Abstract
Effect of planting methods and nutrient application on a maize hybrid was studied at the University of Agriculture, Faisalabad for two years (1997-98). The planting methods were70 cm spaced single rows, 105 cm spaced doublerow strips and 70 cm spaced ridges. The nutrient levels (Kg ha-') were N (250), N + P (250 + 100), N + P + K (250 + 150'+ 100), N + P + K + S (250 + 150 + 100 + 15), N + P + K + Mg (250 + 150 + 100 + 15) and N + P + K + S + Mg (250 + 150 + 100 + 15 + 15). The crop sown on ridges produced significantly taller plants, more number of grains per cob, heavier grains, higher grain and stover yield with greater harvest index than the crop sown on flat either in 105 cm spaced double-row strips or 70 cm spaced single rows. Among the nutrient levels, application of 15 kg S alongwith 250 -150-100 kg NPK ha-' produced significantly higher grain yield (8.52 t ha-') than NPK alone (8.11 t ha-'). Application of Mg with NPK had no significant effect on grain yield. Key words: Planting methods, nutrient management, hybrid maize
