Influence of Nitrogen and Weed Management on Tossa Jute

Field experiment was conducted at Kalyani (23.5°N latitude, 89°E longitude and 9.75 m AMSL) at Bidhan Chandra Krishi Viswavidyalaya, India to study the effect of different weed management practices, effect of skipping basal nitrogen on the weed crop competition, yield of jute and also their interaction effect on growth and yield of jute. Pooled data showed higher fibre and stick yield from the treatment where nitrogen was applied at 10 DAS without basal nitrogen. Application of quizalofop ethyl at 15 DAS coupled with one hand weeding at 35 DAS although produced lower fibre and stick yield than the tedious method of two hand weeding or weed free condition but produced higher fibre and stick yield than the application of pendimethalin alone or in combination with one hand weeding. All the weed management treatments did not show any harmful effect on the yield of the following crop blackgram. Therefore, skipping of basal nitrogen and application of 50 % N at 10 DAS and remaining part in two equal splits at 20 and 40 DAS along with application of quizalofop ethyl @ 50 g ha-1 at 15 DAS coupled with one hand weeding at 35 DAS proved best among all the treatments used in this experiment.
