- ... 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.

- ... Canola (Brassica napus), soybean (Glycine max), and mustard (Brassica juncea) oilseed meals were compared to three forms of synthetic N (ammonium nitrate, urea, and ammonium sulfate) in order to evaluate their relative value as sources of N for organic potato (Solanum tuberosum) production. Two trials were conducted in Maine where each oilseed meal was broadcast applied to deliver 150 lb total N p ...
