CROP RANKING, COMBINATION AND
DIVERSIFICATION
5.1 INTRODUCTION
Last two chapters reveal the general and agricultural land use of the
study region. Present chapter deals with the finding of crop regions by using
crop ranking, crop combination and crop diversification method for Raigarh
district. The cultivation of different crops in the region shows the strength and
weakness of the study region. Study of particular crop in the region gives a
clear cut idea about the region. The relative strength of the real extent of crop
can be studied by crop combination and crop diversification method.
Secondary data at tahsil level is used for computing crop ranking. The data for
this has obtained from Tahsil revenue office record, Socio-economic Review
and Stastical Abstracts and Census Handbook of Raigarh district for the year
2000-2001. The eight crops, namely Rice, wari, nachni, pulses, spices, fruits
and vegetables, oil seeds and fodder crops are considered for crop ranking in
the region. The cultivation of these crops in the region is the direct impact of
climate, soil, physiography, drainage and irrigation. Rice, fodder crops and
fruits and vegetables are the dominant crops in the region

5.2 CROP RANKING
5.2.1 First Ranking Crops
Table 5.2 shows the first ranking crops in the Raigarh district. Two
crops have been identified as first ranking crops. The distribution of these first
ranking crops is shown in Fig. 5.1. Rice ranked first in thirteen tahsils and
fodder crop ranked first in two tahsil of the district. It covers 131380 hectares
area and occupied 56.32 per cent total cropped area of the region. In Uran,
Panvel, Karjat, Khalapur, Pen, Alibaug, Roha, Sudhagad, Mangaon, Tala,
Shrivardhan, Mhasla and Mahad tahsils, rice has observed as a first ranking
crop. Due to heavy rainfall hot and moist climate and black to laterite soil, rice
is well grown in kharip season in almost all tahsils and rabbi season in some
tahsils of the study region. Fodder crops are another crop shows first rank in
two tahsils namely Murud and Poladpur tahsil. It occupies 9975 hectares area
which is 4.28 per cent of the total cropped area of the region. Poladpur lies in
ghat region and Murud tahsil has uplifted topography caused for the cultivation
of fodder crops instead of rice cultivation. Animal raring activity is high in
these tahsils thus fodder crops are taken in this tahsils. Total 141355 hectares
area (60.60 per cent) was covered under first ranking crop out of total cropped
area of the district.

5.2.2 Second Ranking Crops
Total five crops are observed at second rank in the study region,
namely fodder crops, pulses, nachni, Rice and fruits and vegetables. Table 5.3
and Fig. 5.2 display the distribution of second ranking crops in the Raigarh
district. Among these, fodder crops are cultivated in seven tahsils as second
ranking crop. The distribution of fodder crop is mainly towards the
mountainous area and it covers 23407 hectares area. Uran, Panvel, Khalapur,
Pen, Alibaug, Tala and Mahad tahsils ranked second in fodder crops. Fruits and
vegetables are identified as second ranking crop in four tahsils namely Roha,
Sudhagad, Shrivardhan and Mhasla occupying 9604 hectares area cultivated on
a large scale in the coastal area. Mango, cashew, chikku, ratambi, water melon
and coconut are the major fruit crops grown in these tahsils. Rice, nachni and
pulses are observed as a second crop in these tahsils. All these tahsils are
located in the ghat region of the district. Total 40142 hectares area has covered
under second ranking crop and it occupied 17.17 per cent area of the total
cropped area.

