 270 kg rock phosphate

    and, 80 kg murate of potash is recommended for a hectare of land. Whole

    of rock phosphate and half of murate of potash may be applied at the time

    of planting. Half of the urea is applied 40 days after planting and the

    remaining urea and Murate of potash a month after that. Application of

    neem cake (2 tonnes/ha.) as basal dressing helps in reducing the incidence

    of soft rot of ginger and increases the yield.

    WEEDING AND MULCHING

  • 7/27/2019 cultural practices of spices.docx

    5/16

    Mulching enhances germination, increases organic matter,

    conserves soil moisture and prevents washing of soil due to heavy rains.

    Two weedings are generally given to the crop. The first weeding is done

    just before the second mulching and repeated after 15 days depending on

    the intensity of weed growth. The first mulching is done at the time ofplanting with 12.5 tonnes of green leaves per ha. and second after 40 days

    with 5 tonnes of green leaves per ha.

    ROTATION & INTERCROPPING

    The crops most commonly rotated with ginger are tapioca, chilli,

    groundnut and maize. Ginger is also grown with maize as a mixed crop and

    as an inter crop in coconut and arecanut gardens.

    HARVESTING & POST HARVEST MANAGEMENTIt is ready for harvesting in about 8 months, when the leaves

    turn yellow and start drying. The average yield is 15-30 tonnes/ha.If the

    crop is for vegetable ginger, it is harvested from sixth month. Rhizomes are

    washed thoroughly in water 2 or 3 times to remove the soil and dirt and sun

    dried for a day.For dry ginger, the produce is harvested after eight month

    and soaked in water for 6-7 hours. The rhizomes are then rubbed well to

    clean the extraneous matter. After cleaning, the rhizomes are removed

    from water and the outer skin is removed with bamboo splinter having

    pointed ends. Only the outer skin is to be peeled as the essential oil of

    ginger remains near the skin, and dried in the sun for a week. The yield of

    dry ginger is 19-25% of the green ginger.

    PEST & DISEASE MANAGEMENT

    Burrowing nematode can be controlled by applying FYM or

    compost (25 tonnes/ha) or neem cake (2 tonnes/ha) at planting.Shoot borer

    can be controlled by spraying with the solution of malathion 50 EC (2 ml/lit.

  • 7/27/2019 cultural practices of spices.docx

    6/16

    of water) during July-Oct at 2 days intervals (4-5 sprays).For control of

    rhizome scale insect soak the seed rhizome in solution of quinalphos 25

    EC (4 ml/lit of water) prior to storage and sowing.For control of rhizome rot

    treat the seed with aqueous suspension of Dithane M-45 75 WP (3 gm/lit of

    water) for 30 minutes and air dry before planting. Applying neem cake @ 2tonnes/ha is also effective.For control of bacterial wilt provide good

    drainage. After removing infected clumps drench with copper oxychloride

    50 WP (4 gm/lit of water) around the affected clump. For control of leaf spot

    spraying with Dithane M-45 75 WP @ 3 gm/per lit. of water is advisable.

    Garlic ProductionGarlic is a crop that is well suited to a small acreage or aspart of a larger direct marketing operation looking to

    diversify its mix of crops. It is well adapted for production in

    all parts of the United States. Yield and quality will vary withclimate, region, altitude, soil and pH, cultural practices, and

    the variety of garlic.

    Growing Garlic

    The term "biological elasticity" describes garlic's ability to acclimate to these factors

    over time. No one practice is best suited for every situation. You will want to talk

    with local growers who have experience growing garlic and experiment with

    different cultural practices and varieties to discover the best combination for your

    operation.

    Garlic (Allium sativum) is a member of the lily family. Garlic has been cultivated forthousands of years and is widely used for both its culinary and medicinal attributes.

    Although it is not certain when garlic was first discovered, it was probably dispersed

    by nomadic humans several thousand years ago. As early as the 8th century B.C.

    garlic was growing in Babylon and Chinese scholars mentioned garlic as early as

    3000 B.C.

    Garlic consumption has quadrupled in the United States since 1980 and now stands

    at about 2 pounds per capita. Around 32,000-35,000 acres of garlic are planted

    annually in the United States with total production exceeding 500 million pounds.

