Interactive Effect of Irrigation Skipping and Salicylic Acid on Yield of Sunflower (Helianthus annuus L.)

This experiment was conducted on NS Leviathan hybrids during the summer season under semiarid region. It designed as a split plot factorial arrangement using randomized complete block design (RCBD) with three replications. The purpose of this to determine skipping irrigating effect I1, I2, and I3 salicylic acid applied S1 non-applied S0 yield at growth stages (vegetative, flowering, achene-forming stages), compared effects full irrigation I4. Complete resulted in best production, while lowest recorded by without application flowering stage. treatments were found be most effective conditions low watering. Moreover, there failure stage increasing when watering missed, vegetative achene stages. Consequently, it is concluded that avoiding limiting can lead have better seed production.
