Abstract

A field experiment was carried out at Agricultural Research Farm, Institute of Agricultural Sciences, Varanasi during kharif 2017 and 2018 to evaluate the nitrogen intake by transplanted rice (Oryza sativa L.) and the available nutrient status of soil under ten weed control treatments. The treatment bispyribac-Na 9.1% (24.57 g/ha) + metsulfuron-methyl 1.2% (3.24 g/ha) + chlorimuron ethyl 1.2% (3.24 g/ha) recorded higher Organic carbon (0.47%), pH (7.38), EC(0.18 dS m-1), available N193.48 kg/ha, P22.46 kg/ha, and K 221.56 kg/ha in soil, higher nutrient (N, P and K)  content in grain 1.14, 0.33, 0.38%,  and straw  0.74, 0.12, 1.74% and protein content 6.81 & 4.42% in grain and straw, respectively. improved N, P, K uptake in grain 58.57, 17.06, 19.23 kg/ha and straw 71.00, 11.36, 166 kg/ha, respectively over weedy check (grain 46.09, 13.35, 15.10 kg/ha and straw 58.58, 9.38 and 137.65 N, P and K respectively). This treatment exhibited positive performance of soil fertility and N, P and K uptake by transplanted rice.

Keywords: Available nutrients, bispyribac-Na, chlorimuron ethyl, metsulfuron-methyl, organic carbon
