Abstract

DINIZ, Adriana Araujo et al. Liquid cattle manure and urea in soil on growth and biomass production of yellow passion fruit plants. Rev. Ciênc. Agron. [online]. 2011, vol.42, n.3, pp.597-604. ISSN 1806-6690.  https://doi.org/10.1590/S1806-66902011000300004.

This study was carried out in order to evaluate the effect of liquid cattle manure and urea on dry matter production in different parts of yellow passion fruit plants. The experiment was conducted during the period of September 2006 to December 2007, in Remígio county Paraiba State, Brazil. The experimental design was randomized blocks with three replications using the factorial squeme 5 x 2 referring to liquid cattle manure (CLM) diluted with water (W) at levels 0% (0CLM + 4W); 25% (1CLM + 3W); 50% (2CLM + 2W); 75% (3CLM + 1W) and 100% (4CLM + 0W) taking 4 L plant-1 as standard volume of each mixture in soil without and with nitrogen applied monthly from 30 days after the planting to the end of the experiment. At 420 days after planting, were obtained the stem diameter and the number of productive branches of the plants; then, the plants were collected, each plant was divided in root, stem, lateral and productive branches and was obtained the dry matter of each part of the plant. The results showed that the interaction liquid cattle manure x nitrogen exercise significant effect on stem diameter, productive branches and biomass of the root, stem, leaves, lateral and productive branches, but with statistic superiority to plants with cattle liquid manure and urea applied to the soil.
