INTRODUCTION

Page 4: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Nutrient Requirements 17 elements are essentially required by plants First three elements -Carbon, Hydrogen and Oxygen are

obtained from CO2 and H2O and make 95 % of plant biomass Other 14 elements are called mineral nutrients because they are

taken up in mineral (inorganic) forms.

Macro nutrient (6) Primary nutrient : Nitrogen, Phosphorus and potash.

Secondary nutrient : Calcium, Magnesium, Sulphur

Micro nutrient (8) Iron, Copper, Manganese, Zinc, Boron, Molybdenum

and Chlorine , Nickel.

Page 5: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Role of Macronutrients in Crop Development

Secondary Nutrients – Calcium Stimulates microbial activity Reduces respiration Magnesium Key element in chlorophyll production Improves utilization and mobility of phosphorus

Sulphur Integral part of amino acids Pungent odour of onion and garlic is due to the presence of sulphur compound.

Deficiency of Nutrients

Page 7: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Calcium Deficiency

SPIKE LEAF in Banana

BITTER PIT in Apple

• Young leaves are small, and abnormally green.

• Leaves become cup shaped.

• Poor fruit development and appearance.

Page 8: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Magnesium Deficiency

• Intial yellowing of older leaves between leaf veins spreading to younger leaves given characterstics V shape appearance.

• Poor fruit development and production.

Page 9: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Sulphur Deficiency

• The young leaves turn yellow.

• Deficiency symptoms usually appear first on the youngest leaves.

Page 10: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Zinc Deficiency• Interveinal yellowing

on young leaves.• reduced leaf size.

Page 11: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Boron Deficiency• Young leaves of terminal bud

becoming light green at bases, with final breakdown.

• Die-back and cracking of fruits.

Page 12: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Iron Deficiency

• Initial distinctyellow orwhite areasbetweenveins ofyoung leavesleading tospots of deadleaf tissue.

Page 13: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Manganese Deficiency• Interveinal yellowingor mottling of youngleaves.

Page 14: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Copper Deficiency

• Narrow, twistedleaves and pale whiteshoot tips; dieback ofthe terminal growthleaves appear mottled

Page 15: Impact of Secondary and Micronutrients on Fruit and Vegetable Production and Soil Properties

Molybdenum Deficiency

• Interveinal chlorosison older or mid stemleaves; twisted leaves(whiptail); marginalscorching and rollingor cupping of leaves;

4. Vitamin-C content of the fruit was increased in the concentration micronutrientapplication in all the treatment.

5. The application of micronutrient in general and Zn and B particularly will reduce and control the dieback problem in future.

1.The maximum fruit yield was obtained , when 0.4 kg Zn/ha and 0.2 kg Mn/ha was sprayed along with 1.56 kg N/ha and 0.4 kg surfactance/ha in 400 L of water.

2. The spray of zinc sulphate at 0.4% enhances the TSS, total sugars, sugar/acid ratio and reduced the acidity of the fruits,whereas boric acid spray at 0.4% increase the pectin and vitamin-C contents of the fruits.

3. For improving yield and quality of Flame Seedless grapes under calcareous soil condition of Egypt, It is recommended to apply mixture chelated microelement at 200 ppm as soil application in the beginning of opening bud stage and repeated 2 times- one month intervals combined with spraying GA3 and ascorbic acid at 500 ppm as foliar application.
