Improve the growth and yield of figs by foliar nutrition at post-harvest

Abstract EN

A factorial experiment was carried out by spraying the fig (Ficus carica L.) trees cv.

Aswad Diyala at post-harvest in the 2014 and 2015 seasons, in one orchards of Diwaniyah city/ Iraq, with two liquid fertilizers: Azomin and Prosol at 3 levels (0, 3 and 6) g.l-1 and (0, 2 and 4) g.l-1, respectively.

The results showed that third level of both fertilizers gave The widest leaf area:{(5.53, 6.42) and (5.52 , 6.38)}m2.tree-1, highest leaf content of chlorophyll {(131.63 ,132.55) , (132.63 , 130.93)}mg.100g-1 more N percent of leaf {(2.12 , 2.11) , (2.31, 2.34)}%, highest carbohydrates percent of leaf {(14.65 , 15.10) , (14.83, 15.02)}%, for compounds and seasons, respectively.

As for the crop that took place in the 2015 and 2016 seasons gave the highest yield{(20.50, 21.66) (20.80, 21.30)}kg.tree-1, most level of K in the fruit{(280.10, 272.70), (292.40, 288.10)}mg.100g-1 and highest content of anthocyanin{(512.10, 519.90), (482.90, 494.50)} mg.100g-1.

There was a significant interaction between the experimental factors, which reached a peak in the third level, in the leaf area in the 2014 and 2015 seasons (5.85 and 6.86) m2.tree-1, and the anthocyanin in the 2015 and 2016 seasons in fruit (518.20 and 534.80) mg.100g-1, respectively.

It can be concluded that the post-harvest spraying of Aswad Diyala cv., with the, Azomin and Prosol at the levels of 6 and 4g.l-1, respectively, gave the best results.
