Özet
Araştırma, Doğu Akdeniz iklim koşullarında, soya bitkisinin (Bravo çeşidi) verim (dane verimi), verim parametreleri (1000 dane ağırlığı, kuru madde miktarı), vegetatif (bitki boyu, yaprak alan indeksi) ve fizyolojik özelliklerinin (stoma iletkenliği, klorofil içeriği) farklı su düzeylerine tepkisinin belirlenmesi amacıyla yürütülmüştür. Denemede 5 farklı sulama düzeyi (elverişli kapasitenin %25, %50, %75, %100 ve %125'i) esas alınmıştır. Sulamalar haftalık olarak planlanmış ve damla sulama yöntemi kullanılmıştır. Araştırma sonuçlarına göre, uygulanan sulama suyu miktarları 201.54-807.1 mm, bitki su tüketimleri 251.53 mm ile 781.71 mm, su kullanma randımanları ise 0.59-0.93 kg da-mm-1 arasında değişmiştir. Dane verimleri I25, I50, I75, I100 ve I125 sulama düzeylerinde aşılı uygulamalarda sırasıyla 218.90, 328.07, 431.80, 449.33 ve 468.27 kg da-1', aşısız uygulamalarda 198.56, 295.80, 409.10, 473.03 ve 518.73 kg da-1 olarak gerçekleşmiştir. Bitki su verim fonksiyonu (Ky) 0.63 ve 0.90 olarak hesaplanmıştır. Sulama düzeyleri tane verimi (p<0.001), 1000 dane ağırlığı (p<0.05), yağ oranı (p<0.05), protein oranı (p<0.001), çiçeklenme dönemindeki ve hasattaki kuru madde miktarlarına'na (p<0.01) etkili olurken, çiçeklenme dönemindeki bakla ve çiçek sayısına etkisi görülmemiştir. Klorofil içeriği ve stoma iletkenliği sulama mevsiminin sonuna doğru tüm uygulamalarda azalma eğilimi göstermiştir.
This research was carried out to evaluate the yield (seed yield), yield parameters (weight of 1000 seeds, dry matter accumulation), vegetative (plant weight, leaf area index) and physiological characteristics (stomatal conductance, chlorophyll content) of soybean as a response to different irrigation levels in East Mediterranean climatic conditions (Hatay Region). In the experiment, five irrigation level (as a depletion of available water content water, 25, 50, 75, 100 and 125%) were treated. Drip irrigation systems was employed and, irrigation frequency was planned as once a week troughout the irrigation season. According to results, the amount of applied irrigation water, evapotranspiration and water use efficiency ranged from 201.5-807.1 mm, 251.5-781.7 mm, 0.59-0.93 kg da-mm-1, respectively. The seed yields in inoculated and uninoculated treatments were 218.90, 328.07, 431.80, 449.33, 468.27 and 198.56, 295.80, 409.10, 473.03, 518.73 kg da-1 in I25, I50, I75, I100, I125 irrigation levels, respectively. The yield response to water (ky) was calculated as 0.63-0.90. While the amount of irrigation water were found to be influential on the seed yield (p<0.001), the weight of 1000 seeds (p<0.05), the fat (p<0.05) and protein contents (p<0.001), and dry matter content of the plant in the blooming and harvest (p<0.01), no effect on the number of pod and flowers in blooming were observed. Finally, the chlorophyll content and stomatal conductance tended to decrease in all treatments toward the end of the irrigation season.
