Wheat (Triticum aestivum L.), being the staple food of Pakistan is in high demand in order to achieve the food necessity of people, yet owing to biotic and abiotic stresses, its yield is decreasing drastically. Climate change has caused a shift in crop maturity duration and ultimately impacts grain yield. In order to achieve a sustainable balance in crop yield, the emphasis on biotic stress factors should also be focused. Weeds hoist yield loss, create physiological and biochemical imperfections and cause crop losses through competition and allelopathic interactions. This study was designed to evaluate weed control in wheat crops by adopting cultural control practices. The research was carried out at Regional Agricultural Research Institute Bahawalpur from 2022 to 2024. This trial comprised of six treatments viz. sowing of wheat under 15 cm apart single row spacing, 15 cm apart cross row spacing, 30 cm apart single row spacing with increased seed rate, 30 cm apart cross row spacing with increased seed rate, chemical treatment and comparison with control was made. RCBD factorial design with three replications was used to evaluate the trial statistically. Growth parameters were observed along with Principal component analysis. The results revealed that 30 cm apart cross row spacing with increased seed rate provided highest grain yield (4770.8 kg/ha) followed by chemical control (3905 kg/ha) and 15 cm apart cross row spacing (3879 kg/ha). The results of this study rendered positive aspects for farmers who lack economic resources for weedicide, as well as discouraged use of herbicide thus ensuring sustainable agricultural practices.
