本研究评估了插播甜玉米的豆类的饲料产量和质量。 1993 年和 1994 年甜玉米最后一次种植时，将五种豆类（‘Madison’毛野豌豆、‘Parabinga’桶麦草、‘Nitro’苜蓿、‘Indianhead’黑扁豆和‘Arlington’红三叶草）间种到甜玉米中。我们的目标是评估这些豆类的秋季和春季干物质产量 (DMY)、粗蛋白浓度(CPC)、粗蛋白产量 (CPY) 和体外干物质消失 (IVDMD)。玉米穗和秸秆于1993年8月31日至9月2日和1994年8月16日至17日收获。毛豌豆和苜蓿的粗蛋白浓度通常较高。两年间10月至11月粗蛋白产量均显着增加。 11 月桶装药草和毛野豌豆的 CPY 普遍较高。两年4月，越冬豆科植物（毛苕、苜蓿、红三叶草）中，CPY最高的是毛苕。除第二年试验中的毛野豌豆和红三叶草外，11 月份样本日期的平均 IVDMD 值最高。
This study evaluates the forage yield and quality of legumes interseeded into sweet corn. Five legumes ('Madison' hairy vetch, 'Parabinga' barrel medic, 'Nitro' alfalfa, 'Indianhead' black lentil, and 'Arlington' red clover) were interseeded into sweet corn at last cultivation of the sweet corn in 1993 and 1994. Our objectives were to evaluate these legumes in terms of fall and spring dry-matter yield (DMY), crude protein concentration (CPC), crude protein yield (CPY), and in vitro dry matter disappearance (IVDMD). Corn ears and stover were harvested 31 August to 2 September 1993 and 16-17 August 1994. Crude protein concentration was generally higher for hairy vetch and alfalfa. Crude protein yield significantly increased from October to November in both years. November CPY was generally higher for barrel medic and hairy vetch. In April of both years, hairy vetch had the highest CPY among the overwintering legumes (hairy vetch, alfalfa, and red clover). Except for hairy vetch and red clover in trial year 2, mean IVDMD values were highest for the November sample dates.
