Yield of cabbage depending on the irrigation regime in the foothill subprovince of Dagestan

Abstract

Relevance. The main producers of cabbage in Dagestan are personal subsidiary farms of the Mountain subprovince. An additional reserve of production is the Foothill subprovince (in particular buinak district), soil and climatic conditions which are favorable for growing cabbage. In this regard, studies aimed at studying the adaptive potential of cabbage varieties in this subprovince are relevant.Material and methods. The aim of the work is to develop elements of technology for growing varieties of cabbage in relation to the Foothill sub-province of the Republic of Dagestan. The results of three-year studies on the adaptive potential of cabbage varieties in irrigation conditions of the Foothill sub-province of the Republic of Dagestan are presented.Results. As a result of the conducted researches it is revealed that the variety Nadezhda has formed the greatest productivity on all variants on a mode of irrigation. Quite high data are also noted in the variety Samur 2. Comparative analysis of variants of the experiment the total water consumption showed that, on average, for the studied varieties of cabbage most economical use observed in the irrigation regime providing for irrigation when pre-irrigation moisture threshold 75-85-75% NV. On average, the studied varieties and hybrids of cabbage, the most economical expenditure was observed in the irrigation regime, which provides for the appointment of watering at the pre-watering threshold 7585-75% NV. Compared with the first option (70-80-70% NV) saving irrigation water was 150 m3/ha, and compared with the third option (80-90-80% NV) – 178 m3/ha. On the same option was formed quite high productivity of varieties of cabbage.
