tailieunhanh - Effect of conservation agricultural practices on candidate herbicides persistence under maize-sunflower system in tropical Indian conditions

Conservation agriculture (CA), an input saving concept has gaining momentum in India to address the labor shortage, soil health and sustaining crop productivity. However the adoption of CA practices has issues of poor weed control, increased herbicides application etc. due to loss of efficacy. This may also alter the persistence and dissipation behavior of herbicides in soil. Hence field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore during 2014-16 to study the influence of different combinations of CA practices and weed management methods on the persistence of atrazine and pendimethalin applied to maize-sunflower cropping system. The experiments were laid out in strip plot design with three replications. |
