The effect of silicon (Si) on fitness and leaf consumption of the fall armyworm (FAW), Spodoptera frugiperda (Smith), has been observed in the laboratory, but the effects of Si on damage or defoliation reduction have not yet been determined under field conditions. Here, we evaluated the effects of amendment of soil with Si on defoliation by FAW and crop yield in maize. Two field experiments were carried out, with four doses of Si and a control (no Si amendment). Experiment #1 evaluated 150, 300, 450, and 600 kg of total Si∙ha-1, with natural or manual infestation with FAW eggs, while Experiment #2 tested 600, 800, 1,000 and 1,200 kg of total Si∙ha-1, with natural or manual infestation with FAW larvae. Defoliation reduction was observed with Si increasing in both Experiments #1 and #2. However, reduction was not observed in all evaluations, and it was dependent of infestation (natural and manual) and the time since manual infestation. Reduction in defoliation began at 600 kg Si∙ha-1. In contrast, plant Si content increased linearly with increasing soil Si application. No effect of Si application was observed on maize kernel yield. The increase in leaf Si content reduced FAW defoliation, but it did not affect maize yield from 600 to 1,200 kg∙ha-1 of Si. Amendment of soil with Si can be used as a strategy to optimize integrated pest management of FAW in maize. |

Summary: Properties of a claim loam soil, collected in Aranjuez (Madrid) and enriched with organic matter and microorganisms, were evaluated under controlled temperature and moisture conditions, over a period of three months. The following treatments were carried out: soil (control); soil + 50 t ha-1 of animal manure (E50); soil + 50 t ha-1 of animal manure + 30 L ha-1 of effective microorganisms (E50EM); soil + 30 t ha-1 of the combination of various green crop residues and weeds (RC30) and soil + 30 t ha-1 of the combination of various green crop residues and weeds + 30 L ha-1 of effective microorganisms (RC30EM). Soil samples were taken before and after incubation and their physical, chemical, and microbiological parameters analyzed. Significant increase was observed in the production of exopolysaccharides and basic phosphatase and esterase enzyme activities in the treatments E50EM and RC30EM, in correlation with the humification of organic matter, water retention at field capacity, and the cationic exchange capacity (CEC) of the same treatments. The conclusion was drawn that the incorporation of a mixture of effective microorganisms (EM) intensified the biological soil activity and improved physical and chemical soil properties, contributing to a quick humification of fresh organic matter. These findings were illustrated by the microbiological activities of exopolysaccharides and by alkaline phosphatase and esterase enzymes, which can be used as early and integrated soil health indicators. Resumo: As propriedades do solo foram avaliadas sob condições de temperatura e umidade controladas, após a incorporação da matéria orgânica e de microrganismos eficazes (EM), em um solo franco argiloso coletado sob cultivos protegidos em Aranjuéz (Madrid). Os seguintes tratamentos foram empregados: solo (controle); solo + 50 t ha-1 de esterco de animal (E50); E50 + 30 L ha-1 EM (E50EM); solo + 30 t ha-1 de restos de cultivos + plantas invasoras (RC30); RC30 + 30 L ha-1 EM (RC30EM). Amostras de solo foram retiradas após os tratamentos, antes e após a incubação e analisadas usando parâmetros físicos, químicos e microbiológicos. Os resultados mostraram um aumento significativo na produção de exopolissacarídeos, nas atividades enzimáticas de esterases e fosfatases alcalina principalmente, nos tratamentos E50EM e RC30EM, sendo diretamente correlacionadas com a humificação da matéria orgânica, com a capacidade de campo e com a capacidade de troca catiônica desses mesmos tratamentos. A partir desses resultados, pode se concluir que a qualidade do solo com a incorporação de EM potencializou a atividade biológica, contribuindo para uma mais rápida humificação da matéria orgânica fresca e melhorando a estrutura e fertilidade do solo, conforme análise das propriedades físicas e químicas, destacando-se os parâmetros microbiológicos como indicadores precoces de recuperação da qualidade do solo.
