				<title>Abstract</title>
				<p>The influence of conservational tillage and date of digging on pod yield, crop value, and grade factors were evaluated as a means to increase the production efficiency of peanuts. Two conservational tillage systems, in-row and band tillage, and one conventional tillage system were compared over 3 yr. The Florigiant cultivar was planted in immature wheat killed with glyphosate (Roundup) or clean tilled soil. Peanuts were dug 8 to 11 d before and after the medium (normal) digging date of 141 DAP. Pod yields averaged 19&percnt; less and crop values averaged 25&percnt; less for the conservational tillage systems as compared to the conventional tillage system. Digging 8 to 11 d early reduced yield 15&percnt; and value 21&percnt;; whereas, digging 8 to 9 d late reduced yield 6&percnt; and value 5&percnt; as compared to the medium digging date. The early digging date significantly decreased the grade factors of extra-large kernels (ELK), sound mature kernels (SMK), and total meat content (TM). Tillage systems did not have a consistent effect on grade factors over the 3-yr period. Results from this study indicate that yield and value for the Florigiant cultivar were significantly less under conservational tillage as compared to conventional tillage.</p>
