Abstract

Seed production in jute can be enhanced by adopting suitable agro-techniques. Among the various agro-techniques, plant density is an important yield contributing factor which can be changed to obtain higher yield in jute. Another important factor is topping which is (clipping of apical buds). An experiment was conducted during kharif, 2019 at Agricultural College Farm, Bapatla with three plant densities [1.66 lakh plants ha-1 (D1), 2.2 lakh plants ha-1 (D2) and 83,333 plants ha-1 (D3)] and four topping practices [T1 (No topping), T2 (topping at 30 DAS), T3 (topping at 45 DAS) and T4 (topping at 60 DAS)] in a randomized block design with factorial concept using JRO 524 (Navin) variety of jute in three replications. Results indicated that maximum leaf area index (LAI) and light interception of jute was obtained with 2,22,222 plants ha-1 (D2) and with no topping practice (T1) which was on par with 1,66,666 plants ha-1 (D1) and was significantly superior over other plant density of 83,333
