Chemical Weed Management in Maize (Zea maysL.) under Conservation Agricultural Systems: An Outlook of the Eastern Gangetic Plains in South-Asia

Abstract

Maize is a widely grown cereal after rice and wheat and contributes almost 5% to the global dietary supply. In the Eastern Gangetic Plains (EGP) including India, Bangladesh, and Nepal, maize is an emerging cash crop, because of its high yield potentiality and also the favorable climatic conditions which allow maize production round the year. In Bangladesh, area and production of maize are escalating due to the increasing demand for poultry, livestock, and fish feed, and fodder for animals and starch industries in the region. Presently, more than 90% of maize is planted by manual dibbling following 5-6 intensive tillage, which increases the cost of cultivation. The conservation agricultural (CA)-based new agricultural practices could overcome those above challenges. CA is cost-effective and environmentally friendly; however, weeds are one of the key challenges in the system. The chapter described the uses of herbicides in different ways of combinations to make effective weed control in CA-based maize to achieve potential production and profits by reducing the intensive pressure of manual weeding. The efficient and right use of pre-plant/sowing, pre-and post-emergence herbicides and their combination may be the best way for effective control of weeds in maize production.

Journal of Plant Protection Research

“…The weed community in maize can include many species, but it is generally dominated by a few species that are most abundant, spread the best and have the strongest effect on the crops, limiting its growth, development and yield (Iderawumi and Friday 2018). Species occurring during our own study belonged to the most common weed community in maize fields and competed strongly with it (Hossain et al 2019).…”

Use of anti-transpirants in maize cultivation as a potential novel approach to combat drought stress in the wake of climate change. A systematic review

“…Zea mays L., also known as maize, is the third most significant staple food crop in terms of global production [1,2,3]. According to Petrovi et al [4], its global production hit 1.1 billion tons in 2019.…”

Effects of weed management on agronomic performance and productivity of hybrid maize (Zea mays L.)

“…Utilization of herbicides after the germination of field crops and weeds is referred to as postemergence herbicides. Post-emergence herbicides can be sprayed or applied on the canopy of weed in the field of maize by utilizing the sprayer tool (Hossain et al, 2019).…”
