Maize is one of the most important cereals crop worldwide and is known as the “queen of cereals”. This is because of its very high economic values and also can grow under maximum diverse environments of India as well world. In the light of the above a field experiment was conducted under a split-plot design with three levels of row spacing i.e., S₁, S₂, and S₃ with the four levels of mulching i.e., no mulch (M₀), paddy straw mulch (M₁), green weed mulch (M₂) and dust mulch (M₃). The study was done to find out the effect of row spacing and mulching on the nutrient uptake of maize during two constitutive years (2019, 2020) in eastern Uttar Pradesh. The effect of row spacing and mulching on the nutrient uptake i.e., N, P, K, and S in the maize were observed significant responses during both the year of experimentation. The treatment responses were found significantly better amongst all the treatments of row spacing and it was chronicled in the descending order as S₂>S₁>S₃ except sulphur which was in order S₃>S₂>S₁. However, with the mulching effect, it was recorded in the descending order as M₁ > M₂ > M₃ > M₀ throughout both the years of experimentation. The interaction between row spacing and mulching was significant and was in a similar order to mulching results. The above results row spacing and mulching might be due to the better release of nutrients due to the effect of the treatment.
