摘要

Calcium (Ca) availability in the 0 to 8 cm soildepth often limits peanut yield and influencesgrade in the southeastern United States. Fieldexperiments were conducted in 2012 and 2013 atthe University of Georgia’s Coastal Plain ExperimentStation, Tifton, GA (CPES) and theSouthwest Georgia Research and EducationCenter, Plains, GA (SWREC) to determinelarge-seeded (Georgia-06G) and medium-seedsized (Georgia Greener) runner-type cultivarresponse to gypsum application rates of 0, 560,1120, 1650 kg/ha. Peanut pod yield and grade(TSMK) were significantly different betweenlocations with 7610 and 6540 kg/ha at CPESand SWREC, respectively. However, there wereno differences between peanut cultivars or gypsumrates. Standard germination, seed vigor (coldgermination), and seed Ca content analysis werealso conducted on subsamples from each plot.Average peanut seed germination was 97% acrossall samples. No differences were observed forstandard germination or vigor testing. Differencesin locations were observed for yield, TSMK,percent jumbo, percent medium kernels, and seedCa content. Peanut cultivar and gypsum applicationrate had effects on seed Ca concentration.Seed Ca concentration levels were 825 and 787mg/kg for Georgia Greener and Georgia-06G,respectively. Seed Ca content increased as fieldgypsum application rate increased at both locations.
