Abstract
A field experiment was conducted at the Sorghum Agronomy Block of Instructional Dairy Farm, Nagla of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (U. S. Nagar), Uttarakhand, India, during 2015-16 and 2016-17. The treatments consisted of 12 fodder crop rotations (single cut sorghum+cowpea-oat+berseem-single cut sorghum+cowpea (control), sweet sorghum+rice bean-oat+berseem-sweet sorghum+cowpea, sweet sorgum+phillipesara- 6 row barley+berseem-sweet sorgum+cowpea, sweet sorghum+phillipesara- 2 row barley+berseem-sweet sorghum+ cowpea, sweet sorghum+cowpea-rye grass+berseem-sweet sorghum+cowpea, pearl millet+rice beanoat+berseem-sweet sorghum+cowpea, pearl millet+ phillipesara-6 row barley+berseemmaize+cowpea, pearl millet+cowpea-rye grass+berseem-maize+cowpea, maize+rice beanoat+berseem-maize+cowpea, -maize+phillipesara-6 row barley+berseem-maize+cowpea, maize+cowpea-rye grass+berseem-maize+cowpea, hybrid napier-hybrid-napier+berseemhybrid napier) were tested in randomized block design with three replication.
Season wise total yield of intercropping system was highest due to hybrid napier, sweet sorghum+cowpea (kharif), rye grass+berseem (rabi) and in summer sweet sorghum+cowpea.
Kharif season, fodder mixture from maize+cowpea intercropping system contained higher crude protein and digestible dry matter content. Other quality traits, dry matter intake (DMI), cell content, relative feed value (RFV), total digestible nutrients (TDN), net energy (NEl), metabolizable energy (ME) and mineral content was more in fodder mixture of sweet sorghum+cowpea intercropping system.
Total yield of rotation viz., green fodder, dry fodder, crude protein, digestible dry matter, mineral and organic matter, cropping system productivity (q/ha/day), land use efficiency (LUE), heat energy and carbon sequestration was more in hybrid napier-hybrid-napier+berseem-hybrid napier crop sequence followed by sweet sorghum+cowpea-rye grass+berseem-sweet sorghum+cowpea crop rotation Highest biogas production was observed in the substrates of hybrid napier and pearl millet crop compared to other crop substrates.
On the basis of the present investigation it is conclude that hybrid napier based crop rotation or sweet sorghum+cowpea-rye grass+berseem-sweet sorghum+cowpea cropping sequences are best to get higher yield, quality fodder and soil health.
