Other claims from this paper (12)
- Intervention effect Field nitrogen rates significantly increased biomass growth rate and leaf area index in all genotypes.
- Observation Nodulating genotypes reached LAI 3.0 by 60 days with at least 6 g/m2 N.
- Observation The nonnodulating M4-2 line reached LAI 3.0 at 120 days with 6 g/m2 N or 85 days with 24 g/m2 N.
- Association M4-2 vegetative and reproductive responses to rising N were positive and approximately linear.
- Intervention effect Field nitrogen fertilization did not significantly affect pod yield of nodulated genotypes.
- Intervention effect Nitrogen increased greenhouse pot pod yield.
- Intervention effect Nitrogen reduced greenhouse nodule number and weight.
- Association Genotype and N rate interacted for component yield, leaf N concentration and N content.
- Intervention effect Nitrogen generally reduced photoassimilate partitioning to pods.
- Observation Florunner fixed more nitrogen than Early Bunch.
- Observation At low fertilizer N, Florunner fixed more N than seed requirement.
- Recommendation The authors conclude nitrogen fertilization of well nodulated peanut does not increase pod or seed yield and is economically counterproductive.
