    Effects of Row Spacing on Yield and Quality of Forage Pea (Pisum sativum ssp. arvense)
    (Turkish journal of range and forage science (Online), 2022) Karadeniz, Erdal; Bengisu, Gülşah
    Peas are globally used as forage, haylage, silage or straw in ruminants’ diet. Winter forage pea is also becoming an important forage crop, particularly for haylage production in Türkiye. Row spacing produce different spatial arrangements that influence competition for resources, especially radiation, in forage pea production. The aim of this study is to determine the appropriate row spacing for forage peas depending on hay yield and quality. Field experiments were performed Kızıltepe district, Mardin province of Türkiye during winter growing seasons of 2018-2019 and 2019-2020. Özkaynak pea variety was used in the experiments. Three row spacings (RS) (20, 30 and 40 cm) were applied. The experimental units had an area of 12 m2 (2.4×5) in size and equal seed rate was used in each experimental unit (on 150 kg ha -1 ). Higher plant height (127.8 cm) was recorded under 20 cm RS, compared to 30 (121.8 cm) and 40 cm (121.2 cm). The average green forage yield was 26.7, 27.7, and 28.8 t ha-1 for 40, 30, and 20 cm RS, respectively. Whereas the average hay yields for 20, 30, and 40 cm RS were 5.20, 5.34, and 5.79 t ha-1 , respectively. Crude protein (CP) ratio was significantly lower for 40 cm (20.2%) RS compare to 20 (22.5%) and 30 (21.6%) cm RS. Average raw ash, dry matter uptake (DMI) and relative nutritional value (RFV) ratios significantly increased in 30 cm and 40 cm RS compared to the 20 cm. However neutral detergent fiber (NDF) ratio decreased in 30 cm and 40 cm RS compared to 20 cm. Acid detergent fiber (ADF) and digestible dry matter (DDM) were not significantly affected from RS. In conclusion, 20 cm RS would be more suitable and economical due to higher plant height, green forage and hay yields, and higher CP and NDF rates for commercial feed producers in the region. However, 30 cm RS may be more suitable for farmers producing feed for their own livestock due to higher DMI and RFV values.

    Supplementation of Silicon Oxide Nanoparticles Mitigates the Damaging Effects of Arsenic Stress on Photosynthesis, Antioxidant Mechanism and Nitrogen Metabolism in Brassica Juncea
    (Nature Portfolio, 2025) Faisal, Mohammad; Ozcinar, Aynur Bilmez; Karadeniz, Erdal; Faizan, Mohammad; Sultan, Haider; Alatar, Abdulrahman A.
    Nanoparticles (NPs) represent one of the most promising platforms for addressing challenges in drug delivery, biosensing, and the development of advanced biotechnological tools. These innovative materials are revolutionizing modern agriculture by enabling precision farming practices that optimize resource utilization and enhance crop productivity. This study investigates the role of silicon oxide nanoparticles (SiO2 NPs, 200 ppm) in mitigating arsenic (As, 50 mu M) toxicity in Brassica juncea. The results demonstrate that As stress significantly impaired morphological and physiological parameters, as well as the accumulation of key metabolites, including flavonoids, phenolics, proteins, soluble sugars, and free amino acids. However, foliar application of SiO2 NPs effectively alleviated As-induced toxicity by enhancing antioxidant enzyme activities and maintaining nutrient homeostasis. The application of SiO2 NPs also positively influenced growth parameters, net photosynthetic rate, stomatal conductance, and soluble sugar content. Notably, SiO2 NPs improved the transpiration rate by 52%, leaf nitrogen content by 33%, and phenolic content by 42%. Furthermore, there was a significant reduction in oxidative stress markers, with hydrogen peroxide and malondialdehyde levels decreasing by 41% and 39%, respectively, indicating reduced oxidative damage and lipid peroxidation. These findings underscore the promising potential of SiO2 NPs in mitigating As stress and offer valuable insights for promoting sustainable crop production under environmental stress conditions.

    Bitki Sıklığının Silajlık Mısır (Zea Mays L.) Çeşitlerinde Verim ve Kalite Özelliklerine Etkisi
    (2024) Karaaslan, Emel; Karadeniz, Erdal
    Bu çalışma, silajlık mısır çeşitlerinden ADA523, OSSK644 ve İNDACO'nun farklı sıra üzeri mesafe uygulamalarının (12, 16, 20 ve 24 cm) silaj verimi ve kalitesi üzerindeki etkilerini belirlemek amacıyla 2023 yılı ikinci ürün yetiştirme döneminde Mardin ilinin Kızıltepe ilçesinde gerçekleştirilmiştir. Araştırma süresince, çeşitli büyüme parametreleri ve verim unsurları detaylı bir şekilde incelenmiştir. Bu parametreler arasında bitki boyu, bitki sap çapı, yaprak oranı, yeşil ot verimi, sap oranı, koçan oranı, kuru madde oranı, kuru madde verimi ve ham protein oranı yer almaktadır. Elde edilen bulgular, bitki boyunun 256 ile 290 cm arasında değiştiğini, bitki sap çapının ise 20.8 ile 23.6 mm arasında olduğunu göstermektedir. Yeşil ot verimi açısından incelendiğinde, bu değerlerin 7166 ile 8510 kg arasında değiştiği gözlemlenmiştir. Yaprak oranı %18.5 ile %22.1 arasında, sap oranı %48.2 ile %53.9 arasında ve koçan oranı %24.6 ile %33.3 arasında değişiklik göstermiştir. Kuru madde oranı %27.2 ile %29.2, kuru madde verimi ise 1977 ile 2442 kg/da aralığında bulunmuştur. Ham protein oranı ise %7.3 ile %8.5 arasında değişiklik göstermektedir. Çalışma sonuçlarına göre, en yüksek yeşil ot verimi ve kuru madde verimi, ADA523 çeşidinin 16 cm sıra üzeri mesafe ile ekilmesi sonucunda elde edilmiştir. Bunun yanı sıra, en yüksek ham protein oranı ise İNDACO çeşidinin 20 cm ve 24 cm sıra üzeri mesafe ile yapılan ekimlerinden elde edilmiştir. Bu bulgular ışığında, Kızıltepe ekolojik koşullarında ADA523 çeşidinin 16 cm sıra üzeri mesafede ekimi önerilmektedir. Anahtar Kelimeler: mısır, çeşit, sıra üzeri mesafe, verim
