{"title":"Review on Adoption of Improved Soya Bean Technologies: Empirical Evidence from Ethiopia","authors":"","doi":"10.7176/jnsr/14-6-01","DOIUrl":"https://doi.org/10.7176/jnsr/14-6-01","url":null,"abstract":"Soybean is a legume crop grown in the tropical, subtropical, and temperate climates which are used for food and animal feed. However, the production and productivity of soybean is low and improvement in production and productivity depends on the extent to which a household has applied the recommended production technologies. The review was aimed to identify the determinants of adoption and intensity of improved soybean varieties to generate information that helps to understand and evaluate the key challenges in Ethiopia. The review showed that sex of household, age of household head, education, farm experience, participation in training, and extension service affect the adoption of improved soya bean varieties positively and significantly while the distance to the nearest market affects adoption of improved soya bean varieties negatively and significantly. On the other hand, the intensity of adoption was affected by age, soya bean farm experience, participation in training, and size of livestock holding. Most of the studies reviewed in this paper indicated that sex has a significant positive impact on the adoption of improved soya bean varieties. However, the participation of female households in the adoption process indicated that 15% of female-headed households and dominated by 85% of male household heads. Therefore, to improve the adoption of modern agricultural technologies like improved soya beans the following recommendations are forwarded. Female-headed households should get emphasis in all activities of the promotion of new technologies. On the other hand, evidences showed that the huge oil factories in Ethiopia like W. A and BK are using soya bean as a major input to their production. Consequently, those industries demanding a higher amount of soya bean as an input and they are creating a backward linkage to smallholder soya bean producer farmers. For instance, W.A's edible oil factory alone needs 20,000 hectares of land to run the business and 500,000 quintals of soya bean requires per year. Therefore, it can improve smallholder farmers' livelihood by creating market opportunities to supply their products directly to factories. Thus, the promotion of new soya bean varieties, strong linkage between farmers and factories and comprehensive studies on the adoption and impact of soya bean should get attention from the regional and federal government of Ethiopia.

{"title":"Investigation of the Bioremediation Performance of Cow-dung and Wire-croton on Crude Oil Polluted Soil","authors":"","doi":"10.7176/jnsr/14-6-03","DOIUrl":"https://doi.org/10.7176/jnsr/14-6-03","url":null,"abstract":"Crude oil exploration is associated with oil spillage causing environmental degradation including loss of soil fertility and biodiversity. Various technologies are available for remediating crude oil polluted soil, but, bioremediation seems to be more environmentally friendly and cost effective. Thus, the current work is on the bioremediation of crude oil polluted soil using cow dung and wire croton leave as the amendments. It was conducted as a batch process and was monitored for 42 days (six weeks). Separate cow dung and wire croton, and different quantities of cow dung and wire croton were blended to remediate the soil. The analysis conducted included the Total Petroleum Hydrocarbon (TPH), Hydrocarbon utilizing Bacterial (HUB) and the Total Organic Carbon (TOC) content of the soil. The result shows that wire croton and cow dung have the potential to be used as bioremediation nutrients. When these nutrients were mixed at different proportions, the combination involving 30 g of cow dung and 30 g of wire croton gave the least performance in terms of HUB, TPH and TOC across the duration of the study, and the maximum was achieved using 200 g of cow dung and 200 g of wire croton as shown by over 650 thousand HUB increment, 95 % hydrocarbon degradation, and 76.3 % total organic carbon obtained. This shows that appropriate combinations of cow dung and wire croton is required to obtain a higher performance using both nutrients for remediating a crude oil polluted soil.
