    Determination of awareness levels of walnut producers in plant protection applications (a case study of Bitlis province)
    (2022) Kaplan, Mehmet; Demir, Cihan
    The survey was conducted in 2020 to determine the awareness level of walnut producers regarding crop protection practices in Adilcevaz and Hizan districts of Bitlis province, where walnut production is widespread. With this in mind, a face-to-face survey was conducted using a simple random sampling method among 87 producers in a total of 10 randomly selected villages from two districts. Within the scope of the research, walnut growers were found to be highly educated and most had non-agricultural income. The manufacturers in question take into account the recommendations of sellers and Agriculture and Forestry department when choosing pesticides and deciding on the usage dose rates, that the brand recognition and active ingredients are important to pesticide preferences, that they don't use the same pesticides in the fight against the same diseases and pests, They start spraying without seeing the signs of disease and harmful factors in the plant, they apply the recommended dose in drug applications, pesticides used leave residue on product. They observe the waiting time between spraying and harvesting and wear protective clothing and masks during spraying, they do not simply throw-away empty pesticide box and packages used after the application into the agricultural fields or their surroundings, they clean the sprayer, but they use the sprayer without calibration, they mix pesticides and prefer cultural methods over chemical methods, and they do not have any knowledge about the word biopesticide. It is known that producers generally choose chemical control in the solution of plant protection issues, and the indiscriminate use of these pesticides has many adverse effects on human and environmental health.

    (Pakistan Botanical Soc, 2023) Turan, Nizamettin; Seydosoglu, Seyithan; Baran, Mehmet Firat; Demir, Cihan
    The study's goal is to assess the energy balance of fodder pea crop production.and greenhouse gas (GHG) emission under Mus conditions, Turkey in 2020. Basic information such as the economic life of the instruments and machines utilized in the study, work success, fuel-oil consumption, machine weights and the amount of used fertilizer and seed were obtained by current measurements, from other studies, various sources and catalogs. The evaluations resulted in the determined energy output/input ratio, the specific energy value, and energy productivity. and the net energy efficiency values for feed pea crop production were 5.10, 3.65 MJ kg-1, 0.27 kg MJ-1 and 35636.85 MJ ha-1, respectively. The fertilizer energy had the highest energy utilization rate of the overall energy inputs for feed pea production, with 31.35%.. This was followed by seed energy with 25.77%, fuel energy with 21.40%, machine energy with 14.93% and human energy with 6.55%, respectively. Total GHG emission for forage pea crop production was calculated as 1533.81 kgCO2-eqha-1. The highest share in total GHG emissions was at seedconsumption (59.69%). The seed was followed by human labor (13.23%), nitrogen fertilizer consumption (9.12%), phosphate fertilizer consumption (6.02%), machinery use (6.0%) and diesel fuel consumption (5.94%). Furthermore, the GHG ratio in the production of fodder pea crops was calculated to be 0.65 kgCO2-eqkg-1. As a result, fertilizer energy had the biggest share of production inputs, followed by seed, fuel, machinery, and human labor energies, respectively. Total GHG emission and the GHG ratio was calculated as 1533.81 kgCO2-eqha-1 and 0.65 kgCO2-eqkg-1, respectively.

