Agricultural farming is a complicated system that involves continuous interactions among its multiple components over a period of time. The series of activities involved in farming practices have enormous contributions to ensure food security for the humanity. With the passage of time, agriculture sector faces diversified challenges like high food demand of rapidly growing population, scarcity of available resources and adverse effect of climate change. In developing countries like Bangladesh, food sufficiency is mostly achieved through intensive farming which has detrimental effects on natural resources, surrounding environment, and the whole ecosystem. The review attempts to discover the potentials of conservation agriculture practices for sustainable crop productivity and economic profitability of smallholder farmers in Bangladesh. This study revealed that conservation farm management practice is a cost-effective modernized technique that has the ability to accelerate crop productivity and farmers income through minimum utilization of agricultural inputs. Although the concept of conservation agriculture is widely practiced in other parts of the world, Bangladesh is experiencing a slow rate of adoption during the last few years. The policy implication of the study suggests that the government should take coordinated and combined initiatives involving both public and private sector organizations to incorporate this concept into the mainstream agricultural system of Bangladesh.

The present study examined the physicochemical properties, antioxidant activity (DPPH, ABTS, and FRAP), and sensory properties of aronia marmalades prepared with different cooking methods (CM) (boiled (B) and pressure-boiled (PB)) by adding sugar (S) and stevia prebiotic fiber sweetener (SP). Ash, reducing sugar, sucrose, viscosity, L*, a*, b*, C*, and H° values, and total sugar content of aronia pulp and marmalades differed significantly by cooking method and sweetener type (ST). Hydroxymethylfurfural could not be detected in aronia pulp and marmalades. Concerning CM, TPC (total phenolic content) and TMA (total monomeric anthocyanin) values were found to be significantly higher in PB cooking than in the B cooking method. On the other hand, TFC (total flavanoid content) was statistically higher in boiled marmalades. According to CM, the DPPH antioxidant activity of marmalades was significantly higher in B marmalades. The TPC, TMA, TFC, and antioxidant properties of marmalades differed sigficantly by ST. The TPC of marmalades prepared with SP addition was higher than that of S-added marmalades and control. According to ST, whereas the antioxidant activities (DPPH, ABTS, and FRAP) of S and SP-added marmalades were lower compared to the control, the antioxidant activities determined by DPPH and ABTS among S and SP-added marmalades were higher in SP-added marmalades. The panelists gave the highest scores to BSC (boiled S-added marmalade). Considering the overall acceptance scores, the second highest score was given to BST (boiled SP-added marmalade). In other words, in terms of sensory evaluation, boiled marmalades received higher overall acceptance scores, while PBST (PB SP-added marmalade) received the lowest scores. According to these results, astringency components decrease with cooking in an open vessel. Furthermore, it can be said that sugar masks this astringent taste.

Sunulan çalışmada solunum yolu hastalığı belirtileri gösteren koyunlarda genel fiziksel ve özel klinik muayene bulgularının, tam kan sayımı sonuçlarının ve nazofarengial sürüntü örneklerinin incelenmesi amaçlandı. Çalışmada solunum yolu hastalığı şikâyeti bulunan bir İvesi koyun sürüsünde (n:62) alt solunum yolu hastalığı belirtileri tespit edilen 18 adet dişi koyun kullanıldı. Hasta koyunların yaş kayıtları tutuldu, genel fiziksel muayeneleri gerçekleştirildi. Özel klinik muayene parametrelerinin her biri kendi içinde skorlandı. Hasta koyunlar akciğer oskultasyon skor sonuçlarına göre “Hafif Hasta (n:11)” ve “Orta Hasta (n:7)” şeklinde iki gruba ayrıldı. Hasta hayvanlar da dahil bütün koyunlardan antikoagülantlı ve antikoagülantsız kan örnekleri alındı. Antikoagülantlı kan örneklerinden tam kan sayımı yapıldı. Hasta (n:18) ve sağlıklı (n:6) koyunlardan mikrobiyolojik ve virolojik analizler için steril swap ile nazofarengial sürüntü örnekleri alındı. Kan (n:62) ve nazofarengial sürüntü (n:24) örneklerinden Bovine herpesvirus tip 1, Respiratorik sinsityal virus (RSV), Parainfluenza 3 (PI-3) ve Pestivirus varlığına yönelik analizler gerçekleştirildi. Hafif hasta ve orta hasta koyunlar karşılaştırıldığında, yaş, dakikadaki kalp atım sayısı, klinik durum gözlem skoru, MCH Pg, MCHC g/dL verilerinde gruplar arasında anlamlı farklılık (P<0,05) tespit edildi. Sağlıklı ve hasta olan koyunların nazofaringeal örneklerinde baskın olarak sırasıyla Staphylococcus spp., Streptococcus spp. ve E. coli  bakteri türleri izole edildi. Klinik olarak sağlıklı görünen bir koyundan Klebsiella spp. izole edilirken, yalnızca bir hasta koyundan M. haemolytica izole edildi. Sağlıklı görünen bir koyunda serolojik olarak BoHV-1-spesifik antikor tespit edildi. Sonuç olarak saha şartlarında uygulanabilecek en kolay ve en hızlı yöntemler arasında yer alan akciğer oskultasyon bulguları ve nazofarengial sürüntü sonuçları ile muhtemel etiyolojik etken ve hastalık durumu hakkında öngörüde bulunulabilir. Bu sayede ekonomik değere sahip bu hayvanlarda erken muhtemel tanı ile tedaviye başlanarak ekonomik kayıplar azaltılabilir.

