Abstract: Field experiment was conducted at Indira Gandhi Krishi Vishwavidyalaya, Raipur during kharif, 2017 to study the Performance of maize under different lateral arrangements and nutrient management practices using drip irrigation system. The lateral arrangements and conventional practice and four nutrient management (50, 100, 150% RDF and STCR- based fertilizer recommendation) were included as treatments in this study. Crop imposed with lateral at 45 cm (W₁) recorded maximum protein yield and growth parameters viz. plant height, numbers of leaves plant ^-1, stem girth, leaf area index, dry matter accumulation, crop growth rate (CGR) and relative growth rate (RGR) at 0-30 days while lowest protein yield and growth parameters were recorded under conventional practice (W₃). In respect to nutrient management, STCR- based fertilizer recommendation (N₄) recorded maximum protein yield and growth parameters and it was found statistically at par with 150% RDF (N₃). However the minimum protein yield and growth parameters were recorded under 50% RDF (N₁). Thus study revealed that, lateral arrangement at 45 cm (W1) with STCR- based fertilizer recommendation (N4) could be the optimal management practice for obtaining higher protein yield and growth parameters of maize.
