与自然授粉的对照花相比，田间豆类作物中人工花样品的自花授粉和异花授粉通常会产生更多的种子。因此，田间豆类作物的昆虫授粉往往是不够的。在大于12公顷的大面积田地中，靠近边缘的植物的种子产量大于靠近中心的植物。茎上部的节比茎下部的节产生的荚少，并且它们包含的种子也少，且种子的大小较小。
Summary Self-pollinating and cross-pollinating by hand samples of flowers in field bean crops usually gave an increased set of seed compared with control flowers left to be pollinated naturally. Hence, insect pollination of field bean crops is often inadequate. In large fields of more than 12 ha the seed yield was greater by plants near the edge than near the centre. Fewer pods were produced from nodes at the upper than the lower parts of a stem, and they contained fewer seeds which were of a smaller size.
