CONCEPT OF CROP DIVERSIFICATION A shift of a crop or cropping system to another crop or cropping system. Use of resources in best possible way by changing and modifying the degree, trend and time options of crop/cropping activities. A shift from less profitable and sustainable crop or cropping system to more profitable and sustainable crop/cropping system. 6

NEED OF CROP DIVERSIFICATION Crop diversification has become an important option to attain several objectives Viz. Natural resources sustainability Ecological balance, Output growth, Buffer stocks, Employment generation, Risk coverage : Mono cropping high risk, etc.
7
7
Thus, the necessity for crop diversification arises on account of the need forReducing risks associated with yield, market and prices, Arresting the degradation of natural resources and environment and Attaining the national goals like self-reliance in critical crop products, earning foreign exchange and employment generation. 88
DETERMINANTS OF CROP DIVERSIFICATION Number of factors governs nature and speed of crop diversification. Resource endowments: ● Agro climatic conditions ● Soil ● Labour ● Facility of irrigation Technological factors House hold factors Institutional and infrastructural factors Price factors 9

The important facts highlighting the need of crop diversification in India: For raising farm income. Sustainable production and income. Food and nutrient security. Promotion of export. Employment generation. Poverty alleviation. Judicious use of land and water resources.
10 10
Priorities for crop diversification in India 1) Changing of parameters.
resource
use
efficiency
2) Crop rotation effect. 3) Incorporation of crops and technologies. 4) Research on actual farm environment through farmer participatory mode. 5) Assurance against the risk to farmers under changing weather and sharp fluctuation in prices. 6) National issues like nutritional and food 11 security. 11
The important crop diversification approaches in rainfed areas of India Crop diversification under assured irrigation situations. Crop diversification under water scarce conditions. Crop diversification for nutrient management. 12 12
REQUIRED STEPS FOR DIVERSIFICATION Crop Diversification Delineate area : Scientific data base priorities and target the area. Choice of alternative crops and technology. Priority Input / credit supply for alternative crops. Share the risk of new system. Market support - Rural uplinking.

Functions provided by diversification
Productivity and stability
Increased yield, reduce intra seasonal variation and improved stability through diverse components viz., crop, tree, plant and animal.
High risk and Risk and cost minimization through yield and high cost income from annual and perennial mixtures. Unabated land degradation
Minimization of kinds, effect and extent of land degradation by appropriate land care through alternate land use system.
Inadequate employment
Staggered employment round the year.

Key determining factors: Farmers Angle Profit margin of new system Availability of market for produce Ease of operation / cultivation / storage Risk factor / technology available Other compelling reasons to shift for a new system Incentive, if any.

Over all strategies for crop diversification Diversion of high water requiring crops to less water intensive crops. Diversion of cotton to pulses, oilseeds and maize in light textured and shallow soils. Replacement of low yielding low value coarse cereals to high yielding high value crops like pulses. Inter cropping or mixed cropping be promoted in dry areas. Shift high risk crops with short duration pulses and drought resistant oilseeds 16 16 crops.

CASTOR, A SUBSTITUTE OF PEARL MILLET IN 28 GUJARAT
28
CASTOR IN CROP DIVERSIFICATION SCENARIO It is an important non edible oil seed crop, earns valuable foreign exchange. High yield potential under irrigated conditions (30- 35q/ha). Also higher yield potentials under dry lands. Economically remunerative crop as compare to existing crop sequences. Suitable for crop rotation and maintenance of fertility as castor posses long tap root system. 29 29

RESEARCH ACTIVITIES It is always desirable to change the crops and cropping system in certain years. The choice of crops or cropping system depending upon price, soil fertility and pest build up will be desirable. Synthesize or decide the most suitable system on considering productivity. Choice of suitable variety is very important to fit in the system with high productivity. Under the diversified intensive system of cropping, contingent planning is also important. Therefore, suitable adjustments should to be made as per emerging needs and prospects. 33 33
CONSTRAINTS IN CROP DIVERSIFICATION 1) Over 117 m.ha (63 percent) of the cropped area in the country is completely dependent on rainfall. 2) Sub-optimal and over-use of resources. 3) Inadequate supply of seeds and plants of improved cultivars. 4) Fragmentation of land holding less favoring modernization and mechanization of agriculture. 5) Poor basic infrastructure like rural roads, power, transport, communication etc. 6) Inadequate post-harvest technologies . 7) Very weak agro-based industry. 8) Weak research - extension - farmer linkages. 9) Decreased investments in the agricultural sector over the 34
years.
34
GOVERNMENT POLICIES AND STRATEGIES FOR CROP DIVERSIFICATION
Implementing National Agriculture Insurance Scheme. Operationalzing Technology Mission on Cotton. Provision of Capital Subsidy of 25 percent for Construction / Modernization / Expansion of Cold Storages and Storages for Horticultural Produce. Creation of Watershed Development Fund. Strengthening Agricultural Marketing. Seed Crop Insurance. Seed Bank Scheme. Cooperative Sector Reforms.
35 35
CONCLUSION Crop diversification or crop shift is a new paradigm of sustainable agriculture. Crop diversification is not only a shift from traditional and less remunerative crop (s) to more remunerative crop (s) but it is a demand driven, need based situation specific and national goal seeking continuous and dynamic concept and involves spatial, temporal, value addition and resource complementary approaches. However, crop substitution and addition of more crops in existing cropping system has been the major approach of diversification in India. The nature of crop diversification is has been mainly from low value coarse cereals to high value oilseeds and other food grains. 36 36
FUTURE THRUST: Inclusion of high value crops through horizontal and vertical diversification approach. Need to synthesize high potential cropping systems and evaluate both on station and on farm in farmers participatory approach. The crop varieties short in duration with high potential yield and most suited for the synthesized systems needs to be identified. The location specific approaches and full packages need to be prepared. For arid and semi arid areas the crops and cropping systems for long term sustainability should be preferred.
