Abstract: Pulses are an important part of vegetarians' diets because the other foods they eat don't include much protein, and they are the main sources of various minerals, such as calcium, iron, phosphorus, and protein. The majority of the time, pulses are eaten as dehulled splits. The pulse processing is still restricted to time-consuming, health-harming, gender-biased traditional methods that assign all food preparation and processing duties to women. Despite Ethiopia's status as one of the world's leading producers of pulses, low post-harvest technological availability resulted in lower productivity and output. The machine was tested and evaluated in terms of splitting capacity, splitting efficiencies, mechanical damage percentage, and cleaning efficiency for pulse crops like Faba bean, Pea, and Lentil. The experimental design was carried out as a split-plot design having drum speeds with three levels in main plots and feeding rates with two levels in sub-plots, and the analysis was made using the R software. The experimental results clearly demonstrated that disc speed and feed rate are the most critical parameters influencing splitting capacity, splitting efficiency, cleaning efficiency, and grain breakage across Faba bean, pea, and lentil crops. Splitting capacity increased consistently with both drum speed and feed rate, with maximum throughput achieved at the highest speed (650rpm) and feed rate (8 kg/min). Splitting efficiency improved with increasing drum speed but declined slightly at higher feed rates, indicating that while throughput rises, efficiency may be compromised under heavy loads. Cleaning efficiency was highest at high drum speeds and moderate feed rates, confirming that excessive feed rates reduce the effectiveness of impurity separation. Breakage percentage increased with drum speed but decreased with higher feed rates, showing that high speeds intensify mechanical stress while higher feed rates provide a cushioning effect that reduces kernel damage.

Abstract: The survey was conducted with the objective of assessing and identifying the major problem and constraint on water lifting pump for irrigation purpose. The assessment result identifies technical pump problem facing the farmer on the field. From the result, eagle and koshin type pump were easily and frequently damaged after purchased. Cylinder gasket and pump impeller damage were the two main problem of those pump. Those eagle and koshin pump were mix the fuel and oil which was cause of pump stop and lead to pump damage. Spark ignition plug was the other pump problem from the survey result. Due to this spark ignition problem the pump was not running smoothly and with optimum noise which leads to decrease and damage engine efficiency and performance. The survey results also indicate that, getting of best pump with long life-span was the main pump problem facing the farmers. The result shown that, Honda pump was very preferred by farmers because of its not easily damage and its long durability. The result shown that 96.3% of total sample response as there was no organization support on access, maintenance and filling technical gap of using water pump. From the result the farmer needs organization support on getting best pump, information, capacity building and filling technical gap on using of pump. The result indicates that, the farmers facing economic crise from expensive to very expensive cost of pump maintenance. All stakeholder and government should facilitate and monitor on access and maintenance of small holder water pump. The farmers should follow the recommended guidance on using of water pump especially on operation and oil change time. The farmers should get information from field of specialization and expert when purchasing the pump. The government should solve maintenance problem of pump by facilitating and employing technician at agricultural office.
