Research on the mainland has shown that sowing lentils in the inter-row in wheat stubble encourages the plant to grow taller in pursuit of sunlight, enabling easier harvest for what is normally a short crop. Although broad beans can be a tall crop, the bottom pods contain the largest beans as these set the earliest and thus have the longest time… read more
