8Background: Agroforestry is a kind of land use system that has been practiced since long in many parts of the world. Even if agroforestry is contributing a lot for the farmers, no study has been conducted which acknowledges the socio-economic importance of agroforestry practices in Harari regional state. Therefore, this may create a problem to expand and adapt the practices to another area for the cope and mitigate climate changes and achieve food security. Methods: The study used descriptive statistics to analyze the data. It ascertained the role of agroforestry practices in Harari regional state. A sample of 350 farmers was interviewed and selected using two-stage random sampling techniques. Result: The results showed that 100% of the sample respondents practiced agroforestry as a land use for income source, shade, soil improvement, fodder, firewood, construction material, medicinal purposes etc. The components of the agroforestry system adopted by the local community were pulse, root, cereal crops and vegetables. Khat, Eritia, Acacia, Cordial, Zeziphus were the fodder species used. 78.57% of the respondents used a stallfeeding technique to feed their animals. The respondents obtained annual income of 32,199.16 Ethiopian birrs on average. In general, the agroforestry system helps the local communities to diversify their income, fulfill animal feed and cope with and mitigate climate change. To sustain the local people with the climate change, decision-makers and researchers should give more attention to the preferred agroforestry species. [ABSTRACT FROM AUTHOR]

Background: Drought stress poses a significant challenge to agricultural productivity, particularly in regions with limited water availability. Maize, a staple crop worldwide, is highly susceptible to drought stress, leading to reduced seed germination, stunted growth and ultimately diminished yields. Addressing this issue, in this study various phytohormones and polyamines were used as priming agents for seeds to evaluate its performance to mitigate drought stress in maize seed germination and vigour. It plays crucial roles in regulating plant growth and development, as well as responses to various environmental stresses, including drought. These hormones modulate physiological and biochemical processes, leading to adaptive changes that helps maize plants to cope with water scarcity. Methods: The experiment was conducted by exposing maize seeds primed with different phytohormones and polyamines in optimum along with non primed seeds (control) to various levels of PEG concentration ranging from -0.2 MPa to -1.0 MPa for creating drought stress. Primed seeds subjected to a germination test. The seedling growth parameters and seed vigour were evaluated to analyse better performing seed priming treatment to mitigate drought stress. Result: From the experiment it is concluded that increase in concentration of PEG (from -0.2 Mpa to -1.0 MPa) decreased the seed germination and seed vigour traits in maize. Among seed priming treatments, seeds primed with melatonin 150 μM showed greater performance seedling vigour and its related traits even under water deficit stress condition. In conclusion, seed priming with melatonin exhibited superior efficacy in mitigating drought stress in maize. This finding highlights the potential of melatonin as a promising seed priming agent for enhancing drought tolerance in maize seeds. As seed priming is simple, easy and cost effective method, farmers can use this technology as one of their practice to eliminate the effect of drought stress in maize crop. [ABSTRACT FROM AUTHOR]
