Análise de crescimento e produtividade da hortaliça não convencional Major Gomes (Talinum paniculatum)

Abstract

The species major gomes Talinun paniculatum is considered in conventional cultivation systems, a weed for several agricultural crops. However, this species of plant is of great importance in human nutrition, where its leaves can be used as a source of food, as it is rich in proteins and nutrients. In this sense, the objective of this research was to evaluate the growth and productivity of the aerial part of the species major gomes cultivated with different population densities in the field and to evaluate the effect of organic fertilization on production under potted cultivation conditions. The research was carried out in the experimental area of Campus III of the Center for Human, Social and Agricultural Sciences (CCHSA UFPB), in the municipality of Bananeiras- PB. In the field experiment, a randomized block experimental design was used, consisting of 5 treatments and 4 replications, totaling 20 plots. The treatments were formed by five plant population densities: 3, 4, 5, 6 and 7 plants per linear meter with row spacing of 0.3 m. In pots, a completely randomized experimental design was used with 6 replications. The treatments were composed of five doses of tanned cattle manure that corresponded to 0, 10, 20, 30, 40 t ha-1. The greater population density of major gomes plants, with the planting of up to 7 plants per linear meter provides greater production of fresh and dry leaf matter, fresh and dry stem matter and total fresh and dry matter of the aerial part. When evaluating the fresh weight as a function of fertilization, the highest production was with the dose of 40 t ha-1. Density planting reduces the diameter of the stem of plants of the major gomes species and does not affect the number of leaves produced per plant. Low doses of fertilization with cattle manure decrease the yield of fresh material and high doses of manure increase the yield of fresh material.
