Soil Suitability
Water and Power Requirement
Marketability (Demand, Prices and Possible Returns)
Adoptability by Farmers (Crop Agronomy and Cultivation Cost)
Processing Opportunities and Post Harvest Value Addition
Adoptability by Farmers (Agronomy and Investment Capability)Adoptability by Farmers (Agronomy and Investment Capability)
Farmers with less awareness and understanding and technically very weak.
Farmers in the project area are financially weak having low income levels
Prevailing Cropping patterns and Cultivation Practices are considered.
Existing cropping pattern not changed drastically.
Fruit and Vegetable Crops are included to improve economic viability
Crops such as Grapes, Banana, Mango, Chikoo etc whose cultivation costs as
well as agronomic inputs are higher, are not considered
Overall Basis : Farmers’ participation in the project and also expose him to high
income crops and encourage him to learn new techniques slowly.
Eco-friendly / Environmental FactorsEco-friendly / Environmental Factors
Soyabean increases soil fertility.Amala is traditionally Ayurvedic medicinal plant.Most of the crops except Cotton require hardly any chemical sprays.Organic Farming is also possible.Fruit crops such as Amla, Custard Apple and Oranges not only ensure the economic returns but also help in increasing green cover and are eco friendly.
Processing Opportunities and Post Harvest Value AdditionOil mills and Solvent Extraction Plants are available in the district and surrounding areas.Cotton Ginning and Pressing Mills are also available in the vicinity. Local know how, raw material and market is available for Oil Seed Crops.Feasibility of farmers association establishing units for processing and value additionContract Farming by Corporation can be organized.
Water Requirement
•Crops needing low volumes of water such as Soyabean, Amla, Custard Apple are considered
•Calculation of Water Requirement based on Crop Evapotranspiration of Various Crops
•Irrigation of 6968 ha of area with 21.09 million m3 of water in a year
•Water Balance Calculations for 6 different cropping patterns were studied
