Processing of specific growth of various potato varieties under drip irrigation in Lower Volga region

Abstract

The analysis of the state of the potato industry in the Lower Volga region is made. The heat and moisture supply and soil conditions of the region and their compliance with the biological characteristics of potato plants are estimated. The object of research is the planting of potatoes of promising varieties under drip irrigation. The aim of the research is the formation of water regimes of the soil and production processes of various varieties of potatoes during drip irrigation in years with different weather conditions for vegetation periods. The patterns of irrigation, water consumption and productivity of summer plantings of seed potatoes are established. The most productive studied variety is Zhuravinka of the Belarusian selection, planting of which forms the tuber yield from 36.07 to 43.10 t/ha, Roko of the Dutch selection with a yield of 32.86–41.13 t/ha and Golubizna of domestic selection with that of 33.06–39.81 t/ha of tubers.
