tailieunhanh - Efficacy of atrazine based post-emergence herbicide mixtures on weed dynamics and maize (Zea mays L.) productivity in sub-humid southern plain of Rajasthan

A field experiment was conducted on clay loam soil during kharif, 2017 at Instructional Agronomy Farm, Rajasthan College of Agriculture, Udaipur to find out the effect of herbicides and their tank mix application on weed dynamics, growth and yield of maize. The post-emergence tank mix application of atrazine kg/ha + tembotrione kg/ha at 15 DAS reduced weed density, weed dry matter and improved weed control efficiency of monocot, dicot and total weed at 60 DAS. The maximum number of cob/plant (), cob weight/plant ( g) and weight of grain/cob ( g), number of grain row/cob (), number of grain/row (), test weight ( g) and shelling percentage () were obtained by weed control through tank mix applicationn of atrazine kg/ha + tembotrione kg/ha at 15 DAS. Similarly, application of atrazine kg/ha + tembotrione kg/ha at 15 DAS also resulted in significantly higher grain, stover and biological yield compared to rest of treatments. Likewise, it was also superior most with respect to all the yield attributes, yield and shelling% as compared to the other treatment. | Efficacy of atrazine based post-emergence herbicide mixtures on weed dynamics and maize (Zea mays L.) productivity in sub-humid southern plain of Rajasthan
