Determination of Critical Period for Sustainable Weed Management and Yield of Jute (Corchorus olitorius L.) under Sub-Tropical Condition

A field investigation was run to ascertain the critical period of weed control in jute (Corchorus olitorius). The study consisted two distinct sets treatments, with one set weeds being left invade crop for a longer time, specifically, 15, 30, 45 and 60 days after sowing (DAS) up harvest. In other plants remained weed-free progressively periods, i.e., DAS, until reduction fibre yield (FY) recorded as 53.39% when interference permitted from beginning harvest, opposed season-long period. competition (CPWC) calculated 11 68 DAS 19 59 based on results 5% 10% loss, respectively. Under loss condition, although higher (3.36 t ha−1), benefit cost ratio (BCR) lower (1.65), whereas slightly (3.19 ha−1) but BCR (1.73) respect loss. Therefore, fields should be kept free sowing, management strategy undertaken accordingly.
