Assessing the Effect of Weed Management Practices on Weed Flora, Growth and Yield of Fodder Maize

A field experiment was administered at Research Farm, AICRP on Forage Crops, Department of Agronomy, JNKVV, Jabalpur (Madhya Pradesh) during of the old age 2019. The main objective of the experiment was to discover the effect of different grass control treatments on complex grass flora in grain maize. Ten treatments were proven in randomized block design with three replications. Treatments contained pre-emergence application of atrazine 1000 g/ha, pendimethalin 750 g/ha, atrazine 750 g/ha + pendimethalin 750 g/ha and post rise application of 2, 4-D 500 g/ha, tembotrione 120 g/ha, topramezone 35 g/ha, tembotrione 120 g/ha + atrazine 250 g/ha, topramezone 35 g/ha + atrazine 250 g/ha, help weeding double at 20 and 40 DAS and weedy check. Weed force and dry matter accumulation by weeds were written species reasonable and then the influence of weed administration and the weed control adeptness were calculated. In maize field, the predominated weeds were Echinochloa colona, Commelina communis, and Digitaria sanguinalis with monocots, Phyllanthus niruri and Eclipta alba among dicots in addition to a respectable total of numerous minor weeds. Experimental results determined that hand marriage has recorded highest grass control efficiency (88.64%) understood by PoE application of topramezone 35 g/ha + atrazine 250 g/ha (74.38%) and tembotrione 120 g/ha + atrazine 250 g/ha (68.31%). All grass control treatments considerably affected the plant altitude, LAI, stem girth and leaf: stem percentage of crop. Among different herbicidal situations, topramezone 35 g/ha + atrazine 250 g/ha was found considerably superior and gives highest green barley yield (47.26 t/ha), dry fodder yield (13.64 t/ha), coarse protein yield (1.51 t/ha), net monetary returns (Rs. 44824/ha) and B: C percentage (2.72). Thus, herbicide request of topramezone 35 g/ha + atrazine 250 g/ha was found more trustworthy to control complex weed vegetation of fodder maize with bigger green fodder yield and net returns.
