An important factor in increasing the efficiency of crop diversification in West Kazakhstan and
reducing the dependence of crop productivity on weather conditions is the expansion of crops most adapted to
unsustainable humidification of plants such as chickpeas, Sudan grass, sorghum, corn and sunflower. One of the
ways to increase the productivity of Sudanese grass is to use its mixed crops with chickpeas, sunflower, corn and
sorghum. Mixtures due to the best quality indicators of feed provide the maximum yield of feed units and digestible
protein. The article presents research data on the study of mixed crops of Sudanese grass with annual crops in the
conditions of the 1st dry-steppe zone of Western Kazakhstan. A comparative test of mixed crops by yield from
digestible protein area units revealed the most nutritionally valuable mixtures. So, in the research of 2018-2020, the
largest yield for digestible protein was obtained on the variant using sunflower for silage mixed with Sudan grass
(1.65 c/ha), slightly lower on the versions of using a mixture of Sudan grass and corn for silage (1.58 c/ha) and a
mixture of sorghum and Sudan grass for silage (1.55 c/ha).
