Abstract
- The lack of yield response to the N-fertilizer strategies highlights the importanceproper timing of N-fertilizer application for potatoes which will allow reduction of N-fertilizer rate without compromising tuber yield. Two potato cultivars (Vigor and Lady Claire) were used in this study and potato tubers were collected from a potato farm in Alberta, Canada. A thorough understanding of such changes is required to optimize quality and yield potential.. A study consisting of five contrasting potato cultivars was undertaken to investigate the physiological and biochemical response of potato cultivars to N rate in terms of tuber dry matter accumulation, partitioning and quality. One method for reducing N loss to the environment is growing potatoes that require less added N. Identifying Nitrogen Use Efficient (NUE) potato varieties and characterizing their response to N stress are necessary steps to breeding for NUE in potato. Three potato-based cropping sequences, wheat-potato-wheat, canola-potato-wheat, and fababean-potato-wheat were evaluated under irrigation at the Canada-Manitoba Crop Diversification Centre at Carberry, Manitoba, Canada.
