Other claims from this paper (10)
- Intervention effect Dolomitic limestone increased shelled-pea yield by 645 pounds per acre on acid potato soils.
- Intervention effect Lime prevented premature yellowing of inoculated pea vines.
- Intervention effect Lime produced normal dark-green vine growth without nitrogen fertilizer.
- Intervention effect N or NPK raised high-quality low-tenderometer pea yield in only four of 16 trials where lime and inoculation were used.
- Intervention effect Nitrogen consistently increased vine yield.
- Intervention effect Nitrogen increased yield of lower-quality, high-tenderometer peas in most experiments.
- Intervention effect Lime tended to delay pea maturity on a common harvest date.
- Intervention effect Nitrogen tended to delay pea maturity on a common harvest date.
- Recommendation Authors conclude lime with inoculated seed is more profitable than nitrogen fertilization on acid soils.
- Recommendation Authors recommend P and K fertilizers only as insurance on low-testing soils.
