Abstract:

A long term manurial experiment on chemical fertilizer in rice-wheat cropping system was taken under All India Coordinated Research Project on Farming System Kuthulia Farm Rewa (M.P.) during 1977-78 to 2015-16 to see the changes on soil fertility and productivity of rice-wheat cropping system. The study reveals that application of 120 kg Nitrogen, 80 Kg P2O5/ha and 40 kg K2O/ha maximized the grain yield of rice and wheat without affecting the soil fertility. The grain yield of rice was increased by 32.22% and wheat by 58.18% at 120kg N/ha as compared to lower doses. The response of phosphorus at 80 kg/ha was 18.68 % in rice 29.87 % in wheat. Application of 40 kg K2O/ha gave 5.54% higher grain yield of rice and 9.46% higher grain yield of wheat as compared to no potash application. The grain yield of rice-wheat cropping system was maximized as 120 kg N/ha 80 kg P2O5 /ha and 40 kg k2O/ha. The net profit was 98.97% higher due to application of 120 kg N/ ha, 35.97 % higher at 80 kg P2O5/ha and 12.03 % at 40 kg K2O/ha as compared to control or lower doses of chemical fertilizer. The chemical property of soil after 38 years rice-wheat crop cycle reveals that available nitrogen status in soil was almost same as initial status. Phosphorus status showed 9.28 % reduction as compared to initial status. The maximum reduction 41.6% was observed in available potash as compared to initial status.
