Abstract

In Bangladesh during 2017-2018 was conducted in a farmer's field of the Chattogram hill districts to determine the effectiveness of different weed control strategies for weed control of transplanted chilli. The dry weight of weeds, weed control efficiency, weed index, and yield components like the number of fruits per plant, fruit length, fruit weight, and marketable fruit yield, had been significantly affected by using weed control measures. In the act of weed treatment in chilli fields, hand weeding+mulching also gave the highest weed control efficiency at harvest (89.19% in Khagrachari, 89.82% in Rangamati and 90.02% in Bandarban, respectively), the number of fruits per plant (130.40 in Khagrachari, 126.70 in Rangamati and 135.40 in Bandarban, respectively), fruit length (7.20 cm in Khagrachari, 7.00 cm in Rangamati and 7.10 cm in Bandarban, respectively), fruit weight (2.00g in Khagrachari, 2.10g in Rangamati and 2.20g in Bandarban, respectively) and marketable fruit yield (11.58 t/ha in Khagrachari, 11.64 t/ha in Rangamati and 11.96 t/ha in Bandarban, respectively) are the highest, while the weed index (3.90% in Khagrachari, 4.04% in Rangamati and 2.68% in Bandarban, respectively), is the lowest for hand weeding and mulching treatment compared with other treatments. Along these lines, chilli production in the hill districts of Chattogram was deemed to be the best eco-friendly and effective weed control strategy for hand weeding+mulching treatment.
