Uso de fontes alternativas de fertilizantes na cultura do feijão

Abstract

The search for alternatives uses of fertilizer in agricultural production has utmost importance, because the increased use of fertilizers leads to higher costs to the producer. Thus, the aim of this study was to evaluate the performance of alternative fertilizers sources on productive aspects of bean crops, through the use of rock dust, manure and mineral fertilizer. The experiment was conducted inside the municipality of Mariano Moro, Lowland Village, located in the middle region of the Northwest Rio Grande and micro-Erechim. The experimental design was randomized blocks (DBC) with 7 treatments and 3 repetitions. It concludes that the use of alternative sources such as rock dust and manure may constitute a viable alternative to the use of high solubility mineral fertilizers.
