Food - fodder cropping systems with NU management in agroforestry systems rainfed conditions

摘要

A field experiment was conducted during monsoon season of 1993-94 to 1995-96 at the Indian Grassland and Fodder Research Institute, Jhansi to study the different food-fodder cropping systems and manorial schedules in different agroforestry systems under rainfed conditions. Significantly higher grain and stover yields of sorghum was obtained in sorghum+pigeonpea/Cenchrus setigerus inter cropping system as compared to sorghum + cowpea intercropping system. Sorghum + cowpea intercropping system produced significantly more green fodder and dry matter yields of fodder crops than sorghum + grass strips. Higher sorghum grain equivalent yield was obtained in sorghum+piogeonpea followed by sorghun+cowpea and sorghum+grass strips. Among the different manurial schedules, combined application of organic and inorganic sources of plant nutrients produced significantly higher grain and stover yield of sorghum, green and dry matter yields of fodder crops and sorghum grain equivalent yield as compared to 100 percent inorganic fertilizers application in different agroforestry systems. The tree survival was 84.3 percent under rainfed condition after a period of 20 months of their establishment. The tree height of 103.4 cm and collar diameter of 1.33 cm were recorded under rainfed conditions. The forage production from the hedge row was 0.8 t dry matter after 8 months of its growth.
