“…Manual weeding is one of the effective methods for weed control during the critical period. But timely weed management has become difficult due to unavailability of man force and escalating wages during peak period [3]. Hence, herbicides are considered as alternative and effective weed control measure to implement in larger area than hand weeding.…”

Aim: Field experiment was conducted to study the suitable weed management methods to check the nutrient depletion by weeds, check the dynamics of microbial population and in relation to improve the biomass stover yield of maize (Zea mays L.). Study Design: This experiment laid out in a randomized block design and 8 different weed management treatments with three replications. Place and Duration of Study: Field experiment was conducted at Agricultural College and Research Institute, Madurai, Tamil Nadu Agricultural University, Tamil Nadu in kharif 2019. Methodology: TNAU maize hybrid CO-6 was used for this experiment. Treatments were application of pre-emergence herbicide atrazine at 0.25 kg/ha or pendimethalin 1 kg/ha applied singly on 3 days after sowing and in combination with post-emergence herbicide tembotrione 120 g/ha or halosulfuron methyl 90 g/ha on 25 DAS, weed free check, unweeded check in maize crop. Weed nutrient depletion and microbial population was analysed in laboratory. Results: The application of pre-emergence atrazine 0.25 kg/ha followed by post-emergence tembotrione 120 g/ha effective in controlling of grasses and BLW and enhance the nutrient uptake of maize. The stover maize yield increased with application of herbicides and sequential application of herbicides achieved 88% improved stover yield over unweeded check. Sequential application of herbicides initially reduce the population of soil microflora but the population gradually build up in all the herbicide applied plots at 60 days after application. Conclusion: Based on the results of the experiment, it was concluded that pre-emergence atrazine 0.25 kg/ha followed by post emergence tembotrione 120 g/ha effective in controlling of weeds and enhance the nutrient uptake and stover yield of maize without much adverse impact on soil microbial population.

“…Digitaria sanguinalis. Paul et al[47] also identified major weeds in experimental field of Madurai, Tamil Nadu and weeds identified under broad leaf weed were Boerhavia erecta, Acalypha indica, Commelina benghalensis, Cleome viscosa, Eclipta alba, Cannabis sativa L., Polypogon monspeliensis L. and Cynodon dactylon L. were among the top infesting weeds that Roy et al[54] discovered in weedy check. According to Singh et al[60],…”

Farmers are subjected to yield loss due to different reasons including weed invasion. As weed management is a major approach different methods are incorporated for their management like cultural, mechanical and chemical, etc. Different strategies are required for eradication as cultural methods can’t be used in large area as application of herbicide or tillage methods are found effective in such conditions. Use of compatible herbicides is necessary as they have different way of approach to weeds as different weed species are observed on field. From this review it is concluded that cultural as well as chemical means both are effective when used in a significant manner and application is done according to land area taken into consideration.
