Abstract
In order to investigate the effect of foliar application of humic acid, zinc sulfate and nano chelate zinc fertilizers on the quantitative and qualitative characteristics of Kamarosa strawberry cultivar, a factorial experiment was conducted in a completely randomized block design with three replications in Zahak city. Foliar application of humic acid in four concentrations of 0 (control), 200, 400 and 600 mg / l as the first factor and foliar application of zinc nanoclate (0.5, 1 and 1.5 ml/l) and zinc sulfate (1000, 2000 and 4000 mg / l) and control treatment (spraying with water) were the second factor at seven levels. The results of analysis of variance of the experimental data showed that the interactions of different levels of foliar application of humic acid and nanoclate and sulfate fertilizers on plant length, number of leaves, number of flowers, number of inflorescences, number of fruits, fruit weight, total fruit weight, length and width Fruit, chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, proteins, carbohydrates, anthocyanins, leaf phenols, fruit phenols, TSS, TA, vitamin C, nitrogen, phosphorus, potassium and zinc were significant at 1% level. Maximum plant length and number of flowers from 1.5 ml / l foliar application of zinc nanoclate and 600 mg / l humic acid spray conditions, maximum number of leaves, number of flowers and carbohydrates from 1.5 ml/l of zinc nanoclate and 400 mg / l of humic acid were obtained. Also, the highest number and weight of fruit were obtained from foliar application of 600 mg / l humic acid and 2000 mg / l zinc sulfate. The highest amount of chlorophyll a and total was obtained from foliar application of 200 mg / l humic acid and 1.5 ml / l nanoclate. The highest amount of anthocyanin was observed from foliar application of 400 mg / l humic acid and no foliar application of zinc nanoclate, the highest amount of leaf phenol was observed from foliar application of 400 mg / l humic acid and 2000 mg / l zinc sulfate. The highest amount of fruit phenol was obtained from nonfoliar application of humic acid and 2000 mg / l zinc sulfate, the highest amount of soluble solids was obtained from foliar application of 200 mg / l humic acid and 1.5 ml / l nanoclate. The highest amount of vitamin C was observed in the foliar application of 600 mg / l humic acid and 4000 mg / l zinc sulfate.
