Abstract
Defoliation significantly increased leaf production on the main stem of "Thousand- headed" kale (Brassica oleracea var. acephala, DC) and tended to stimulate branching of individual plants of individual plants. Defoliated plants which were widely spaced (21,489 plants/ha.) produced more leaves and auxiliary branches than those which were closely spaced (42,978 plants/ha.) Defoliation increased harvest index by 4.5 percent and reduced yield loss by 14 percent but tended to reduce leaf yield per hectare of widely spaced plants.
