The Effect of Different Weed Management Strategies on the Growth and Yield of Direct-Seeded Dry Rice (Oryza sativa)

Abstract: -Weed management is a primary concern in direct seeded rice (DSR) cropping because weed growth becomes a major constraint on crop yield. A two year field study was set up to evaluate the effect of various weed control measures on crop growth, grain yield and grain quality of DSR. The experiment involved five different weed control measures: hand weeding, hoeing, inter-row tine cultivation, inter-row spike hoeing and herbicide treatment (Nominee 100 SC). The extent of weed control (compared to a non-weeded cont… Show more

“…A signifi cantly higher weed index was recorded in weedy check (59.25% and 84.44%) over all the other treatments (Table 02). The results were in conformity with earlier fi ndings where higher weed biomass was linked to zero weed control measure on weed growth (Olayinka and Etejere, 2015;Muhammad et al, 2016). The lowest weed control effi ciency recorded in sole Pendimethalin at 4lha -1 when compared to treatment such as two hand weeding at 3 and 6 WAT and Pendimethalin at 4lha -1 + one hand weeding at 6 WAT was due to inability of the herbicide to provide continuous weed control.…”

“…As far as weeds concerned, transplanted rice has a clear edge over DSR (Chauhan and Johnson, 2009;Chauhan, 2012). Hence, among various factors affecting rice growth like fertilizer management and sowing dates (Abid et al, 2015), weed invasion is one of the most severe problems in aerobic rice (Khaliq et al, 2012, Muhammad et al, 2016Ullah et al, 2017) which caused reduction in grain yield up to 80% in DSR (Mahajan and Chauhan, 2015). DSR can be sown into a prepared seed bed or under zero-till (ZT) conditions which depends upon the production system.…”

“…Direct seeding of rice (DSR) requires less water and labour as compared to flooded rice (Weerakoon et al, 2011). But the only drawback of DSR is weed infestation which substantially reduces the yield potential (Muhammad et al, 2016); as weeds are notorious competitor of rice and major constraint in adaptation of direct seeding (Saqib et al, 2015). Weeds nurture comparatively with impressive growth in DSR compared to flooded rice system and sometimes results into complete crop failure (Phoung et al, 2005).…”
