Abstract:
An experiment was conducted during summer-2019 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar having loamy sand soil to study the nutrient management in summer groundnut (Arachis hypogaea L.) under organic farming. The experiment was laid out in randomized block design and replicated four times with ten treatments. Application of 1.0 t/ha castor cake + Rhizobium + PSB being at par with FYM 5 t/ha + castor cake 0.5 t/ha + Rhizobium + PSB recorded significantly higher plant height at 60 DAS (28.9 cm) and at harvest, number of branches per plant, dry matter per plant over rest of the treatments. Further, it also significantly increased pod yield/plant, pod (1687 kg/ha) and haulm yield (2285 kg/ha), shelling percentage but was at par with the treatments FYM 5 t/ha + castor cake 0.5 t/ha + Rhizobium + PSB and FYM 10 t/ha + Rhizobium + PSB. Plant height at 30 DAS and number of kernels/plant didn’t differ significantly Rhizobium + PSB. Maximum net realization and benefit: cost ratio (BCR) were registered with castor cake 1.0 t/ha + Rhizobium + PSB. Higher yield and net realization can be secured with the application of either 1 t/ha castor cake or 5 t/ha FYM + castor cake 0.5 t/ha along with inoculation of Rhizobium + PSB under organic farming.
