Shahriar Hasan | Soumitra Saha | Md. Safiul Islam Afrad | Md. Riazul Islam | Robius S. Sadi | Md. Tasmir R. Labib
The main focus of this research was to explore the present status of pineapple cultivation in Madhupur tract of Bangladesh. Primary data were collected using a pre-designed and pre-tested questionnaire by face-to-face interviews from a sample of 300 pineapple growers and two focus group discussions were also carried out from March to May 2022. According to the study findings majority (51%) of the respondents cultivate pineapple in their own land having medium experience (53.3%), followed mixed cropping pattern (89%) where 25.33 percent respondent cultivate banana as companion crop. ‘Calendar’ is the top most cultivated variety of pineapple in Madhupur tract. Majority of the respondent use balanced pesticide and ripening agent due to increasing demand of chemical free farm fresh pineapple among consumers. Higher profit compared to other crops (82.00 %) was the main reason for producing pineapple in the study area. Majority (26.67%) of the respondent followed (Grower- Faria- Bepari- Aratdar- Wholesaler- Retailer- Consumers) channel among the six dominant marketing channels to market their produced pineapple. The results of SWOT analysis revealed that weakness of pineapple cultivation in Madhupur tract have the potential to improve. If the government and other policy making organizations come forward to solve the problems arising in pineapple cultivation, then the position of pineapple as fruit will be consolidated soon in home and abroad.

Mustafa Yaşar | Nurettin Baran | Yusuf Güzel Demiray | Remzi Ekinci | Yaşar Karadağ
In this study, seeds of cotton plants were coated with different boron concentrations and their effect on seedling growth was investigated. The experiment was carried out at Muş Alparslan University, Faculty of Applied Sciences, Department of Plant Production and Technologies, under laboratory and greenhouse conditions, according to the Randomized Plots Trial Design with 4 in laboratory and 3 in greenhouse replications, respectively. In the study, Di-sodium tetraborate decahydrate (Na2B4O7.10H20) (M=381.37 g mol-1) with a minimum purity of 99% boron compound have been used in different doses; 0 (control), 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250 and 2500 mg kg-1. According to the results of the regression analysis, it was determined that as the boron dose in the application increased, the root length was positively correlated and other parameters were negatively correlated. In terms of the parameters examined, 250 mg kg-1 Kaolin+liquid K-Humate (15% HA) 400 ml kg-1 (U3) boron application under laboratory conditions showed better results, and 1000 ml kg-1 Kaolin+liquid boron application under greenhouse conditions. It was determined that the application of K-Humate (15% HA) 400 ml kg-1 (U6) promoted growth. In addition, it was found that the results were confirmed in the grouping of the relationships between applications and parameters with heat map clustering and PCA graphs. As a result, it was determined that the toxic range of boron applications applied to the seed in the cotton plant was very narrow, and that it promoted seedling development and root elongation in the U6 application, but it was concluded that the study should also be studied in field trials in order to make more decisive decisions.

2023
Ali Karagöz | Orhan Kandemir
One of the most important impacts of the Covid 19 pandemic that broke out in China in the last months of 2019 was on the agricultural sector and, consequently, on the food supply. This situation manifested itself in an increase in food insecurity and food prices in countries around the world, and rising food prices highlighted the risk of undernourishment. The study attempted to statistically represent the impact of the pandemic on food security and food price increases in countries around the world. The study first compared the pre-pandemic and pandemic periods in terms of three basic indicators, such as food security, food prices, and undernourishment rates, and examined whether there was a significant difference between the two periods. Within the context of these three indicators, an attempt was then made to determine whether the negative impact of the pandemic was more severe in low-income countries. The results of the analysis showed that food prices, food insecurity, and undernourishment increased during the pandemic and that these impacts were relatively greater in developing countries. Therefore, the financial burden of these negative impacts associated with food supply was greater in developing countries.

Hatice Yaren Kuloğlu | Murat Boydak
The aim of this study is to histologically and histochemically determine the developmental and involutional stages of bursa of Fabricius of henna partridge (Alectoris chukar). In the study, bursa of Fabricius of 12 3-month-old (6 males, 6 females), 12 6-month-old (6 males, 6 females) henna partridges purchased from a private farm were used. It was observed that bursa of Fabricius was surrounded by a connective tissue capsule and consisted of tunica serosa, tunica muscularis, and tunica mucosa layers from the outside to the inside. It was seen that the tunica muscularis consisted of outer longitudinal and inner circular smooth muscle fibers. It was observed that the tunica mucosa made plicae towards the lumen of the organ and consisted of 10-15 plicae. It was seen that lamina epithelialis and lymph follicles were present in each plica. It was determined that the lamina epithelialis consisted of two parts called FAE (Follicle-Associated Epithelium) and IFE (İnter Follicular Epithelium). It was noted that the lymph follicles contained cortex and medulla sections and were separated locally by capillaries together with cortical medullary boundry cells. In the Methyl Green-pyronin staining method, plasma cells were found in the bursa of Fabricius of the henna partridge, in the connective tissue surrounding the organ, around the blood vessels and inside the follicles. In AB pH=2.5 staining, AB-positive reaction was seen only in the apical part of the epithelial cells forming FAE and IFE in the pre- and post-involution period. In PAS staining, PAS-positive reaction was observed only in the apical part of the epithelial cells forming FAE and IFE in the pre- and post-involution period. In PAS/AB pH=2.5 combined staining method, AB-positive reaction was observed only in the apical part of epithelial cells in the pre- and post-involution period. As a result of this study, it was found that bursa of Fabricius of the henna partridge did not undergo any histochemical changes despite its histologically large differences after involution.

