Abstract:

To evaluate effects of water stress and super absorbent polymer (A200) on some qualitative and quantitative traits of sunflower genotypes, a split-factorial experiment was carried out as Randomized Complete Block Design(RCBD) with three replicates on Eslamabad-e-Gharb Agricultural Research Station during 2011 and 2012.  Factors were water stress in three levels (irrigation in 25%, 50% and 75% depletion of the soil moisture) and super absorbent polymer in three levels (0, 100 and 200 kg/ha) and three sunflower genotypes (Farrokh, Ghasem and SHF81-90). In this experiment seed yield and yield components were investigated. The results showed that the highest (6337 Kg/ha) and the lowest (2601 Kg/ha) seed yield were obtained at full irrigation with SHF81-90 and full stress with Ghasem, respectively; hence, SHF81-90 at full irrigation is superior and Farrokh at water stress condition is inferior genotype. On the other hand, polymer application increased the yield and yield components on all genotypes.
