Most Hungarian winter wheat varieties need intensive plant nutrition. The optimum ranges of fertiliser application have to be calibrated by means of variety specific field trials. To choose varieties best suited to different site characteristics regarding nutrient demand, grain yield, nitrogen content and baking quality parameters, small plot experiments were conducted on two different soil types of Hungary with 4 winter wheat varieties. The nutrient treatments were planned with an economical, environmentally friendly nutrient supply in view. Four treatments were applied. Three mineral fertiliser doses ranged from a minimum NPK dose to an NPK dose exceeding the fertiliser amounts applied in national practice at present and one farm-yard manure (FYM) dose (three-year post-effect). Considerable varietal and site differences could be detected. Compared with the minimum mineral fertiliser dose, FYM treatment resulted in significantly lower grain yields at both sites. Baking quality parameters were especially unfavourable with under-fertilised treatments. In most cases, the highest mineral fertiliser dose gave the best results for the parameters tested. |