    U.S. production is concentrated in California, with smaller acreages in Oregon,

    Nevada, Washington, and New York. Only about one-quarter of U.S. garlic

    production is sold in the fresh market; most is dehydrated. The average price of

    garlic has been around $25-$30 per cwt., but wholesale fresh-market prices have

    been consistently 3-4 times higher. The United States also imports considerable

    quantities of garlic, primarily from China, Mexico, Argentina, and Spain.

    MarketingGarlic can be sold by the pound, by the braid or rope, and at farmers markets by

    the individual bulb or by a bundle of freshly dug bulbs. Retail garlic prices vary

    considerably. Supermarkets generally sell garlic at around $2.00 per pound, while

    some organic grocers sell garlic for as high as $4-$5 per pound. Direct market

    prices can go as high as $1.00 or more per bulb for specialty varieties. At the

    wholesale level, garlic is normally traded as 5-, 22-, and 30-pound boxes; 3-pound

    ropes and braids; and cases of 48 2-bulb boxes.

    When entering into commercial production it is very important to know the

    preferences of your customers. Garlic flavors range from very mild (elephant garlic)

    to very strong (Romanian Red). Find out what your customers prefer before

    selecting varieties. Local retailers are another possible market, but you must take

    the time to contact produce managers and provide good-quality garlic when stores

    require it. Sale of your garlic through a roadside stand (either your own or another

  • 7/27/2019 cultural practices of spices.docx

    8/16

    grower's) can provide opportunities to receive higher prices, but this will require

    some additional expenses for advertising, building and maintaining a facility, and

    providing service to your customers. For more information on marketing,

    consultAgricultural Alternatives: Fruit and Vegetable Marketing for Small-Scale and

    Part-Time Growers.

    Types of Garlic

    Garlic may generally be divided into two subspecies: ophioscorodon (hardneck or

    topset garlic) and sativum (softneck or artichoke garlic). Hardneck garlic produces

    elongated flower stalks (technically called scapes) and bulbils at the top of the

    stalk. Softneck garlic does not produce bulbils, except in times of stress.

    Hardneck garlic may be purple, purple striped, or white and is represented byvarieties such as Roja, German Red, Valencia, Continental, and Creole. Creole

    garlic, a late variety covered with a deep purple skin, is the type grown in Mexico,

    South America, and the Imperial Valley of California.

    With some hardneck varieties, seedstalks may often be topped with a cluster of

    small capsules called bulbels (also referred to as bulbils, topsets or, erroneously,

    bulblets). Although bulbels are sometimes used to produce small garlic bulbs, the

    seedstalks should be removed to maximize bulb size. The term bulblet is more

    correctly applied to the small round bulbs embedded in the scales of, or attached to

    the large main bulb of certain cultivars and types.

    Softneck garlic is also referred to as Silverskin, artichoke, or Italian garlic. Softneck

    types are best represented by the varieties California Early and California Late.

    Silverskin garlic may also be differentiated into many-cloved or few-cloved

    varieties, and may also be tan, all white, or purple tinged. Numerous strains exist,

    having been selected over the years by the various companies that produce them

    for dehydration or growers producing them for fresh market. Silverskin garlic

    rarely, if ever, produces seedstalks.

    Elephant garlic (Allium ampeloprasum ) is not true garlic but a type of leek that

    produces very large cloves (often only 3 or 4 per bulb). Several small bulblets may

    also develop. Its flavor is milder than garlic and can be slightly bitter. It also

    produces a large seed stalk that may be cut and sold to florists. The tender, fleshy

  • 7/27/2019 cultural practices of spices.docx

    9/16

    lower portion of the seed stalk is also prized for stir-fried Oriental dishes. Elephant

    garlic is sold mainly through farmers' markets, specialty produce stores, or

    specialty produce sections of supermarkets. More recently, sales to specialty

    processors for medicinal or health food use have increased.

    Site Selection

    Garlic can be grown successfully in any well-drained soil. Fusarium bulb rot and

    other bulb diseases are a major problem for garlic grown on poorly drained soils.

