Competitive Effects of Sicklepod on Lima Beans

Competitive Effects of Sicklepod on Lima Beans

Sicklepod (Cassia obtusifolia L. ♯ CASOB) was planted at six densities (0 to 39.4/m2) and six durations of competition (0 to 10 weeks after seeding) in lima beans (Phaseolus lunatus L. cv. ‘Jackson Wonder’). The yield of green lima beans was inversely proportional to the density of sicklepod. In gen...

Zusammenfassung:Sicklepod (Cassia obtusifolia L. ♯ CASOB) was planted at six densities (0 to 39.4/m2) and six durations of competition (0 to 10 weeks after seeding) in lima beans (Phaseolus lunatus L. cv. ‘Jackson Wonder’). The yield of green lima beans was inversely proportional to the density of sicklepod. In general, weed densities at 2.7 to 10.8 sicklepod/m2 did not significantly reduce yields, but higher populations frequently did. The average yields generally decreased if the duration of competition exceeded six weeks.
