Abstract
Weeds pose a major challenge to crop productivity, significantly impacting maize (Zea mays L.), which is Nepal’s second-most important staple crop. Although attainable yield 5.8 t ha⁻¹, the national average is only 3.15 t ha⁻¹, largely due to issues like weed competition that can lead to yield losses of up to 48%. This study, carried out during the winter season at the National Maize Research Program in Rampur, Chitwan, evaluated nine different weed management treatments, weedy check, weed free, green polythene mulching, clear polythene mulching, cowpea co-culture, black polythene mulching, atrazine + one hand weeding @ 30 DAS, silver black polythene mulch and Lantana camara as mulch in a randomized complete block design with four replications. The results showed that mulching methods, particularly silver-black polythene mulch, significantly enhanced growth parameters, grain yield (4,537.5 kg ha⁻¹) and stover yield (6,500 kg ha⁻¹). Furthermore, mulching facilitated earlier tasseling (73.19 DAS) and silking (85.31 DAS), while also improving soil moisture retention, and weed suppression. Both clear and black polythene mulches had beneficial effects on growth and yield. Similarly, grain yield in Lantana camara as mulch and Atrazine @ 0.75 kg ha-1 + one hand weeding also remain same with clear polythene mulch.
