DOSES DE FÓSFORO NA PRODUTIVIDADE DE TOMATE INDUSTRIAL

Abstract

Tomato is one of the most demanding vegetable crops in terms of phosphorus, which is very important for Brazil, in terms of production and economic value. This work aimed to evaluate doses of phosphate fertilizer on the productivity of tomatoes intended for industry. This work was carried out at Fazenda Agriter – Agronegócios LTDA, in the agricultural year of 2023, with an experimental design in randomized blocks, with six treatments and six replications, consisting of: control, without application; 150 kg/ha of P2O5; 300 kg/ha of P2O5; 450 kg/ha of P2O5; 600 kg/ha of P2O5 and 800 kg/ha of P2O5. Productivity, green, colored and ripe fruits, ºBrix and leaf P content were evaluated. After the data were subjected to analysis of variance and comparisons of means using the SKN test at 10% probability, it was found that there was no significant difference for productivity, colored fruit, green fruit, ripe fruit and °brix, however, there was significant difference for the phosphorus content in the leaves.
