A field experiment entitled, "Effect of inorganic and bio-fertilizers quality of summer groundnut (Arachis hypogaea L.)" was conducted at PG Research Farm, Agronomy Section, R.C.S.M. College of Agriculture, Kolhapur during summer, 2019. The experiment was laid out in factorial randomized block design (FRBD) with three replications and nine treatment combinations of three inorganic fertilizer levels F1-75% RDF (18.75:37.5:0 kg ha -1 ), F2-100% RDF (25:50:0 kg ha -1 ), F3-125% RDF (31.25:62.5:0 kg ha -1 ) and three bio-fertilizers levels B1-Control, B2-Rhizobium spp. + PSB (Lignite based), B3-Rhizobium spp.+ PSB (Liquid based). The crop was fertilized as per treatments by using urea and single super phosphate was given by placement method. The application of 100% of RDF ha -1 was comparable with 125% RDF ha -1 significantly over 75% RDF ha -1 in respect of recording higher value of quality attributes viz., oil content in kernel, oil yield, protein content in kernel and protein yield. The dual seed inoculation of Rhizobium spp. + PSB (Lignite based)as well as Rhizobium spp. + PSB (Liquid based) in respect of recording higher value of quality attributes viz., oil yield, oil content in kernel, protein content in kernel and protein yield. The quality attributes of groundnut were not influenced by the interaction effect of both the factors. This indicates that the both factors under study viz., inorganic and biofertilizer levels behaved independently in respect of quality of summer groundnut variety.
An present field experiment was carried out to assess the effect of nutrient management on summer green gram (Vigna radiata L.) during summer 2020 at Agronomy Research Farm, RCSM College of Agriculture, Kolhapur (MH), India. The soil of experimental field was sandy clay loam textural class, slightly alkaline in reaction (pH 7.43), having electrical conductivity 0.22 dS m-1, bulk density 1.34 mg m-3 and low organic carbon content (0.39%), low in available nitrogen (238.29 kg ha-1), high in available phosphorus (30.61 kg ha-1) and medium in available potassium (251.29 kg ha-1). The field experiment was laid out in Randomized Block Design (RBD) having eight treatments and three replications.A 30 cm x10cm spacing and Phule Vaibhav variety was used for seed sowing.The result showed that growth attributes at harvest viz., plant height (66.40 cm), numbers of branches plant-1 (8.20), number of functional leaves plant-1 (29.80), leaf area plant-1 (7.39 dm2) and dry matter accumulation plant-1 (31.70 g) were observed maximum with application of 100% RDF + Vermicompost 2.5 t ha-1 along with biofertilizers seed treatment as compared to other treatment. Also grain yield (15.70 q ha-1), stover yield (33.97 q ha-1), biological yield (49.67q ha-1) and quality attribute like proteincontent and protein yield were recorded more with the integrated application of 100% RDF + Vermicompost 2.5 t ha-1 along with biofertilizers seed treatment as compare to other treatments. However, lowest values of growth attributes, yield and protein content were recorded in un manured condition (Control plot).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
