INDIAN AGRICULTURE

In India, crop diversification is taking place at a faster pace since
1990s.
It is viewed as a shift from traditionally grown less remunerative
crops to more remunerative commercial crops.
The diversification of crops in terms of variation in acreage
allocation are taking place due to price and non-price factors like
agro-climatic conditions, labour availability, irrigation facilities,
etc.

The cropping pattern changes, however, are the outcome of the
interactive effect of many factors which can be broadly categorized
into the following five groups:
Resource related factors covering irrigation, rainfall and soil fertility.
Technology related factors covering not only seed, fertilizer, and
water technologies but also those related to marketing, storage and
processing.

Household related factors covering food and fodder self-sufficiency
requirement as well as investment capacity.
Price related factors covering output and input prices as well as trade
policies and other economic policies that affect these prices either
directly or indirectly.
Institutional and infrastructure related factors covering farm size,
research, extension and marketing systems and government regulatory
policies.

KERALA AGRICULTURE
The trend of crop diversification in Kerala started slowly in favour of
non-food crops since mid 1970s.
In Kerala the shift has been from seasonal crop such as Rice to
perennial crops like coconut, rubber and areca nut.
Food crops like rice, tapioca and pulses are less remunerative
compared to the more patronized commercial crops

OBJECTIVES
The present study is conducted with the following specific
objectives of analyzing the spatial and temporal dynamics of
cropping pattern in Kerala Agriculture.
To analyze the growth trends of area, production and
productivity of major crops in Kerala.
The specific objectives of the study are the following

To analyze the extent of crop diversification in Kerala agriculture.
To study the interaction effect of area and yield on production.

REVIEW OF LITERATURE
In a study of Mahesh.R (1999) past three decades the agriculture
sector of Kerala has undergone wide-ranging changes in terms of
ownership of land, cropping pattern, cultivation practices,
productivity, and intensity of cultivation.

Jayakumar and Velayudhan (2002) tried to analyze the cause and
consequence of agricultural stagnation in Kerala.
The study limited to important food crops and cash crops. Secondary
data was used in the study.
Growth indices of various crops were computed from 1960-61 to
1999-2000.
The study revealed a significant decrease in the growth of area under
Rice and Tapioca while for Coconut and Pepper, nominal increase
were noted but the Rubber has showed a four-fold increase.

Omana Cheriyan (2004) examined the changes in the mode of
labour due to shift in the land use pattern and in the analysis of land-
use- pattern- changes noted some important patterns.
The area put to non-agricultural purposes had increased mainly due
to population pressures.
More land was left fallow or used for less labour absorbing crops.
The study was mainly based on secondary data.

Swades Pal and Shyamal Kar (2012) This paper aims to implement
different measures of crop diversification for a uniform data set of
Malda district.
At the same time it focuses on status and changing pattern of crop
diversification in different blocks of Malda district with a comparative
outlook of District and State level status.
Herfindahl index and Simpson index are widely used measures of crop
diversification.
Monopolization in crop diversification is going on which is reflected
through forward and backward shifting crop diversification into a
single class in between 2001 to 2008.

In a study by Kalaiselvi.V (2012) Generally viewed as a shifts from
traditionally grown less remunerative crops to more remunerative
crops.
The crop shift also take place due to governmental policies.
Market infrastructure development and certain other price related
supports also induce crop shift.

Uma H.R et al (2013) analyzed the impact of cropping pattern on
food security in India.
Based on the primary data collected from individual households with
a focus on Hassan District, in Karnataka.
The major finding of this study is that there is a shift in cropping
pattern from food crops to commercial crops, and this has a direct
impact on food security in future.

Punithkumar L M and Indira M (2014) reported Agriculture is
way of life and a tradition for millions in India for centuries.
More than 60% of people depend on agriculture, directly or
indirectly. Agriculture and allied sector accounted 13.9% GDP in
2013.
And shifts in the cropping pattern resulting in the decline
continuously in area under food crops and increase the prices of
food grains and the food security.

