Effect of Auxigro ph on the productivity of Natal variety melon (Cucumis melo) crop applied in two different phenological stages.
The search for alternatives that increase productivity in melon cultivation will focus on improving fruit set, fruit weight and harvest uniformity. The effect of foliar application of the mixture was evaluated: Auxigro ph® + Greenplants Zn + Greenplants B in doses of 300 g, 0.5 L and 0.25 L ha-1 respectively, in two different application intervals: 25-31 days after transplant (DAT) and 28-34 DAT. Said treatment was compared with a commercial control in the same planting lot in the Pura Vida Melons farm, located in Nicoya, Guanacaste, Costa Rica. At harvest time, ten randomized replications were evaluated, using ten linear meters as the experimental unit; The number of fruits, the number of plants, the fruits per plant, the weight per fruit and the brix degrees per fruit were counted to determine the effect of each treatment.
The application of the mixture at 28-34 DAT increased the average weight of the fruit by 100 g; In addition, the harvest was 4% more uniform, concentrating 56% of the fruit sizes in 8s, 9s and 10s, unlike the commercial treatment that concentrated 32% of its production in the aforementioned sizes. The benefit-cost ratio of the biostimulation strategy applied at 28-34 DAT is $29.28 for each dollar invested, while the application of the mixture at 25-31 DAT did not have an effect on the variables evaluated. It is concluded that the biostimulation strategy used is effective, however the moment of application is decisive to biostimulate the plant and obtain benefits in the productivity of the melon crop.
