This scientific article shows the results and results of research on harvesting quality crops efficiently and repeatedly in the condition of water shortage, as well as irrigating system with supply of different quality water in order to improve the reclamation of lands. The study shows the results of experiments of the irrigating systems and the impact of irrigation water on the growth and yield of replanted millet in the grassland alluvial soils of Bukhara region, where the groundwater level is 1.5–2.0 meters. In the first experiment the mineralization of the drainage water was 4.1 g/l in the field that has been controlled and the seasonal irrigation rate of millet was 2580 cbm/ha. In the second experiment, the mineralization of irrigation water which has been taken from river was 0.9 g/l, and the seasonal irrigation norm was 2372 cbm/ha. In the third experiment, the mineralization of irrigation water which has been combined river water with the ditch water was 2.3 g/l and the seasonal irrigation norm was 2485 cbm/ha, while in the fourth experiment, the mineralization of irrigation water to which biosolvent has been added for the seasonal irrigation norm was 2464 cbm/ha. The yield of replanted millet was 2.6 t/ha in first experiment, 2.71 t/ha in second one, 2.66 t/ha in third experiment, and the yield of millet in the last experiment was 2.68 t/ha. High economic efficiency was observed in the third experiment.
