The article presents the results of a study of soil water regime and use of soil moisture by winter

wheat at the cultivation on such predecessors as black fallow and maize for silage in the southern zone of

the Rostov region. The main source of winter wheat water supply is precipitation; therefore an analysis of

meteorological conditions for 2004-2013 was carried out. Water regime of plants of winter wheat during

years of research developed under the influence of different moisture supply. During the growing season

(September-June) the demand of wheat in water provided with precipitation for 82%. The amount of pre-

cipitation satisfies the 100% needs in water only three years out of ten. The coefficient of moisture supply

of winter wheat plants in different years varied on black fallow predecessor from a 0.67 to 1.41 units and

on corn for silage predecessor from a 0.56 to 1.28. Best conditions of moisture supply on the predecessor

black fallow promote to obtaining high grain yields – 4.79…7.00 t/ha depending on the year of studies.

Grain yield of winter wheat on the corn predecessor did not exceed a 4.24…5.31 t/ha which is associated

with a lower supply of plants in this variant. Gross consumption of moisture by plants of a winter wheat

on black fallow predecessor averaged 419 mm that is 62 mm higher than on corn for silage predecessor.

The total consumption of water per unit of crop (774 m


/t) for the black fallow predecessor was 15%

lower than for the corn for silage predecessor (909 m3/t). The proportion of precipitation in the

total water consumption of winter wheat ranged from 70 to 87%: of soil moisture from 30% to

13% respectively depending on the previous crop.

Key words: precipitation, water demand, winter wheat, moisture supply, predecessor, yield,

consumption of moisture
