Other claims from this paper (8)
- Observation Spanish and Valencia types produced commercially sized mature seed yields.
- Observation Virginia and Runner types had low yields because of growing-season limits.
- Intervention effect Closer seed spacing raised yields relative to wider spacing at early and late May plantings.
- Intervention effect Seeding rates of 180 000 to 330 000 plants per hectare gave higher pod yields than rates outside this interval.
- Intervention effect Late September digging yielded more than earlier digging or post-frost digging.
- Intervention effect Split gypsum application did not raise yields.
- Intervention effect Several herbicide treatments yielded as much as hand weeding.
- Observation Specific treatments exceeded 3000 kg/ha pod yield in both 1973 and 1974.
