Nutritional characteristics of maize cultivated with vermicompost

Abstract

This work was conducted with the objective to evaluate the effect of vermicompost application on chemical characteristics, energetic parameters and amino acids prof ile of hybrid race corn grain cultivated under open-f ield and rained conditions. The experiment was accomplished under a randomized complete design with three repetitions. Three treatments were evaluated: 1) Maize after inoculation with a commercial mycorrhizal arbuscular fungi mixture (Tec Myc 60®) plus vermicompost (V+M); vermicompost (V) and chemical fertilization (CF). Starch content in grain was 1.9% higher in V+M treatment in comparison with chemical, whereas crude protein, ether extract, crude f iber, acid detergent f iber, neutral detergent f iber, total phosphorous and phytic phosphorous were not different between treatments. Energetic parameters were not different between three treatments. 17 amino acids were evaluated of wich only tryptophan, leucine, valine, histidine and aspartic acid were higher in CF and V treatments in comparison with V+M treatment. In conclusion, it is possible to cultivate maize using vermicompost as fertilizer because chemical characteristics, energetic parameters and amino acids prof ile in maize grain were not affected compared with the maize cultivated with vermicompost added with biofertilizers (V+M) or with corn cultivated with chemical fertilizers (CF).

Effects of Vermicompost on Soil and Plant Health and Promoting Sustainable Agriculture

“…While the V + M treatment led to maize grains with 1.9% higher starch content than that achieved with CF, other components did not show significant differences. Amino acid content variations were noted between the treatments, emphasizing the importance of pre-planting VC application in influencing seed quality [53].…”

“…Moreover, ref [53] investigated the effects of applying a commercial mycorrhizal arbuscular fungi mixture (Tec Myc 60 ® ) and cow manure VC on maize grains' chemical composition, energetic parameters, and amino acid profile. The study included treatments of VC plus mycorrhizal fungi (V + M), VC alone (V), and chemical fertilization (CF).…”

Rendimiento de grano y totomoxtle bajo sistema de transición agroecológica en maíz nativo

“…En el mismo ciclo productivo O-I 2022/23, en promedio de las tres parcelas de los productores innovadores se mantiene el incremento del 27% de productividad con el manejo agroecológico respecto al manejo convencional (Figura 5). El cultivo de maíz por lo general responde bien al inocular la semilla con micorrizas y en combinación con vermicomposta, e incluso no hay cambios en otros aspectos tal como lo señalan Oliva et al, (2019), en el sentido de que es posible cultivar maíz usando vermicomposta como fertilizante porque las características químicas, los parámetros energéticos y el perfil de aminoácidos en el grano de maíz no se vieron afectados en comparación con el maíz cultivado con vermicomposta adicionada con biofertilizantes (V+M) o con el maíz cultivado con fertilizantes químicos (CF). El hecho de utilizar humus en este tipo de manejo favorece la retención de grandes cantidades de nutrientes, debido a su alta capacidad de intercambio catiónico, así también, funcionan como un estabilizador de la estructura del suelo y retienen grandes cantidades de agua (Zetina et al, 2015).…”
