Abstract
Potato is one of the most important commercial vegetable crops in India and on an average this crop is affected by weeds damage which should be prevented by various control methods. Cultural operations and mulches are non-chemical methods of weed control in sustainable agricultural systems. The aim of present study was to investigate the effect of chemical and non-chemical control methods on weeds and yield of potato crop. Field experiments were conducted during rabi 2016-17 and 2017-18 at Research Farm College of Agriculture, RVSKVV, Gwalior in a randomized block design (RBD) with three replications. The treatments were as follows: 1) white plastic mulch, 2) black plastic mulch, 3) straw mulching after 5 DAP as 5 t/ha, 4) one hand weeding at 20 DAP + straw mulching at 25 DAP, 5) two hand weeding at 20 & 40 DAP, 6) one hand hoeing at 20 DAP, 7) one hand hoeing at 20 DAP + one hand weeding at 40 DAP, 8) Recommended herbicide (metribuzin 500 g/ha), 9) Recommended herbicide (metribuzin 500 g/ha) + one hand weeding at 40 DAP and 10) Weedy check. Based on results, all treatments were affected by weed control methods. At 60 DAP the highest weeds density was counted as 567.83 plants/m2 of weedy check treatment. The two hand weeding at 20 & 40 DAP deceased weed density 86% as compared to weedy check. The hoeing at 20 DAP with one hand weeding at 40 DAP and straw mulching with one hand weeding were also deceased weeds density around 75% comparing to weedy check. However, at harvest stage weed biomass in the treatments of white and black plastic mulch compared to the weed infested treatment had the highest weeds biomass around 46% in both. The lowest weed biomass was observed in two hand weeding at 20 and 40 DAP by 19.22% after the weedy check. It can be concluded that, the two hand weeding at 20 and 40 DAP and straw mulching with one hand weeding can provide more proper control of weeds compared to the use of herbicides and the use of straw mulches reduces the use of herbicides.
