Effect of Organic Manures on Productivity of Greengram-wheat Cropping Sequence under Organic Farming

Manures are significant organic source of plant nutrients. Farmer’s awareness is increasing towards organic farming. An experiment was conducted during kharif and Rabi season of the years 2016-17 to 2018-19 (Three years) at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar having loamy sand soil to study the effect of organic manures on productivity of greengram-wheat cropping sequence under organic farming. The experiment was laid out in completely randomized design and replicated eight times with four treatments. On three years pooled results, growing organically wheat after greengram as succeeding crop are recommended to apply 100% recommended nitrogen to greengram and 75% recommended nitrogen to succeeding wheat crop through castor cake for obtaining higher greengram equivalent yield and net return under North Gujarat Agro climatic conditions.
