Shatkovsky A. Substantiation of carrot microirrigation technology elements in conditions of a South of Ukraine

In dissertation work are presented theoretical generalization and practical substantiation of carrot microirrigation technology elements on a average loamy soils of South of the Ukraine. Experimentally have proved high efficiency of microirrigation systems usage for carrot cultivation. Determined indices of water consumption depending on method of irrigation and underirrigation humidity of root sphere of soil, investigated influence of method of irrigation on a microclimate. In dissertation have proved a possibility and efficiency of plant protection preparates entering with irrigation water on a system of microsprinklers irrigation, in a field conditions determined parameters of vegetables microirrigation systems work and presented economical estimation of elements of carrot microirrigation technology. Determined that higher productivity and economical efficiency providing under combined influence of such factors of intensification as a microsprinklers irrigation or drip irrigation simultaneously witha differentiated level of underirrigation soil humidity (80-70% MC) and application of fertilizers with an irrigation water.
