21 Effect of Some Cover Systems on Total and Early Season Yields of Pepper Under The Samsun Province Conditions of Turkey

Abstract

This study was conducted to determine effectiveness of some cover systems on the early season yield and total yield of pepper in the Black-Sea region of Turkey between the years 2001–2003. As experiment materials, green pepper cultivar Çetinel 150 which has being grown in the region conventionally, black, yellow and transparent polyethylene covers as well as Agryl were used. Three planting dates, black mulch and low plastic tunnel treatments were combined in different ways and experiments were designed with total 10 treatments and four replications. Growing in open field conditions which was a producer practice was tested in the experiments as a comparison treatment. As a result of the study, maximum yields regarding early, medium, late seasons (9,150-30,470-6,470 tons/ha respectively) as well as maximum total yield (46,110 Tons/ha) were obtained from April 1 planting and Agryl cover combination whereas minimum yields regarding early, medium, late seasons (4,130-19,170-3,680 tons/ha respectively) as well as minimum total yield (26,980 tons/ha) were obtained from May 1 planting which was conventional farmer treatment or comparison treatment. April 1 planting and Agryl cover combination increased the total, early, medium and late season yields 1.70, 2.21, 1.58 and 1.75 fold more comparing to May 1 planting, respectively.

Samsun İli Şartlarında Bazı Örtü Sistemlerinin Biberin Verim ve Erkenciliği Üzerine Etkisi

Abstract

Bu araştırma Karadeniz bölgesinde bazı örtü sistemlerinin biberin verim ve erkenciliğine etkisini belirlemek üzere 2001-2003 yıllarında yürütülmüştür. Denemelerde materyal olarak Karadeniz Bölgesinde yetiştirilen Çetinel 150 sivri biber çeşidi, siyah, sarı ve saydam polietilen örtü ayrıca Agryl kullanılmıştır. Çalışmada 3 dikim zamanı, siyah malç ve alçak plastik tünel uygulamaları farklı şekilde kombine edilerek 10 konulu ve 4 tekerrürlü olarak denenmiştir. Açıkta yetiştiricilik deneme konuları arasında bir mukayese kriteri olarak yer almıştır. Elde edilen sonuçlara göre erkenci, orta mevsim ve geççi verim yönünden en yüksek verimler 01 Nisan dikimi+Agryl Örtü uygulamasından elde edilirken en düşük verimler üretici uygulaması olan 1 Mayıs dikimlerinden elde edilmiştir. 01 Nisan dikimi+Agryl Örtü uygulaması 1 Mayıs dikimi uygulamasına göre toplam verimi 1.70 kat, erkenci verimi 2.21 kat, orta mevsim verimini 1.58 kat ve geççi verimi de 1.75 kat artırmıştır 1.58 kat ve geççi verimi de 1.75 kat artırmıştır.
