Abstract:
A Field experiment was conducted on loamy sand soil during Kharif seasons of 2018, 2019 and 2020 on study “effect of foliar application of organic and inorganic nutrients sources on growth, yield attributes, yield and quality of blackgram (Vigna mungo (L.) Hepper)” at Agricultural Research Station, Anand Agricultural University, Derol, Ta. Kalol, Dist. Panchmahal, (Gujarat). The experiment was laid out in RBD in ten treatments with three replications and lay out plan is given as follow: T₁: Control (No NPK); T₂: RDF Only (20:40:00 kg NPK ha^-1); T₃: 50% RDF fb 2% DAP at flowering stage; T₄: 50% RDF fb 2% urea phosphate at pre- flowering stage; T₅:50% RDF fb 2% urea spray at pod formation stage; T₆: 50% RDF fb 3% panchagavya at flowering stage; T₇: 50% RDF fb3% cow urine at pre- flowering stage; T₈:50% RDF fb 10% vermiwash at pre-flowering and pod formation stage; T₉: 50% RDF fb sea weed extract@3% foliar spray treatment at pre- flowering stage and T₁₀: 50% RDF fb banana pseudo stem @1% spray treatment at pre- flowering stage. Results showed that effect of foliar application of organic and inorganic nutrients sources treatments had significant at plant height, number of branches plant^-1, number of pods plant^-1, number of seeds pod^-1, seed yield, haulm yield, net return and BCR of blackgram. The maximum value of these parameters was recorded in the treatment T₈: 50% RDF fb 10% vermiwash at pre-flowering and pod formation stage followed by treatment T₇: 50% RDF fb 3% cow urine at pre- flowering stage.
