- ... Models provide a quantitative means to evaluate yield response of forage grasses to applied N and water availability. The objective of this analysis was to estimate model parameters (A, b, c) for bermu. dagrasses and bunchgrasses grown at the same location and during the same time period. The logistic equation was used to relate annual dry matter production to applied N for three bermudagrasses [C ...

- ... Brassica crops have potential use as a forage during summer, fall, and early winter months. The influence of planting date and harvest date on the initial and regrowth herbage yields for three Brassica species: rape (B. napus L., ‘Winfred’ in 1987 and ‘Emerald’ in 1988 and 1989), turnip (B. rapa L., ‘Purple Top’), and a turnip hybrid (B. rapa × B. pekinensis L., ‘Tyfon’) were investigated. The spe ...
