Response of the Peanut (Arachis hypogaea L.) Cultivar Gregory to Interactions of Digging Date and Disease Management
Table 1
Pearson correlations for canopy defoliation, pod yield, percentages of extra large kernels (%ELK) and total sound mature kernels (%TSMK), economic value, days after peanut emergence, and heat unit accumulation in the experiment for the cultivar Gregory with the first 3 of 5 digging dates or with all 5 digging dates included. Data are pooled over 17 experiments from 2003 to 2012.
