Farklı Azot Dozu Uygulamalarının Patates (Solanum tuberosum L.) Yumrusunun Mineral Madde İçeriğine Etkisi

Patates insan beslenmesinde kullanılan temel gıda ürünlerinden biridir ve patates yetiştiriciliğinde yumru kalitesini sağlamak için azot gübrelemesinin yapılış zamanı ve miktarı oldukça önemlidir. Bu araştırma, farklı azot dozlarının patateste yumru mineral madde içeriğine etkisini belirlemek amacıyla Niğde Ömer Halisdemir Üniversitesi Tarım Bilimleri ve Teknolojileri Fakültesi Araştırma ve Uygulama alanında yürütülmüştür. Materyal olarak Agria patates çeşidi ve azot kaynağı olarak üre (%46 N) gübresi kullanılmıştır. Çalışmada 6 farklı azot dozu (0, 10, 20, 30, 40, 50 kg/da) uygulanmıştır. Denemeler, Tesadüf Blokları Deneme Desenine göre 4 tekrarlamalı olarak kurulmuştur. İncelenen özelliklere ilişkin verilerle yapılan varyans analiz sonuçlarına göre, azot dozlarının yumru azot, potasyum, magnezyum, demir, çinko, mangan ve bakır içeriklerine etkisi önemli bulunmuştur. Ancak yumru fosfor, kalsiyum ve kükürt içerikleri üzerine etkisi olmamıştır. Yumrudaki en yüksek azot miktarı 50 kg/da, potasyum, magnezyum ve mangan miktarı 10 kg/da demir miktarı 20 kg/da, çinko miktarı 0 kg/da bakır miktarı 20 kg/da uygulamasından elde edilmiştir. Azot miktarının 0 kg/da’dan 50 kg/da’ a kadar artmasıyla yumrudaki azot içeriğinin arttığı bulunmuştur. Bununla beraber bu artışın bazı elementlerin miktarını belli bir seviyeye kadar arttırdığı ancak diğer mineral maddelerde ise herhangi bir etki göstermediği tespit edilmiştir.

Effect of Different Nitrogen Dose Applications on Mineral Matter Content of Potato (Solanum tuberosum L.) Tuber

Potato is one of the essential food products used in human nutrition, and the time and amount of nitrogen fertilization are very important to ensure tuber quality in potato cultivation. This research was carried out in Niğde Ömer Halisdemir University Faculty of Agricultural Sciences and Technologies Research and Application area in order to determine the effect of different nitrogen doses on the tuber mineral content of potatoes. Agria potato variety was used as material and urea fertilizer (46 % N) was used as nitrogen source. In the study, 6 different nitrogen doses (0, 10, 20, 30, 40, 50 kg/da) were applied. Plots were laid out in a randomized complete block design with four replicates. According to the results of the analysis of variance made with the data on the properties examined, the effect of nitrogen doses on the tuber nitrogen, potassium, magnesium, iron, zinc, manganese and copper contents was found to be significant. However, it had no effect on phosphorus, calcium and sulfur. The highest nitrogen content in the tuber was obtained from 50 kg/da, potassium, magnesium and manganese content 10 kg/da, iron content 20 kg/da, zinc content 0 kg/da and copper content 20 kg/da. It was found that the nitrogen content in the tuber increased with a rise in the amount of nitrogen from 0 kg/da to 50 kg/da. However, it was determined that raise increased the amount of some elements up to a certain level but did not show any effect on other mineral substances.
