EFFECT OF DIFFERENT WEED MANAGEMENT PRACTICES ON YIELD OF POTATO IN CHATTOGRAM HILL DISTRICTS OF BANGLADESH

To evaluate the effect of different weed management practices on the yield of potato, a field experiment was carried out with potato during 2017-2018 at farmer’s field of the three hill districts of Chattogram, Bangladesh. The results revealed that the maximum weed control efficiency, marketable tuber yield was found in T3 (Hand weeding + Mulching= Two hand weeding was done in 30 DAT and 90 DAT and straw mulching were done in 30 DAT and continued up to harvesting) followed by T4 (Herbicide =Apply paraquat in 30 DAT and 60 DAT @ 851 g a.i. ha-1), T2 (Mulching= Straw mulch were done in 30 DAT and continued upto harvesting), T1 (Hand weeding = Three hand weeding was done in 30 DAT, 60 DAT and 90 DAT), respectively. The minimum was found in T6 unweeded control treatment. So, the findings of the experiment provide us with a great opportunity of using hand weeding and mulching in combination to cope up with the labour crisis and minimize the cost of cultivation in the hill districts of Chattogram, Bangladesh.
