When applying sulfoammophos in rows in the amount of 0.7-1.0 t/ha (physical weight) during sowing, it helps to increase the yield of winter wheat by 6.3-7.2 t/ha, spring barley by 8.1-14.2 t/ha.

• The main introduction of sulfoammophos in a dose of 3.0 t/ha increases the productivity of second winter wheat by 11.0 t/ha or 23%, spring barley by 5.6 t/ha, sunflower by 1.3 t/ha. The use of sulfoammophos contributes to an increase in the amount of raw gluten in winter wheat grain by 2.7%.

• The increase in the yield of the green mass of corn is 42.6 t/ha, which significantly exceeds the effect of the mixture ofammophos andammonium nitrate, introduced in an equal dose.

• When applying sulfoammophos under corn on grain, the largest increase in grain yield was obtained - 6.1 t/ha.

• The use of sulfoammophos whenseeding sunflowers, despite the deficit of available moisture, gives an average increase of 2 t/ha for hybrids.
