Abstract:
Volunteer, wild stands of kochia (Kochla scoparia (L.) Schrad.) were harvested at three maturity stages to determine dry matter yield and composition and to evaluate kochia as a potential forage for livestock. The plants were in the prebloom stage of growth at the first cutting, mid-bloom at the second, and full bloom at the third cutting. Dry matter yields and crude fiber levels increased and crude protein, percentage leaves, and. leaf: stem ratios decreased as stage of maturity advanced. Dry matter yields were 3,548, 8,708 and 11,327 ks/ha at the first, second and third stages, respectively. Crude protein ranged from 25.0 to 13.2%, and crude fiber from 17.9 to 37.0% of dry matter. Concentration of both macro and micro minerals either declined somewhat or remained almost constant as maturity progressed. These results suggest that kochia has high nutritive value as a forage for livestock, particularly in the earlier stages of growth.
