Bu çalışma, erken ve geç ekim zamanlarında (sonbahar yağışları öncesi ve sonrası), buğday sonrası ekilen kırmızı mercimek bitkisinin ekiminde uygulanan azaltılmış toprak işleme, doğrudan ekim ve geleneksel toprak işlemede kullanılan farklı ilaçlama yöntemlerinin yabancı ot gelişimi ve ilaç kullanım etkinliğinin belirlenmesi amacıyla yapılmıştır. Diyarbakır ilinde, 2010-2013 yılları arasında, 3 yetiştirme sezonu süresince, tesadüf bloklarında şerit parseller deneme desenine göre yürütülmüştür. Erken ve geç ekim zamanları için ayrı ayrı iki deneme kurulmuştur. Deneme, toprak işleme yöntemlerinin ilk uygulama yılındaki etkisini görmek amacıyla çakılı olmayıp, her yıl farklı bir buğday anızı üzerinde kurulmuştur. Araştırmada verim, yabancı ot yaş ağırlığı, yabancı ot kuru ağırlığı ve ilaç kullanım etkinliği parametreleri incelenmiştir. Çalışma sonucunda, buğday hasadı sonrası yetiştirilen kırmızı mercimek üretiminde, doğrudan ekimde ilk yıl yabancı ot yoğunluğu nedeniyle verim kayıpları yaşandığı, geç ekimde yabancı ot gelişiminin erken ekime göre oldukça düşük olduğu görülmüştür. Erken ekim zamanında en yüksek verim yabancı otların elle toplandığı yöntemden, geç ekim zamanında ise çıkış öncesi + çıkış sonrası ilaçlama ile yalnızca çıkış sonrası ilaçlama yöntemlerinden elde edilmiştir. Erken ekimde geleneksel, geç ekimde geleneksel ve azaltılmış toprak işleme uygulamalarından daha yüksek verim alınmıştır. Sonbahar yağışları sonrası yani geç ekimin yabancı ot yoğunluğunu azaltmada etkili olduğu ve tercih edilmesi gerektiği tespit edilmiştir. Ayrıca geç ekimde azaltılmış toprak işleme yönteminin oldukça başarılı bir şekilde uygulanabileceği görülmüştür.
This study was carried out in early and late October times (pre and after autumn rainfall), with the aim of determining the external herbal development and the effectiveness of the reduced soil processing, used in the crops of the red cabbage plant plant planted after grain, directly in the crops and the different therapeutic methods used in the traditional soil processing. In Diyarbakır province, between 2010-2013 years, during the 3 cultivation season, it was conducted according to the test pattern of strip parsels in accidental blocks. Two separate tests were established for early and late October times. The experiment was not stumbled to see the effect of soil processing methods in the first year of application, but was established on a different grain moment each year. The study studied the efficiency, foreign herbs age weight, foreign herbs dry weight and the parameters of drug use effectiveness. The study found that in the production of red grapefruit grown after grapefruit, the first year in October, due to foreign grass intensity, productivity losses occurred, and in late October, foreign grass development was quite low compared to early crops. In early October, the highest yield was obtained from the method where foreign herbs were hand-collected, and in late October, with pre-exit + post-exit therapy only from post-exit therapy methods. Early in October, more efficiency was obtained than traditional and reduced land processing practices in late in October. After autumn rains, that is, late October has been found to be effective in reducing foreign grass intensity and should be preferred. It was also shown that the reduced soil processing method in late October could be applied quite successfully.
The aim of this study was to determine the effect of weed growth and using different spraying methods on reduced soil tillage, no-tillage and conventional soil tillage in early and late sowing periods (before and after autumn rains) in red lentil sowing after wheat. The study was carried out in the randomized block strip-plot / split-block design during the 3 growing seasons between 2010 and 2013 years in Diyarbakır. Two trials were established separately for early and late sowing times. The experiment was established on a different stubble of wheat each year in order to observe the effect of soil tillage methods in the first year of application. In research, crop yield, weed wet weight, weed dry weight and spraying efficiency parameters were examined. As a result of the study, it was observed that yield losses of red lentil cultivation after wheat harvest due to weed density in direct sowing in the first year. Weed density in late sowing was found to be very low compared to early sowing. The highest yield in early sowing time was obtained from the method which weeds were collected by hand, and at late sowing time spraying before emergence+ spraying after emergence and spraying after emergence methods. Higher yields were obtained from conventional soil tillage in early sowing time; conventional soil tillage and reduced soil tillage in late sowing. After autumn rains, it is determined that late sowing is effective in reducing weed density and should be preferred. In addition, it has been seen that reduced tillage method can be applied successfully in late sowing.
