EFFECT OF IRRIGATION SYSTEMS ON RICE PRODUCTIVITY

In light of the scarcity irrigation water, extreme wastage saline soils, and dominance traditional water management methods, presented research transpired in 2020 Directorate Agriculture, ALHashimiya area, Hilla City, Iraq. The latest study aimed to investigate effects subsurface drip system (SDIS) flood (FIS), with three distances 18, 20, 22 cm on two rice (Oryza sativa L.) cultivars, i.e., ‘Tarm Hashemi’ (TH) ‘Daillman Mazandarani’ (DM). systems (SDIS FIS) significantly impacted growth productivity traits crop. SDIS ensures addition an appropriate amount plants by keeping wet root zone without wasting compared system. interaction cultivar Tarm Hashemi, SDIS, distance (DID 18 cm) resulted best performance for traits, length fresh dry weight (17.66 1.80 0.85 g, respectively). It also provided highest plant vigor index (PVI), biological, grain yield (71.15 cm, 1,747.23, 608.26 g.m-2, Cultivar Hashemi proved superior Daillman Mazandarani managing morpho-yield traits. during growing season helped increase crop Compared FIS, not only improved enhanced yield, but saved abundant nutrients.
