تأثیر میزان آب مصرفی بر عملکرد و بازده مصرف آب در تولید کدوی پوست کاغذی

In order to evaluate the effect of different irrigation regimes on the yield and water use efficiency in pumpkin production experiment was conducted at the Research Farm of Bu-Ali Sina University using randomized complete block design with four treatments (3200, 4400, 6000 and 9000 m3 consumption water ha-1) and three replications. Effect of experimental treatments on all traits was significant (P<%1). Means comparison of the treatments showed that the highest number of seeds per fruit, seed weight and grain yield was obtained at 9000 m3 treatment with had no significant difference with treatment of 6000 m3 irrigation water. Also, in comparison with 9000 m3 the lowest values for these traits with reduction of 31.60, 11.69 and 53.54% was revealed at 3200 m3 irrigation water. Maximum water use efficiency was obtained at 4400 m3 irrigation water treatment with had no significant differences with treatments of 3200 and 6000 m3 irrigation water ha-1 irrigation water. So, based on the results of this research and with considering the water use efficiency, treatment of 6000 m-3 irrigation water ha-1 is suggested to production pumpkin yield.
