- Intervention effect Calcium treatments increased 1977 peanut yield by 360 to 1,200 kg/ha.
- Intervention effect Calcium treatments increased 1977 crop value by $343 to $889/ha.
- Observation Yield gains were lower under dry fruit maturation conditions in 1978.
- Intervention effect All calcium treatments improved kernel size grades in 1977.
- Intervention effect Early flowering calcium application gave higher productivity than earlier applications.
- Intervention effect Bagged-LP application methods did not differ in 1978.
- Intervention effect Tg Gypsum application methods did not differ in 1978.
- Intervention effect Double Bagged-LP rates did not increase productivity over low rates.
- Intervention effect Double 420-Bulk rates did not increase productivity over low rates.
- Intervention effect A single Bagged-LP application was as effective as split applications.
- Observation Germinability was at least 85% for all calcium treatments in 1977.
- Observation Tg Gypsum seed germination averaged 75% in 1978.
- Observation 420-Bulk seed germination averaged 69% in 1978.
- Observation Bagged-LP seed germination averaged 74% in 1978.
- Observation Check plots had the lowest germination in both years.
- Association Seed calcium content correlated with germinability in both years.
- Association Seed potassium content correlated negatively with germinability in 1978.
- Observation Calcium sources were generally equally effective.
- Observation Under very dry fruit maturation, 420-Bulk may be inferior, especially before early flowering.
