EFFECT OF APPLICATION OF NANO-NUTRIENTS ON CROP GROWTH AND SEED YIELD IN BLACK GRAM (VIGNA MUNGO)Anna Joy and Vandna ChhabraAbstract Being one of the important pulse crops grown throughout India, Black gram requires several nutrients for optimum growth. The use of chemical fertilizers to add these nutrients has been known to boost production but at a cost of harming the soil, air, water, and living organisms. To address this issue, nano formulations have been proposed as a potential solution. This study aimed to evaluate the effects of applying nano nutrients, N and Zn on the morphological and yield-related characteristics of black gram. The experiment was conducted with Randomized Complete Block Design having 8 treatments and replicated thrice. Among various treatments, the highest germination percentage and seedling vigour were observed in treatment T5 (50% RDN+ Seed priming with nano-Zn+ Foliar spray of nano-urea at 45 DAS), whereas the higher yield parameters viz., test weight, pods, seeds per pod, pods per plant, biological yield and grain yield observed in T8 (Seed priming with nano-Zn+ Foliar spray of nano-urea at 30 DAS+45 DAS). |
