Effect of Vermicompost Application on Mineral Nutrient Composition of Grains of Buckwheat (Fagopyrum esculentum M.)
(Mdpi, 2021) Ozyazici, Gulen; Turan, Nizamettin
Poor soil organic content is a major cause of declining crop productivity in developing countries. Less precipitation and high temperatures oxidize organic matter in the soils of semi-arid regions. Such a deficiency in the organic matter of the soils decreases the bioavailability of many nutrients. Organic amendments like vermicompost (VM) have the potential to overcome this problem, while decreasing the dependency on inorganic fertilizers. Thus, the aim of our study was to explore the best application rate of VM for the improvement of nutrient contents in buckwheat. We used two buckwheat cultivars i.e., Aktas and Gunes were sown under variable rates of soil-applied VM (0, 0.75, 1.50, 2.25 and 3.00 t ha(-1)) in semi-arid highland conditions. The results demonstrated that the nutritional quality parameters were improved when VM was applied at the rate of 2.25 t ha(-1). In addition, VM at 2.25 t ha(-1) resulted in an improvement of the N and P contents of the grains. The P contents in the grains of the Gunes variety was higher (0.26%) than the Aktas variety (0.24%). A significant improvement in Fe (%), Cu (%), Zn (%) and Mn contents (%) in the grains of buckwheat validated the efficacious functioning of 2.25 t ha(-1) of VM. The Zn content of the grains was higher in the Gunes variety (34.06%) than the Aktas variety (31.96%). However, no significant change in K, Ca and Mg was noted at any level of VM in both Aktas and Gunes. It is concluded that a 2.25 t ha(-1) VM application in the buckwheat crop under zero conventional fertilizer was the best level to boost the nutritional quality of the grains.
Evaluation of Grain Maize Harvest Residues as Fodder After Partial Torrefaction Under Microwave
(2023) Seydoşoğlu, Seyithan; Turan, Nizamettin
With a project supported by Siirt University (Siirt, Türkiye), we determined the conversion potential of residues of field cropped grain maize into animal feed via torrefaction. Torrefaction application was performed in a microwave device for four different periods of time (0, 4, 8, and 12 minutes) in three replications at three different watts (300, 600, and 900 watts). The dry matter digestion was determined for the ground starter and final materials by the Daisy Incubator Technique (ANKOM). Changes in dry matter, protein, and ADF values were measured by standard feed quality analyses. The effects of applications on dry matter ratio, protein, and in vitro digestibility were found to be statistically significant, whereas the effect on ADF ratio was insignificant. Low-term torrefaction applications significantly increased the dry matter ratio, whereas high power and long application periods significantly increased the protein ratio. In vitro, digestibility was decreased due to the increase in the power application and duration of torrefaction. A material with high dry matter and high protein content but low in vitro digestibility was obtained as a result of the torrefaction applications tested in the study under microwave conditions with grain maize harvest residues. Although the applications tested have decreased the value of maize harvest residues as cattle feed, the obtained material with high dry matter and protein content with this torrefaction method has the potential to be used as a nutrient medium in different living environments (e.g. bacterial or fungal) which may be subjected to further investigations.

