Yahazu-endo

Vicia sativa, commonly known as common vetch or garden vetch, is an annual or biennial legume in the family Fabaceae native to the Mediterranean region and western Asia, now widely cultivated and naturalized across temperate regions worldwide. The species has been cultivated since ancient times as a fodder crop, green manure, and soil improver owing to its ability to fix atmospheric nitrogen through root nodule symbiosis with Rhizobium bacteria. Vicia sativa typically grows in arable fields, roadsides, disturbed ground, grasslands, and hedgerows, tolerating a wide range of soil types and climate conditions. The plant climbs by tendrils, reaching heights of 20 to 120 centimeters, and produces attractive pink-purple flowers followed by dark, hairy seed pods. Seeds contain significant protein content, making them valuable as livestock fodder, though raw seeds also contain toxic compounds that require proper preparation before human consumption. The diet of this species encompasses a wide ecological niche as a primary producer, supporting numerous herbivorous insects and other invertebrates. Vicia sativa is currently assessed as Least Concern by the IUCN, with populations widespread and stable globally. Its cultivation continues to expand in dryland farming and organic agricultural systems. Biological traits such as individual plant lifespan, weight, and precise measurements are variable and context-dependent across growing conditions.
