Estimation of yield of veld with an electronic capacitance instrument

Abstract

Readings with an electronic capacitance instrument were compared with yields from the same areas in natural veld of different heights, and from a grass-clover pasture. The regression of meter reading against oven-dry weight was determined. A highly significant regression was found in respect of the data from the grass-legume pasture and a significant regression from natural veld with a height of 2 to 6 inches. No significance was found in respect of either fresh weights or oven-dry weight of longer veld grass.
