Summary
Bu araştırma, tek yıllık çimde (Lolium multiflorum L.) biçim şekli ve azot dozu uygulamalarının tohum verim öğeleri ile çimlenme özellikleri üzerine etkisini belirlemek amacıyla Tesadüf Blokları Deneme Desenine göre Eskişehir Ekolojik Koşullarında 2018 yılında yapılmıştır. Ana faktörü biçim uygulamaları (biçilen ve biçilmeyen) ve alt faktörü ise azot dozları (0, 5, 10, 15, 20 ve 25 kg/da) oluşturmuştur. Tek yıllık çimde yapılan uygulamaların tohumluk üretimine ve kalitesine etkisini belirlemek amacıyla bitki boyu, başak boyu, fertil kardeş sayısı, başakçık sayısı, bin tane ağırlığı, tohum verimi, çimlenme yüzdesi, 2. gün çimlenme yüzdesi, ortalama çimlenme süresi, fide boyu, fide yaş ve kuru ağırlığı özellikleri incelenmiştir. Sonuçlara göre, biçim uygulamasının tek yıllık çimde tohum üretimi ve kalitesine etkisi önemsiz bulunmuştur ve fertil kardeş sayısı ve bin tane ağırlığı bakımından 10-20 kg/da azot dozları arasında istatistiki olarak bir fark oluşmamıştır. En yüksek tohum verimi (120 kg/da) 10 kg/da saf N uygulamasından elde edilmiş ve bu doz sonrasında verim kayıpları oluşmuştur. Toplam çimlenme oranı azot dozlarına göre değişmezken, 2. gün çimlenme oranı ve ortalama çimlenme süresi bakımından en yüksek değerler biçilmeyen parsellere 20 kg/da N uygulaması sonucu elde edilmiştir. Sonuç olarak, tek yıllık çimde tohumluk üretimi için ekilen alanlar erken ilkbaharda biçilebilir veya otlatılabilir. Tohum üretimi için en uygun azot dozu 10 kg/da olarak belirlenmiştir. Bununla birlikte, tohumun daha hızlı çimlenme ve çıkış yapması için bu oran bir miktar arttırılabilir.

Abstract
To determine how mowing and nitrogen applications affect the seed yield components and germination characteristics of annual ryegrass (Lolium multiflorum L.), an experiment was conducted in Eskişehir Ecological Conditions in 2018 with Split-Plot in the Randomized Complete Block. The primary factor was mowing or not mowing, whereas the subfactor was nitrogen dose (0, 5, 10, 15, 20, and 25 kg/da). To determine the effect of the applications on the seed production and quality of annual ryegrass, plant height, spike length, number of fertile tillers, number of spikelets, TSW, seed yield, germination percentage, second-day germination percentage, mean germination time, seedling length, seedling fresh, and dry weight were examined. Among the results, mowing did not significantly affect the seed production and quality of annual ryegrass, and no significant difference occurred between nitrogen doses of 10–20 kg/da in terms of fertile tiller number and TSW. The highest seed yield, 120 kg/da, was obtained with 10 kg/da of nitrogen, and loss in yield was inevitable after this dose. Although total germination percentage did not change according to nitrogen dose, the highest second-day germination percentage and mean germination time were achieved in the unmowed plots with 20 kg/da of nitrogen. As a result, fields for planting annual ryegrass for seed production can be mowed or grazed in early spring. Although the best nitrogen dose for seed production was determined to be 10 kg/da, that rate can be slightly increased for earlier germination and seed emergence.
