Indeterminate flowering, pod dehiscence, and seed shattering are some the most important factors that limit seed yield in some Lotus species. The objective of this study was to determine strategies to maximise Lotus tenuis seed yield by evaluating: (i) the effects of row spacing (17.5 and 35.0 cm) and seeding date (autumn 2007, autumn 2008, and spring 2008) on vegetative biomass and reproductive components, and (ii) plant defoliation at the beginning of flowering to make the time of seed ripening more uniform. Plant density was held constant at 20 plants/m2. The beginning of flowering was later in plants seeded in spring than in those seeded in autumn. Defoliation retarded peak flowering through destruction of reproductive organs. Vegetative and reproductive biomasses were not significantly different between row spacings or defoliation conditions. Vegetative biomass, seed yield, pod dehiscence, and …
