Strategy
§ Evolving
short duration nutritious fodder varieties to fit in food fodder cropping systems.
§ Forage
varieties tolerant to abiotic stresses (saline, alkaline and drought situation)
for better adoption of forage production technology.
§ Fodder
varieties will high yield and better quality.
§ Forage
based cropping system under irrigated condition-For improving balanced
nutrition inclusion of perennial legumes.
§ Design
of Grassland and pasture management /silvi- horti pastoral systems for

1. Following Fodder production technologies have been developed recommended for cultivation for farmers of Assam.
· Production technologies of major forage crops of the state of Assam has been developed. Among annual forage crops Package of Practices (POP) for Maize Teosinte, Coix, Oat, Lathyrus, Cowpea and Ricebean have been developed. Among perennial grasses POP for Hybrid Napier, Setaria, Guinea, Para and Congosignal grass has been developed.
· Fodder nursery technique for quick multiplication and availability of perennial fodder has been developed.
· Seed production technology for different annual forage crops of the state has been developed.
· Year round forage production system for un interrupted supply of green nutritious fodder .
· Suitable forage based and food - forage cropping system fertilizing non 9. competitive/fallow land.
· Production potentiality of perennial grasses under Silvipastoral system have been
developed.
· Production technology for dual type rice has been developed
· Fertilizer economy through integrated nutrient management in oat , hybrid napier and setaria has been evolved
· Fertilizer management in non-conventional forage crops like Coix and teosinte has been developed.
· Nutrient management in Dual purpose oat
II. Component Agronomic Technologies are also developed some of which are enlisted below
Cultural Management
· Stubble shaving at ground level to old stand of setaria along with intercultural operation at every cut ib productive that other practices
· Planting of setaria from March with the onset of monsoon to the month of May was found to be better that later dates of planting.
Fertility Management
· In Coix KCA-3 recorded the highest GFY and increased application of N resulted in increase in production of GFY.
· In teosinte JHT-04-1 out yielded all the entries tested and increased level on N from 30-90kg N/ha resulted in increasing trend in respect of green forage production.
· In cowpea Bundel lobia-1 recorded the highest yield of green forage with the application of 60kg P2O5/ha.
· In ricebean variety K-I recorded the highest GFY with the application of 60kg P2O5/ha.
Management of acid soil
· Application of lime + recommended dose of P and K +VAM to both rabi and Kharif crop recorded the highest green forage yield in ricebean-oat sequence under upland condition.
Integrated nutrient Management
Integrated nutrient management in rice- oat + lathyrus cropping system was found to be productive. Application of 25% of recommended dose of fertilizer+ 50% N through FYM+ green manure crop recorded the highest rice equivalent yield. Application of both organic and inorganic source of nutrient also improved the soil chemical properties
Cropping System
Research programme of intensive cropping for increased production of forage crops has been carried out and has resulted in the development of following production system.
· Production of Guinea grass, Setaria and Congosignal grasses under shaded condition of tree which is a suitable technology for Homestead Agro forestry system
· Intensive Food-Forage Cropping system suitable in respect of productivity and profitability has been evolved.
· Forage based intercropping cropping systems in relation to acid soil management has also been developed.
· Forage production under rice based cropping systems have been evolve to meet the green forage requirement during lean period
