In our study, we evaluated soybean leaf chlorophyll, yield and yield attributes change under differentwater amounts and sulphur fertilizer conditions. For this purpose; a pot experiment conducted in semi-controlledgreenhouse conditions by using three soybean varieties (Cinsoy, Arısoy and Umut-2002), four soil moisturetreatments calculated based on gravimetric method imposed from 30 days after sowing: well-watered (75% and100% field capacity) and deficit irrigation (50% and 25% field capacity) and two different sulphur doze ( 0 and 5kg/da). Plant height, the lowest pod height, filled pods plant-1, thousand-grain weight, grain yield plant-1 andSPAD chlorophyll measurements in pod development (BBCH 75) and grain filling (BBCH 85) periods wereevaluated.As a result of the study, analysis of variance showed that all parameters were significantly affected byirrigation regimes (p<0.01). While the highest average seed yield (18.6 g/plant) was observed at 100% fieldcapacity and 5 kg/da sulphur dose with Cinsoy variety in 2018, the lowest yield (3.1 g/plant) was found at 25%field capacity and 5 kg/da sulphur dose with Umut-2002 variety in 2017 growing period. SPAD chlorophyllcontent directly increased with water amount of soil and changed by variety both pod development and grainfilling periods

Bu amaçla yarı-kontrollü sera koşullarında saksı çalışması 2017 ve 2018 yıllarında üç farklı soya fasulyesi çeşidi (Cinsoy, Arısoy ve Umut-2002), gravimetrik yöntem ile belirlenen tarla kapasitesine göre hesaplanan ve ekimden 30 gün sonra uygulanan tam sulama (%75 ve %100 tarla kapasitesi) ve kısıtlı sulama (%25 ve %50 tarla kapasitesi) koşulları ile iki farklı kükürt dozu (0 ve 5 kg/da) kullanılarak yürütülmüştür. Çalışmada bitki boyu, ilk bakla yüksekliği, bitkide bakla sayısı, bin tane ağırlığı, tek bitki verimi, bakla bağlama (BBCH 75) ve tane dolum (BBCH 85) dönemlerinde SPAD klorofil ölçümleri yapılmıştır.
Sonuç olarak, sulama koşullarının incelenen tüm parametreler düzeyinde istatistiksel olarak önemli düzeyde (p<0.01) etkisi bulunmuştur. En yüksek bitki verimi (18.6 g/bitki) 2018 yılında %100 tarla kapasitesinde ve 5 kg/da kükürt dozunda Cinsoy çeşidi ile elde edilirken, en düşük verim (3.1 g/bitki) 2017 yılında %25 tarla kapasitesinde ve 5 kg/da kükürt dozunda Umut-2002 çeşidinde bulunmuştur. SPAD klorofil içeriği ise sulama miktarlarına bağlı olarak önemli düzeyde artarken, bakla bağlama ve tane dolum dönemlerinde ise çeşitlere bağlı olarak değiştiği tespit edilmiştir.
