Abstract: Although it has high potential crop productivity, poor internal drainage and water logging during the wet season made the vertisol difficult for crop production including haricot bean in the study area. Cognizant of this fact, this study aimed to demonstrate and evaluate the yield and yield related performance and economic feasibility of haricot bean production in vertisoil using drainage technology in the study area. Thus, a comparative demonstration and assessment local farmers vertisol management practices and 40*80 drainage technology has been done on selected eight farmers found in Abeshge district for two consecutive years. The required data for the study was collected through a participatory open-ended interview guide and focus group discussion (FGD) of representative farmers in the study area. Moreover, the economic feasibility of the technology was analyzed using partial budget analysis. The finding of the study shows that the average yield advantage of 40*80 vertisol drainage management practice over local farmers practice was 45% and 3% in the year 2021 and 2022 respectively. Moreover, farmers preference to the explicitly show that 40*80 drainage technology is more productive than the local practice. The economic feasibility assessment of the technology also depicted that the demonstrated 40*80 drainage technology is lucrative and profitable with MRR of 1670%. Thereby it’s recommended for further scaling up in similar agro-ecologies.

Abstract: As it is known that electromagnetic fields have been used for various life activities, a study was conducted to measure the electromagnetic field effect on 900 MHz head fluid replacement liquid temperature using thermocouples. This research was conducted to determine the effect and consequences of electromagnetic wave radiation on the temperature of the replacement liquid when the emitted electromagnetic field is absorbed by the replacement liquid during communication activities. J-pole antenna is used to emit electromagnetic waves as a simulation of the electromagnetic field of mobile phones. This study shows that the change in the average head fluid replacement liquid temperature is 1.43 ± 0.136°C after being exposed to a 900 MHz electromagnetic field at a level of 23 dBm, and an average temperature change of 1.46 ± 0.147°C with a field level of 33 dBm. for 10 minutes. The effect of exposure to electromagnetic fields around the head, with a certain period of time, will cause the temperature of the head fluid to increase and the electrical characteristics of the head fluid to change which can have an impact on the healthy functioning of the head.
