Abstract:

Present investigation was undertaken to study weed growth, yield and nutrient uptake in maize under varied weed management practice during winter season under irrigated conditions. Reduced weed dry matter was noticed significantly in farmers practice (HW at 20 and 40 DAS), which was comparable with black and white polythene mulch (25 µm thickness UV resistant). Application of black polythene mulch showed significant increase in crop dry matter at physiological maturity stage. highest N, P and K removal was noticed with black polythene mulch and was at par with white polythene mulch and farmers practice for grain nitrogen, whereas for grain P and K, higher removal was observed with black polythene mulch. Significantly more grain yield was obtained under black polythene mulch, which was comparable with grain yield of white polythene mulch, farmers practice (HW at 20 and 40 DAS) and pre-emergence application of atrazine 1.0 kg/ha fb 2, 4- D sodium salt 1.0 kg/ha at 30 DAS.
