Influence of Organic Fertilization on Agro-morphological Traits and Mineral Nutrient Content in Bean Grains

Plant residues such as animal feed weeds and bean straws are excellent sources of raw material for the production of organic fertilizers. In view of this, the objective of this work was to evaluate the effect of organic fertilization on the agromorphological and nutritional aspects in bean grains. The experiment was implemented in the field, in a randomized block design, with three replications, in a split plot scheme, with two types of organic compound (elephant grass enriched with cattle manure) and (bean straw enriched with cattle manure) applied in six increasing doses (0.0, 33.32, 66.65, 100.00, 133.32 and 166.65%) control treatment (recommended mineral fertilization). It was possible to identify interaction between the type of compound and the doses applied only to PL. With a yield of 2.8 t ha-1, mineral fertilization did not differ from treatment with 0.0% organic fertilizer. The dose of 166.65% organic fertilizer increased grain yield reaching 3.8 t ha-1 compared to 2.4 t ha-1 obtained in the treatment with 0.0%. In addition, this treatment increased the K content in the grains. On the other hand, the application of 133.32% of organic fertilizer can be indicated for the increase in mg content in the grains.
