CRESCIMENTO VEGETATIVO DA MANIÇOBA SUBMETIDA A DIFERENTES MANEJOS DE SOLO, DENSIDADES DE PLANTIO E ALTURAS DE CORTE

Abstract

The word had the aim to evaluate vegetative growing of manicoba function of two management systems, three densities and four plant cuttings. It had been used randomized blocks an sub-divided with factorial (2x3x4) with 5 repetition, being two of management systems (with/without camalhao) and 3 densities of planting (6666; 3333 and 2500 plants/ha) and to sub-parcels four heights (5, 15, 30 and 45 cm). Analyzed variable were: plant height (PLHE), broting number (BRNU), dry matter production (Kg/ha), and ratio leaf/brunch (L/B). Management system and planting density do not manicoba with medium value of 114.4 cm. BRNU increased (P<0.01) with planting cut height of 45 cm and as consequence production increasement of DM of leaves total. Ratio L/B was altered by management system, planting density, cutting height, keeping bigger than other. Among evaluated treatments, cutting height was affected vegetative growing and consequently phitomass accumulation and DM production.
