Effects of Crop Rotation on Potato Production in the Temperate Zones : Proceedings of the International Conference on Effects of Crop Rotation on Potato Production in the Temperate Zones, Held August 14–19, 1988, Wageningen, The Netherlands

This volume contains the Proceedings of the International Conference on Effects of Crop Rotation on Potato Production in the Temperate Zones. This conference was held in the International Agricultural Centre at Wageningen, The Netherlands, August 14 - 19, 1988, under the auspices of the European Association for Potato Research (EAPR), the Potato Association of America (PAA) and the Dutch National Council for Agricultural Research (NRLO). The length of rotations affect the performance of potato crops and yields are often reduced if rotations are too short. The kinds of crops within a rotation will also affect potato performance, especially those grown in the previous season. It was a major aim of the conference to bring together specialists of various disciplines to examine these determinants of potato yield. The Organizing Committee is glad that all relevant aspects of the theme are highlighted in these proceedings. The contents of the contributions are primarily left to the responsibility of the authors. J. Vos C.D. van Loon G.J. Bollen ORGANIZATION OF THE CONFERENCE The European Association for Potato Research (EAPR) and the Potato Association of America (PAA) nominated representatives in the Conference Committee. PAA was represented by prof. dr E.E. Ewing (Ithaca, USA) and by dr R.E. Thornton (Pullman, USA); EAPR was represented by prof. dr J.C. Holmes (Edinburgh, UK), ir C.D. van Loon (Lelystad, NL), and dr ir J. Vos (chairman; Wageningen, NL).
