Pepper yield according to different types of organic fertilization

Abstract

Bell pepper (Capsicum annuum L.) is one of the most economically important vegetables in the world market, being very demanding in terms of soil fertility and, as the soils in Mozambique have, in general, low fertility, organic fertilization is used. To make them compatible with the demands of the culture. The objective of this work was to evaluate and compare the efficiency of fertilization with bovine and swine manure in terms of plant height, plant architecture, number of fruits per plant and fruit production. They were evaluated in an experiment, in the “dry” crop of 2016, at the agricultural research center of the Zambeze University in Tete-Mozambique province. The experiment was carried out in a randomized block design with three replications and plots of three rows of four meters. From each plot, fifteen plants were measured regarding plant height, number of fruits per plant and fruit production. The data were submitted to statistical processing using Sisvar software, through which normal distribution of data was confirmed, in each variable analysis of variance was performed in the Turkey multiple category test at 5% significance in consideration of the phonological indicators of the culture. The analysis of variance of all parameters evaluated, in the comparison of the averages, there were no significant differences in plant height, number of fruits per plant, and fruit production in both fertilizations, there was a significant difference in the architecture of the plant showing a higher average size when swine manure was applied. From the results shown above, we can infer that fertilization (swine manure) can be one of the alternatives when it is intended to obtain plants with erect architecture, although fruit production for both fertilization is not significant.
