An experiment was conducted at Balindi Research Complex, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during the winter (rabi) season of 2019-2020 to evaluate the effect of different mulching and nutrient management practices on yield, nutrient uptake and residual soil fertility status of summer maize (Zea mays L.) in slightly alkaline clay loam soil. The experiment was laid out in Randomized Block Design with nine treatment (T) combinations viz.,T1-Live mulch (Trifolium

Experimental findings demonstrated that different mulching and fertiliser levels had a substantial impact on yield, plant nutrient uptake and soil fertility status. Straw mulching along with 100 % RDF (T6) recorded the highest uptake of nitrogen (202.91 kg ha-1), phosphorus (P2O5) (24.03 kg ha-1), potassium (K2O) uptake (102.23 kg ha-1), grain (5.28 t ha-1) and stover yield (7.65 t ha-1) however, treatment T7 recorded the lowest grain and stover yield. So, a combination of straw mulch and 100% RDF could be suggested for improved production and obtaining higher profit for rabi maize with long-term soil health benefits.
