Abstract:

The article discusses the modes of irrigation and mineral nutrition of carrots during growth in the Moscow region. Research objective – improvement of the planning process irrigation regimes carrots, saving water and energy resources, on the basis of improving the accuracy of the calculation methods for the measurement of water consumption given the variability in hydrometeorological conditions. According to the results of the research showed that for soddy soils of the forest zone in high-draught year is optimal irrigation regime 85-85-85 % of water holding capacity (HB) and wet year – 80-70-70 % of HB. The optimal dose of mineral fertilizers is N100P100K185. The author found that the yield of carrot is strongly influenced by low air temperature and moisture supply in the first phenological phase of development, phase in the rest of the carrot is the least demanding to hydrometeorological conditions. The experimental results showed that to implement water-saving regimes can only be based on comprehensive information about agrometeorlogical and hydrogeological conditions in specific landscapes, with obligatory consideration of the biological features of crops, variability of hydrometeorological conditions in space and time, and the nonlinear nature of the interaction of external and internal factors determining the water regime, evapotranspiration and yield of crops.