Chlorophyll meters manage both the amount and duration of nitrogen fertilizer application based on the principle that the chlorophyll or nitrogen content of plants should be maintained throughout their development. For smallholders in developing countries, the use of a hand-held meter to manage nitrogen fertilizer in rice and wheat is the most popular method. The adoption of nitrogen management strategies based on close sensing using chlorophyll meters and optical sensors will largely depend on the inclusion of specific economic analysis in future research. The importance of using sensors and chlorophyll meters for nitrogen fertilizer management depends on how successful current practices have been. In this study, five different nitrogen rates (0, 80, 120, 160, 200 kg N ha-1) were applied to two different wheat varieties, and the effect of these different nitrogen rates on wheat protein content was investigated in a randomized block design. A quadratic polynomial model described the relationship between protein content and nitrogen rates.

Hidabu Abote, Dera, Wera Jarso and Debra Libanos districts of North Shewa zone are potential in honey production. To enhance this potential, different organizations disseminate improved beehives technologies for the smallholder farmers. However, the impact of the disseminated technologies on household income has not been evaluated. Thus, this study aimed to evaluate the impact of improved beehive adoption on household income. Purposive and two stage sampling technique was used to select 384 sampled households. The study used logistic regression model to identify the determinants of adoption decision of modern beehive technology while propensity score matching to evaluate the impact of modern beehive technology adoption on household income. The result of logistic regression model shows that age of household head, family size, households experience in beekeeping, frequency of extension contact, access to credit services, access to training and access to beehive demonstration site visit had positive and significant effect on household adoption decision of modern beehive technology. The result of propensity score matching indicates that the adopters of improved beehive technology were earned Birr 2690.383 than non-adopter. The difference in household income between the two groups shows that there is considerable room for improvement of household income through increasing the number of adopter of improved beehives technology in the study area. This should be done through provision of training, credit, extension and expansion of beehive demonstration site among the others.

In the current paper, it was aimed to detect the SSR markers that can be used in the prevention of confusion that may occur in breeding or nurseries, and directly genetically separating Uzun and Kırmızı pistachio cultivars from other commercial cultivars. A total of genotypes of 16 Pistacia vera species, one P. atlantica, one P. eurycarpa and two P. terebinthus species were obtained from the farmer's orchard in Nizip district of Gaziantep province for genetic characterization. Genetic diversity and clustering analyzes were performed with UPGMA (Unweighted Pair Group Method with Arithmetic Average) and STRUCTURE 2.3.4 programs using the scored SSR loci. Genetic relationship and population structure of genotypes were defined using common and distinct polymorphic PCR fragments. Cultivar-specific markers to be used in identifying and distinguishing the genetic structure of Uzun and Kırmızı cultivars were carried out in the current research. CUPOhBa2127 marker has the highest allele number (Na=10). In addition, 11 out of 25 SSR markers were explained as cultivar-specific SSRs that can distinguish Uzun and Kırmızı cultivars. These markers can be used directly by breeders and geneticists without any preliminary screnning of the markers. A quite serious providence will be achieved in the cost and time that will occur with the preliminary analysis, and thus, the confusion that may occur in large scale orchard establishments or nurseries will be reduced to pretty low levels with DNA analysis.

