In order to investigate the effect of super absorbent polymer on yield and some biochemical charactristics of corn under low irrigation conditions, the present experiment was conducted in split plots arrangement in a randomized complete blocks design with three replications at a field of located in Andimesh city in 2015-16 cropping year. Treatments of the experiment included low irrigation in three levels included full furrow irrigation (control), furrow irrigation in the form of a fixed one in between, furrow irrigation in the form of a variable one in between as the main factor and super absorbent polymer in three levels included non use of superabsorbent (control), 100 kilogram per hectare super absorbant and 200 kilogram per hectare super absorbent as subfactorwere considered. The results showed that low irrigation had a significant effect on grain yield, number of grain per ear, one- thousand grain weight, proline and the amount of chlorophyll a and b. Also, the use of superabsorbent significantly increased grain yield, grain yield components, the amount of chlorophyll a and b and decreased proline content. In the investigation of the effect of low irrigation and superabsorbent interaction, the number of grains per ear and grain yield were significant at one percent probability level. The highest grain yield with an average of 6.6 ton per hectare was related to full irrigation and 200 kilogram per hectare superabsorbent which was not significantly different with furrows irrigation treatment in the form of a variable one in between conditions of 100 and 200 kilogram per hectare superabsorbent by 6.1 and 6.5 ton per hectare, respectively. The lowest grain yield obtained from fixed one in between furrow irrigation under conditions of no use of superabsorbent with 4.6 ton per hectare. In general, the results showed that superabsorbent polymers have a positive and significant effect on yield parameters due to the availability of water and nutrients in two conditions of full irrigation and low irrigation. |
