Abstract

A field experiment was carried out during kharif 2019 at Research Farm of Agronomy, Birsa Agricultural University, Kanke, Ranchi to assess the effect of foliar application of nutrients and growth promoter (NAA) on yield, yield attributes and economics of Blackgram. The experiment was carried out in RBD (Randomized Block Design) having twelve treatments replicated thrice. Maximum number of nodules per plant (34.78) was recorded in treatment T3 (DAP @ 1% + NAA @40ppm along with RDF). Maximum number of pods per plant (35), number of grains per pod (4.73) and 1000-grain weight (35.39 g) were recorded highest with T3. Maximum grain yield (1331 kg ha-1), higher gross return (` 76,866 ha-1), net return (` 53,919 ha-1) and B:C ratio (2.35) was recorded with application of DAP @ 1% + NAA @ 40ppm along with RDF.

Keywords

Foliar application, DAP, Urdbean, growth promoter (NAA), yield attributes, economics

Conclusion

Based on the results of the above findings, it may be concluded that foliar application of DAP @ 1% + NAA @ 40ppm at 30DAS and 45 DAS along with RDF (25:50:25::N: P2O5:K2O kg ha-1 ) produced higher yield attributing characters like grain yield as well as straw yield with highest net return and benefit cost ratio making it more productive economically viable for the farmers in Jharkhand.
