The research method is laboratory-field.To create a multi-cultural agricultural grouping, strips are formed on the square that are multiples of the width of the passage of the unit (for example, 2,8 m; 4,2 m; 5,6 m, etc.). The so-called "companion crops" of continuous sowing are grown in the salted strips - grain spikes (for example, winter triticale - the most optimal precursor for beans), in the non-salted strips - beans. Alternation of crops in crop rotation occurs by periodic change of fertilized and non-fermented strips. An information database has been created on the compatibility of vegetable beans and related crops according to Mix Cropp. The largest number of nitrogen-fixing nodules was noted for the companion crop of winter triticale - 83-110 pcs. on the plant. According to the distance between the rows, their number decreases. In 2022, during the strip cultivation of beans with a side crop of winter triticale and for the predecessor of the bean, also winter triticale, the lowest degree of development of anthracnose was 1,25-2,5 %, alternaria up to 5 %. In 2023, the degree of development of anthracnose was 13-20 % according to the accompanying crop and its predecessor, winter triticale, and 35-40 % according to other options. The plant protection system, both chemical and biological, restrained the development of diseases where winter triticale was the predecessor. The highest yield of bean grain was obtained for the accompanying crop and its predecessor winter triticale – 3,81 t/ha, weight of 1000 seeds - 412-416 g, seed germination - not lower than 90 %.
