The date is one of the important agricultural crops in tropical and subtropical regions, having different stages growth up to ripening. The purpose of this study was to investigate the effects of urea and potassium sulfate spraying on the qualitative and quantitative changes of dates Zahedi cultivar in Hababouk and Kimri stages. This factorial study was designed in a complete randomized block using repeated measure technique with 3 replications. Application of urea (0, 0.5, and 1%) and potassium sulfate (0, 0.5, and 1%) were accomplished. Results elucidated that spray of 0.5 and 1% urea was significantly effective on some of the morphological traits of date fruit, reducing, non-reducing and total sugars positively. However spraying had no significant effect on fruit color and chlorophyll. In Rutab and Tamar, reducing sugars elevated significantly. Regarding obtained results, urea and potassium sulfate spraying (0.5 and 1%) caused to improve the quantitative and qualitative characteristics of date fruit Zahedi cultivar in this experimental condition. |
