GROWTH AND DISTRIBUTION OF FINE ROOTS OF NEEM (Azadirachta indica) UNDER TWO FARMING METHODS IN THE NORTHEAST OF BRAZIL
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 11
Abstract
Neem is an alternative for supplying firewood demand in the Brazilian semiarid, however there is few research on management for such species in the Northeast of Brazil. This study aimed to evaluate the growth and distribution of fine roots of neem under two farming methods. The experiment was conducted in a randomized complete block design with two treatments (methods A and B) and four replications, considering three depths (0–20, 20–40 and 40–60 cm) and three sampling positions (row, between the row, and diagonal). Fine root samples were collected from selected trees. The samples were washed, scanned and data length and root surfaces were obtained. Analysis of experimental data showed for both methods that fine roots were concentrated in the first 20 cm of soil. The most significant difference was in the depth of 20-40 cm, where treatment B influenced the growth and distribution of fine roots.
