Abstract
An experiment was conducted during kharif season of 2014 at crop cafeteria form of Krishi Vigyan Kendra, Jaunpur to assess the effect of different weed control methods to yield of low land rice (Oryza sativa L.). Weed competition will reduce rice yield. It has been conducted from 15 June 2014 until October 2014 with variety Pusa Sugandha-5 (It is non basmati variety but aromatic) nursery was done on 15 June and 23 days old seedling were transplanted. The experiment laid out using Randomized Block design with five treatments (A = unweed control (Weedy check), B = manual weeding (Two hand weeding), C = herbicide containing Penoxulam + Cyhalofop- butyl, D = Bispyribac sodium, and E = 2, 4 D + Methyl metsulfuron). The results showed that weed control using herbicides containing Bispyribac sodium and 2.4 D + Methyl metsulfuron showed similar results as manual weed control on rice yield. The maximum weed index was observed in weedy check plots.
