RESUMEN
Soybean called as golden beans belongs to leguminosae family. It is native of East Asia. It is rich source of protein and also an excellent source of fiber. Balanced fertilization is necessary to increase the productivity of pulses. Organic manures and formulations favor plant growth and regulation and adaptability to the surrounding environments in terms of improvement in yields and quality parameters in addition to enhanced tolerance to biotic and abiotic stresses. Unlike, chemical fertilizer, these organic products are biodegradable, non-toxic, non-polluting and non-hazardous to humans, animal and birds. Thus, integrations of organic manure and formulations with chemical fertilizer seems to be an alternative supply for plant nutrition. Keeping the above points in view the present experiment were conducted during kharif-2020 and kharif-2021 at Research Farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture, VNMKV Parbhani, to study the effect of vermicompost and organic formulations on growth and yield of soybean grown on Vertisol. The experiment was laid in factorial randomized block design with twelve treatments and three replications. Experimental treatments consist of two factors in which one factor consist of vermicompost consist of three levels C1-RDF, C2- Vermicompost eq. to RDN, C3- Vermicompost eq. to RDN + RD of vermicompost @ 5 t ha-1, another factor organic formulations consist of four levels OF0- control, OF1- Panchagavya, OF2- Beejamruth + Jeevamruth, OF3-Beejamruth + Jeevamruth + Panchagavya. The growth parameters like leaf area, no. of pods and chlorophyll a, chlorophyll b and total chlorophyll showed significant increased with the application of RDF as compared to other treatments. Among organic formulations treatments highest value recorded in combined application of Beejamruth + Jeevamruth + Pancahgavya (OF3) as compared to alone application. The significant increase in seed and straw yield was recorded in treatment receiving in treatment combination of RDF (C1) along with combined application of Beejamruth + Jeevamruth + Panchagavya (OF3). The result of the experiment revealed that application of RDF along with combined application of Beejamruth + Jeevamruth + Panchagavya was found beneficial for increase in growth and yield of soybean in Vertisol.
