Abstract


A field trial was done to determine the optimum sowing date and nutrientlevels 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-plotdesign and every treatment was replicated thrice. Three sowing dates(the last week of January, the first and second weeks of February) wereperformed in the main plot, and four different nutrient levels (20:40:20 kgNPK ha-1, 25:50:25 kg NPK ha-1, 30:60:30 kg NPK ha-1 and 12.5 tons FYMha-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, andseed yield were noted. Sunn hemp sown during the second week of Februaryalong with 30:60:30 kg NPK ha-1 was noted with higher yield attributes andseed yield of Sunn hemp.