    Soils that are rich in organic matter with a pH of 6.0-6.5 are best. Heavy clay or

    stony soils are difficult to work in and may cause misshapen bulbs. Your local

    climate and soil conditions must be taken into consideration when selecting garlic

    cultivars. You must practice good crop rotations and plant garlic following a heavy

    cover crop such as buckwheat or rye. Cover crops discourage pests, reduce disease

    inoculum, build soil organic matter, and limit weed pressure.

    Planting

    Garlic is planted in the fall and should be grown on raised beds covered with black,

    green IRT (infrared transmitting), or blue plastic mulch with drip irrigation. On

    smaller operations garlic is often "set" or planted by placing each clove by hand into

    raised beds with rows 6-12 inches apart and cloves spaced 4-6 inches apart

    (depending on the size bulb grown). Larger growers use specialized "cups" on their

    transplanters to place cloves at similar spacings as allowed by the machinery. Most

    garlic cultivars are planted 1-1.5 inches deep; Elephant garlic should be planted 2-

    2.5 inches deep.

    Garlic cloves should be set early enough in the fall so that a good root system can

    develop before the ground freezes, but late enough to prevent shoot emergence

    above the soil line. A mulch of 2-4 inches of straw at planting will help preserve

    moisture, discourage frost heaving, and prevent most weeds.

    Irrigation

    Garlic needs a steady supply of moisture to develop market- sized bulbs. The

    application of one inch of water per week during dry periods through mid-June will

    ensure good sizing. Avoid irrigating garlic after this period to encourage maturation

    and to discourage bulb diseases. For more information on crop irrigation,

  • 7/27/2019 cultural practices of spices.docx

    10/16

    consultAgricultural Alternatives: Irrigation for Fruit and Vegetable

    Production andAgricultural Alternatives: Drip Irrigation for Vegetable Production.

    Fertilization

    Garlic requires heavy fertilization; for commercial production, 125 pounds of

    nitrogen, 150 pounds of phosphorus, and 150 pounds of potassium per acre are

    required. Soil tests should be conducted and phosphorus, potassium, and lime

    should be applied and incorporated before planting. Manure may be used instead of

    commercial fertilizers. However, an analysis should be conducted to determine the

    amount of actual nutrients contained in the manure. To reduce fertilizer runoff,

    nitrogen applications should be split. Apply one 75-pound application at planting, a

    25-pound application at 6-inch height, and the remaining 25 pounds around May 1.

    Granular fertilizer can be applied by banding or broadcasting; liquid fertilizers can

    be injected through a drip irrigation system. Apply all topdressings to dry plants at

    midday to reduce the chance of fertilizer burn.

    Cultural Practices

    Retail customers pay premium prices for large garlic bulbs. To meet this demand a

    grower must remove the scape (flower stalk) as soon as it is visible. If the scape is

    allowed to develop it will compete with the bulb for nutrients, resulting in a

    reduction in bulb size and quality. Once removed, scapes should be disposed of off-site to limit them as a source of disease inoculum.

    Weed Control

    Garlic is a weak competitor with other plants and does not thrive in weedy fields.

    Growers must start with a weed-free planting bed and mulch with clean straw after

    planting. There are only a limited number of herbicides currently registered for use

    in garlic. Herbicide recommendations can be found in the most recent issue of

    thePennsylvania Commercial Vegetable Production Guide.

    Insects and Diseases

    Onion thrips are the major insect pest of garlic in the eastern United States and

    cause a bronzing or whitening of the garlic foliage. Adults and larvae overwinter in

    clover, alfalfa, and small grain fields. Specific insect management recommendations

    for garlic can be found in the Pennsylvania Commercial Vegetable Production Guide.

    Several diseases affect garlic including basal rot ( Fusarium ), white rot

    ( Sclerotinia ), and occasionally Botrytis. Long crop rotations and the planting of

    disease-free stock will limit most of these diseases.

