Abstract
Nitrogen management is one of the key problems in potato growing, as it affects several parameters of potato growth, including the distribution of dry matter within the plant and the N and dry matter contents of the tubers. Excess of N is as harmful as N deficiency. Therefore, it is necessary to set up a system to determine the N requirement for this plant to avoid the adverse effect of excess N applications on both the crop yield itself, and also the environment. This chapter examines the dynamics of N accumulation and distribution within the plant. An attempt has been made to use the critical plant N% vs. plant mass relationship for this crop despite the fact that tuber filling dominates the plant growth process. The data used in this chapter have been obtained in several experiments, which are summarized in Table 7.1.
