Hümik Asit Uygulamalarının Patates (Solanum tuberosum L.) Bitkisinin Gelişimi ve Kalite Özellikleri Üzerine Etkileri

Bu araştırma, Konya ekolojik koşullarında bazı patates çeşitlerinin farklı miktarlardaki hümik asit uygulamalarının bitkinin gelişimi ve kalite özellikleri üzerine etkisini belirlemek amacı ile 2015 yılında Konya Toprak, Su ve Çölleşme ile Mücadele Araştırma İstasyonu Müdürlüğü deneme tarlasında yürütülmüştür. “Tesadüf Blokları Bölünmüş Deneme Deseni”ne göre üç tekerrürlü olarak kurulan bu araştırmada, üç adet farklı patates çeşidi (Agria, VR808, Brooke) ve dört farklı hümik asit dozu (0, 3, 6, 9 L da-1) kullanılmıştır. Araştırmada; dekara büyük, orta, küçük, ıskarta yumru verimleri, protein oranı, özgül ağırlık, cips verimi, cipsin yağ çekme oranı, kuru madde, nişasta oranı incelenmiştir. Dekara büyük, orta, küçük, ıskarta yumru verimlerinde artan hümik asit uygulamalarında önemli artışlar saptanmıştır. Yağ çekme oranı % 32.9-46.2, nişasta oranı % 11.7-17.3 arasında olup, hümik asit uygulamaları arasındaki farklılıklar istatistikî düzeyde önemli bulunmuştur. Cips verimi ve protein oranlarında ise uygulamalar arasında istatistikî düzeyde önem tespit edilmemiştir. İncelenen tüm parametreler göz önüne alındığında artan hümik asit uygulamalarının dekara büyük, orta, küçük ıskarta yumru verimlerini olumlu yönde etkilediği ve çeşitlerin bazı kalite özellikleri arasında da önemli varyasyonlar elde edildiği saptanmıştır.

The Effect of Humic Acid Applications on Growth and Quality Properties of Potato (Solanum tuberosum L. )

This study was carried out in Konya Soil, Water and Combating Desertification Research Station in 2015 in order to determine the effect of humic acid applications in different amounts on the development and quality properties of some potato varieties in Konya ecological conditions. Three different potato varieties (Agria, VR808, Brooke) and four different humic acid doses (0, 3, 6, 9 L da-1) were used in this study, which was established in three replications according to "The Randomized Complete Block in a Split Plot Design". In the study, large, medium, small, discarded tuber yields per decare, protein content, specific gravity, chips yield, oil holding capacity of chips, dry matter content, starch content were investigated. It was determined that there was a significant increase in humic acid applications in large, medium, small and discarded tuber yields per decare. Oil holding capacity of chips was between 32.9 % and 46.2 %, starch content was between 11.7 % and 17.3 %, and the differences between humic acid applications were found to be statistically significant for these properties. In terms of chips yield and protein content, statistical significance was not determined among the applications. Considering all the properties examined, it was determined that increasing humic acid applications positively affected the yield of large, medium and small discarded tubers per decare and significant variations were obtained among some quality properties of the varieties.
