    Determination of the Effect of Poultry Ash Application on Agro Morphological and Quality Properties of Potato (Solanum tuberosum L.)
    (2024) Özcan, Emre; Arslan, Yusuf; Işler, Berfin
    This study was carried out in Bolu conditions in 2021 to see the effect of poultry ash, which has the potential to be a nutrient in terms of being rich in minerals and is also a soil conditioner, on the yield and quality characteristics of potato (Solanum tuberosum L.). In the study, the conventional production method of 8 kg/da P + 20 kg/da N application was tried with six different ash amounts (0, 500, 1000, 1500, 2000 kg/da poultry ash + 20 kg/da N). According to the values obtained from the study, the highest plant height (cm), the number of main stems (pieces), the specific gravity (g) 1500 kg/da ash application, the number of tubers per plant (pieces) from farmer conditions; average tuber weight (g), french fries oil rate (%), protein rate (%), big tuber rate (%) 2000 kg/da; chips oil rate (%), small tuber rate (%), dry matter rate (%) in the control plot where there was no application; Tuber yield per decare (kg/da), medium tuber ratio (%), marketable tuber ratio (%), were obtained from 1000 kg/da poultry ash application.

    Investigation of Yield and Yield Components of Some Flax (Linum usitatissimum L.) Varieties in Ankara Ecological Conditions
    (2023) Bağci, Muhittin; Arslan, Yusuf; Yaşar, Mustafa; Işler, Berfin; Ünal, Sefa
    This study was carried out to determine the effects of some flax varieties on yield and yield components in Ankara ecological conditions in 2021. The study was established with 10 flax varieties 3 replications according to the Randomized Complete Block Design. In the study, plant height (cm), first branch height (cm), number of branches per plant (pieces), number of seeds in the capsule (seed capsule-1), 1000 seed weight (g), number of encapsulated branches per plant (pieces), oil yield (kg ha-1), protein ratio (kg ha-1) and seed yield (kg ha-1) traits were examined. As a result of the research; There were statistically significant differences at the level of 1% between varieties in terms of yield and yield components. In the study, the highest seed yield, oil yield and protein yield (1806 – 599.7 – 428.5 kg ha-1) were obtained from Clli-1412 variety.

    Study on Correlation of Agromorphologic Properties in Some Camelina (Camelina sativa (L.) CRANTZ.) Genotypes
    (Centenary University, 2022) Arslan, Yusuf; Subaşi, Ilhan; Hatipoğlu, Halil; Abrak, Servet; Işler, Berfin
    The correlation of agromorphological traits can be useful for breeders in the selection of plant genotypes. In this study, the rosette period (days), days of maturity, plant height (cm), 1000-seed weight (g), and seed yield (kg ha–1 ) characteristics of 42 different Camelina genotypes that grown in Ankara (middle Anatolia) and Şanlıurfa (southeastern Anatolia), and their correlations with each other, were investigated. The accessions showed different results depending on the location in terms of the studied characters in both locations under rainfed conditions. The results showed that the highest seed yield was obtained from the PI 311735 accession (3151.8 kg ha–1 ) in Ankara and the PI 650142 accession (3056.0 kg ha–1 ) in Şanlıurfa. While the rosette period (days), days of maturity, plant height (cm), and 1000-seed weight (g), in Ankara were between 152.3 and 132.3 days, 274 and 247 days, 103.8 and 59.5 cm, and 1.50 and 0.84 g, while there were between 108.8 and 88.8 days, 202.1 and 180.1 days, 115.4 and 59.2 cm, and 1.40 and 0.50 g, in Şanlıurfa, respectively. Results showed significant differences among the genotypes in all of the studied parameters. Correlation analysis of the genotypes in both locations on the mentioned parameters was also performed. Since climate and environment affect each agromorphological parameter differently, it was observed that a genotypic correlation independent of the climate and environment could not be explained in the Camelina sativa genotypes. © 2022, Centenary University.
