Productive Performance of Tomatoes under Fertigation Management

Tomato is an important global commodity, with high socioeconomic expression in Brazil, due to consumer preference and wide availability of varieties. This work aimed to evaluate the use of solution extractors in the management of fertigation and monitoring of soil salinity, in the production of table tomato cultivars, under a protected environment. The experimental design used was in randomized blocks in a factorial scheme, with four fertigation management in the plots, and two table tomato cultivars in the subplots, repeating five times. Fruit length, fruit diameter, average fruit mass, productivity and water use efficiency were evaluated. The management of fertigation based on the replacement of the electrical conductivity of the soil solution, at levels of 10% and 25% provides tomato fruits with qualitative and quantitative characteristics similar to the conventional production system, with reduction in the consumption of fertilizers, having to cultivate nugget superior agronomic performance.