In the study, compound growth rates of area, production and yield of the
selected crops for three periods were estimated to study the growth in
area, production and yield of these crops.
Compound growth rates were estimated with the following exponential
model.
CGR (r) = ( b - 1 ) X 100
The ‘F’ test was applied to test the significance of ‘b’.

Hirschman - Herfindahl Index:
It is a measure of concentration. Index was computed by taking the
sum of square of area proportion of each crop in the total cropped
area.
Herfindahl Index = ∑ Pi
‘N’ is the total number of crops and Pi represents acreage proportion
of the i crop in total cropped area
N
i=1

With the increase in diversification, the index would decrease to
zero on complete diversification .
This index takes a value one when there is a complete specialization
and approaches zero as ‘N’ large i.e. diversification is perfect.
Herfindahl Index range from 0 to 1

Decomposition analysis has been used to find out the area effect,
yield effect and interaction effect.
Decomposition is the act of splitting a time series or other system
into its constituent parts.
To analyze what has contributed to increase or decrease in
production taking into consideration the endogenous factors such
as area, yield and its effects on the production of individual crop
decomposition analysis has been used.

Production in the base year is given by
Q = A *Y -------------- (1)
Similarly, production in the n year is given by
Q = A *Y ;
If we denote Δ A & Δ Y are the change in area and yield in the
n period, then we have
Q = (A + Δ A)* (Y +Δ Y) ------------- (2)
= A * Y + A *ΔY+ΔY * Y +ΔΑ ∗ΔY

Subtracting Qo from both sides
Q – Q = A *Y + A *ΔY +ΔA*Y +ΔA*Y–A *Y
ΔQ = A *Δ Y + ΔA* Y + ΔA*Δ Y
The first term on the right hand side can be considered as the yield
effect the second term as area effect, and the third as the interaction
effect.
Thus total change in production can be decomposed into three
effects, viz., yield effect, area effect and the interaction effect due to
changes in area and yield.

Herfindahl Index

With the increase in diversification, the index would decrease.
In first period the diversification of crops is more because the index
is less. Second and third period the diversification of crops is
reduced.
If index is increasing shifts are occur many crops to single crops.
Slightly more diversification in third period when comparing
Liberalization period as well as the Post-Liberalization period.

During the first period (1984-1993), the area effect contributed to
increase in production of Coconut, Pepper and Rubber.
Yield effect contributed more for the increase in production of Ginger,
Rice and Areca nut.
The interaction effect of Rubber, Coconut and Areca nut constitutes
more among all other crops to increase in production of these crops.

Area effect contributed to increase in production of Pepper and
Rubber.
Yield effect contributed more for the increase in production of Rice,
Coconut, Ginger, Turmeric, Rubber and Areca nut.
Production of Pepper is less, but area is increased this could be
either due to the absence of technological improvement or due to an
increase in area under new field.
The positive and high interaction effect of Areca nut (13.85%) shows
both area yield interaction contributes substantially for the increase in
production.

Production is positive in all crops except pepper.
For Tapioca, Rice and turmeric, a very high yield effect compensates
a large decline in the area.
The yield could be sustained but despite that, the area growth
did not take place to meet the consumption needs of the state.

study deals with the spatial and temporal dynamics of cropping
pattern in Kerala Agriculture. .
As a result of such crop shift the food crop production has decreased
drastically.
By the calculation of index of crop diversification the diversities in
the crop pattern was noticed.
The major food crop rice shows a declining tendency of growth rate
in each period.
CONCLUSION

The decline in area is due to the large-scale conversion of area from
Rice to Rubber, Areca nut and also for other non-agricultural
purposes.
Area under tapioca, which is cereal substitute of rice, also followed
the same pattern of decline in the growth rates.
In the case of tapioca the rate of decline is the highest in second
period.
The large scale conversion of Rice land to Areca nut and Rubber.

Decomposition analysis showed that the area effect has been
contributing more for increase in production of commercial crops
and decreasing production of food crops such as Rice and Tapioca.
Wet lands are converted to non-agricultural uses.
Among eight crops studied during the three periods, rubber and
Areca nut are the only crops that showed positive trend in area,
production and productivity.
