A field experiment was conducted at Agricultural College and Research Institute, Killikulam during November 2016 – January 2017 to study the effect of foliar nutrition on the alteration of higher yield in black gram (Vigna mungo (L.) Hepper). Blackgram CO6 was used as the test variety. The experiment was laid out in Randomized block design (RBD) with three replications. It consisted of nine treatments in which DAP, Urea, TNAU Pulse Wonder, Borax, Ammonium molybdate, Salicylic acid, Triacontanol and Polyfeed. The results revealed that application of RDF + foliar spray of 1% TNAU Pulse Wonder recorded significantly higher yield attributes viz., number of pods per plant, number of seeds per pod and seed test weight and finally the grain yield of 692 kg ha-1. It was followed by by the application of RDF + foliar spray of 2% DAP. The grain yield increases with these two treatments were 22 % and 19 % over the sole application of RDF (449 kg ha-1).1
