Quality Indian Neem (Azadirachta indica A. Juss.) seedlings subjected to different organic substrates, Paragominas - PA

Abstract

In Family farming methods to reuse waste from the plant crops and animal creations are little
known. The aim of this study was to evaluate the potential use of substrates consisting
of organic waste, from rural properties, in seedling production indian neem (Azadirachta indica
a. Juss.). The four treatments relating to different combinations of substrates were: treatment
1- 30% basement ground + 30% washed sand + 20% equine manure + 20% carbonized
rice straw; 2- 30% basement ground + 30% washed sand + 40% carbonized rice straw; 3- 30%
basement ground + 30% washed sand + 40% equine manure; and 4- 60% black sand + 20%
equine manure + 20% carbonized rice straw. All the organic material was extracted from rural
properties. After 90 days of seeding the T3 treatment formulated winth 30% basement
ground + 30% washed sand + 40% equine manure provided the best development as the
morphological characteristics evaluated.
