Espaçamento entre fileiras e entre plantas na produção da mandioquinha-salsa 'Branca'

Abstract

The aim of this work was to evaluate the yield, income and chemical characteristics of the different organs of 'Branca' Peruvian carrot which was cultivated in two spaces among rows of plants per plot (50 cm and 60 cm) and three spaces among plants (15, 20 and 25 cm among plants). Harvest was done 238 days after planting. Plants which were cultivated with spaces of 25 cm among plants, independent of spaces among rows, showed higher fresh (52.16 t ha-1) and dried (5.43 t ha-1) mass yield of leaves. But, on the other hand, those which were cultivated under spaces of 20 cm among plants, independent of spaces among rows, resulted in more fresh and dried mass, respectively, 0.62 t ha-1 and of 0.24 t ha-1 of shoots, 1.08 t ha-1 and 0.36 t ha-1 of crowns and 15.14 and 2.36 t ha-1 of commercial roots, in relation to yields of plants under 25 cm. From the values obtained with calculus concerning to gross income one allowed to conclude that Peruvian carrot producer can cultivate 'Branca' clone using spaces of 50 cm or 60 cm among rows in plots and 20 cm between plants in rows, what allowed producers to obtain gross income of R$ 83,940.00 or R$ 83,124.00, respectively. The highest contents of mineral residues, proteins, lipids, carbohydrates, fibers and total caloric value of plant organs indicate the possibility of using it for human consumption and for animal feeding.
