To identify an ideal combination of organic and inorganic nutrient sources for getting maximum yield of kharif sorghum and rabi chickpea sequence a field experiment on Integrated Nutrient Management in sorghum chickpea cropping system was conducted during 2012-2014 at the experimental farm, Annamalai university, Annamalai nagar. The experiment was planned in RBD with the treatments as Nutrient management treatments - 09 (Kharif-Sorghum) T1-100% RDN through inorganic fertilizer, T2-50% RDN through inorganic fertilizer+50% RDN through FYM, T3-75% RDN through inorganic fertilizer+25% RDN through FYM, T4-50% RDN through inorganic fertilizer+50% RDN through vermicompost, T5:75% RDN through inorganic fertilizer+25% RDN through vermicompost, T6-50% RDN through inorganic fertilizer+25% RDN through FYM+25% RDN through vermicompost, T7-75% RDN through inorganic fertilizer+25% RDN through FYM+seed treatment with microbial fertilizers Phosphobacteria+Azospirillum, T8-75% RDN through inorganic fertilizer+25% RDN through vermicompost+seed treatment with microbial fertilizers Phosphobacteria + Azospirillum, T9- 75% RDN through inorganic fertilizer+seed treatment with microbial fertilizers Phosphobacteria +Azospirillum. In rabi chickpea was gown on the same randomization without application of fertilizers. It can be concluded from the three years experiment that the integrated treatments are superior to inorganic treatment. Application of 75% RDN through inorganic fertilizer+25% RDN through FYM + seed treatment with Phosphobacteria + Azospirillum to kharif sorghum and growing rabi chickpea without recommended dose of fertilizer is the superior treatment for getting maximum growth and yield attributes and yield of individual crop as well as of the system.
