Abstract (English):
The data of a three-year experiment to establish the optimal irrigation regime of amaranth varieties Kizlyarets in the sowing on medium saline soils of plain Dagestan. Analysis of the data on leaf area showed that the maximum results were recorded on crops in wide way of planting with a spacing of 45 cm and a minimum on crops with a row spacing of 70 cm. When comparing the options for irrigation regime, it was revealed that the best results were recorded when pre-irrigation moisture threshold 80-85% of the smallest moisture capacity, and the mode of irrigation at 60-65% is much lower. The higher yield of amaranth was also at the irrigation regime pre-irrigation threshold of 80-85% of the lowest moisture capacity, with a wide – row method of sowing with row spacing of 45 cm-up to 35 tons per hectare.
