ABSTRACT

In order to study the effect of irrigation and nitrogen fertilizer management on important physiological traits of peanut a field experiment was laid out in split plot based on randomized completely block design with three replications at Astaneh Ashrafiyeh, Guilan, Iran during 2009 growing season. Irrigation intervals were included of 6, 12 and 18 days interval (I1, I2, I3 and I4 respectively) and were allotted to main plots and nitrogen fertilizer treatments with amounts of 0, 30, 60 and 90 kg.ha-1 (abbreviated as N1, N2, N3 and N4) were allotted to sub plots. Results illustrated that the effect of irrigation management on biological yield, pod yield, crop growth rate, and pod growth rate at 1% level of probability was significant. However, its effect on pod allocation coefficient was not significant. The effect of nitrogen levels on pod yield, crop growth rate, pod growth rate and pod allocation coefficient at 1% level and on biological yield at 5% level of probability was significant. The highest values of biological yield and pod yield (6439 kg ha-1 and 4229 kg ha-1, respectively) were recorded from 6 days interval and application of 60 kg N ha-1.