    Harvest and Storage

    Garlic is ready to harvest when 40-60 percent of the leaves have yellowed (garlic

    generally has 6 leaves). Garlic maturation is a function of day length. Most varieties

    are ready by mid-July (with some minor differences between varieties). Early

    harvests reduce storage quality, while bulbs that are harvested too late will start to

    split open. Split bulbs have no commercial value and can only be utilized as

    planting stock. Be sure to discard any planting stock that has blemishes or obvious

    disease signs.

    Because garlic is ready to eat after harvest, curing is only important if you intend to

    store it. For this reason, many growers who market garlic directly to retail

    customers do not cure it after harvest. If long-term storage is desired, freshly

    harvested garlic can be cured by placing it on racks with good airflow. The racks

    should be placed in a location out of direct sunlight and the weather for

    approximately three weeks or until the outer two leaves are completely dry. Many

    smaller growers spread their bulbs on the wooden floor of a barn to cure. Once

    cured, trim the tops and roots and clean the remaining soil from the bulb. The

    cured bulbs should be placed in clean cardboard boxes or burlap bags and stored at

    32-35F and 65-75 percent relative humidity

    Onion Production Planting Through Harvest

    Crop Selection

    There are many factors to be considered in selecting a crop for production. A farmers previous

    experience producing a crop, or the availability of a contract for the purchase of a crop are certainly

    http://agri.and.nic.in/farmpractices.htm
  • 7/27/2019 cultural practices of spices.docx

    12/16

    factors in the de-cision. However, there are two factors which always must be considered. Market

    demand for the period when you could reasonably expect to be able to deliver the product to the

    market using historical data to provide information of the normal volume and price during that period.

    The soil type, climate/micro climate, equipment, irri-gation capacity and experience to be able to have

    a reasonable expectation that an acceptable quality product can be delivered to the market during theidentified period at a unit cost, which allows the farmer to make a profit at the lower end of the

    accumulated range of historical price data. If a farmer can satisfactorily answer the questions raised in

    these two points, he has probably identified a sustainable crop market opportunity.

    Onion Production USAID-Inma 2 Crop Rotation Crop rotation should be a basic part of any sustainable

    cropping plan. It is an effective, low cost and widely used cultural practice to prevent or reduce the

    buildup of populations of soil-borne plant pathogens, weeds and insect pests. An effective rotation

    sequence includes crops from different families that are poor or non hosts of the pathogen(s) and pests

    of concern. In general, the longer the rotation, the better the results. A 3- to 5-year rotation is generally

    recommended. However, from a practical standpoint the number of years and crops to include in a crop

    rotation will depend upon the availability of land, the markets, the selection of commercially viable,

    alternate crops suited to grow in the area, the pathogen(s), and the purpose of the rotation (pathogen

    prevention versus pathogen reduction).

    Crop rotation along with the judicious use of appropriate herbicides is also important in controlling the

    buildup of different weed species. Onions are photoperiod sensitive, which means that varieties initiate

    bulb formation based on day length. Onions are classified as short day, intermediate day or long day

    varieties, depending upon the day length which will trigger bulb formation. Varieties listed as short-day

    onions form bulbs when the day length is between 10 and 12 hours. Intermediate-day varieties form

    bulbs at 12 to 14 hour days. Long-day onions, on the other hand, begin to form bulbs when the day

    length is between 14 and 16 hours. Short day onions planted in spring in southern Iraq would start

    forming bulbs before achieving sufficient plant growth to support sizing the bulb. This would result in

    very small onions. Day length varies greatly as the distance from the equator increases. Green onions

    are long day onions grown in an area where the day length will never be long enough to trigger bulb

    formation. Most of Iraq, with the possible exception of the most northern areas of the Kurdistan region,

    is most suitable for growing short day onions. The optimum time for planting short day onions in Iraq is

    September and October, with another window of opportunity to transplant pencil-sized short-day onion

    shoots in January and February.

    It is possible to plant intermediate day onions in the Kurdistan region in the spring, but growers would o

    been leveled and is suitable for furrow irrigation. However, sprinkler and drip irrigation are much

    referred systems for the production of onions.

    Steps in land preparation:

    Land should be plowed or ripped as deep as possi-ble.

    Prepare a good seed bed, breaking up all clods with a disc and smoothing with a harrow or roller.

