Identification of genotypic variation for nitrogen response in potato (Solanum tuberosum) under low nitrogen input circumstances

2009

Tiemens-Hulscher, M. | Lammerts Van Bueren, E. | Struik, P.C.

Nitrogen is an essential nutrient for crop growth. The demand for nitrogen in the potato crop is relatively high. However, in organic farming nitrogen input is rather limited, compared with conventional farming. In this research nine potato varieties were tested at three nitrogen levels. Genotypic variation for yield, leaf area index, period of maximum soil cover, sensitivity for N-shortage and nitrogen efficiency under low input circumstances was found. However, in these experiments varieties differed in their strategies to maximize tuber production under low nitrogen availability
