Title

Effect of Nitrogen Fertigation on Kiwifruit Yield, Quality, and Leaf Nutreint Elements of cv. Hayward in Roudsar Region

Pages

  1-15

Abstract

 In this study, the effect of fertigation (83. 3, 124. 8, 166. 4 kg Nitrogen per hectar) and “ Pit-fertilization” on fruit yield and quality of Hayward kiwifruit was investigated. Control treatment was the common manner of fertilization by local orchardist. The results showed that Leaf mineral nutrient elements significantly changed by fertilization treatment. Fertilization with 166. 4 kg N /ha and pit-fertilization significantly increased leaf nitrogen, potassium, and calcium, but no significant difference was found between treatments for phosphorus. Furthermore, the highest nitrogen was found in pit-fertilization treatments (1. 01%). The highest fruit yield per vine was found in pitfertilization treatment (56. 8 kg/vine) and fertigation with 166. 4 kg N/ha (42. 82 kg). The mean fruit weight of all fertilization treatments was more than 90 g, which was higher than the control (85. 82g). No significant difference was found for dry matter percentage in fertilization treatments, and all were more than 17%, except the pit method treatment. Fruit firmness of fertigation treatments with 83. 3 kg N/ha and pit method was more than other treatments: with 7. 69 and 7. 35 kg/cm, respectively. Fertigation increased fruit soluble solid content (SSC) and resulted in early ripening. In addition, fertigation with 83. 3 and 124. 8 kg N/ha increased significantly fruit vitamin C. Overall, pit fertilization and fertigation with 166. 4 kg N/ha are recommendable due to increasing yield and maintaining fruit quality as well as reducing fertilizing cost and ecological problems.
