Abstract

Se estudio el efecto de la aplicacion de Acido Giberelico (GA3) a la berenjena (Solanum melongena L.) "Jira" sobre su productividad y la longitud del fruto en tres experimentos de campo. En el primer ensayo, frutos significativamente mas largos fueron obtenidos con dosis de 5 a 20 ppm, alcanzandose maxima productividad de cosecha a 5 ppm, al aplicarse en plena floracion. En el segundo experimento no se detecto diferencia significativa en rendimiento al aplicarse en plena floracion, pero los frutos tuvieron longitud significativamente mayor al aplicarse 25 ppm de GA3. En el tercer experimento, la aplicacion antes de la floracion plena no afecto significativamente la productividad o la longitud del fruto, mientras que la aplicacion despues de la floracion plena aumento el rendimiento en dos is de 5 y 10 ppm, y la longitud de 5 a 30 ppm. ----- The effect of Gibberellic Acid (GA3) application to eggplant (Solanum melongena L.) "Jira" on ltS yield and fruit length was studied in three field experiment. In the first trial, significantly longer fruits were obtained at 5 to 20 ppm, with the highest yield at 5 ppm, when applied at flowering. In the second experiment, no significant difference in yield was found with applications at flowering up to 25 ppm, finding significantly longer fruits at 25 ppm. In the third experiment, spraying at early flowering did not significantly affect either yield or fruit length, while spraying after flowering significantly increased yield at 5 and 10 ppm, and fruit length at 5 to 30 ppm.
