ABSTRACT
Wheat productivity could be improved by ridge sowing with optimized seed rate for different varieties. This 3-years study was conducted to determine the optimum seed rate for different varieties of ridge sown wheat for better yield and related components. Wheat varieties (Faisalabad-08, Punjab-11 and Galaxy-13) were sown on ridges using two different seed rates (125 and 150 kg ha-1). Increase in seed rate improved the emergence (plants per m2), number of productive tillers per m2 and grain yield (3-7%) of all wheat varieties although productive tillers per plant, number of grains per spike and 1000-grain weight was decreased. Faislabad-08 performed better regarding grain yield and related components among all varieties. Seed rate and varieties did not interact significantly for studied traits. Correlation analysis revealed that grain yield was positively correlated with number of productive tillers per m2 during all years and grain weight during first year; while, negatively correlated with number of grains per spike during second year indicating that increase in grain yield was associated mainly with increase in number of productive tillers per unit area in response to seed rate. In conclusion, increase in seed rate improved the grain yield of ridge sown wheat by enhancing the number of productive tillers per unit area and could be exploited to improve the wheat productivity.
