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