Production Potential Of Fodder Oat (Avena Sativa L.) Based Cropping Sequences With Different Sources Of Nitrogen Under Temperate Climatic Conditions Of Kashmir

Abstract

Field experiments were carried out at Cattle Research Station, SKUAST K, Manasbal, India to find optimum nitrogen source for higher fodder  production of good quality in two cropping sequences during 2007-08 and  2008-09. The cropping sequence of oat-maize-turnip recorded higher  fresh fodder production, dry matter accumulation and crude protein productivity as compared to oat-sorghum cropping sequence. The  magnitude of increase with oat-maize-turnip sequence in above respective  parameters was 24.40, 6.64 and 9.32% over oat-sorghum cropping  sequence. Integrated approach (50% N through organic and 50% N  through inorganic source) proved better than the supply of nitrogen  through organic source only. The supply of nitrogen through integrated  approach recorded 22.28, 20.00 and 17.70% superiority in fresh fodder  , dry matter accumulation and protein productivity,  respectively, over the supply of nitrogen through organic source only.  Further, supply of 50% nitrogen through sheep manure and 50%  through urea proved 25.80, 23.45, 22.0, 11.97 and 1.39% superior in fresh  fodder production over the supply of nitrogen through sheep manure or  farm yard manure (FYM) or vermicompost or 50% N as vermicompost +  50% as urea or 50% N as FYM + 50% as urea, respectively.
