Effect of acetic acid on the pH of iron fertilizer solution (Sequestrin and Nano) and its effect on biochemical and morphological traits of strawberry (Fragaria ananassa Duch.) cv.Diamant.

With respect to the fact that the pH of the food solution has a great role in the absorption of iron element. An experiment was conducted twice plate (split plot of split plot) in the from of randomized complete block design on a strawberry plant of diamante cultivar at the researcher station of Ardebili Mohaghegh Ardabili University during the years 2015- 17. Factors included acetic acid (0, 1, 2 and %3), iron at two levels (sequestrin25gr and nano 1gr) along with two levels of agricultural soap agents (0 and % 7/5) as foliar spraying. Plant growth indices including protein, proline, resuscitation sugars, leaf starch, total phenol, leaf iron content, and yield per plant were measured. The results of analysis of variance showed that the three-way effect of treatments in all studied traits except protein and yield at the level of %1proabability on proline, resuscitation sugars, leaf starch, total phenol, leaf iron content was significant, such that the best result in the adjectives obtained from the combination of %2 steak acetic acid with iron, along with the application of %7/5 of Mooyan farming soap. and the mutual interaction of treatments at the probability level of %5 on the proten and the performance had a significant effect that which was the best results related to the combination of %2 of acetic acid with iron fertilizer without the use of Mooyan farming soap. According to the results of this study, the combination of %2 iron acetic acid composition with iron acid, along with %7/5 of the farming soap due to the reduction of leaf area tensions, improves the absorption of iron and increases the biochemical and morphological characteristics of straw berries cv.Diamant.
