potassium nitrate, ammonium nitrate, floral induction, fruit quality


The flowering induction in mango (Mangifera indica L.) orchards is an agricultural practice carried out on tropical regions to obtain fruits out-of-season looking to reach better sale prices. The objective of this research was to evaluate the effect of potassium (PN), ammonium nitrate (AN) and paclobutrazol (PBZ) on flowering induction and fruit production in mango cv. Tommy Atkins. The experiment included fourteen treatments with 2, 4, and 6 % PN, and 2, 3 and 4 % AN applied in combination with PBZ (1 g of a.i. m-1 of canopy diameter), paclobutrazol alone (1 g of a.i. m-1 of canopy diameter), and a control (water), which were arranged in a completely randomized design with three replicates. Results show that floral induction and fruit production were improved: PBZ followed by foliar application PN 2 %, 4 % or 6 % induced flowering 16 days after treatments. Likewise, the major number of emerged panicles were obtained with PBZ + PN 6 %. An increase on fruit weight and size reduction was observed at harvest. PBZ followed by foliar application of nitrates induced flowering and enhanced the number developed panicles in mango cv. Tommy Atkins.


La inducción floral en mango (Mangifera indica L.) es una práctica agrícola común en regiones tropicales, tendiente a obtener frutos fuera de temporada para lograr mejores precios de la cosecha. Este trabajo tuvo como objetivo evaluar el efecto de tratamientos de nitrato de potasio (PN), nitrato de amonio (AN) y paclobutrazol (PBZ) sobre la inducción floral y producción de fruto en mango cv. Tommy Atkins. Los tratamientos con PN al 2, 4, y 6 % y AN al 2, 3 y 4 % fueron aplicados solos o combinados con PBZ (1 g de i.a. m-1 de diámetro de copa), PBZ solo y un testigo (agua) bajo un diseño completamente al azar, con tres repeticiones. Se midieron variables de inducción floral y producción de fruto. Los resultados muestran que aplicación foliar de PBZ seguida de PN (2 %), (4 %) o (6 %) indujeron floración 16 días después del tratamiento. El mayor número de panículas emergidas se obtuvieron con PBZ + PN 6 %. Se observó una reducción de peso y tamaño de fruto a la cosecha. El PBZ seguido de aplicaciones foliares con NP y AN induce floración y aumenta el número de panículas desarrolladas en mango cv. Tommy Atkins.
