Abstract
Kurak koşullarda bitki şıklığının ayçiçeğinde verim üzerine etkilerini saptamak üzere iki yıllık bir araştırma yapılmıştır (1987-1988). Bu amaçla Sunbred-262 ve H-1 hibrid çeşitleri kullanılmıştır. Dört tekerrürlü Bölünmüş Parseller Deneme Deseninde yürütülen bu çalışmada sıra arası sabit tutularak (70 cm), 10, 20, 30 ve 40 cm sıra üzeri mesafeler oluşturulmuştur (Sırasıyla, 14286, 7143, 4762 ve 3571 bitki/dekar). Denemede bitki sıklığı arttıkça tabla çapı ve 1000 tane ağırlığı azalırken düşük bitki sıklığın da bu değerler artmıştır. Bunun sonucu olarak düşük ve yeleksek bitki sıklıklarında verim değişmeyip sabit kalmıştır. Yüksek popülasyonlarda bitki boyu önemli derecede artmasına karşılık herhangi bir yatma sorunu ortaya çıkmamıştır.
In order to find out a plant population giving maximum yield, a two-year experiment was made at one location in 1987 and 1988.The experiment was conducted in a split-plot design with four replications.Two commercial hybrids, sunbred 262 and H-1, were used in this study. The space between rows was fixed in 70 cm which has been recommended largely in Turkey and four different spaces between plants were used to form different population sizes (10, 20, 30, 40 cm). The platt populations of these spaces between plants were been 142860, 71430, 47620 and 35710 plants/ha respectively. As the population size increased,head diameter and 1000-seed weight decreased and later two yield components increased under decreasing population sizes. Consequently, different sunflower populations have shown any differences in seed yield. Additionally, the final plant height increased at the highest population, but any lodging problem was not observed.
