As a result of introductions of unconventional annual feed crops of Paiza and African millet, the influence of bioclimatic conditions and agrotechnical measures (seeding rate, sowing time, and irrigation) on the formation of green and dry weight and seeds in the steppe zone of Northern Kazakhstan was studied. The sum of active temperatures for the formation of yield of green and dry mass and seeds of the first and second time of sowing was sufficient, and at the third planting period there was a deficit of temperatures. For African millet, it was sufficient for all sowing dates. Humidification conditions had a strong impact on the productivity of both paiza and African millet, as high yields of green and dry weight and seeds of these crops were obtained during irrigation. The yield of paiza and African millet depended on the seeding rate: the greater the density of standing plants, the higher was the yield of green and dry mass and seeds, and it was for paiza 12,3, 3,0 and 2,2 t/ha, for African millet -19,9, 5,0 and 3,4 t/ha. Due to the highest moisture availability, the maximum yields of green and dry weight of the paiza were noted during the second planting period and were respectively 15,8 and 4,3 t/ha, seed yield was greater during the first term of sowing – 2,6 t/ha. Crops of African millet formed the highest yield of green and dry mass, as well as seeds with the first term of sowing – 23,9, 5,8 and 4,2 t/ha. Irrigation provided a yield increase of th
e green mass of paiza and African millet in comparison to the variants without irrigation of 22,0 and 16,4 t/ha, the dry mass – 5,2 and 3,3, and the seeds – 2,2 and 1,2 t/ha respectively.