5.3 CROP COMBINATION REGIONS
The study of crop combination region constitutes an important aspect of
agricultural geography as it provides a good basic for agricultural
regionalization. The crops are generally grown in combination and it is rarely
observed that a particular crop occupies a position of total isolation than other
crops in a given area at a given time. (Weaver, 1954) The study of crop
Chapter V – Crop Ranking, Combination and Diversification
167
combination of any region gained importance in geographical study. It gives us
the relative position of crop on regional scale for a comprehensive and better
understanding of agricultural mosaic of an agro climatic region. Crop
combination study in geography is fruitful in many ways. It provides an
adequate understanding of an individual crop and crop-combination region are
essential for construction of more complex structure of the stunning agriculture
region. .
Tahsil wise crop combinations are studied by maximum positive
deviation method of Rafiullah and it is analyzed with the help of map.
Rafiullah (1956), based on Weaver’s method, developed a new deviation
method in his work ‘A New Approach to the Functional Classification of
Towns’ (Hussein, M. 2002). The technique devised by Rafiullah may be
expressed as follows:
∑d2p - ∑ d
2n
d = N
2
Where,
d = is the deviation between actual crop percentage and
the appropriate crop percentage in theoretical distribution.
p = is the positive difference.
n = is the negative difference.
N = is the No. of the crops in the crop combination.
Tahsil is selected as a basic unit of investigation. Year 1990-91 and
2000-01 is selected for the delineation of crop combination. In the present
study eleven crops are selected for delineation of crop combination.
5.3.1 ANALYSIS OF SPATIO-TEMPORAL PATTERN OF CROP
COMBINATION (1990 - 91 and 2000 -01)
As per maximum positive deviation method of Rafiullah only two crops
combination are identified out of 11 crops in both period i.e. 1990-91 and
2000-01. In the year 1990-91 out of fifteen tahsils, six tahsils comes under the
Chapter V – Crop Ranking, Combination and Diversification
168
category of monoculture and the remaining nine tahsils are in two crops
combination (Table 5.10 and Fig. 5.9). During 2000-01 five tahsils are comes
under the category of monoculture and remaining ten tahsils are in two crops
combination (Table 5.11 and Fig. 5.10). The crops in two crop combination are
increased during 2000-01.
5.3 2. Monoculture
i. Rice
Rice as a monoculture was observed in Raigarh district for both periods.
In 1990-91, Uran, Panvel, Karjat, Khalapur, Pen and Alibaug tahsils come
under the category of monoculture and they covered the area of 93.2 per cent,
88.72 per cent, 82.23 per cent, 80.15 per cent, 83.76 per cent and 83.55 per cent
of the total net sown area respectively. In 2000-01, Pen, Murud, Shrivardhan,
Mhasla and Poladpur tahsils having monoculture and they covered an area of
77.94 per cent, 32.57 per cent, 33.48 per cent, 25.93 per cent and 33.94 per
cent of the total net sown area respectively
Five tahsils namely Uran, Panvel, Karjat, Khalapur and Alibaug are
shifted from monoculture to two crop combination in year 2000-01 and Murud,
Shrivardhan, Mhasla and Poladpur tahsils are shifted from two crop
Combination in to monoculture in the Year 2000-01. The above tahsils were
receiving high rainfall intensity. The soil is also suitable for rice cultivation;
hence rice is the monoculture in these tahsil.
5.3.3 Two Crop Combinations
During 1990-91 nine tahsils have two crops combination but, during
2000-01 ten tahsils have two crop combinations. Rice is a main common first
ranking crop combined with fodder crops, nachni in 1990-91 and fodder crops,
nachni, pulses and fruits and vegetables in 2000-01.
i. Rice - Fodder crops
The tahsils Sudhagad, Murud and Shrivardhan have two crops
combination in 1990-91, rice and fodder crops are two major dominant crops
among these tahsils. During 2000-01 Uran, Panvel, Khalapur, Alibaug, Roha
Chapter V – Crop Ranking, Combination and Diversification
169
and Mangaon tahsils have two crops combinations. The farmers in the tahsil
changed the crops from monoculture to two crops combination during study
period.
Raigarh district is located at the foothill of Western Ghat covers large
hilly area having large number of domestic animals thus fodder crops are taken
largely in these tahsils.

