Information × Registration Number 0221U100955, 0119U000024 , R & D reports Title To develop parameters of technological methods of cultivation of food and seed potatoes for systems of organic nutrition and protection of plants under conditions of irrigation of the Southern Steppe of Ukraine popup.stage_title Head Chernschenko Igor I., Registration Date 11-01-2021 Organization The Institute of Irriiqated Aqriculture of the NAAS Ukraine popup.description2  The highest yield of tubers - 23.85 t/ha, the potato formed against the background of green manure using the generally accepted cultivation technology. Placing it on black fallow resulted in a decrease in the yield of tubers by 1.55-4.93 t/ha, depending on the technology under study. The use of organic nutrition and plant protection in technology, especially with their combined use, led to a decrease in the yield of tubers by 1.35-6.96 t/ha. The total water consumption of potatoes averaged 4144-4326 m³/ha, from the soil layer 0.5 m, with fluctuations from year to year from 3515-3752 m3/ha in 2020 and up to 4773-4901 m3/ha in 2019. The average daily potato evaporation in the budding phase was 39.7-56.4 m3/ha, during the flowering phase this indicator reached its maximum values - 67.0-70.5 m3/ha. Moisture was used better when placing potatoes on green manure using conventional technology and biological plant protection - the water consumption coefficient was 181-188 m³/t. At the same time, 1 m³ of irrigation water contributed to the formation of 12.5-13.2 kg of tubers.
