DIFERENTES NÍVEIS DE COMPOSTO ORGÂNICO NA FORMULAÇÃO DE SUBSTRATO PARA A PRODUÇÃO DE MUDAS DE MAMOEIRO 'FORMOSA'

Abstract

An experiment was carried out under greenhouse condition at orchard of Universidade Federal de Lavras, MG with aim studing the effect of different levels of organic matter in the seedling production of papaya Formosa. The experimental design used was of randomized blocks complet with four treatment and four replication. The treatments composited of four percentages of organic compost (0%; 10%; 20% and 40% of the total volume). Each plot 16 seedlings, one for each recipient. After 140 days of sowing, it was evaluated the following characteristics: plant height (cm), number of leaves/plant, shoot dry matter, root and total (g/plant). The presence of organic matter on substrate allawed a higher growth of papaya seedlings. The presence of40% of organic compost on the substrate was the best posibility alternative of organic matter for production of papaya seedlings.
