RESUMO

In the several options of fruits species with good perspectives for the organic production, it can stand out the fig (Ficus carica L.) as one of the most promising, mainly in relation to production of destined green figs the industrialization, front to possibility of aggregation of values in the final product, in the industrialization process. The objective of this work was to verify the effect of pruning time and number of productive branches on production of the âRoxo de Valinhosâ by production of green figs, in the subtropical region, under organic culture. The experiment using four year-old plants, with spacing 3 x 2 m, in Quatro Pontes-PR (24Â35â42â South latitude and 53Â59â54â West longitude, altitude of 472 m and Cfa Koppen climate, with annual maximum medium temperature of 28.5ÂC and minimum of 16.6ÂC). They settled two experiments, with the design utilized was randomized blocks with four blocks and three plants of parcel, and the first related the pruning time: April, May, June, July, August and September; and second related the number of productive branches: 6, 9, 12, 15, 18, 21 and 24. The referring data the phenology of the plants, as well as of the vegetative development and cropping cycles of 2007/2008 were collected. There were yield differences between pruning times; the July and August pruned plants presented higher yields, among the December to February months, with production pick in January. The highest green fig yield (2,949.55 g for plant) and dear productivity (4,916.9 kg for ha) was observed in the treatment which had plants conducted with 18 and 21 productive branches
