Abstract

: Bu çalışma, 2004-2005 (2 yıl) yılları arasında, Konya ekolojik koşullarında salçalık domatesin (Lycopersicon esculentum Mill cv. Shasta) toplam meyve verimi (TFY), salçalık meyve verimi (PFY), salça verimi (PO) ve bazı kalite kriterleri (ortalama meyve ağırlığı-MFW, meyve çapı-FD, meyve delinme direnci-PV, pH, toplam suda çözünebilir katı madde-TSS ve askorbik asit içeriği-AA) üzerine farklı damlatıcı aralığı ve su stresinin etkisini araştırmak amacı ile yürütülmüştür. Deneme Tesadüf Bloklarında Bölünmüş Parseller Deneme Deseni’nde ve 3 tekerrürlü olarak kurulmuştur. Lateraller her bitki sırasına bir lateral olacak şekilde yerleştirilmiştir. Denemenin ana konuları 3 farklı damlatıcı aralığı 25 cm, 50 cm ve 75 cm (A,B ve C koşulları) şeklinde oluşturulurken; alt konuları da 4 farklı sulama suyu; I1= (tam sulanan) 0-60 cm’deki eksik nemin 7 günde bir tarla kapasitesine tamamlanması, I2= %25 kısıntı, I3= %50 kısıntı ve I4= %75 olacak şekilde kısıntı konularından oluşturulmuştur. İki yıllık deneme sonuçlarına göre; her iki yılda da ana konuların en iyi toplam meyve verimi (51.8.-52.4 t ha-1) ve salçalık meyve verimi (47.2-49.3 t ha-1) A konusundan elde edilmiştir (p?0.01). Diğer taraftan, alt konularda en yüksek TFY (66.2-66.8 t ha-1), PFY (60.7-63.7 t ha-1) ve PO (11.4-12.4 t ha-1) I1 konusundan elde edilmiştir. MFW, FD ve TSS uygulamalardan etkilenmiştir (p?0.05). Yüksek stress koşullarında suda çözünebilir katı madde içeriği artmıştır. Deneme yıllarında, A konusunun sulama suyu miktarı sırasıyla 250-376 mm ve su tüketim miktarı 414-425 mm olmuştur. Alt konulardan I1 konusunun sulama suyu mikarı ise 426-587 mm iken su tüketimi 520-623 mm’dir.

Abstract

This study was carried out in order to determine the effects of different emitter spaces and water stress on total fruits yield (TFY); yield suitable for processing (PFY) and paste output (PO) of processing tomato (Lycopersicon esculentum Mill cv. Shasta) and some quality characteristics (mean fruit weight-MFW, fruit diameter-FD, penetration value of fruit-PV, pH, total soluble solids-TSS and ascorbic acid-AA contents) under ecological conditions of Konya Plain in 2004 and 2005 years. The randomized split block experimental design with three replications was applied in the study. Drip irrigation laterals were arranged in such a way that every row had one lateral. Emitter spacing of 25, 50 and 75 cm (A, B and C respectively) were the main treatments while four levels of water supply irrigation at 7 days intervals with water amount enough to fill the soil depth of 0-60 cm till field capacity (I1), and 25, 50 and 75% decreased water supply levels (I2, I3 and I4) were applied as sub treatments of the experiment. According to results of the main treatments for two years showed that the highest total fruits yield (51.75-52.43 t ha-1), as well as yield suitable for processing (47.23-49.33 t ha-1) were obtained from A treatment (p
