The Effect of Triple tensions Drought, Salinity and Nitrogen Deficiency on Water Absorption in Tomato Plants
In order to investigate the effects of irrigation water method and water on yield, yield components and potato water productivity of Satina cultivar, a field experiment was conducted as split plots in randomized complete block design with three replications in Damavand city. The treatments consisted of Furrow irrigation (F), Drip irrigation (D), one-row irrigation (T1), Two- row irrigation (T2) and irrigation regimes including 30, 50 and 70% water requirement. Statistical analysis showed that the highest yield was obtained by irrigation (T2) with irrigation with 70% irrigation regime (average 22070 kg.ha) and the lowest yield was obtained by irrigation treatments with one-row and Furrow irrigation treatments with 30% irrigation regime respectively (16200, 16410 kg.ha).The highest productivity was obtained by two-row irrigation (T2) with irrigation regime of 30% (9.8 kg.m3) and the lowest productivity with furrow irrigation with 70% irrigation regime equal 2 kg.m3.The result showed that Two-row strip-irrigation method is recommended with a 70% irrigation regime for potato cultivation.
