"The rate and duration of tuber growth largely determines\nthe final potato (Solanum tuberosum L) tuber\nyields. Cultivars that continue leaf development and\nnutrient uptake while maintaining maximum tuber\ngrowth rates may have higher final tuber yields, yet\ndifferent N requirements. The objective of this study\nwas to obtain information relating plant growth rates to\nN availability for selected potato cultivars. Total dry\nmatter accumulation, and N assimilation patterns of\nindeterminant cultivars, 'Russet Burbank', 'Lemhi Russet,\n'Centennial Russet', and one advanced selection\nA66107-51, were compared-with that of two determinant\ncultivars 'Pioneer' and 'Norgold Russet', at three N\nlevels. Cultivars were grown in a field experiment on a\nPortneuf silt-loam soil (Xerollic Calciorthids).\n\nHigh available soil N levels at planting delayed the\nlinear potato tuber growth period 7 to 10 days but had\nminor effects on the time of tuber initiation for the\nindeterminant varieties. Maximum tuber growth rates\n(tuber bulking) were 900 to 1,300 kg/ha/day. A66107-51\nwas superior in N-use efficiency to the other cultivars.\nBetween 70 and 100% of the total available N was utilized\nby this cultivar in producing high yields. This information\nmay be used to select lines and cultivars that will\noptimize production. A knowledge of plant growth and\nN uptake rates can improve the fertilizer recommendations\nfor each cultivar."^^ . "1981" . . "73" . . "Agronomy Journal"^^ . . . . . . . . . . . . . . "R.B."^^ .
