Online published on 31 March, 2025. Abstract A field trial was done to determine the optimum sowing date and nutrient levels on yield and yield parameters of Sunn hemp during summer (January - May) 2022 at Eastern Block Farm, Tamil Nadu Agricultural University, Coimbatore. The field trial was laid out with 12 treatments in a split-plot design and every treatment was replicated thrice. Three sowing dates (the last week of January, the first and second weeks of February) were performed in the main plot, and four different nutrient levels (20:40:20 kg NPK ha-1, 25:50:25 kg NPK ha-1, 30:60:30 kg NPK ha-1 and 12.5 tons FYM ha-1) in the subplot. Yield attributes such as the number of pods per plant, Seeds per pod, seed index, pod setting percentile, pod filling percentile, and seed yield were noted. Sunn hemp sown during the second week of February along with 30:60:30 kg NPK ha-1 was noted with higher yield attributes and seed yield of Sunn hemp.
