Sorghum is one of the major staple crops grown in the poorest and most food-insecure regions of Ethiopia. Sorghum production is predominantly based on local seeds with limited use of commercial fertilizer or other chemicals. This study is therefore aimed to demonstrate the improved sorghum variety with its improved management practices and to assess farmers’ and extension workers’ reactions. The newly released variety of Beletew was evaluated with the variety of Melkam. The experiments were implemented using a simple plot design with farmers’ fields as a replicate. The result revealed that in both locations, the studied varieties showed nonsignificant variation in grain yield. Besides, all the participant farmers were agreed that the variety Beletew had compacted panicle, a larger number of spikes per panicle, stayed green character and yellow seed color. Similarly, about 78.3% and 65.6% of the participant farmers from Efratana gidim and Ensaro Districts respectively agreed that the variety Beletew had a larger panicle size than the variety Melkam and expected higher grain yields from it. Therefore based on the grain yield performance of the result of farmers’ evaluation, the new variety of Beletew was recommended to be pre-scale on a wider scale to sorghum-growing lowland areas as an alternative shortmatured varieties.

This study was carried out to examine the prevalence of AFM1 contamination across different areas of Chattogram, Bangladesh, and to assess the level of AFM1 in raw milk samples from various dairy farms. A cross-sectional study was conducted to assess the farming standards of three different Chattogram neighborhoods—Bakalia, Khulshi, and Pahartali—and to ascertain the amount of AFM1 in milk. In the study location, 30 commercial dairy farms were randomly chosen, and data on farming methods, milk production techniques, and knowledge of aflatoxin contamination were gathered. Using the enzyme-linked immunosorbent assay (ELISA) method, collected milk samples (n = 90) were examined for the presence of AFM1. The farms produced 71.67±14.71 liters of milk on average every day, which was primarily supplied to dairy processing plants. For feeding the cows, all farms used concentrates and forage. The mean concentration of AFM1 in milk samples collected from Bakalia was higher (190.00±120.87 ng/L) than that in milk samples collected from the Khulshi (108.44±66.19 ng/L) and Pahartali (189.25±160.78 ng/L). The overall prevalence of AFM1 was 43% (N=39) of the total examined samples. A total of 69% (N=27) and 5% (N=2) of AFM1 positive samples exceeded the European Union Regulation (50 ng/L) and BSTI/BFSA regulations (500 ng/L) respectively. There was a significant difference in the occurrence of AFM1 in Bakalia regarding Khulshi and Pahartali. This research will aid in measuring the AFM1 content in raw milk and helping to address public health issues.

Paucity of knowledge on resistant variety, high yield loss ranging from 32- 57% and dearth of knowledge on management of Alternaria leaf spot has been the major concerns in radish production in the world. Our study will aid in multiplication and standardization of the germane variety of radish resistant to Alternaria leaf spot disease so as to escalate the production, productivity, and the competitiveness in the domestic as well as in the international market. Hence, this experiment was rendered to screen the radish genotypes against Alternaria leaf spot disease in Western Nepal in 2021. Seven genotypes namely Sparkle white F1 hybrid, Korean cross, Palak-patta 35, Pyuthane red, 40 days, Geeta 33, and Mino early were used as the treatment and experiment was laid out in one factorial RCBD design. Each treatment was assigned with 8 plants for observation with 3 replications per treatment. Parameters like days to appearance of disease, incidence of disease on seedling, disease severity (3 scorings), mean score of disease, mean AUDPC and reaction of genotypes were measured during the experiment. Our study unveiled highly significant result for the days to appearance of disease, disease severity, mean score of disease and AUDPC among the genotypes of radish. Alternaria leaf spot first appeared in Pyuthane red (18.33 days) while appeared late in Mino early. Disease severity was found harsh in 40 days at each scoring (57.33, 64.67 and 70.33 respectively); on the contrary severity was minor in Sparkle white at each scoring (26.67, 35 and 44.17 respectively). Similarly, the highest MDS (3.4) and AUDPC (449.8) was found in 40 days, whereas the lowest MDS (1.7) and AUDPC (246.5) was observed in Sparkle white. Ultimately, it is contended that 40 days was found to be moderately susceptible variety while other varieties were found to be moderately resistant.

Onur Sefa Alkaç | Zeliha Kayaaslan | Fulya Okatar
Growth regulators such as Indole-3-Butyric Acid (IBA) are generally used to promote root formation of rose cuttings. However, today, within the scope of sustainable agricultural practices, research studies of new materials and methods alternative to synthetic chemicals in the plant production process are gaining momentum. At the beginning of such alternative applications are plant growth-promoting rhizobacteria (PGPR) and mycorrhizal fungi, which are increasingly used today, promoting plant growth. In this study, Bacillus cereus (ZE-7), Pseudomonas putida (ZE-12) rhizobacteria and mycorrhiza (6000 ppm) were applied to 12-15 cm long softwood rose cuttings. The softwood cuttings were kept in the mycorrhiza suspension for 10 seconds and in the rhizobacteria suspension for 30 minutes and then planted in the rooting medium. In the study, in order to determine the effects of applications on steel root development; rooting rate (%), callus rate (%), decay rate (%), root number (number) and root length (cm) parameters were examined. In the results of working; the highest rooting rate (19.44%), the highest callus rate (38.89%) and the highest number of roots (8.64 units) were obtained in ZE-12 treated cuttings. In particular, rhizobacteria application showed a high effect on reducing the rate of decay in steels. The lowest decay rate in the steels was obtained from the ZE-7 bacterial strain application (8.33%) compared to the control (38.89%). As a result, it was concluded that mycorrhiza and rhizobacteria applications can be applied to rose cuttings and these applications as an alternative to IBA in rooting.
