Abstract

The influences of irrigation at three intervals (every 4, 6 and 8 days), potassium at three rates (24, 48 and 72 kg K2O/fad) and phosphorus at three rates (15, 30 and 45 kg P2O5/fad) on yield, yield components and seed quality of peanut cultivar Giza 5 were studied in a private farm at El-Salhya region, Sharkia Governorate during summer seasons of 2006 and 2007.
         Results show that either irrigation or fertilization treatments affected significantly all studied characters. Decreasing irrigation intervals from 8 to 6 and then to 4 days, increasing K fertilizer levels from 24 to 48 and then to 72 kg K2O/ fad and increasing P fertilizer levels from 15 to 30 and then to 45 kg P2O5/fad increased significantly plant height, number of branches/plant, number of pods/plant, seed yield/plant, 100-pod weight, shelling percentage, pod, seed and foliage yields/fad. However, oil and protein percentages significantly increased by any increase of K or P fertilizer, but with respect to irrigation treatments, the highest oil percentage was attained when the irrigation intervals were at 4 or 8 days with no significant effect on protein percentage.
        The interaction effect between irrigation intervals and K fertilizer levels on 100-pod weight and seed yield/fad as well as the interaction effect between irrigation intervals and P fertilizer levels on 100-pod weight and foliage yield/fad were significant. Irrigation every 4 days under 72 kg K2O/fad or 45 kg P2O5/fad gave the heaviest 100- pod weight and highest seed yield/fad. Foliage yield/fad were the highest with 4 days irrigation interval when 30 or 45 kg P2O5/fad were applied.
          Significant and positive correlation coefficients were detected between seed yield/fad and all studied characters, while the correlation coefficient between the same character and protein percentage was positive and insignificant.
