| Resumo: | Tomato represents an important agricultural crop, being one of the most cultivated and
consumed vegetables in Brazil and in the world. Attention is drawn to the fact that most
tomato production comes from conventional agriculture, which essentially uses practices that are harmful to the environment, such as the application of excessive amounts of chemical fertilizers. For this reason, agroecological production systems have been used as a way of mitigating the damage resulting from conventional food production, including Agroforestry Systems (SAF's). Additionally, it is necessary to explore alternative forms of fertilization adapted to tomato cultivation in SAF's. Therefore, this work aims to evaluate the development and production of cherry tomato var. Carolina when cultivated with different organic fertilizers in two SAF's. The experiment was carried out at Sítio São Clemente, located in the municipality of Macaíba/RN, in a randomized block design, with three replications, in a factorial design 2x5, consisting of two SAF's (with and without mulch) and five types of organic fertilizers. (compost, bovine manure, sheep manure, chicken manure and no fertilizer). The variables evaluated were: plant height; stem diameter, at three points: at the neck, at the average height and at the apex of the plant; number of bunches per plant; number of commercial and non-commercial fruits and total number of fruits per plant; commercial, non-commercial and total production per plant; commercial, non-commercial and total productivity; fruit mass; and diameter and length of the fruits. The collected data were submitted to analysis of variance and the means were compared by the Tukey test at 5% of probability, through the AgroEstat program. The results showed that the development and production of cherry tomato var. Carolina responded similarly to treatments with cattle
manure, sheep manure and compost, with a tendency of superiority for cattle manure; the crop had its agronomic characteristics improved by the application of mulch to the soil, and the treatment without fertilizer was the one that most responded to the litter, having its
commercial productivity doubled (2,855.3 kg.ha-1 to 5,864.7 kg.ha -1), with respect to the
SAF that did not receive mulch; some factors related to the Agroforestry System compromised tomato yield, however, they can be managed for better crop performance. |
