Estimating wheat herbage mass using a weighted disk

Estimating wheat herbage mass using a weighted disk

Animal Science Research Report Agricultural Experiment Station, Oklahoma State University ( P-951): 235-240

Disc height measurements were made for 4 cultivars of winter wheat (Triticum aestivum) during the 1993-94 wheat pasture year. Hand-clipped samples of forage were also obtained concurrently. The data were then analysed using regression analysis to determine the relationships between herbage mass and disc height. Overall relationships were poor; however, relationships for data collected during December 1993 and February 1994 had rsuperscript 2 values that ranged from 0.34 to 0.79.
