Abstract
The present study was undertaken to assessment of organic and inorganic source of nutrients on growth parameters and productivity of black gram (Vigna mungo L.) cultivar “PU-31”. An investigation was taken up during kharif season of 2019-20 at the Instructional Farm, Rajasthan College of Agriculture, Udaipur. The experiment was laid down in randomized block design (RBD) with three replications. The treatments comprised of four levels of organic source i.e. Control, (PEC1 ) Phospho-enriched compost@2t/ha+Foliar spray@10% vermiwash, (PEC2 ) Phospho-enriched compost@4t/ha+Foliar spray@10%vermiwash, (PEC3 ) Phospho-enriched compost@6t/ha+Foliar spray@10% vermiwash and four level of inorganic source i.e. control, (F1 ) RDF, (F2 ) RDF + foliar spray@ 1% salicylic acid, (F3 ) RDF + foliar spray@ 1% salicylic acid + foliar spray of Zn 0.5%. The results revealed that all plant growth parameters, seed, straw and biological yield of black gram were found highest with the combined application of Phospho-enriched compost @ 6t/ha + Foliar spray @ 10% vermiwash and RDF + foliar spray @ 1% salicylic acid + foliar spray of Zn 0.5% which was statically at par with Phospho-enriched compost @ 4t/ha + Foliar spray @ 10% vermiwash and RDF + foliar spray @ 1% salicylic acid + foliar spray of Zn 0.5% during both the years and in pooled analysis.
