Abstract: A field experiment was conducted during two consecutive kharif seasons of 2015 and 2016 at the Instructional Farm of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India with an objective to maximize the seed yield of Corchorus olitorius cv. JRO-8432 (Shakti Tossa) by adjusting dates of sowing and topping. The experiment was conducted in a split plot design with 3 main plot treatments of dates of sowing (D1-19th June, D2-19thJuly,and D3-19th August) along with 4 subplot treatments of topping operation (T1-No topping, T2-Topping at 30 DAS, T3-Topping at 45 DAS, T4-Topping at 60 DAS) and each treatment was replicated thrice. Irrespective of topping operation, the 19th June sown crop was found superior over other sowing dates with the highest seed yield of 240.46 kg ha-1. In topping treatments, topping at 45 DAS was always found superior to other topping dates in both the years when the highest pooled seed yield of 220.74 kg ha-1was recorded. The 19th June sown crop that experienced topping at 45 DAS recorded the highest seed yield in both the years.
