Desenvolvimento de mandioca (Manihot esculenta Crantz) em diferentes posições e corte da maniva no plantio no Sudeste do Pará

Abstract

Cassava is a root found throughout the Brazilian territory and its cultivation is carried out by the most different peoples. Nationally presents prominence in the state Pará where it is consumed culturally, despite the great importance that evidences in this state, its cultivation presents difficulties in relation to low productivity found in family farming. Thus, the objective of this study was to evaluate the development of cassava (Manihot esculenta Crantz) in different planting and cutting positions of Maniva in southeastern Pará. The work was conducted in an agricultural family establishment in the perpetual relief settlement in Nova Ipixuna – Pará. A randomized block design with four replications and six treatments was used, combining the planting position of the sprouting to the soil (vertical, horizontal and inclined) with the cut of the Maniva 9reto and bevel). We evaluated 176 plants with eight monthly assessments of height, stem diameter and number of leaves, and evaluation of production, diameter and length of roots. No differences were observed for number of leaves, stem diameter, root diameter and yield, however, presenting significance in the straight cut for height, which showed average in relation to the bevel cut. Another point that showed significance was the interaction of the position with the cut, when the inclined position was performed with the bevel cut, resulting in a lower average for root length.
