Productivity of mixed chickpea forage crops with grain and leguminous crops when cultivated for grain fodder

In modern agricultural production, the most acute problem is the production of vegetable protein. Leguminous crops and their mixed crops with cereals play an important role in solving this problem. However, the share of leguminous crops in the Siberian region in the structure of crops does not exceed 1.0-1.5%, against 8-10% recommended by science. The research was carried out for three years in the southern forest-steppe zone of the Omsk region at the training and experimental field of the Omsk State Agrarian University. The soil of the experimental site is meadow-chernozem thin low-humus medium loamy with a humus content of 3.4%, P2O5 - 28.4 and K2O - 22.5 mg/100 g of soil; pH - 6.7-7.4, groundwater level - 2.5-4.5 m. The purpose of the research is to identify the most productive mixtures of chickpeas with grain and leguminous crops to obtain grain fodder in the conditions of the forest-steppe zone of Western Siberia. It has been established that in the conditions of the southern forest-steppe zone of Western Siberia, along with a pea-oat mixture, it is possible to successfully cultivate mixtures of chickpeas with grain and leguminous crops. Mixed chickpea crops have a stable yield of feed grain over the years, the coefficient of variation is insignificant - 5.1-7.0%. Of the mixed chickpea crops with grain and leguminous crops, its crops with wheat and oats are the most productive: grain yield reaches 2.32 t/ha, protein harvest - 320 kg/ha. Sowing chickpeas mixed with leguminous crops provides grain yields 35-78% less than with wheat and oats, but the share of chickpeas in the total grain harvest increases from 22-43 to 44-63%, and protein harvesting - up to 363 kg/ha.
