Confirmation of causality of climatic and soil physical factors affecting the corn (<i>Zea mays</i> L.) yield for silage in the climate-soil-yield network

Abstract This study aimed to confirm the causality of climatic and soil physical factors on silage corn yield based climatesoil-yield network in Korea. The variables were growing degree days, high temperature, low surface rainfall, relative humidity, wind speed, sunshine duration before after silking. effective depth, slope drainage class soil. total digestible nutrients, dry matter fresh yields. was constructed using structural equations neural models. In result network, three causalities remarkable. First, all longitudinal silking stages significant. It implies that effect climate vegetative stage reaches through themselves reproductive stage. Second, there between indirect effects. Thus, it is likely lead an offset direct effects factors. Finally, drought heavy rainfall clear stages, respectively. indicates stress can damage for silage. Here, caused by could be recovered due various effects, while fatal because a lack path recover from. contributed identifying how affect production network. Furthermore, climate-soil-yield this will help extend structure with future studies.
