Produção de tomate cereja com diferentes percentagens de matéria orgânica.

Abstract

Among vegetable species, Solanum lycopersicum is the second most produced in the world, with an effective participation in human nutrition. In turn, it is also one of the most demanding crops in fertilization. This work aims to evaluate the production of cherry tomatoes with different percentages of organic matter and compare the average number of fruits from each treatment. The experiment was carried out between June 23 and December 23, 2022, in the greenhouse of the Federal University of Campina Grande, Education and Health Center in the municipality of Cuité - Paraíba. The experimental design was entirely random, with five treatments and four repetitions, totaling 60 pots. The treatments consisted of different percentages of poultry manure, placed at the bottom of the pots in the following volumetric proportions: T1 - Control - Only soil; T2 - Soil + 5% Organic Matter (OM); T3 - Soil + 10% OM; T4 - Soil + 15% OM and T5 - Soil + 20% OM. Based on data analysis, tomato plants with organic matter showed a significant increase in the average number of fruits and production, as well as showing a medium and strong correlation between percentage of poultry manure, plant length, and number of branches, respectively. It is concluded that bird manure proved to be an efficient alternative for cultivating cherry tomatoes in pots, providing improved plant performance. It is worth noting that the percentage of 20% was the excellent limit, providing the most significant production for cherry tomatoes grown in pots.
