Abstract

This paper investigated the effects of different planting geometries and irrigation regimes on wheat yield, water productivity, and growth parameters in Pakistan. The field experiment was conducted at the Water Management Research Station in Faisalabad during the 2019-2020 winter season. The treatments included four irrigation levels (100%, 80%, 60%, and 40% of crop evapotranspiration) and four planting geometries: 60 cm wide raised beds with 2, 3, or 4 rows, and flat sowing with 22.5 cm spacing. The results showed that planting geometry with 3 rows on 60 cm wide raised beds (G2) gave the highest grain yield, biological yield, water productivity, spike length, and grain weight compared to the other geometries. Reducing irrigation from 100% to 40% evapotranspiration decreased yields and growth parameters for all planting methods. Overall, the furrow-irrigated raised bed system with 3 rows on 60 cm beds performed the best in terms of wheat productivity and water use efficiency. Deficit irrigation reduced yields, but furrow-irrigated beds helped conserve water and maintained higher yields than flat planting. The findings suggest that furrow-irrigated raised bed planting with 3 rows on 60 cm beds provides advantages for wheat cultivation in water-scarce regions like Pakistan compared to conventional flat sowing methods. The study demonstrates the potential of this planting technique to improve wheat yields and water productivity under limited irrigation.
