Kısıntılı Sulamada Şeker Mısırın Mineral Besin İçeriği

Abstract

Çalışma; 2011 ve 2012 vejetasyon döneminde taze şeker mısır Zea mays saccharata tanesinin mineral besin içeriğine kısıntılı sulamanın S S100: tam sulama;S85: % 15 kısıntı; S70: % 30 kısıntı; S55: % 45 kısıntı ve S40: % 60 kısıntı etkisini belirlemek amacıyla Isparta ekolojik koşullarında yürütülmüştür. Deneme tesadüf blokları deneme desenine göre üç tekerrürlü olarak kurulmuştur. Şeker mısır çeşidi olarak Lumina F1 kullanılmıştır. Sonuçlar kısıntılı sulamanın taze şeker mısır tanesinin mineral besin içeriğine etkisinin istatistiksel olarak önemli olduğunu göstermiştir. En yüksek azot oranı 2011’de % 2.29 ve 2012’de % 2.32 , fosfor oranı 2011’de % 0.332 ve 2012’de % 0.331 , potasyum oranı 2011’de % 0.855 ve 2012’de % 0.837 , kalsiyum oranı 2011’de % 0.031 ve 2012’de % 0.029 , magnezyum oranı 2011’de % 0.123 ve 2012’de % 0.132 , demir miktarı 2011’de 27.27 mg kg-1 ve 2012’de 26.12 mg kg-1 , bakır miktarı 2011’de 3.99 mg kg-1 ve 2012’de 4.12 mg kg-1 ve mangan miktarı 2011’de 10.92 mg kg-1 ve 2012’de 11.68 mg kg-1 “S70” sulama seviyesinden elde edilmiştir. En yüksek çinko miktarı 2011’de 34.77 mg kg-1 ve 2012’de 30.14 mg kg-1 ve bor miktarı 2011’de 5.389 mg kg-1 ve 2012’de 5.306 mg kg-1 sırasıyla I85 ve I40 sulama seviyesinde belirlenmiştir. Genellikle her iki yılda da S70 sulama seviyesine kadar su kısıtlamasıyla şeker mısırın besin içeriği artmıştır ve S70 den daha düşük sulama seviyelerde S55 ve S40 bor hariç tanenin mineral besin içeriği azalmıştır

Mineral Nutrient Content of Sweet Corn under Deficit Irrigation

Abstract

The present study was conducted to determine the effects of deficit irrigation I I100: full irrigation;I85: 15% deficit; I70: 30% deficit; I55: 45% deficitand I40: 60% deficit on mineral nutrient contents of fresh sweet corn Zea mays saccharata grain in two vegetation seasons, years of 2011 and 2012, in Isparta ecological conditions. The experiment was set up according to the Randomized Complete-Block Design with three replicates. The species of Lumina F1 was used as the sweet corn cultivar. The results revealed statistically significant effects of water deficit on mineral nutrient contents of fresh sweet corn grain. The highest nitrogen content 2.29% in 2011 and 2.32% in 2012 , the highest phosphorus content 0.332% in 2011 and 0.331% in 2012 , the highest potassium content 0.855% in 2011 and 0.837% in 2012 , the highest calcium content 0.031% in 2011 and 0.029% in 2012 , the highest magnesium content 0.123% in 2011 and 0.132% in 2012 , the highest iron amount 27.27 mg kg-1 in 2011 and 26.12 mg kg-1 in 2012 , the highest copper amount 3.99 mg kg-1 in 2011 and 4.12 mg kg-1 in 2012 and the highest manganese amount 10.92 mg kg-1 in 2011 and 11.68 mg kg-1 in 2012 were obtained from the “I70” irrigation level. The highest zinc amount 34.77 mg kg-1 in 2011 and 30.14 mg kg-1in 2012 and the highest boron amount 5.389 mg kg in 2011 and 5.306 mg kg-1 in 2012 were determined in I85 and I40irrigation levels, respectively. Generally, the mineral nutrient contents were increased with water deficit up to a certain level “I” and he lower irrigation levels I55 and I40 than “I70” resulted in decreased mineral nutrient contents, except for B, of sweet corn in both years