(2024) Seydoşoğlu, Seyithan; Turan, Nizamettin; Kökten, Kağan; Özdemir, Selim
Sweet sorghum crop produces grains at its ear-head which can be utilised as food and feed, produces stalks for the production of syrup, bio-ethanol, bio-diesel, bagasse and green foliage for use as organic fertiliser and excellent animal fodder. Approximately 4000 sweet sorghum cultivars are spread over the globe, providing a broad and varied genetic foundation for the development of highly productive, region-specific cultivars. A study was conducted to assess the grains of selected 10 different sweet sorghum varieties for the feed quality characters. For this aim, ADF, NDF, ADL, DMD, DMI, TDN, RFV, DE and ME values of sweet sorghum grains were determined. As a result of the study, crude ash, CP, ADF, NDF, ADL, DMD, DMI, RFV, TDN, DE and ME values were determined as 0.19-3.74%; 9.03-11.05%; 10.0-24.6%; 24.3-38.0%; 1.07-9.13%; 69.69-81.09%; 3.16-4.94%; 170.5-309.5%; 63.85-74.84%; 3.25-3.74 MJ/kg and 9.85-11.78 Mcal/kg, respectively. Variety \"Smith\" stands out with its ADF, NDF and ADL characteristics. Gülşeker, USDA-Taiwan and Erdurmuş varieties were significant in terms of CP. Ulusoy variety stands out with DMI, TDN, RFV, DE and ME.
GENETIC VARIABILITY FOR SEED NUTRITIONAL COMPOSITION IN PEARL MILLET GENOTYPES ANALYZED BY BIPLOT METHOD
(Univ Quindio, 2023) Seydosoglu, Seyithan; Kokten, Kagan; Cil, Abdullah; Turan, Nizamettin
This study evaluated the chemical composition of pearl millet seeds belonging to different genotypes by biplot analysis. Seeds of 26 different pearl millet populations obtained from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) within the scope of TuBITAK 219O103 run by Sirnak University were used. The seeds were ground and analyzed for their chemical composition, i.e., acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP), digestible dry matter (DDM) and dry matter intake (DMI) rate. The results revealed that crude protein ratio varied between 11.74-19.24%, whereas ADF ratio differed between 3.44-11.43%. Similarly, NDF ratio varied between 10.23-23.47%, while DDM ratio ranged between 79.98-86.21%. Likewise, DMI ratio differed between 5.11-11.72%. Scatter plot obtained after biplot analysis indicated three different groups based on the analyzed traits. The first group contained DDM and DMI, whereas the second group consisted of ADF and NDF. The protein ratio was in the third group. It was determined that ADF-NDF and DMI-DDM properties were negatively correlated with each other. According to biplot, genotypes 'A5-13', 'A13-6' and 'B1-7' were prominent for ADF-NDF, DMI-DDM, and protein ratio, respectively. Therefore, these genotypes can be used in future studies to induce the desired traits.
Greenhouse gas emission and energy analysis of vetch (Vicia sativa L.) cultivation
(Elsevier, 2023) Seydosoglu, Seyithan; Baran, Mehmet Firat; Turan, Nizamettin; Alfarraj, Saleh; Albasher, G.
Background: Agricultural production accounts for a major share of global energy consumption and greenhouse gas emissions (GHG). However, the information on energy use and GHG emissions from various crops is contradictory. Climate change is expected to increase the GHG emission from different crops; therefore, selection of the crops with lower GHG emission could be helpful in reducing the emission and energy consumption. A major focus of energy policy should be on improving energy efficiency. Saving money and lowering GHG emissions are only two benefits of using energy efficiently. However, these are unknown for the vetch cultivation in Siirt province of Turkey. Methods: This study investigated energy consumption efficiency and GHG emissions of vetch (Vicia sativa L.) production under dry circumstances in Siirt province, Turkey during 2021. Seed rate was kept 120 kg/ ha in the current study. The amount of fertilizer applied was 92.0 kg/ha pure phosphorus and 36.0 kg/ha pure nitrogen. To calculate the energy efficiency of vetch production in Siirt, energy inputs and energy outputs were computed. Results: The energy intake and output were 8205.02 MJ/ha and 90388.56 MJ/ha, respectively. The energy inputs were: 37.1 % diesel fuel energy, 31.2 % fertilizer energy, 21.2 % seed energy, 9.6 % equipment energy, and 0.9 % labor energy. The results revealed that energy consumption efficiency was 11.02, specific energy was 0.34 MJ/kg, energy efficiency was 2.90 kg/MJ, and net energy was 82183.54 MJ/ha in vetch production. Total GHG emissions from vetch production was 205.19 kgCO2-eq ha-1, with diesel fuel accounting for the lion's share (72.88 %). Diesel fuel was followed by the consumption of nitrogen fertilizer (26.33 %), phosphorous (0.47 %) and machinery (0.42 %). Additionally, GHG ratio was 0.009 kg CO2-eq kg-1 in vetch production. Conclusion: It is concluded that encouraging the farmers to produce vetch as an alternative to the production of conventional forage crops and rotation in fodder production will be beneficial. It will reduce GHG emissions with lesser energy consumption. (c) 2023 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.

(Pakistan Botanical Soc, 2024) Hosafioglu, Ibrahim; Akdeniz, Hakki; Turan, Nizamettin; Seydosoglu, Seyithan; Iqbal, Muhammad Aamir; El Sabagh, Ayman
The agro-botanical and qualitative testing of indigenous turfgrass species have remained neglected despite their enormous potential to provide nutritional herbage for dairy animals. A multi-year research was conducted to appraise the growth, herbage yield and nutritional quality performance of eight turfgrass species (Lolium perenne, Festuca arundinacea, Poa pratensis, Festuca rubra rubra, Festuca rubra comutata, Festuca rubra trichophylla, Festuca ovina, Agrostis tenuis) during 2015 and 2016 under the agro-ecological conditions of Igdir, Turkey. The experiment was carried out in a factorial design with three replications, while response variables included different agro-botanical traits and green herbage potential of turfgrasses under investigation. The results revealed that Festuca arundinacea remained superior for canopy covering rate, green herbage yield, plant height, root depth, leaf width, grass quality and greenness of leaf color.It was followed by Lolium perenne and Festuca rubra rubra. However, Festuca ovina and Agrostis tenuis performed below par to other turfgrass species during all seasons of both years. Therefore, turfgrass species 'Festuca arundinacea', Lolium perenne and Festuca rubra rubra may be recommended for obtaining significantly higher green herbage yield and quality in all three seasons (spring, summer and autumn) in Igdir, Turkey and in other regions of having similar agro-climatic conditions globally.

