Soybean (Glycine max L. Merr) crops were grown in 2013-2015 to determine effect of drip irrigation in the different variants water levels with using mulch on growth and productivity under conditions of the south-east of Kazakhstan.The use of mulch in agriculture has increased in last years throughout the world.This article presents the outcome of field experiments conducted in the Kazakhstan on the effects of drip irrigation (DI) practices on reproductive stages of soybean.Drip irrigation with or without mulch was adopted for the experimental plots.The most effective way to combat weeds in soybean crops proved to drip irrigation under mulch film, where the number of weeds in the early growing season did not exceed 36-44 units / m 2 .Despite the prevailing adverse weather conditions for the growth and development of soybean in the south-east of Kazakhstan, we have received a fairly high yield (42.2 tonnes / ha) on a variant using a mulching film.The results indicated that use mulch under drip irrigation significantly increase plant growth and production soybean.This increase is due to benefits such as increase in soil temperature, reduced weed pressure, moisture conservation, reduction of certain insect pests, higher crop yields, and more efficient use of soil nutrients.
