Effect of organic nutrient and weed management practices on growth, yield attributes and yield of rabi sweet corn (Zea mays L. saccharata) under vertisol of Chhattisgarh

Abstract

A field experiment become performed on the research-cum educational farm, college of Agriculture, Raipur (C.G.) at some stage in the rabi season of 2018-19. The test changed into laid out in break up plot layout with 3 natural nutrient control alternatives in principal plots and 7 weed control alternatives in sub plots. The treatments consisted of 50% N (FYM) + 50% N (vermicompost); 50% N (FYM) + 50% N (hen manure); 50% N (FYM) + 25% N (vermicompost) + 25% N (poultry manure) and weed manage options hand weeding twice (20 and 40 DAS);black polythene mulch, straw mulch @ five tonne ha-1; mechanical weeding two times (20 and forty DAS); stay mulch (in-situ incorporation of green gram at 30 DAS); atrazine 1.0 kgha-1as pre-emergence and weedy take a look at. sweet corn “Sugar seventy five” changed into taken as test crop. The effects of experiment discovered that every one the growth, yield attributes parameters and green cob yield had been significantly better underneath 50% N (FYM) + 50% N (poultry manure) and underneath black polythene mulch. drastically lowest values were received in 50% N (FYM) + 50% N (vermicompost) in weedy check remedy.
