Abstract:
A field experiment was carried out at Research block of S.G.R.R University, Dehradun, Uttarakhand during Rabi season of 2019-2020 to record the response of various weed management methods on growth and yield of Potato (Solanum tuberosum L.) The experiment was carried out in Randomized Block Design (RBD). Eight treatments were adopted for the experiment with three replications each. Kufri Jyoti is an early maturing variety in hills. The major weed species observed during the course of the experiment were Cyperus rotundus (sedge), Eleusine indica and Digitaria sanguinalis among grassy weeds and Medicago denticulata, Chenopodium album and Amaranthus virdis among broad leaf weeds. The results stated that treatment T2 (Pendimethalin 350 g ha-1 as pre-emergent application) was most effective in controlling weeds and recorded with highest weed control efficiency (47.84 %), highest number of tubers (96.00) and maximum yield (61.5 Kg). Besides, minimum dry biomass of weed (29.59 g m-2), lowest weed density per meter square (61.25 m-2) at 60 Days after sowing (DAS) and at harvesting stage of crop (54.97 m-2) were recorded under Treatment T2 (Pendimethalin 350 g ha-1 as pre-emergent application). Whereas, treatment T1 i.e. weedy check (control), was least effective in controlling weeds and also recorded maximum weed density m-2 at 60 DAS (110.31 m-2) and at harvesting stage (97.31 m-2). T1 also recorded maximum weed dry biomass (56.73 g m-2) and showed lowest yield (30.90 kg).
