Weed Management Practices in Maize (Zea mays L.): A Review

Abstract

In India the highest loss (33%) is caused by weeds, followed by pathogens (26%), insects (20%), storage pests (7%), rodents (6%) and others (8%). Weeds compete with the crop for both above and below ground resources. Critical period of weed competition starts from 17 to 29 days after planting of corn, at an acceptable yield loss of 5 to 10 per cent. Herbicides are efficient tools for checking weed infestation and its usage is increasing throughout the globe due to increasing labour cost and quick weed control in various situations. The common weed management practice for Maize is pre-emergence application of selective herbicides like atrazine or pendimethalin followed by one hand weeding. Managing weeds through pre-emergence, post-emergence and sequential use of herbicides will be an ideal means for controlling the weeds in the view of economics and effectiveness in maize.

"Effect of Weed Management on the Growth, Yield, and Quality of Summer Maize "

“…The lowest plant height and lesser leaves per plant in unweeded plots might be due to more competition between crops and weeds for moisture, nutrient, light, and space. These indings are in agreement with those of Arvadiyaet al (2012),Rani and Sagar (2013),Mahadi (2014), Innaliet al (2014), Samantet al (2015,Rao et al (2016) andHargilas (2019). Different weed management treatments had a signi icant effect on a number of cobs per plant and maximum cobs per plant (1.79) were recorded with treatment T (weed…”

Influence of different sources of fertilizers and weed control treatments on growth, phenology, and yield of baby corn (Zea mays L.) in semi-arid of India

“…Moreover, this could be attributed to effective weed control in the herbicide treated plots which resulted in maximum nutrient utilization and led to the production of high assimilation of photosynthates, causing an increase in the yield of baby corn. Supporting this finding is [10,13,[16][17][18], who observed an increase in yield attributes of maize in herbicide-treated plots over the weedy check.…”
