Using Time-to-Event Model in Seed Germination Test to Evaluate Maturity during Cow Dung Composting

Maturity is a matter of concern for the utilization livestock manures after composting because phytotoxicity immature compost. The seed germination test widely used evaluating maturity However, process was not studied by establishing model maturity. Here, we established time-to-event data proportion over time in with cow dung compost at different times. Results show that profile Chinese cabbage (Brassica rapa L.) and garden cress (Lepidium sativum were both well described model. Seed delayed composts early stage from parameter t50 (half time) Parameter significantly negatively related to radicle length (RL), which indicated there an organic relationship between (i.e., emergence) elongation. In conclusion, can hinder elongation delaying germination.
