Abstract

In this study, the relationships among water use efficiency (WUE), growth and yield parameters of wheat grown under irrigation conditions at 25%, 50% and 100% of available water capacity were investigated. While the amount of total irrigation water reduced from 378 mm (100% AWC) to 286 mm (50% AWC) and 249 mm (25%AWC), the plant parameter values decreased as 14,5% and 23.0% in plant height, 37,3% and 56,1% in total biomass, 31,5% and 53,3% in grain yield, respectively. While the highest WUE value for total biomass (1,49 g/L) and grain yield (0,67 g/L) was obtained with 100% AWC application, the lowest WUE value for the same parameters was found as 0,99 g/L and 0,47 g/L with 25% WUE application, respectively. Irrigation water amount gave significant positive relationships with WUE and plant growth parameters while it gave significant negative relationships with transpiration ratio and harvest index. The WUE values showed significant positive relationships with plant height, spike height, total biomass, grain yield, 1000 grain weight, and significant negative relationships with transpiration ratio, harvest index values. As a result, it was determined that soil moisture level is an important factor for plant growth, and also WUE, plant growth and yield values decrease with reducing photosynthesis rate due to decreasing soil moisture amount.

Özet

Bu çalışmada bitkiye yarayışlı su kapasitesinin %25, %50 ve %100’ündeki sulama koşullarında yetiştirilen buğday bitkisinin su kullanma randımanı (SKR), incelenen büyüme ve verim parametreleri arasındaki ilişkiler araştırılmıştır. Bitkiye uygulanan toplam sulama suyu miktarı 378 mm’den (%100 BYS) 286 mm (%50 BYS) ve 249 mm’ye (%25) düştükçe bitki boyu %14,5 ve %23.0, toplam biyokütle %37,3 ve %56,1, dane verimi %31,5 ve %53,3 oranlarında azalmıştır. Toplam biyokütle ve dane verimi için hesaplanan en yüksek SKR değerleri sırasıyla 1,49 g/L ve 0,67 g/L olarak %100 BYS da bulunurken, aynı parametreler için en düşük SKR değerleri sırasıyla 0,99 g/L ve 0,47 g/L olarak %25 BYS uygulamasında bulunmuştur. Sulama suyu miktarı, SKR ve bitki gelişim parametreleri ile önemli pozitif, transprasyon oranı ve hasat indeksiyle önemli negatif ilişki vermiştir. SKR değerleri bitki boyu, başak boyu, toplam biyokütle, dane verimi ve 1000 dane ağırlığıyla çok önemli pozitif, transprasyon oranı ve hasat indeksi değerleriyle negatif ilişkiler göstermiştir. Sonuç olarak toprak nem düzeyinin bitki gelişimi için önemli bir faktör olduğu ve aynı zamanda toprak nem miktarının azalmasıyla fotosentez oranın düşmesine bağlı olarak SKR, bitki gelişimi ve verim değerlerinin azaldığı belirlenmiştir.
