摘要

A field experiment was conducted during three consecutive summer seasons of 2016-17, 2017–2018 and 2018-2019 in sandy clay loam soil at the Research Farm, Bidhan Chandra Krishi Viswavidyalaya, West Bengal to study the effect of different weed controlmethods in summer groundnut. The experiment comprising six treatments was replicated four times in a randomized block design. The pre-emergence application (PE) of pendimethalin 1.5 kg/ha followed by post-emergence application (PoE) of imazethapyr 75 g/ha was found to be the most effective in controlling weeds, and resulted in higher groundnut growth and yield attributes, higher pod yield (2.76 t/ha) and maximum BCR (2.65) than other treatments in summer groundnut crop grown in sequence with rice.
