Drip irrigation modes for tomatoes and table beets in the lower Volga area
Journal Title: «Таврійський науковий вісник» - Year 2017, Vol 97, Issue
Abstract
Our scientific researches of many years showed that in the light-brown soils of the Volga-Don interfluve under the climatic conditions of southern Russia we can obtain a planned yields of 40 to 120 t/ha of tomatoes and of 60 to 80 t/ha of table beets under drip irrigation. The field experiments with tomatoes were carried out under five irrigation modes and Soil Pre-Irrigation Moisture (SPIM) of 90-80, 80, 80-70 and 70-60% of Full Moisture Capacity (FMC) simultaneously with the introduction of mineral fertilizers at the rates of N70P30K35 (for a yield of 40 t/ha), N110P45K55(60 t/ha ), N150P60K75(80 t/ha), N190P75K95(100 t/ha ), N220P90K115 (120 t/ha) with five variants of plant density (20, 30. 40, 50 and 60 thousand stems / ha) under the row (interrow spacing 1.4 m) and two-line strip (0.9 + 0.5m) planting patterns. Our research on table beets was conducted under three irrigation regimes with SPIM 75, 75-85, 85% FMC and three doses of mineral fertilizers N240P150K105(60 t/ha), N280P175K123(70 t/ha),, N320P200K140(80 t/ha).
