Abstract


The results of researches of drop irrigation of potatoes in Oman depending on a threshold of preirrigation humidity of the soil and creation of a water heat-sink layer are presented. It is established that at maintenance of the differentiated threshold of preirrigation humidity of the soil the most effective use of irrigating water is provided and high productivity of potatoes is reached. It is established that increasing level of preirrigation humidity of soil during the vegetative period from 70 to 80% yield of potatoes can be increased on the average by 26,2%. Artificial formation of water accumulative zone by application of sapropel and bentonite clay promotes decrease in expenses of irrigation water by 5—6% and increases the potato yield by 10—11% and 3—5% respectively.
