Tuber Bulking in the Potato Crop

Studies in potato agronomy. I. The effects of variety, seed size and spacing on growth, development and yield

“…They considered (1959) that L values of about one would be sufficient to meet the demands of tuber bulking. However, the field studies of Radley, Taha & Bremner (1961) suggest that this is, in fact, unlikely. If tuber characteristics determine the rate of bulking, then, since there is no accumulation of dry matter other than in the tubers for most of the tuber growth period (Fig.…”

Some effects of seed size and spacing on the yield and grading of two maincrop potato varieties: II. Bulking rate

“…This approach led to the fitting of linear regression lines to the yield data in order to produce the bulking rate as the slope of that line. Subsequently only small differences in bulking rate have been reported between varieties (Radley, Taha & Bremner, 1961) and spacing (Bromner & Taha, 1966). As a result the bulking rate has been considered to be of minor importance in determining differences in the level of final yield, and the duration of tuber bulking has been thought much more important (Radley et al 1961).…”

“…Subsequently only small differences in bulking rate have been reported between varieties (Radley, Taha & Bremner, 1961) and spacing (Bromner & Taha, 1966). As a result the bulking rate has been considered to be of minor importance in determining differences in the level of final yield, and the duration of tuber bulking has been thought much more important (Radley et al 1961). However this division of the causes of final yield into bulking rate and the duration of bulking is not necessarily appropriate if the pattern of tuber development with time can be described by any function containing curvature such as the quadrative curve used by Carlsson (1970).…”
