METHOD OF CULTIVATING SUDANESE GRASS ON GREEN MASS ON RECLAIMED LANDS OF KALMYKIA

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, in particular to farming. Method involves sowing Sudanese grass in early May with sowing norm of 4.5–5 million pieces/ha, maintaining pre-irrigation soil moisture content of not less than 75–80 % HB and watering with sprinkling. Differentiated soil treatment system is implemented: after removal of precursor, stubble stubbing in 1–2 traces; autumn plowing at depth of 0.22–0.25 m for heavy and medium loamy soils and 0.20–0.22 m for light loamy soils; spring-weaving or unreeling till depth of 0.18–0.22 m – on sandy and sandy soils; pre-sowing cultivation, presowing and post-sowing rolling.;EFFECT: method makes it possible to increase productivity of green mass of Sudanese grass to 25–30 t/ha.;1 cl, 2 tbl
