Aplicação de Solopremio® e Foliarvita® em pomar de lima ácida Tahiti

Abstract

Fruit orchards must be managed correctly, bringing good physical, chemical and biological properties in their soils to ensure longevity, system productivity and sustainability. The objective was to evaluate the influence of product Solopremio® and Foliarvita® on microbiology, soil fertility and productivity of young Tahiti acid lime orchard. The assessments were carried out in a field test, in Araras, SP, in the years 2019 and 2020. The design experimental was in randomized blocks, composed of four treatments, with four replications, totaling sixteen plots. The treatments were: T1 = application of Solopremio without straw, T2 = application of Solopremio with straw, T3 = application of Solopremio + Foliarvita with straw and T4 = control. the applications, in treatments T1 to T3, were carried out with the use of a motorized pump, in months of October (beginning of the rains), December 2019 and March 2020. The treatments cultural and phytosanitary were carried out equally in the four treatments. Were microbiology (Carbon from Biomass and Basal Respiration), analysis of soil fertility, plant productivity and fruit quality. all data were analyzed using analysis of variance and applied the comparison test of averages (Tukey, 5%). Statistical difference was observed, mainly in the second product application. In the assessment of Carbon from Microbial Biomass and Basal Respiration that occurred in a month that had heavy precipitation, accelerating the decomposition of organic matter and accentuating differences in activity microbial. In relation to soil fertility, despite statistical differences punctual, it was not possible to observe any results from the application of the products. THE productivity was higher in the treatments, with an increase of 7.7 ton ha-1 in T1, 10.53 ton ha-1 in T2 and 9.93 ton ha-1 for T3, in relation to the control. THE fruit mass was higher in the Solopremio® treatment with straw (T2) compared to to the other treatments. It is concluded that the use of Solopremio® and Foliarvita® products provides increased productivity of Tahiti acid lime.
