Response of different tomato hybrids for industrial processing (TCP 26116, CVR-8161, N-901, HM-7885 and CVR-9145) to irrigation management and planting seasons in Brazilian Savanna

The second most cultivated vegetable in the world is the tomato (Solanum lycopersicum), with Brazil being one of the countries with the largest production in the world, at 4 million tons annually. The socioeconomic importance is quite relevant on the national scene, since the state of Goiás is the largest national producer, responsible for 37% of total tomato production in 2021. The objective of this work was to evaluate the response of five tomato hybrids for industrial processing to the correct management of transparency and its influences on productivity and quality of production in two credit periods that are allowed in the state of Goiás, the 1st season: April to August (beginning of the dry season) and the 2nd season: June to September (end of the dry season). The trial was installed in an experimental arrangement in randomized blocks, in two periods, with five commercial hybrids (TCP 26116, CVR-8161, N-901, HM-7885 and CVR-9145) and four replications, totaling 20 experimental plots. Irrigation management was carried out following the recommendations of the Irrigatomate software. Soil sensors at three different depths were installed in the plots to monitor soil water content. Meteorological monitoring was carried out at the Irriplus 5000 station installed 50 meters from the experiment. The morphological characters were plant height, number of branches and number of leaves and at the end of the cycle, total productivity, commercial productivity, total soluble solids (brix degree) and savings yield were evaluated according to industry criteria. The data were tabulated with all assumptions of normality and linearity, then subjected to analysis of variance using the F test, using the SAS “Statistical Analysis System” program, with the means being compared with each other using the Tukey test, at a 5% error probability level. It was found that the five hybrids showed better responses in the first growing season. The CVR 8161 hybrid had higher total productivity, commercial productivity and higher pulp yield, in addition to the Brix degree being in the ideal range due to the proposed management. It is also concluded that the irrigation management used by the Irrigatomate software is independent of the hybrid.
