Influence of Pre-Sowing Irrigation on Seed Generation in Winter Wheat

Abstract

The effect of pre-sowing irrigation on the germination of wheat seeds was studied during the autumn sowing of varieties from the regional nursery of Central Asia and Kazakhstan. Pre-plant irrigation and seeding on moist soil resulted in stronger seedlings and a larger and deeper root system compared to seeding on dry soil and watering after seeding. The average germination of seeds in the control variants for all varieties sown in three agility on dry soil and row irrigation after sowing was 76.7% or an average of 200 seeds per square meter, and with presowing irrigation it was 83.4% or, on average, 20 seeds more than control. The highest water use efficiency and seed germination were observed when planting on moist soil, suggesting that the combination of preplant irrigation and phosphorus application had a beneficial effect on germination and seed retention of wheat.