ii. Rice - Nachni
The rice and nachni are two major crops grown in Roha, Mangaon,
Mhasla, Mahad and Poladpur tahsils during 1990-91. Mangaon is the only
tahsils having rice and nachni as major crops during 2000-01. The area under
rice and nachni are 69.77 per cent and 12.67 per cent of the total net sown area
in Mangaon tahsil respectively. Rice and nachni are the two major food grains
in the study region.
Chapter V – Crop Ranking, Combination and Diversification
173
iii. Rice- Pulses
These two crops are not observed in crops combination during 1990-91.
Rice and pulses are two major crops grown in Karjat and Roha tahsils during
2000-01in rabbi season covering the area 69.30 per cent and 7.46 per cent
respectively. Tur, udid, gram, mung and wal the major pulses growing with
Rice in these tahsils.
iv. Rice- Fruits
Rice and fruits are observed in combination in only Sudhagad. Rice and
fruits are the major two crops in Sudhagad tahsil during 2000-01. Rice is the
first ranking crop and fruits are the second ranking crop and they covered 51.51
per cent and 21.35 per cent area of the total net sown area of tahsils
respectively. The horticulture is well developed in Sudhagad tahsil of Raigarh
district. These two crops are not found in combination during 1990-91 in any
tahsil.
The combination analysis reveals that the rainfall, nature of surface and
soil impacts on the farmer’s decision to grow few crops depending upon local
demand and the prices in the market. Rice is the major crop grown in all tahsils
in the region and other crops are grown in combination are mainly the result of
nature of surface and soil. The crop combination is increased in the period of
ten years. The changing prices of the crops in the market can impact much on
the Farmer. Hence it is difficult to come to the conclusion that the present
combination of crops will continue in future and it may change as per time and
place.
5.4 CROP DIVERSIFICATION REGIONS
Diversification means the raising a variety of crops. In Indian conditions
the diversification is a common phenomenon because the farmers try to satisfy
most of family demands from its own land resulted into crop diversification..
The cultivation of crop depends on physical and socio-economic factors. This
Chapter V – Crop Ranking, Combination and Diversification
174
cultivation of crop shows contemporary competition. Crops are diversified in
the field due to erratic nature of rainfall and insufficient irrigation. Farmers
grow many crops in order to sustain the agriculture. The greater number of
crops leads to greater competition, the higher is the magnitude, higher the
diversification. Many geographers and economists have applied diversification
concept in different sense. Various methods are used to measure the
diversification of crops in area. Various geographers have used indices which
help the comparative study easier. Gibbs Martin has applied diversification
concept for computing measurement of diversification of employment in
industry. Bhatia (1965) has computed crop diversification in India to
understand crop combination in region.
The formula, later on has been modified by Jasbir Singh (1976) and Ayyer
(1969). According to Bhatia crop diversification means the land occupying for
variety of crops, which occupy at least on percent to gross cropped area. The
study of crop diversification is essential to understand the competition of crops
in any region. In order to identify the crop diversification, in present study,
Gibb’s Martin’s Index has been applied. The formula is as under:
Index of Diversification = 1 - ∑X
2
(∑X)2
Where X is the percentage of total cropped area occupied by each crop
or hectareage under individual crop. If the total cultivated area in the region is
devoted fully to single crop it showing the specialization and the index value
will be zero (Singh,1984).
5.4.1 ANALYSIS OF SPATIAL PATTERN OF CROP
DIVERSIFICATION (2000-2001)
Table -5.12 and Fig.- 5.11 shows the spatial pattern of crop
diversification for the year 2000-2001 in the region. The maximum crop
diversification is observed in Mhasala tahsil (0.80) in southern coastal side and
the lowest in pen tahsil (0.35) in northern coastal side.

The whole study area is divided into three crop diversification regions-
1. Area of high crop diversification
2. Area of moderate crop diversification
3. Area of low crop diversification.

High diversification is seen in coastal and southern tahsils covering
80453 hectares area (44.44 per cent to gross cropped area) in Raigarh district.
Seven tahsils namely Uran, Mahad, Sudhagad, Shrivardhan, Mhasala, Murud
and Poladpur tahsils comes under this region. The index value ranges from 0.64
to 0.80. This region covers seven tahsils of the district.
Moderate diversification covers 162999 hectares area (51.78 per cent)
of the region. The index value ranges from 0.43 to 0.54. In this category of
moderate diversification are observed in seven tahsils namely, Panvel, Karjat,
Khalapur, Alibaug, Roha, Mangaon and Tala tahsil. This region includes
central and northeastern tahsils of the district.
Pen tahsil covers 15463 hectares (7.77 per cent) of the total area. Being
the coastal tahsil soil is saline thus the diversification is low in the tahsil. The
index value for Uran tahsil is Pen is 0.35.
In short it can be said that this region is a predominantly a rice producing
area. Apart from, rice, nachni, wari, pulses, oilseeds are is of some importance.
