Abstract

In this study conducted in 2019 in Bursa conditions, the effects of cutting irrigation water 4 (S1), 8 (S2), 12 (S3) and 16 (S4) days before harvest on tomato yield and quality were investigated in this study conducted on tomato paste Heinz-1015 variety. The experiment was carried out in 3 replications according to the randomized complete block design. The amount of seasonal irrigation water applied to the experimental treatments varied between 317 - 377 mm, the highest evapotranspiration (ET) was determined from S1 with 512 mm and the lowest ET was determined from S4 with 474 mm. The highest yield values were realized in S1 and S2 and the yield values decreased as the last irrigation was cut before harvest increased. The water productivity and irrigation water productivity values of tomatoes varied between 13.1-21.6 kg m-3 and 19.6-30.3 kg m-3, respectively, the highest values were determined in S2 and the lowest in S4 treatment. The highest Brix value in tomato fruits was measured at S4 with 6.53 and it was determined that Brix values decreased as irrigation was done close to harvest. The highest fruit hardness values were 1.13 kg and 0.99 kg from S4 and S3 treatments, respectively. L, a, b, C and h values for fruit color parameters were found to vary between 36.93-37.60, 36.37-38.40, 25.73-26.90, 44.33-46.30, 33.93-36.00, respectively. It is concluded that processing tomato is sensitive to the amount of irrigation water and time of cessation of irrigation before harvest, and if the last irrigation application is cut eight days before harvest, it leads to an improvement in quality parameters without a significant decrease in yield.

Özet

Bursa koşullarında 2019 yılında yapılan bu araştırmada, salçalık Heinz-1015 çeşidi domateste, hasattan 4 (S1), 8 (S2), 12 (S3) ve 16 (S4) gün önce sulama suyunun kesilmesinin domates verimi ve kalitesi üzerine etkileri araştırılmıştır. Deneme, tesadüf blokları deneme desenine göre 3 tekrarlamalı olarak yürütülmüştür. Deneme sonucunda, konulara uygulanan mevsimlik sulama suyu miktarı 317- 377 mm arasında değişim göstermiş, en yüksek bitki su tüketimi 512 mm ile S1 konusundan en düşük ise 475 mm ile S4 konusundan belirlenmiştir. En yüksek verim değerleri S1 ve S2 konusunda gerçekleşmiş ve son sulamanın hasattan önce kesilme süresi arttıkça verim değerleri azalmıştır. Domatesin su üretkenliği ve sulama suyu üretkenliği değerleri sırasıyla 13,1-21,6 kg m-3 ile 19.6-30.3 kg m-3 arasında değişmiş, en yüksek değerler S2 en düşük ise S4 deneme konusunda belirlenmiştir. Domates meyvelerindeki en yüksek briks değeri 6,53 ile S4 deneme konusunda ölçülmüş ve hasada yakın sulama yapıldıkça briks değerlerinin düştüğü saptanmıştır. En büyük meyve sertliği değerleri 1,13 kg ve 0,99 kg olarak sırasıyla S4 ve S3 konularından elde edilmiştir. Meyve rengi parametrelerine ilişkin L, a, b, C ve h değerlerinin sırasıyla 36.93-37.60, 36.37-38.40, 25.73-26.90, 44.33-46.30, 33.93-36.00 arasında değiştiği saptanmıştır. Salçalık domatesin sulama suyu miktarına ve hasattan önce kesilme zamanına duyarlı olduğu, son sulama uygulamasının hasattan 8 gün önce kesilmesi durumunda verimde büyük bir azalma olmaksızın kalite parametrelerinde iyileşmeye yol açtığı sonucuna varılmıştır.
