Study effects of super absorbent application, saline water and irrigation management on yield and yield components of peanut (Arachis hypogaea L.)

In order to study effects of super absorbent polymer application, irrigation management and irrigation with saline water on peanut (Arachis hypogaea L.) an experiment in factorial format based on randomized complete block design (RCBD) with three replications in Astaneh Ashrafiyeh Township (north of Iran) in 2011 was conducted. The factors of experiment was consists of super absorbent polymer application with two levels (A1: control (without application) and A2: 200 kg/ha application), irrigation management with 3 levels (I1: control (dry farming condition), I2: 7 days interval irrigation and I3: 14 days interval irrigation) and irrigation with saline water with 4 levels (S1: 0, S2: 2, S3: 4 and S4: 6 ds/m concentration). Measured traits were consists of seed yield, biomass yield, pod yield, number of branches per plant and 100 seeds weight. Obtained results showed that, the effect of super absorbent application, irrigation management and irrigation with saline water on all studied traits was significant at 1% probability level. Almost, more interaction effect levels on measured traits showed significant differences. The highest seed yield in current study was obtained from 200 kg super absorbent/ha, 7 days interval irrigation and without saline water irrigation.
