Abstract
Mixtures of soil and cotton residue compost at two different proportions were combined with five sizes of polyethylene bags to grow seedlings of Euterpe oleracea. Substrate with 50% of compost gave better results than substrates with 25% of this compost for most characters evaluated.
The greatest differences were verified for size of plastic bags.
Bags with the largest diameters (T2 = 21.5 x 21.0 cm and T5 = 21.5 x 25 cm) promoted better growth both of aerial part and root system than narrower and higher bags (T3 = 18 x 25 cm and T4 = 18 x 29.5 cm). One of the reasons for this better growth may be the higher water retention capacity verified in T2 and T5 bags.
An attack of Colletotrichum gloeosporioides Penz. (Von Arx.) occurred during the experiment.
Plants in T2 and T5 bags were healthier in comparison with plants in T3 and T4 bags.
A higher percentage of infected seedlings occurred in substrate with 50% of compost in comparison with substrate with 25% of compost.
