In maize, planting architects play a key role in achieving higher yield by providing improved soil conditions. The present study was conducted with an objective to investigate the yield response of hybrid maize to different architects. Four architects used were as follows: (1) 75 cm spaced ridges, planting on one side of the ridge with 15 cm plant spacing; (2) 90 cm spaced raised beds, planting on both sides of beds with 25 cm plant spacing; (3) 105 cm spaced raised beds, planting on both sides of beds with 21.25 cm plant spacing and (4) 120 cm spaced raised beds, planting on both sides of beds with 18.75 cm plant spacing. Results revealed that days to emergence, days of sailing and ear height did not respond to studied architects. Taller maize plants were recorded in ridge sowing. Higher (P<0.05) grain/ear (696), 1000-grain weight (324.8 g) and grain yield (12189 kg/ha) were recorded in architect-1. Among the bed structures, architect-3 produced taller plants (233 cm), and higher grain/ear (680), 1000-grain weight (296.4 g), and grain yield (11304.3 kg/ha). Therefore, in irrigated conditions of the upper Indus basin, ridge sowing is a better option for spring maize compared to bed sowing.