2023
Fatih Kural | Ali Coşkan
In the study, the impact of employing vermicompost to boost oil rose (Rosa damascena Mill.), a native of Isparta province, to improve yield and nutrient content, was explored. Four different doses (V0: 0 kg ha-1, V1: 1000 kg ha-1, V2: 2000 kg ha-1, and V3: 3000 kg ha-1) of vermicompost were tested in the field conditions at 3 replicates. Vermicompost was applied to the canopy projection area and incorporated into the soil. Flower harvest was started on April 30, 2018, and throughout 20 days, the blooming flowers were collected and weighed daily basis. Following the harvest, leaf samples were collected from the plants, and the concentrations of certain macro and micronutrients were assessed.The study's findings demonstrated that applying vermicompost boosted the yield of oily rose blooms. The greatest yield value was determined to be 5850 kg ha-1 at a vermicompost dose of 2000 kg ha-1, which was 660 kg ha-1 greater than the control application. It was observed that vermicompost treatments had no significant influence on plant nutrient concentrations. This condition is assumed to be related to the removal of minerals from the plant during harvest. The findings indicate that the usage of vermicompost can contribute in the production of oil roses, and a dose of 2000 kg ha-1 can be suggested. This research establishes the feasibility of employing vermicompost in oil rose cultivation and sets the framework for future research.

The use of cassava for fuel ethanol production in Nigeria is supported by the Nigerian Biofuel Policy and Incentives (NBPI) of 2007. Because of its food, feed and industrial value, the need to replace cassava with crops/plants that are food and feeds neutral has motivated this research. Starch was extracted from forest anchomanes (FA) (Anchomanes difformis (Bl.) ENGL.) tubers and some of its physicochemical and elemental properties were determined. At present, the plant is uncultivated in Nigeria and other parts of Africa where it is found. Results showed that the starch content in FA tubers varied from 72.12 to 75.83%. Starch granules from all parts of the FA tubers had similar proximate, antinutrients and elemental properties and appeared usable for fuel ethanol production. However, to suggest its potential to sustainably replace cassava, further investigations are needed beyond these initial results.

This study evaluated the possibility to use pomegranate peel: an agro-industrial bay product as a conservative agent for fruit juice. Extraction of active compounds of. Punica granatum L. peels was made by maceration with ethanol and the evaluation of antioxidant and antimicrobial activity were conducted using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and disk diffusion method in agar medium, while self-life tests of orange juice monitoring the pH, total soluble solids, titratable acidity, cloud value, browning index and total mesophilic germs were conducted during 18 days. The results highlighted that pomegranate peel extract (PPE) showed a higher phenol and flavonoid content and strong antioxidant activity with an inhibitory concentration (IC50) of 6.22 μg / mL, as well as the antimicrobial activity indicated a higher inhibitory effect. Furthermore, shelf life tests showed a significant effect on browning index, titratable acidity, and lowering of microbial growth during storage compared to the controls, while pH, total soluble solids, and cloud value are not affected. These results allow us to consider pomegranate peel extract as a potential conservator for healthy and sustainable food.

Jeniffer Wanjuhi Wainaina | Ufuk Gültekin
This study used reports from various bodies to determine the competitiveness of some selected agricultural products between Kenya and other East African Community countries. Agriculture is an important sector in Kenya and the greater East African Community organization as it earns the country foreign exchange through exports. The sector possess considerable potential, and carrying out a competitive study would greatly inform the country’s efforts and policy making processes. The methods used were Market Share Index, Vollrath’s Relative Trade Advantage Indices, and Balassa’s Revealed Comparative Advantage Index. The various countries were compared using calculated indices and ranked accordingly based on their scores and market share percentages. Consequently, Kenya had a competitive advantage and dominated the international markets in tea and crude materials, whereas most East Africa Community member states had a strong comparative advantage in coffee. Generally, to stimulate the agricultural sector and diversify agricultural exports, the Kenyan government and private sector must increase high-level investments in agribusiness and transition from exporting raw materials to value-added products. Developing standard agricultural trade policies would benefit all East African Community member states, which is consistent with their goals.
