Effect of zinc and boron on growth and yield of Blackgram (Vigna mungo L.)

A field experiment was conducted during kharif season of 2023 at Crop Research Farm Department of Agronomy on blackgram. The treatments consisted of 3 levels of zinc (2, 4 and 6 kg/ha) and 3 levels of boron (0.5, 1.5 and 2.5 kg/ha) with N:P:K – 20:60:20 kg/ha (Control). The experiment was laid out in a Randomized Block Design with 10 treatments and replication thrice. Application of zinc at 6 kg/ha with Boron at 2.5 kg/ha (Treatment 9) recorded highest plant dry weight (18.62 g), pods per plant (27.28), test weight (39.50 g), seed yield (1.60 t/ha).
