Abstract

During 2018 and 2019 seasons, Sultani fig trees were sprayed three times (at growth start, just after fruit setting and at one month late) with some amino acids namely (tryptophane, methionine and cysteine) enriched with three micronutrients namely boron, zinc, iron percentages concentration 0.05 to 0.8 %. The study focused on the influence of these micronutrients on some growth and fruiting characteristics of Sultani fig cv.
Spraying Sultani fig cv. with any of these nutrients three times each at 0.05 to 0.8 % considerably enhanced all growth characters, percentages of N, P, K, Mg and Ca, yield and fruit quality in relative to the check treatment. In ascending order, spraying boron, zinc, iron and amino acids was accompanied with enhancing growth, nutritional status, yield and fruit quality.
The best results with regard to yield and fruit quality of Sultani fig cv. were obtained with spraying amino acids enriched with boron, zinc and iron three times at 0.8 %.
