Mango flowering is one of the most complex physiological processes within its development because it relates a number of factors both internal and external. Taking into account that giberelines play an important role in mango reproduction, nature seeks to promote hormonal changes, either by stimulating or inhibiting vegetative or reproductive growth, by its climatic factors, especially temperature and precipitation. The application of potassium nitrate (KNO3) stimulates the early flowering and the increase of the number of panicles in the trees that grow in tropical regions. The use of this product is not widespread in our country, so the objective of this work is to determine the effect of foliar application of potassium nitrate (KNO3) on floral induction. The experiment was carried out in plantations belonging to the Ceballos Agroindustrial Company in Ciego de Avila, for which the Super Haden variety was used in an 8m x 6m plantation frame and the treatments were divided into four blocks randomly with drip fertigation systems in a red ferralitic soil. Two foliar applications of potassium nitrate (KNO3) were carried out at a concentration of 3%. The results show that foliar application of KNO3 reaches values higher than 8.0 floral panicles per m-2, while in Control plants these values are found in 4.8, with both treatments showing significant differences.
