Occurance of recent droughts and expanding cultivation area of rain-fed fig orchards in Fars province requires the supplemental irrigation for increasing the economic productivity of fig crop cv. Sabz. Thus, the present study was conducted to improve water use efficiency of this crop. Three supplemental irrigation methods included surface, subsurface drip, and microjet were used. Control trees received no supplemental irrigation. Irrigation water volume for each tree was 1500 liters that was given to the trees in three times and equal amounts in March, May, and August. The results showed that supplemental irrigation significantly increased the yield of dried fig fruits compared to control. Microjet method increased leaf width, shoot growth length, node number, content of chlorophylls and carotenoids, and number of AA fruits (fruit diameter > 22 mm) and light yellow color fruits. Teherefore, microjet method is introduced as the superior irrigation method to improve vegetative and reproductive traits of fig cv. Sabz. |
