Resumo
In recent years there was an increase in the diversification of vegetable crops,
especially for cultivation in greenhouses and organic fertilizers. The tomato sets one of the
most vegetables produced in the world, and its use is justified because it is a food that has
great use in industrial and semi-processed products. The use of waste poultry as a source of
organic matter into fertilizer, prevents it from becoming a pollutant if handled improperly.
To join the inorganic formulas are in organomineral fertilizers, which increase the
efficiency of mineral fertilizers, providing reduced spending on fertilizers and promoting
the improvement in soil quality. The use of organomineral fertilizer is one of the strategies
that provide greater crop yield and better quality. In this context, the aim of this work was
to evaluate the efficiency of this granulated organomineral fertilizer enriched with
monoammonium phosphate (MAP) in the processing tomato crop. When using the
organomineral fertilizer compared to mineral fertilizer, there was a fresh mass increase of
fruit, number of fruits per plant and yield. When analyzing the chlorophyll content the
growing season proved to be the most appropriate to evaluate your changes in tomato
leaves. But at conditions studied, the organomineral fertilizer presented agronomic
performance similar to mineral fertilizer. In economic terms is justified the use of this
fertilizer for having a lower cost than mineral fertilizers.
