Abstract:
A field experiment entitled “Response of kharif groundnut to different sources of organic and inorganic nutrients under North Gujarat condition” was conducted at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sandarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during kharif season of 2020-21. The soil of experimental field was loamy sand in texture with low in organic carbon, low in available nitrogen, medium in available phosphorus and available potash having pH of 7.1. The experiment consisting of ten treatment combinations comprising 100% RDF (12.5:25:00 kg/ha) and combinations of 75% and 50% RDF with FYM 5 t/ha, castor cake 0.5 t/ha, Rhizobium + PSB and different combinationa from above were evaluated in randomized block design with four replications. Plant population at 30 DAS and at harvest did not differ significantly due to different combination of organic and inorganic sources of nutrients. Significantly the higher number of pods per plant, no. of nodules per plant at flowering, fresh and dry weight of nodules (g), number of seeds per pod, pod yield per plant (g), dry matter accumulation per plant (g) at harvest, pod yield(kg/ha), haulm yield (kg/ha), shelling percentage (%), gross realization net realization and B: C ratio was recorded under 75% RDF + castor cake 0.5 t/ha + Rhizobium + PSB which was at par with 75% RDF + FYM 5 t/ha + Rhizobium + PSB in all above mentioned observations.
