Abstract:
Cultivating vegetable crops is convenient in Kazakhstan regarding to suitable temperature conditions during the growing season. Therefore, utilizing effectively technology and equipment during the crop production might improve the efficiency of vegetable industry. However, lack of irrigated water becomes the main factor of delaying development of vegetable producing industry. Thus, an experiment was done on assessing effects of drip irrigated system on economical and yield capacity of tomato during the season 2012-2013. The purpose of the work was to study effects of drip irrigation systems on saving irrigated water and yield capacity of tomato in the growing season in the conditions of south-east Kazakhstan. In the field experiments and laboratory researches following methods are used: technique of agrochemical researches; early phenological phases of development of vegetable technique of a field experiment; technique of skilled business in vegetable growing and melon growing. Tomato cultivars were planted under the scheme of 7030 cm. Fertilizing rates were estimated by N90P120K90. It was found that drip irrigation technology could provide a relatively furrow irrigation where irrigated water savings were 1649 m3 
ha-1. Also the method helped to increase yield for 14.7 t ha-1 by reaching to the level of 51.9 t ha-1. Consequently, utilizing of drip irrigation system for growing tomato cultivars in the conditions of the south east of Kazakhstan can assure irrigated water savings by 40.96% and increase yield of cultivars 39.52%, which increases the competitiveness of the horticulture industry in the country.
