Feeding re-crops with optimal rates and efficient use of irrigation water provides a high yield from lands prone to irrigation erosion. The obtained three-year data revealed that in the initial phases of plant development, irrigation methods and fertilization rates did not have a significant effect on plant growth. In subsequent phases, there is a significant difference between the options. The obtained yield data of repeated crops show that on the 2nd option without the introduction of mineral fertilizers and with irrigation in the usual way, the yield of soybean grain was 10.9 c/ha, and on the option with the introduction of mineral fertilizers at the rate of N50 P75 K50 kg/ha, the yield increase grain was 7.2 c/ha. On the variants with zigzag irrigation, the grain yield was higher by 1.1–1.2 c/ha.
