Effect of Foliar Application of Different Chemicals on Yield and Yield Attributes of Black gram [Vigna mungo (L.) Hepper] under Rainfed Condition

Abstract

A field experiment was performed at the “TCA., research farm of Dholi (Muzaffarpur), which is a unit of the Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar, during the Kharif season of 2021” to investigate the “Effect of foliar application of different chemicals on yield attributes and yield of Black gram [Vigna mungo (L.) Hepper] under rainfed condition”. The design used for making layout of experimental unit was RBD, that was replicated three times, with ten treatments in each replication for a total of 30 plots. The experiment conducted with 10 treatments viz., Absolute Control (T1), Water Spray (T2), ZnSO4 @ 0.5% Spray (T3), NPK (19-19-19) @ 2% Spray (T4), Urea @ 2% Spray (T5), DAP @ 2% Spray (T6), Salicylic acid @ 100 ppm Spray (T7), Potassium Nitrate @ 2% Spray (T8), Boron 0.25 % Spray (T9), Potassium Chloride @ 0.2% Spray(T10). The foliar spray of different treatments applied had a significant impact on the number of pod number plant-1, seed count pod-1 and the length of the pod. However, foliar chemicals had no appreciable impact on the weight of 100 seeds. At pre-flowering and pod-initiation stage, foliar treatment of “NPK (19-19-19) @ 2 % spray (T4)” resulted in significantly greater seed production and stover output. Different chemical administration to the foliage had no significant effect on harvest index.
