Abstract
A field experiment with wheat cv. WH 283 was conducted during the winter season of 1997-98 and 1998-99 on sandy-loam soil of Hisar, Haryana, India. The experiment consisted of 6 organic manure treatments (no organic manure, farmyard manure at 15 tonnes, vermicompost at 10 and 15 tonnes, pressmud at 2.5 and 5 tonnes/ha) and 5 chemical fertilizer treatments (no fertilizer, N at 60 and 120 kg/ha, N at 90 kg/ha+Azotobacter and recommended dose of 120 kg N+60 kg P2O5+60 kg K2/ha). Application of organic manures irrespective of source and rate increased the dry matter accumulation, leaf area index, effective tiller number, grains per ear, grain and straw yields, photosynthesis of wheat significantly over no organic manure during both years. Maximum values of all the attributes were observed with vermicompost at 15 tonnes/ha, which was significantly superior to the rest of the organic manure treatments. Increasing rate of N improved all the parameters of wheat. Maximum values were recorded with the recommended dose of NPK. However, N at 120 and 90 kg/ha+Azotobacter were statistically at par with recommended dose of NPK.
