ÖZET Muhtelif gübre kombinasyonları ile ekim aralık ve mesafelerinin, ayçiçeğinin (H. annuus) verimi ve bazı karakterleri üzerindeki etkilerini araştırmak üzere, 1964-1965 yıllarında, Atatürk Oniversİtesi Ziraat Fakültes, Zİrai Araştırma Enstitüsü arazisinde denemeler kurulmuştur. 1964 yılında sulamanın aksaması sebebiyle, iki yıllık ortalamalara gejre, gübrelemenin verim ve muhtelif karakterler üzerindeki tesirleri istatistikselolarak ortaya konamamış, sadece azot gübrelemesinin, danenin yağ oranına menfi tesiri olduğu tesbit edilmiştir. Ekim aralık ve mesafelerinin, bitki boyu, yaprak adedi ve danenin -. ')~anı üzerinde önemli bir etkisi görülmemiştir. Buna mukabil, ortalamu- 14:LO. kalınlığı, sap ağırlığı, tabla çapı, tablanın dane tutma oranı, tabla başıncı, düsen ortalama dane sayısı, danenin iç oram ve tabla başma dane verimi gibı münferit bitkilerden elde edilen değerler üzerinde, ekim aralık ve mesafelerfifrn---<inemli etkileri tesbit edilmiştir. Gerek sıra arası ve gerekse sıra üzeri ekİm rnes:afeleri genişledikçe, yukarda verilen münferit değerler de buna paralelolarak, önemli bir şekilde artmıştır. SUMMARY EFFECT OF WITHIN-AND BETWEEN-ROW SPACINGS ON THE YIELD AND SOME AGRONOMIC CHARACTERS OF SUNFLOWER (H. annuus) UNDER THE ECOLOGICAL CONDITIONS OF ERZURUM Experiments were conducted İn 1964 and 1965 to study the effects of different fertilizer combinations with different between - andwithin-row spacings on the yield and some characters of sunflowers (H. annuus). Experimenta! fields are within the irrigation area of number 4 well at the Agricu1tural Experiment Station, Atatürk University in the West of Erzurum, Turkey. The a1titude of this area is 1900 m. on the average, and the soil is silty and silty-Ioam. Basically, it has an alluvia1 character. The sunflower variety, Yeşilköy 416 (V. 1646), was used in the experiments. The experiments were conducted in split-plot desing with four replications. The eighteen fertilizer combinations were applied to the main plots and the four spacing combinations (2 between-and 2 witlıin-row spacings) to the sub-plots within each main plot, randomly. Because of the interruption occured in the irrigation system in 1964, according to two-year averages, fertilizer effects on yield and diffierent characters of sunflower couId not be shown, but only the negative effect of N fertilization could be determined, statistically. No significant effect of spacing treatments was seen on plant hight, number of leaves, and oH percentage of the seed. But, statistical1y significant effects of between-and withinrow spacing treatments were determined, on the individual plant measurements such as average stem diameter, stem weight, head diameter, fertility pereentage of a head, average number of seeds per head, kernel pereentage of seeds, and seed yield per head. Thus, the highest values in the individual measurements mentioned above were obtained from 60x40 Cm. plantings, and the lowest ones from 50x30 cm. plantings. The values obtained from 50x40 cm. and 60x30 cm. plantings took a place between them. No significant effect of spacing treatments was observed on the seed yield per decar, according to the statistical analyses based on the real seed yield per plot. However, it was determined that the narrow plantings (50x30 cm.; 50x40 cm.) gaye more seed yield than wider plantings (60x30cm.; 60x40 cm.) according to the calculations made by taking bird and stand losses into consideration (because theyare more harmful to experimental plots as compared to field plantings).
