Abstract
An experiment was conducted during two consecutivekharif and rabi season from the year 2016-17 to 2018-19 for three years on to evaluate different organic sources performance on groundnut and wheat sequence under organic farming at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The soil of experiment was loamy sand. Experiment was carried out in Large plot technique design and with eight replication for four treatments. From three years experiment result revealed that in kharif season, application of 100% nitrogen through castor cake sequring higher pod yield of groundnut and application of 75% nitrogen through castor cake for succeding wheat in rabi season for getting higher seed yield. Application of castor cake in both season sequred higher groundnut equivalent yield. Maximum gross (Rs 150300/ha) and net neturn (Rs 67922/ha) with BCR of 1.82 was obtained under Treatment T3 (100% RDN through castor cake in groundnut and 75% RDN through castor cake in succeeding wheat) under organic farming under North Gujarat Agro climatic conditions.
