A three-year field study was conducted to investigate the physiological growth responses, tuber yield, and processing quality of newly released chip-processing variety ‘Goun’ as affected by fertilization levels. The nitrogen (N), phosphorus (P) and potassium (K) were calculated based on soil analysis and applied as urea, fused and super phosphate, and potassium chloride, respectively. Each fertilizer was applied at planting at levels of 0, 0.5, 1.0, 1.5, and 2.0 strength of calculated basal fertilization. Potatoes were harvested 70, 80, and 90 days after planting and evaluated tuber yield, specific gravity and chip processing. The results will be discussed.