Climate change scenario has revitalized necessity to optimize agronomic management practices for boosting cereals productivity and nutritional quality. To observe the growth and quality attribute of maize hybrids under various planting densities and in order to sort out the most suitable plant population, a field experiment was conducted at the Research Farm, Faculty of Agriculture, Mustafa Kemal University during 2018. Six maize hybrids viz. DKC 6589, Carella, Pioneer 1921, 70 May 82, Cadiz and Bolson were grown using five planting densities (9, 10, 11, 12, and 13 plants m2). The experiment was laid out in split plot arrangement with three replications. Maize hybrids and planting densitides were placed in main plots and sub plots, respectively. Growth characteristics like ear length, weight and diameter, and quality trauts like protein, stach and oil content in grains were determined as response variables. The results revealed that increasing plant densities gradually reduced the growth paramters including ear length, weight and diamter. While, quality traits such as starch and oil contents of basal, middle and tip kernels were increased with the increase in plant densities, but the protein ratio was decreased. The genotypes mean values indicated that 70 May 82 and Carella remained superior for ear length, weight and ear dimater respectively. In contrast, Pioneer 1921 and Bolson outformed other hybrids as far as starch and oil contents were concerned.

Siirt İlinde Çayır Mera Alanlarından ve Yem Bitkilerinden Elde Edilen Kaba Yem Üretim Potansiyeli
(2015) Turan, Nizamettin; Özyazıcı, Mehmet Arif; Yalçın, Gülcan Tantekin
Özet: Siirt ilinin coğrafik yapısından dolayı halkın önemli bir kesiminin geçim kaynağı hayvancılık ve bitkisel üretime dayanmaktadır. Hayvancılık genellikle çayır-mera hayvancılığı şeklinde yapılmaktadır. Hayvansal üretimde vazgeçilmeyen en önemli yem grubunu kaba yemler oluşturmaktadır. Hâlihazırda Siirt ilinde çayır mera kaynaklı üretilen kuru ot miktarı 130.461 ton, yem bitkileri kaynaklı kuru ot miktarı 60.177 ton civarındadır. Buna karşılık Siirt ilinde 101.899 büyük baş hayvan birimine eşdeğer hayvan varlığı bulunmaktadır. Bu hayvanların yıllık ortalama yaşama payı için kaba yem ihtiyacı ise 464.914 tondur. İlin doğal çayır mera alanlarından ve yem bitkileri ekilişlerinden elde edilen toplam kaba yem üretimi 190.638 ton olup, sahip olduğu hayvan varlığının ancak % 41ine yetecek kadardır. Bu nedenle mevcut çayır mera alanlarında üretimi arttırmak için, amenajman tekniklerine uyulmalı ve ıslah çalışmalarına hız verilmelidir. Ayrıca, yem bitkileri ekim alanları arttırılmalı, özellikle nadasa bırakılan alanlarda ekim nöbeti sistemleri geliştirilerek yem bitkileri tarımına öncelik verilmelidir.

(Southern Cross Publishing, 2020) Hossain, Akbar; EL Sabagh, Ayman; Barutcular, Celaleddin; Bhatt, Rajan; Çiğ, Fatih; Seydoşoğlu, Seyithan; Turan, Nizamettin
The global population is predicted to expand to 9.1 billion by 2050. Countries around the Mediterranean Sea are predicted to achieve a combined population of 529 million by 2025. The current major challenge confronting sustainable agriculture in the Mediterranean region is climate change which has directly affected the extent and frequency of rain events, floods, and droughts, which in turn has influenced land and water productivity and farmers' livelihoods. The present review highlights the major consequences of climate change for sustainable crop production in the Mediterranean region and evaluates different mitigation strategies for improving agricultural land productivity and water use efficiency along with their impact on farmers' livelihoods. © 2020 Southern Cross Publishing.
Temperate Forage Legumes Production, Weeds Dynamics, and Soil C:N Economy Under Organic Wastes
(Springer Nature, 2022) Iqbal, Muhammad Aamir; Iqbal, Asif; Seydoşoğlu, Seyithan; Turan, Nizamettin; Ozyazici, Mehmet Arif; EL Sabagh, Ayman
Environmental pollution caused by leaching and volatilization of mineral fertilizers from agricultural fields especially in temperate climates has aggravated under changing climate. Utilizing organic wastes from poultry sheds and dairy farms for crops production can be a way forward towards their eco-friendly disposal and curbing environmental hazards. This review synthesizes and analyzes the use of organic manures for forage legumes production and their impact on feed value, soil fertility, microbial biomass, weeds infestation, and economic turnouts in temperate regions. The feasibility of adopting organic wastes as a conventional source of plant nutrients or continuity of their use as a fringe farming activity has also been assessed. The increment in the forage yield of legumes such as white clover, lucerne, red clover, sub-clover, birdsfoot trefoil, etc. under chemical fertilizers widened the yield gap between organic and mineral manures management systems. However, organic materials improved the nutritional quality of temperate legumes owing to increased activity of proteinase enzyme, better absorption, and utilization of nitrogen and phosphorous, production of effective carboxyl and hydro-carboxyl, ?-glucosidase activity along with the presence of growth-promoting hormones. Organic fertilization effectively enhanced soil carbon sequestration and microbial biomass, while labile carbon was increased by mineral fertilizers. However, organic manures recorded higher dry matter of weeds than traditional farming systems which reduced forage yield by 35–50%. Availability at farm, regional and global levels along with nutritional composition, biological viability, and economic competitiveness of organic wastes continue to remain challenges in their wide-scale adoption as plant nutrients source. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
