Application of different forms of organic matter in a pepper crop grown in soil

Abstract

The objective of this work was to compare the effects of two sources of organic matter (cotton gin compost and poultry manure) on a pepper crop (Capsicum annuum L. var. California) grown in soil. The effects of these amendments on the mineral nutrition of the pepper plant as well as on the production and mineral content of the fruit were determined. The results showed that the chemical composition of the organic matter applied to the soil had a different influence on the development of the crop, highlighting the plants amended with poultry manure, which showed higher contents of macro and micronutrients in the leaf, as well as in the fruit and higher weight. and number of peppers harvested. Possibly the higher content in poultry manure than in cotton compost of low molecular weight peptides easily assimilated by the plant, as well as the higher content of fulvic acids which are more easily degraded than humic acids and therefore provide nutrients for the plant faster are responsible for these results.