    Energy Balance and Greenhouse Gas Emissions of Cherry Production in Turkey
    (Springer, 2024) Gokdogan, Osman; Demir, Cihan; Baran, Mehmet Firat
    The aim of this study was to determine the energy use efficiency (EUE) and greenhouse gas (GHG) emissions in cherry production in K & imath;rklareli province of Turkey. It is also aimed to increase the EUE and reduce GHG emission. Furthermore, this comprehensive study conducted in K & imath;rklareli province of Turkey will contribute to the literature. Observation, survey and data calculations are from the 2020-2021 season. Data provided in the study were acquired from 50 (reachable) farms by conducting face-to-face surveys with complete count method in 2022. This study included calculations of energy input (EI), energy output (EO), EUE, specific energy (SE), energy productivity (EP), net energy (NE), EI types, GHG emission and GHG ratio. EI and EO were calculated as 14,934.30 MJ/ha and 14,234.67 MJ/ha, respectively. Among all the energy inputs, the greatest share belong to chemical fertilisers by 34.49%. EUE, SE, EP and NE were calculated as 0.95, 3.07 MJ/kg, 0.33 kg/MJ and -699.62 MJ/ha, respectively. The consumed total EI in production has been classified as 52.94% direct energy (DE), 47.06% indirect energy (IDE), 45.94% renewable energy (RE) and 54.06% non-renewable (NRE). Total GHG emissions and GHG ratio were calculated as 295.48 kgCO2-eq/ha and 0.06 kgCO2-eq/kg, respectively. Increasing the ratio of RE by using farmyard manure and organic manure rather than chemical fertilisers is important to increase the EUE and reduce GHG emission levels. In order to reduce emission quantities, it is necessary to increase the use of RE inputs. These proposals considered in cherry production can increase EUE and reduce GHG emission.

    Enhancing Iron Content in Potatoes: a Critical Strategy for Combating Nutritional Deficiencies
    (Springer, 2024) Mushtaq, Zain; Alasmari, Abdulrahman; Demir, Cihan; Oral, Muekerrem Atalay; Belliturk, Korkmaz; Baran, Mehmet Firat
    Despite recent advances in the prevention and control of nutritional deficiencies, estimates suggest that over two billion individuals worldwide are at risk for vitamin A, iodine and/or iron insufficiency. Pregnant women and small children are most at risk, and Southeast Asia and sub-Saharan Africa have very high incidence rates. Concerning public health are deficits in zinc, folate and the B vitamins, among other micronutrients. Micronutrient malnutrition, often referred to as hidden hunger, represents one of humanity's most pressing challenges. Iron deficiency anaemia affects more individuals globally than any other prevalent disorder. However, iron supplementation can exacerbate infectious diseases, necessitating careful evaluation of iron therapy policies. In this review, we explore biofortification strategies to combat hidden hunger, considering recent medical and nutritional advancements. Enhancing iron content in edible plant parts can improve human nutrient status through crop consumption. Mineral and vitamin density in staple foods, particularly for impoverished populations, can be increased using traditional plant breeding or transgenic approaches, collectively known as biofortification. Microbial iron biofortification is especially valuable in developing countries where expensive supplements are unaffordable. Additionally, the current COVID-19 pandemic underscores the need for a robust immune system, with iron playing a crucial role in immune function enhancement.

    Sulphur and Boron Fertilization Increased Productivity of Boro Rice (BRRI dhan28) by Increasing Pollen Fertility and Agronomic Efficiency in Calcareous Soils
    (2023) Barı, Akm Abdul; Promı, Razita Jalil; Muhyıdıyn, Imam; Pramanık, Moaz Hosen; Demir, Cihan; Erman, Murat; Çığ, Fatih
    To study the effect of sulphur (S) and boron (B) on the performance of yield, agronomic efficiency, economic return of boro rice (cv. BRRI dhan28) was evaluated at the Reseahc Field of the Department of Crop Science and Technology, University of Rajshahi, Rajshahi- 6205, during the Rabi season from November 2015 to April 2016 in High Ganges River Floodplain under AgroEcological Zone-11 (AEZ-11). The experiment was consisted three level of sulphur, viz., S0: without sulphur (control), S20: 20 kg S ha-1, S30: 30 kg S ha-1, and three level of boron viz., B0: without boron (control), B2: 2 kg B ha- 1, B3: 3 kg B ha-1. The experiment was conducted in a Randomized Complete Block Design (RCBD) with three replications. The results revealed that S and B significantly influenced the yield straw yield, biomass yield, sterility percentage, agronomic efficiency and economic return of BRRI dhan28. The treatment combination of S20B2 (20 kg S ha-1 with 2 kg B ha-1) performed the best results of the aforesaid traits. So, it can be suggested to apply S at 20 kg ha-1 and B at 2 kg ha-1 with recommended dose of NPK and Zn for maximizing yield, agronomic efficiency and economic point of view of boro rice in calcareous soils of AEZ-11.
