Effect of neem cake and fish amino acid on the growth and yield of blackgram

A field experiment titled “Effect of Neem cake and Fish amino acid on the growth and yield of Blackgram” was conducted during Zaid season of 2023 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute SHUATS, Prayagraj, Uttar Pradesh. The experiment was laid out in Randomized Block Design with nine treatments which are replicated thrice. The treatments combination are T₁ Neemcake 0.5 t/ha + Fish amino acid 0.5%, T₂ Neemcake 0.5 t/ha + Fish amino acid 1%, T₃ Neemcake 0.5 t/ha + Fish aminoacid 1.5%, T₄ Neemcake 1 t/ha + Fish amino acid 0.5%, T₅ Neemcake 1 t/ha + Fish amino acid 1%, T₆ Neemcake 1 t/ha + Fish amino acid 1.5%, T₇ Neemcake 1.5 t/ha + Fish amino acid 0.5% T₈ Neemcake 1.5 t/ha + Fish amino acid 1% and T₉ Neemcake 1.5 t/ha + Fish amino acid 1.5% are used. Results obtained that combined the application of T₉ recorded significantly maximum Plant height (33.17 cm),Plant dry weight (21.8 g/plant), Number of nodules per plant (39.20), Significantly maximum number of pods per plant (15.52), number of seeds per pod (6.30), Seed yield (1.62 t/ha), stover yield (3.92 t/ha).