Pseudomonas aeruginosa (P. aeruginosa), the most pathogenic species among the pseudomonas species, is a bacterium that causes opportunistic infections resulting in significant damage to host tissues. P. aeruginosa, which is resistant to antibiotics, also causes fatal infection in human and animals. Infections caused by P. aeruginosa are difficult to treat due to its rapid proliferation in the environment and its ability to form biofilms that confer resistance to antibiotics. One of the main virulence factors of P. aeruginosa is its direct damage to host tissues, which disrupts the host’s defense mechanisms. P. aeruginosa is a food-borne pathogen often detected in various food groups such as meat, milk, fruit, vegetables, and water. In recent years, there has been a noticeable rise in food-borne contamination with P. aeruginosa. New measures are urgently needed in the treatment of patients with infections due to this agent, since P. aeruginosa can develop resistance to most antibacterials. In this review, general information about P. aeruginosa, which has gained importance for public health, will be given.

The study described herein aimed to investigate the relationship between perceptions of hormone usage and customer preferences for broiler meat and meat products in Sri Lanka with special reference to Kandy district. A total of 460 respondents from Kandy district were interviewed using a pre-tested questionnaire. The analysis revealed that 85.9% of the respondents believes the fact that the hormones are used in broiler production. Also, 75.7% of the respondents were unaware about the fact that the hormones are totally banned from Sri Lankan broiler production. Around 71.4% believed that the hormones are still being used illegally in broiler production in Sri Lanka. The study also found that the general public (36.2%), was the main source that the respondents perceived this false information concerning hormone use. Similarly, 83.7% believes that these chemical substances create health hazards to human. 76.7% of the respondents strongly believed the fact that the adolescent girls who consume broiler meat regularly during their childhood may experience early puberty. The findings of the present study concluded that three misconceptions of (i) use of hormones to attain high growth rates in broilers (ii) hormones assumed to be present in broiler meat pose health hazards to public and (iii) frequent broiler meat consumption during childhood is accompanying with the early puberty in adolescent girls, do exists. Though the majority of the sample comprises of highly educated professionals, these misinformation were spreaded from the information generated among the general public. However stipulating a valid certification with no added hormone in broiler chicken meat will be helpful in changing the mind-set of general public.

The cultivation and the usage of maize have been significantly increased across all provinces of Rwanda. Nevertheless, the problem of aflatoxin contamination remains a major factor that renders them to be unfit for animal and human consumption. In this research, the effects of drying methods (sun drying, kitchen drying, dry shelter) post aflatoxin infection in maize were evaluated in Northern Rwanda. A randomized complete block design with four replications was used with maize variety (H628) with drying methods as the main plot. Maize samples were tested for aflatoxin using aflatest. In both seasons (2021 A and 2021 B) the aflatoxin results show that the aflatoxin infection levels were lower in maize dried with kitchen drying (1.4 ppb) compared to the samples dried with sun drying (1.6 ppb) and dry shelter (2.2). Also, it was seen that the three drying methods are good for reducing the aflatoxin infection levels lower than 10 ppb as standards limit for East African countries. The aflatoxin infection levels were found to be significant (≤10 ppb) as results of kitchen drying than sun drying and dry shelter methods. This research resulted that proper drying such as drying maize on kitchen fire (kitchen drying) produce the lower level of aflatoxin infection in maize.

As a result of climate change and the ozone layer spoilage, harmful rays of the sun such as UV reach the world more and harm agricultural production. To be protected from the harmful effects of UV, not only human beings, but all living organisms have developed different characteristics. In recent years, pigments with radiation absorbing and antioxidant properties have been used against UV damages. In this study, the effect of carotenoid pigments obtained from bacteria and fungi on the lettuce plant (Lettuce Yedikule 5701) was investigated due to its high antioxidant and UV protection properties. Pigment solutions partially purified from microorganisms were sprayed onto the plants. While an increase was detected in the amounts of hydrogen peroxide (H2O2) and lipid peroxidation (LPO) in the lettuce plant with the effect of UV, a decrease was observed in these parameters when applied with pigment solutions. With the same application, microbial pigments protected the plant against the harmful effects of UV by increasing the antioxidant enzyme activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POX) and the amount of chlorophyll. As a result of this study; It has been determined that microbial pigments, which can be obtained easily and with low costs, have protection properties against the harmful effects of UV and provide the plants with properties to resist the stress.
