Abstract: Irwin mango variety gives high production under the Maracaibo´s plain agroclimatic conditions, but the fruits have some\nmalformation attributed to a physiological factor not known, there so far there is no effective treatment to prevent it or treat\nit, limits the performance of the plant. In this sense, argue the use of management techniques agronomic in order to reduce\nthe percentage of malformed fruits and produce quality fruit in optimal conditions. The study was conducted at the\nSocialist's Research Centre and Developing Fruit and Apiculture (CORPOZULIA) of Zulia state, located in the Northwest\nof the State of Zulia, characterized as very dry tropical forest. Trees were selected Irwin variety range of 11-year-old,\nplanted in a framework 10 m x 10 m. The treatments applied were: fruits thinning + KNO3 8% (T1) non fruits thinning +\nKNO3 8% (T2) non floral induction + fruits thinning (T3) and no thinning fruits, no floral induction (T4). Variables evaluated\nwere % of malformed fruits, number and weight of fruits per plant, average fruit weight, yield index and production\nefficiency and characteristics of physicochemical quality of the fruit. The results showed that fruit thinning reduced the\nnumber of malformed fruits in the variety of mango Irwin. Potassium nitrate increased fruit yield per plant and animal\nperformance, but the highest values were achieved when combined with the thinning of fruit. The fruit thinning increased\naverage fruit weight and percentage of fruit pulp and decreased the percentages of shell and seed. Thinning of fruits and\nPotassium nitrate did not greatly affect the chemical characteristics of the fruit, only degrees Brix, were affected. The results\nindicate that the practices of thinning of fruit and floral induction can improve performance and quality of fruit.
