Abstract :ÖZET : Erzurum şartlarında yapılan bu araştırmada çiftlik gübresi (0, 25,5.0 tonlda), fosfor (0, 8, 16 ve 24 kg P-fi^da) ve azot (0,8,16 ve 24 kg Nida) dozlarının yumrunun direncine etkisi incelen/niştir. Çiftlik gübresinin uygulanmadığı parsellerde yumrunun taç ve orta kısmı ile ortalama yumru direnci, çiftlik gübresi verilen parsellere göre daha fazla olmuştur. Bu etki azotun verilmediği parsellerde önemli bulunmamıştır. Yüksek fosfor dozu yumru direncini artırmıştır. Fosforun bu etkisi çiftlik gübresi verilmeyen parsellerde daha belirgin olmuştur. Azotun arttşı ile yumrunun göbek, taç ve orta kısımlarının ve kabuğun direncinde önemli oranda azalma görülmüştür. Bu azalma yumrunun göbek kısmında azotun 8 kg!da dozundan sonra önemli bulunmuştur. Gübrelemenin ortalaması olarak yumrunun göbek kısmı en yüksek dirence sahip olmuştur. Göbek &u?Rm< sırası ile laç ve orta kısımları izlemiştir. EFFECT OF MANURE AND MİNERAL FERTIL1ZER ON THE STRENGTH OF POTATO TUBERS   SUMMARY : This research was carried o ut to determine the effect of manure (0, 25 and 5.0 t/decare), and phosphorus (0, 8,16 and 24 kg P20$ldecare), and niirogen (0,8,16 and 24 kg Nide care) on the strength of tubers under Erzurum conditions. The strength ofbud and centre of tubers was higher when it was not applied manure than mamure was applied. This effect vms not significant in the plots that was not applied nitrogen. The excessively dose of phosphorus increased the strength of tubers. This effect was tnore pronounced when manure was not applied. The strength of stem, bud and centre, and skin of tubers decreased with increasing nitrogen. The decrease was signifıcant at the tuber bud when nitrogen was applied more than 8 kg Nfdecare. As an average the strength was highest at the stem of tubers which was followed by the bud and centre of tubers, respective