    If the onions are being planted behind a crop, which leaves a large amount of organic residue, the

    residue should be worked into the soil.

    Pre-irrigate the field. This will initiate the process of breaking down the residue and germinating weed

    seeds, which are present. Excessive dry matter in the soil will create problems with precision planting

    of the onion seed.

    Garlic Production Guide

    GARLIC (Allium sativum L.), otherwise known as bawang, is one of the more popular

    cultivated Alliums. It is mainly used as a condiment for flavouring meat, fish and salads,

    in fresh and dehydrated forms. It is also known to lower blood sugar and cholesterol

    levels. Its many other health-promoting attributes have resulted in medicinal pills, drinks

    and powders based on garlic extracts.

    Production and Trade

    Garlic is grown in about 5,700 ha mainly in Ilocos Region. In 1997, an average

    production of 15,760t was reported. In 1996, 267.7t valued at P5.35 M were exported to

    the Netherlands and Singapore while 3,990 t of fresh and processed garlic valued at P68

    M were imported.

    Climatic and Soil Requirements

  • 7/27/2019 cultural practices of spices.docx

    14/16

    Garlic grows best in areas with comparatively mild climate. It requires cooler weather during the early

    stages of growth and dry atmosphere with moderately high temperature for maturation. It can be

    grown from sea level to over 1,000 feet above sea level. Areas with Type 1 climate that is dry from

    November to April is best for commercial production of garlic.Garlic can be grown in several types of

    soil. It grows best in sandy loam and silty loam to clay loam with pH of 5.6-6.8. The soil should be fertile,

    rich in organic matter, well-drained and maintains good soil moisture supply during the growing period.

    Land Preparation

    A 1-ha production area requires 1,000 kg garlic seed pieces.With thorough tillage, the land is prepared

    4-6 weeks before planting. The field is plowed 2-4 times at 7 days interval to improve soil texture. The

    use of tractor driven implement requires 1-2 plowing and harrowing operations while an animal-drawn

    harrow needs 4 passings. Apply animal manure at 10-15t/ha prior to bed preparation. Mulch with 3-5cm layer of rice straw after planting to conserve moisture and control weeds. This method of land

    preparation is appropriate for upland areas .Zero tillage is usually practiced in lowland rice fields. Cut

    straw and weeds close to the ground after rice is harvested. Allow soil to dry until desired moisture level

    is attained. Construct canals around the paddies to make sure that no standing water will stay in the

    paddy after irrigation or heavy rain.FertilizationIn the absence of soil analysis, a 1-ha production area

    requires 7 bags of complete fertilizer (14-14-14), 2 bags of urea (46-0-0), 2 bags of superphosphate (0-

    18-0) and a bag of muriate of potash (0-0-60). Apply all 0-18-0 and 14-14-14 as basal fertilizer prior to

    planting. Apply a combination of 46-0-0 and 0-0-60 at 30,50 and 70 days after planting.

    Irrigation

    Irrigate lightly but frequently with 25 cm of water per week to provide continuous and uniform moisture

    supply throughout the growing season. Regulate watering at the onset of bulb formation to ensure

    proper ripening. Stop irrigation when tops begin to fold over, otherwise, it will result in watery bulbs,

    increased rotting and reduced keeping quality.2

    Pest and Disease Management

    Purple blotch (Alternaria porri) and Cescospora leaf spot (Cercospora duddiae). Select healthy planting

    materials. Control humidity within the field with lower panting density and proper irrigation. Spray with

    compost tea (Compost tea is prepared by fermenting rice compost for 10-14 days. The effluent issprayed to control foliar diseases). Remove infected leaves.Black mold (Aspergillus niger), basal rot

    (Fusarium oxysporum) and bacterial soft rot (Erwinia carotovora). Harvest only mature bulbs. Cure

    harvested bulbs properly. Maintain good air circulation during curing. Packing and storage.Thrips (Thrips

    tabaci), army worm (Spodoptera exigua) and cutworm (Argotis spp.). Use overhead irrigation, spray with

    water and soap solution at high pressure. Remove thrips-infested leaves. Spray with hot pepper extract
