Abstract

Modelling is carried out for eleven major weeds in cucumber to develop estimated models for weed emergence time. Weed species were grouped according to their emergence patterns. Amaranthus retroflexus, Chenopodium album, Heliotropium europaeum, Polygonum aviculare and Solanum nigrum were early emerging, Convolvulus arvensis, Cyperus rotundus, Cynodon dactylon, Portulaca oleracea and Sorghum halepense were season long emerging Tribulus terrestris was the late emerging weed species. Different non-linear growth curves (Chapman-Richard, Weibull, logistic, Gompertz and cubic spline) fitted to the data of cumulative percent emergence for the different species and years. Cubic spline seemed the best model for many species.

Özet

İstatistiki modellerin geliştirilmesi için hıyar bitkisinde on bir önemli yabancı otun çıkış zamanın belirlenmesinde modellemeler yapılmıştır. Hıyar deneme arazisinde bulunan önemli yabancı otlar çıkış zamanlarına göre gruplara ayrılmıştır. Bu yabancı otlardan; Amaranthus retroflexus, Chenopodium album, Heliotropium europaeum, Polygonum aviculare ve Solanum nigrum erken, Convolvulus arvensis, Cyperus rotundus, Cynodon dactylon, Portulaca oleracea ve Sorghum halepense bütün vejetasyon boyunca ve Tribulus terrestris ise geç çimlenen yabancı ot türü olarak belirlenmiştir. Farklı doğrusal olmayan büyüme eğrileri (Chapman-Richard, Weibull, logistic, Gompertz ve cubic spline) farklı yabancı ot türleri ve yıllar için çıkış yüzdeleri verileri esas alınarak uyarlanmıştır. Cubic splin model birçok yabancı ot türü için en iyi model olarak saptanmıştır.
