??_:;-;j was the highest yielding variety across planting dates. Among the Florida
varieties FL 297 was the highest yielding and not significantly different from GA12Y. Disease (early and late leafspot and white mold) were also the lowest in GA12Y across planting dates. FL297 was significantly superior in terms of peanut quality with a higher percentage of SMK. Planting date 3 was the highest yielding across varieties and was significantly different from PD 1 and 2. Irrigation was not a significant factor for peanut yield, disease or peanut quality across varieties and PD. Despite being the highest yielding, early and late leafspot was highest in PD3. White mold was significantly higher in PDl.White mold was significantly correlated to yield (R2 = 0.49; P<0.0001). AUDPC was also significantly correlated to other kernel (R2 =0.57; 
P<0.0001) but not to yield.
