Abstract:
A field experiment was carried out in the kharif season of 2020 and 2021 at Hiyanglam Mayai Leikai in the Kakching district of Manipur. The experiment was laid out in a factorial randomized block design (FRBD) and replicated three times. The treatments comprised four levels of foliar application of nano NPK (19:19:19) and three levels of organic nitrogen through vermicompost. The pooled data showed that the highest plant growth characteristics were seen among the foliar treatments of nano NPK at 1.5%, including plant height, the number of tillers/m2, the leaf area index at all stages of direct seeded rice growth and the highest grain yield of 6240 kg/ha and straw yield of 8227 kg/ha. Among the organic nitrogen sources, the application of 100% RDN using vermicompost yielded the highest grain production (5458 kg/ha), which was followed by applications of 75% RDN and 50% RDN. The direct seeded rice's growth characteristics and yield were significantly impacted by the interactions between the various foliar applied nano NPK and organic nitrogen.
