Due to the high perishability of figs, calcium stands out as an important nutrient for orchard management. This study aims to study the pre-harvest applications of calcium chloride in fig orchards. The fig trees were sprayed with 0, 0.5, 1.0, 1.5 and 2.0% CaCl₂, and fruits were thereafter stored for 0, 7, 14 and 21 d. The variables analysed were the concentration of calcium in leaves and fruits, weight loss, fruit decay, pectinolytic enzyme activity, and physical and chemical attributes of the fruits; CaCl₂ sprays enhanced fruit Ca²⁺ concentration in leaves (14.03%) and fruits (29.3%) and were effective in reducing polygalacturonase and pectin methylesterase activity, weight loss and fruit decay. Pre-treatment with 1% CaCl₂ provided fruits with larger diameters, greater firmness, and higher levels of total phenolic compounds in both fruit peel and pulp. The pre-harvest application at 1% CaCl₂ showed to be a promising technique in producing high quality fruits and extended storage by approximately 7 to 10 days. These findings may be useful in planning new cultural practices for fig orchards that produce high-quality fruit with desirable characteristics for growers and consumers.

The objective of this work was to evaluate the phenological patterns, vegetative growth, and yield characteristics of fig (Ficus carica)varieties in Southeastern Brazil. The 'Roxo de Valinhos', White Genova, PI-189, and Troyano varieties were distributed in a randomized complete block design and evaluated in the field. The following characteristics were assessed: number of days between pruning and the beginning of sprouting; leaf chlorophyll content; number of shoots on each branch; length, diameter, and number of internodes on each branch; number of leaves per plant; leaf area; number of fruit per plant; mass, length, and diameter of fruit; production and yield; and duration (days) of each phenological stage, such as thermal requirement models. 'Roxo de Valinhos' and White Genova sprouted the fastest and showed the largest number of shoots. Troyano obtained the greatest branch length and diameter, as well as the greatest number of fruit per plant, which had the shortest diameter and length and the lowest mass of fruit. Furthermore, Troyano showed the latest harvest, besides the thermal requirement of 4,577.31 degree-days. 'Roxo de Valinhos' and White Genova produced fruit with the greatest average mass and diameter and the longest length. Troyano shows better vegetative growth and produces more fruit per plant than 'Roxo de Valinhos', but both genotypes show similar yields.

Some plants do not demand a lot of chilling hours, but methods to overcome dormancy promote more vigorous and productive plant. This study aimed to assess hydrogen cyanamide and nitrogen fertilizer with different concentration to growth and production in ‘Roxo de Valinhos’ fig tree. Two crop cycles (2015/2016 and 2016/2017) was performed in São Manuel city, São Paulo State, Brazil. Phenological and productive data was evaluated in a 2 x 5 factorial (Product x Concentration), organized in randomized complete block design, with three trees by plot. The factor products had as level hydrogen cyanamide and nitrogen fertilizer and the factor concentrations was constituted by 0, 1, 2, 3, and 4%. Furthermore, the following data was evaluated: number of days for budbreak, number of buds per plant, harvest period, branch length and diameter, leaf number, leaf area, number of fruits per plant, fruit mass, production and yield. Results indicated that both products anticipated the sprouting and promoted a higher number of buds overcome the dormancy. Plant production was higher in both cycles when the products were used (2.1 and 2.7, respectively). At last, hydrogen cyanamide showed better outcomes due to the higher number of fruits and production.
