Özet
Özet Araştırma Hatay-Samandağ ilçesinde 2009-2010 yıllarında tarla şartlarında yürütülmüştür. Çalışmada amonyum sülfat gübresinin 4 farklı dozu (D0:0, D10:10, D20:20 ve D30:30 kg da-1 ) ve 5 farklı sulama düzeyinin (S100: tam sulama olup bundan daha düşük düzeydeki sulamalar S25, S50 ve S75 ile daha fazla sulama S125) maydanoz bitkilerinde nitrat, nitrit ve klorofil birikimine etkileri araştırılmıştır. Soğuk döneme denk gelen ilk hasatta (25-26 Ocak 2010) yüksek nitrat ve nitrit birikimi belirlenmiş ve gübreli uygulamalar, gübresiz uygulamaya oranla, bitki nitrat birikiminde artışa ve nitrit birikiminde azalmaya neden olmuştur. Sıcak dönemdeki (31 Mart-1 Nisan 2010) ikinci hasat, birinci hasattan oldukça düşük nitrat ve daha yüksek nitrit değerleriyle sonuçlanmıştır. Gübre dozunun artışı ile nitrat ve nitrit değerleri artmıştır. Düşük düzeydeki sulamalar her iki hasatta diğer sulama düzeylerinden daha düşük nitrat birikimine neden olmuştur. Aşırı sulama olan S125 ikinci kesimde S100’e göre nitrat ve nitrit birikimini azaltmıştır. Genellikle, klorofil değerleri her iki kesimde S25’de fazla olup, sulama düzeyindeki artış klorofilde azalma ile sonuçlanmıştır.
This study was carried out under field condition during 2009-2010 years in Hatay-Samandag. In this experiment was tested the effects of 4 nitrogen doses of ammonium sulphate (D0:0, D1:10, D2:20 and D3:30 kg da-1 N) and 5 different irrigation levels (I100: full irrigation, deficit irrigations I25, I50, I75, and excessive irrigation I125) to nitrate, nitrite and chlorophyll contents of parsley plants. High nitrate and nitrite were determined at first harvest in cold period (25-26 January 2010). Comparing to nitrogen-free treatments, nitrogen applications led to an increase to plant nitrate accumulation but a decrease to nitrite accumulation. Comparing with first harvest, second harvest in hot period (31 March-1 April 2010) was resulted with quite a few nitrate and more nitrite values. Increasing nitrogen levels had increased nitrate and nitrite values. In both harvest, small irrigation amounts caused lower nitrate accumulations as to other irrigation levels. Nitrate and nitrite contents in second harvest had decreased with excessive irrigation (I125) according to full irrigation (I100). Generally, chlorophyll values were high in S25 irrigation level in both harvest and increasing irrigation levels resulted with decreasing chlorophyll contents.
