How are yield factors for 1 X 1 skip-row planting patterns with row widths between 30 and 40 inches that are not indicated on Tables 2 or 3 calculated (e.g., a 34 row width)?
A weighted average yield factor is calculated using the two adjoining yield factors from the applicable table (Table 2 or 3). Weight the yield factors as follows: if the row width (e.g., 34) is the mid-point for the row widths listed (e.g., 32 to 36) , use two higher (e.g., 1.19) and two lower factors (e.g., 1.06); if the row width is narrower than the mid-point of the row widths listed, use three lower factors and one higher factor; or if the row width is wider than the mid-point of the row widths listed use three higher factors and one lower factor. For example, in Concho County, TX, the adjoining yield factors for a 1 X 1 X 34″ row width skip-row planting pattern are 1.06 (32 row width) and 1.19 (36 row width). The weighted yield factor for the 34 row width would be calculated as follows: [(2 x 1.06) + (2 x 1.19)] / 4 = 1.13; for a 1 X 1 X 33″ row width skip-row planting pattern, the factor would be calculated [(3 x 1.06) + (1 x 1.19)] / 4 = 1.09; and for a 1 X 1 X 35″ row width ski
