Özet
Bu araştırmada Niğde-Misli Ovası’nda yaygın olarak kullanılan hızlı çözünür azot kaynakları ile birlikte bazı yavaş çözünen azot kaynaklarının sera koşullarında patates bitkisinin yumru verimine, yumruda protein, nişasta ve nitrat kapsamına etkileri ortaya konulmaya çalışılmıştır. Azot kaynatlarının ortalaması olarak, patatesin yumru verimi en yüksek N2 dozunda olup bunu N_1, N_4, N_3 ve N_0 dozları takip ederken, protein ve nisasta kapsamı uygulanan azot dozu arttıkça yükselmistir. Azot dozlarının ortalaması olarak, en yüksek yumru verimi ASAZN, en düsük ASFJ uygulamalarından elde edilirken, yumru verimine etkileri bakımından azot kaynaklarından ASAZN, ASKKÜ, AZN. FLD birinci; FLD, KKÜ ikinci; KKÜ, ASFLD, ASN-serve üçüncü; AS, ASFJ son grubu olusturmuslardır. Gruplar arasındaki farklar istatiski olarak önemli bulunmustur (p0.05). En az yumru verimi ve protein artısı saglayan ASFJ (ASFosfojips), AS (Amonyum sülfat), ASN-serve uygulamaları en fazla nisasta artısına sebep olmustur. Yumrunun NO3 azotu kapsamı üzerine degisik azot kaynakları ve dozlarının etkisi farklı olup, en yüksek NO3 azotu AS, en az ise ASN-serve, KKÜ (Kükürtle kaplı üre), FLD (Floranid) ve daha sonra ASFJ ve AZN (Azolon) uygulanan muamelelerde saptanmıştır.
In this investigation, the effects of some slow release and conventionally used fast release nitrogen sources in the soils of Nigde-Misli plain on tuber yield, and protein, starch and NO3 contents of tubers of the potato plants grown under greenhouse conditions were determined. Effect of nitrogen levels on tuber yield, as mean of nitrogen sources were found as follows: N_2>N_1>N_4>N_3>N_0. On the other hand, increasing levels of nitrogen applied to the soil increased the protein and starch contents of the potato tubers. The highest and lowest tuber yield as mean of N levels was obtained with ASAZN and ASPG respectively. According to efficiency of nitrogen sources on tuber yield, nitrogen sources were grouped as; first group ASAZN, ASSCU, AZN, FLD; second group FLD, SCU; third group SCU, ASFLD, ASN-serve and last group AS, ASPG. Differences between the groups were is statistically significant (p<0.05). ASPG (ASPhosphogypsum), AS (Ammonium sulfate) and ASN-serve applications caused the highest increase in the starch content but the lowest increases in the tuber yield and protein contents of the tubers. Effects of various nitrogen sources and levels varied on the NO3 content of the tuber; the highest NO3 content was determined with the AS, where as the lowest NO3 contents with the ASN-serve, SCU (Sulphur coated urea), FLD (Floranid) and the ASPG and AZN (Azolon) sources.
