Abstract With increasing demand for rice production and a severe shortage of water, it is necessary to develop innovative water-saving technology of rice cultivation which would allow reducing water consumption and increasing rice productivity. Therefore, field experiment was conducted at Agricultural Research Station of Russian Research Institute of Irrigated lands (Volgograd, Russia) over three years (2013-2015) to study the effect of different water regimes viz I1 [80% FC & h = 0.6 m], I2 [80% FC & h = 0.4 and 0.6 m] & I3 [80-70% FC & h = 0.4 and 0.6 m] in combination with three levels of mineral fertilizers (NPK) such as;1- (N109 P62 K75); 2 – (N131 P74 K90) and 3 – (N157 P90 K108) kg ha-1 under drip irrigation system on growth, yield of aerobic rice and water-saving capacity of this technology. The obtained results revealed that, average rice grain yield was 6 ton/ha, while the volume of required irrigation water varied within 499–538 mm/ha which decreased by 60–80% compared to those consumed under the flooding technology of rice cultivation. Therefore, it can be concluded that drip irrigation is characterized by great water saving capacity along with high productivity of aerobic rice varieties. |
