摘要：
A field experiment was conducted to study the production potential and economic feasibility of different forage based crop sequences under Tarai condition of Uttarakhand. Pooled result of five years indicated that sorghum + cowpea - oat + berseem maize + cowpea sequence produced significantly higher green fodder yield (170 t / ha / year) which remained at par with maize mustard - oat maize + cowpea (169 t / ha / year) and Napier bajra hybrid (perennial) + cowpea / berseem (164 t / ha / year). The dry matter (46 t / ha / year) and digestible dry matter yield (25.5 t / ha / year) were significantly higher with maize-mustard-oat-maize+ cowpea followed by sorghum + cowpea - oat + berseem maize + cowpea. Quality wise sorghum + cowpea - oat + berseem maize + cowpea proved superior producing highest crude protein yield (5.2 t/ ha / year). Among year round forage production systems, Napier bajra hybrid (perennial) + cowpea / berseem realized highest net return (Rs. 25174 / ha / year), B:C ratio (2.05) and production efficiency (Rs. 69/day/ha). Stability index was higher in the order with sorghum + cowpea - oat + berseem maize + cowpea and maize mustard - oat maize + cowpea (0.98) < Napier bajra hybrid + cowpea / berseem (0.95) < sorghum berseem maize + cowpea (0.92). It clearly indicated that forage sorghum / NB hybrid (perennial) based sequence was the most suitable year round forage production system as it provided higher biomass of superior quality for livestock and net return under agro climatic situation of Tarai region of Uttarakhand.
