The response of potato to different rates of nitrogen supply ranging from 0~,0 g m-2 N was studied in five field experiments near Wageningen, NL (52 ~ North). In total two late potato cultivars and two sites were used during successive seasons. The results are summarized in a set of regression equations separately for total crop and tubers. The relation between nitrogen taken up (g m -z) in the total crop and total dry matter production (g m -z) could be described with the exponential equation: 1942-1900 * 0.93x (r2=0.953, n=62). Nitrogen concentrations in tile dry matter increased linearly with nitrogen uptake. Harvest indices for dry matter and nitrogen tended to decline with increase in N uptake. Cultivars differed only in the effect of N on tuber dry matter concentration. The relation between nitrogen uptake and nitrogen supply could be fitted with quadratic regression models, but coefficients were influenced by site and season.

“…Other substances which have been implicated in tuber initiation are coumarin (Stallknecht, 1972) and ethylene (Catchpole and Hillman, 1969;Garda-Torres andGomez-Campa, 1972, 1973). Also, changes occur during the storage of tubers which favour the onset of tuberization.…”

“…In this situation sprouts grow horizontally or coil and some internodes swell and split. There can be a loss of apical dominance in the sprout system resulting in the eventual emergence of a large number of stems at each planting position, delayed tuberization and a late crop of mainly small tubers (Moorby and McGee, 1966;Catchpole and Hillman, 1975). Under some conditions the effects are greater with deep planting and compacted soil (Lapwood et at., 1967) or in the presence of Verticillium nubilum (Pitt et al, 1965).…”

In the past decade there have been several books and reviews which have considered the physiology of potatoes (Ivins and Mil thorpe, 1963;Burton, 1966;Milthorpe and Moorby, 1967;Moorby and Milthorpe, 1975). The first two of these were concerned, in part, with trying to put the study of the potato crop on a firm fundamental basis. The second two reviews reported how this work was proceeding. It seems appropriate for the purposes of this book to describe the present state of our knowledge of potato physiology and, probably more important, to discuss how our attitudes and research priorities have changed and suggest areas where we appear to need further information.Discussions such as this have usually started with the dormant tuber and subsequent development of sprouts during storage. I believe that basic physiology of sprout growth is now well understood and I intend to devote more attention to non-storage growth. The first, and major part of the chapter will be concerned, therefore, with growth in the field and the development of the crop of tubers. Physiological aspects of storage will then be considered and sprout growth discussed in terms of its management for different purposes. Growth in the field Pre-emergence growthThe potato is different from most other major annual crops in that it is usually propagated vegetatively. The seed tuber bears a number of sprouts, some or all of which may be growing. It is these growing sprouts which produce the daughter plant and the subsequent crop and, unless P. M.
