Abstract: The field experiment was conducted at Yabello Onsite for three years; 2018, 2019 and 2023 on main cropping seasons. Six bread wheat varieties were evaluated. The trial was laid out in randomized complete block design (RCBD) with three replications. The experiment was objected to increase production and productivity of bread wheat and recommend best variety for agro-pastoralists and farmers in lowland agro-ecology and specifically to identify cultivars with better adaptability, high yielder and tolerant to drought. The combined analysis of variance showed that there was significant difference among varieties in yield and yield related traits in all cropping years. The highest grain yield was obtained from “Amibara-2” variety (3918.2 kg/ha) followed by “Fentalle-2” (3700.5 kg/ha) while the lowest grain yield was recorded from werer-2 variety (3073.8 kg/ha). The result of the experiment suggests conducting research work on adaption trials of different crop enhances production and productivity for end users. Therefore, the identified varieties were suggested for further demonstration and popularization in Borana lowland and areas with similar agro-ecology.

Abstract: In recent years, since deep learning technology have been applied to handwritten text recognition, the need for handwritten document image Datasets has been growing more and more. In particular, the development of the dataset is of great significance for improving performance of handwritten Korean text recognition because no dataset for handwritten Korean text recognition has been published. In this paper, we present the “RanPil”, a new training and performance evaluation dataset for handwritten Korean text recognition, which consists of a total of 8,600 pages of images (182,000 text lines and 4,300,000 characters) written by 1,804 people. We evaluate writing- diversity of handwritten document images, such as text line spacing, text line slope, character size, word spacing, and character compactness. In addition, we propose an MOS (Mean Opinion Score) evaluation method for the scrawl-level. Finally, we evaluate the performance of TrOCR based on vision encoder and decoder with a test dataset classified by the scrawl-levels.

Abstract: Studying spatial variations in rainfall and temperature is crucial for assessing climate-related changes and designing future water resource management strategies and agricultural planning. This study aims to analyze the climate parameters in the Amhara region of Ethiopia. Rainfall, maximum, and minimum temperatures data spanning from 1991 to 2020 were obtained from CHIRPSv2.0 and ERA5. The results showed that Amhara region had received mostly Bega, Belg, and Kiremt and annually 100-250 mm, 150-300mm, 800-1000 mm, and 1000-1300 mm rainfall, respectively. Climatologically Amhara region received a high amount of rainfall from June to September. Based on the annual rainfall cycle, Bega is the dry period over Amhara region. The results also showed that the mean maximum temperatures in Bega, Belg, Kiremt, and annually over Amhara region were 23-27°C, 27-30°C, 21-27°C, and 23-27°C, respectively. The study also revealed that minimum temperatures across Amhara ranged from 9-15°C for Bega, 12-18°C for Belg, 15-18°C for Kiremt, and 9-15°C annually. Based on these findings, we recommend that the Forecast and Early Warning, and Development Meteorology team use this recent climatology to give a seasonal climate forecast easily for various sectors to support the development of climate-resilient agricultural practices and water resource management strategies.
