Influência da poda na qualidade nutricional das plantas e na produtividade de figo (ficus.sp) em Chapecó-SC

Abstract

Fruit growing is an activity with wide viability of development and growth in Brazil and is gradually gaining the world market. Some producers in the region, as well as a large part of the small producers in the south of the country, do not obtain knowledge of how the fig plant behaves, regarding the fruiting habit, mainly, and therefore they still resist the drastic pruning system, which is the most used system in fig culture. Due to little information about the nutritional requirements of the fig tree, the present study is necessary, which assesses the influence of pruning on the nutritional quality and productivity of two-cvs of fig tree. The experiment was conducted in the experimental area and in the Soil Chemistry and Fertility laboratory of the Federal University of Fronteira Sul, Chapecó/SC campus and in parts at EPAGRI. It was implanted in 2014, with a planting density of 5 X 2, a randomized design was used, with 3 replications, each repetition was composed of four plants in a 2x3 two-factor scheme, two cultivars Pingo de Mel and Roxo de Valinhos were used, and three numbers of branches 16, 24 and 32. The data were subjected to analysis of variance using the F test and compared using the Tukey test at the 5% level of significance. The results obtained showed that the number of productive branches did not influence the nutritional quality of the two cultivars, but that they influence the productivity of green and ripe fruits in the cultivar Pingo de Mel. The greater the number of branches, the greater the productivity. The Roxo de Valinhos cultivar, on the other hand, presents a good productive adaptation for green and ripe fruits with 16, 24 and 32 productive branches.
