Agronomic Features of Tea
The agronomic quality of tea plants is evaluated by three indices:
bud length, hundred-bud weight, and density of buds. Data indicate
that all traits tended to increase with improved K nutrition status (Table
3). However, the use of potassium sulfate (K2SO4) did not offer any advantage
over potassium chloride (KCl). Phosphorus had a major effect
on bud length at all sites, while density of buds improved at all sites
receiving S and Mn.
