Recirculation intervals of nutrient solution in hydroponic acclimatization of banana seedlings

ABSTRACT The objective of this study was to evaluate the technical viability using longer recirculation intervals nutrient solution than those conventionally used for acclimatization Prata-Ana banana seedlings grown under hydroponic system. experiment carried out in a greenhouse plantlet production biofactory, Cruz das Almas, Bahia, Brazil, randomized block design with four replications. use (0.75, 3.75, 5.75, 11.75, and 23.75 hours) commonly vegetables (0.25 hour) evaluated present two seasons: winter summer-autumn. effect increasing interval on plant growth more pronounced when temperature higher, during summer-autumn season. Considering period between 15 20 days after transplanting, there no frequency, showing lower frequencies or only one per day first growth. However, shorter is needed because equal higher 0.75 hour decreased both seasons. Thus, 23.75-hour 0.25-hour allows decrease energy consumption, compared whole cycle.
