Optimal nitrogen fertilization timing and rate in dry-seeded rice in Northwest India por Mahajan, G., Chauhan, B.S., Gill, M.S.

“…In this study, we investigated yield and dry matter of rice, and N translocation in response to timing and rate of N application. Nitrogen was applied in three splits (as per regional recommendation of transplanted rice) and four splits with or without N application at sowing time (basal dose) at rates of 120, 150, and 180 kg ha−1. …”
