Seed Yield and Economics of Prickly Sesban under Spatio- Temporal Variation in Sowing in Coastal Odisha

Field experiment was conducted at Bhubaneswar, Odisha during kharif 2019 to study the response of prickly sesban to spatiotemporal variation in planting. The treatments of the study comprised five dates of planting. First sowing was done with onset of monsoon on June 13 and rest four at weekly intervals. on 20 and 27 June, 4 and 11 July with three row spacings viz. 80, 120 and 160 cm. Planting on 13 June at row spacing of 80 cm recorded the maximum seed yield of 1.271 t/ha while planting on 13 June at row spacing of 120 cm and planting on 20 June at row spacing of 80 and 120 cm recorded statistically similar seed yields. All other combinations of date of planting and row spacing were inferior to the combination of 13 June planting with row spacing of 80 cm. The earliest date of planting at the closest row spacing recorded the maximum net return of Rs 96.17 x10³/ha and return per rupee investment of Rs 2.27.
