Abstract
The objective of this work was to study the effect of different planting densities on the development and production of “Roxo de Valinhos” green figs for industry, in the Campo das Vertentes-MG region. The experiment was installed at the Risoleta Neves Experimental Field—CERN/EPAMIG. The plants used were three years old and were arranged in three randomized blocks, subject to three different planting densities, with spacings ranging from 1 m (4000 plants·ha-1), 1.5 m (2666 plants·ha-1), and 2 m (2000 plants·ha-1) between plants in the planting line and 2.5 m between row for all planting densities. The average length of the branches (m), average number of fruits per branch, average number of fruits per plant, average weight of fruits, average yield per plant and the average yield per hectare (kg) were evaluated. It was verified that, there were no significant differences in the length of branch and in the average weight of fruit, in the three densities of fig tree planting. (4000 plants·ha-1), the average number of fruits per branch (7.5), per plant (55.87) and yield per plant (878.93 kg) were lower, however. The average yield per hectare (3515.73 kg) was higher than in other growing densities. It is concluded that, the higher density of plants (4000 plants·ha-1), provides the highest productivity per area, without damages to the quality of the fruits.
Highlights
The largest fig producers in the world are Egypt and Algeria

Summary
Fruit growing is a sector of agriculture that is expanding worldwide, mainly due to the notoriety that has been given to healthier and more functional foods; the per capita fruit consumption in Brazil is of the order of 57 kg/year, index far below developed countries like Italy and Spain with 114 kg and 120 kg, respectively. This data shows how much the country needs to invest in the production of fruits in quality and quantity, besides being an extremely important activity, it moves many markets, generates large amounts in currencies and jobs [1] [2]. Rio Grande do Sul is the largest Brazilian producer, followed by Minas Gerais, both with production focused on industrialization; the state of São Paulo is the third largest producer of fig, but it is worth mentioning that it is the most important producer state of country table fig [2]
