One effective way to increase the yield of black gram is by applying foliar nano urea, which is a balanced dose of nitrogen. Accordingly, from September to December 2022, the Bangladesh Institute of Nuclear Agriculture (BINA) substation experimental field in Rajshahi was the site of this study, which assessed the growth of black gram (Vigna mungo L.) under two different forms of nitrogen. Using a randomized block design, three treatments were applied to the black gram variety Binamash-3: control (no fertilizer) (T1), farmers practice (recommended fertilizer application as basal dose and top dressing during active growth) (T2), and nano urea (5 ml of nano urea (5 % N) in one litre of water and sprayed on crop leaves at its active growth stages) (T3). The effects of various forms of nitrogen (urea) on yield and characteristics that contribute to yield are significant. The highest grain yield, 1625.32 kg/ha, was produced by T3, while the lowest yield, 995.47 kg/ha, was produced by T1. It was evident that sparingly misting Binamash-3 with nano urea as a foliar spray during its rapid growth stages could greatly increase seed yield and potentially aid other legume ctops in increasing their yield as well.
