dc.description.abstractRice is one of the Most important food crops grown in Gujarat under low land as well as upland conditions. The rapid increase in cost of chemical fertilizers and their shortage in recent years limit their use. The present investigation was undertaken with a view to study the effect of farm yard manure, Azotobacter, fertilizer nitrogen and phosphorus on growth and yield of GR 11 rice either alone or in conjunction with each other. The experiment was conducted in factorial randomised block design with four replications at North cot cattle Farm, Chharodi of Gujarat Agricultural University during kharif seasons of the years 1982 and 1983. Two levels of farm yard manure (0. 25 tonnes/ha) were employed. Azotobacter treatanents involved seedlings with and without Azotobacter and there were three levels of fertilizer NP namely N50P25, N100P50 and N150P75 kg/ha. The results revealed that FYM at the rate of 25tonnes/ha increased significantly the plant height, total tillers/hill, panicles/m2, panicle weight, grain weight per panicle and mature grains per panicle as compared to those with no FYM. Length of panicle and test weight were not significantly influenced by FYM. The application of 25 tonnes FYM/ha yielded 20.52 per cent higher grain end produced significantly (8.7 per cent) higher straw than those from no fYM, The protein content in grain improved with FYM. Application of Azotobacter was not found to be beneficial as it did not produce significantly higher grain and straw as compared to those from control. It also did not make significant contribution in yield attributes. Plant height and total tillers increase with increasing fertiliser NP levels. The length of panicle was significantly affected with varying levels of NP, The weight of panicle, grain weight per panicle, mature grains per panicle and test weight showed increasing trend with increase in nitrogen and phosphours levels. Crop fertilized with N150P75 resulted in maximum grain as well as straw yield. Protein content in grain increased with increase in NP levels. GR 11 rice crop should be fertilized with 25 tonnes FYM/ha + N150P75 for maximum and economical production under conditions similar to sandy loam soils of North Gujarat. Application of Azotobacter was not found to be beneficial. The judicious use of farm yard manure at the rate of 25 tonnes/ha alone or incombination with inorganic fertilizer is recommended to maximise rice yields.en_US
