The farming technique of radical terracing is one of the new agricultural technologies introduced in Rwanda to enhance farming activities in the highland areas. The study was designed to analyze the applicability of the adoption and diffusion model of farm innovation on adopting radical terraces in Rwanda. It adopted a descriptive correlational research design to the farmers owned radical terraces in Nyamagabe District. The purposive sampling technique was applied to select 19 Key Informants and 192 farmers. Both quantitative and qualitative data were collected through questionnaires, face-to-face interviews, direct observation and documentary sources. Descriptive and inferential statistics were used for quantitative data analysis whereas thematic and narratives content analyses were used on qualitative. The research outcomes show that the level of farmers' adoption was medium. Besides, the farmers’ access to agricultural information; and farmers’ participation were found to have a positive influence on the applicability of the adoption-diffusion model on the adoption of radical terraces. The study showed that the adoption of radical terraces in Nyamagabe depended on the compatibility with the existing values and practices among farmers based on the information-contagion model and the social participation model that is widely used in the agricultural context. The study recommended the government continue sensitizing farmers on the importance of adopting radical terraces for better use and maintenance as a modern farming practice. Further research should focus on the applicability of technology characteristics user's context model on the adoption of radical terraces in Rwanda.

Salinity, which is one of the abiotic stress factors, severely restricts plant production as a result of the negative effects of plants in different growth and development periods. Therefore, it is extremely important to determine the tolerance limits of plants to salinity in order to eliminate the limiting effect in terms of plant growth. Flax is an industrial plant that is used for multiple purposes and has commercial importance in the world. This research was carried out in controlled laboratory conditions in 2021 to determine the effects of salinity on the germination of flax seeds. In the study, germination rate, root length, root fresh weight, shoot length and shoot fresh weight were evaluated. The result showed that significant differences between different NaCl solutions for all evaluated characters. Although the highest value was obtained in the control group in Mures variety, the highest value was obtained in 25 nM NaCl concentration in all other characters except for the germination rate in Dakota variety. The highest germination rate of 93.3% was obtained from the control application (0 mM NaCl) in both varieties. On the other hand, there was no germination in both varieties in 200 mM application.

Pestil is one of the important foods traditionally produced in Türkiye, with high energy, vitamin and mineral content. It is obtained by naturally drying the pulp obtained from different kinds of fruits after mixing it with ingredients such as sugar and flour. In regions where the fruiting period depends on the season, fruit pulp is produced in order to benefit from it in winter. In addition, bioactive components originating from the fruit increase the nutritional value. In this study, the physicochemical and antioxidative properties of the pestil obtained from three different Hawthorn fruits (Crataegus meyeri, Crataegus turkestenica and Crataegus orientalis) known to have positive effects on health were investigated. The results revealed that, depending on the fruit type, pestil samples have high antioxidative properties (IC50: 50.11±0.16-52.1±2.14 mg/mL) due to the high phenol content (39.8±0.16-52.95±1.21 mg GA/g DW). In this context, in the present study, it has been seen that the pestil prepared with the traditional method from three different Hawthorn fruits should be industrially produced as a product for people to access healthy and various foods today.

This study was conducted to evaluate essential oils from Croton macrostachyus Hochst. ex Delile, Eucalyptus globulus Labill., Allium sativum L., Cymbopogon citratus (DC.) Stapf, Cymbopogon martini (Roxb.) W.Watson, Rosmarinus officinalis L. and Thymus schimperi Ronniger using four concentrations (l mL, 2 mL, 3 mL, 4 mL) and three sprays against potato (Solanum tuberosum L.) late blight disease. Two improved potato varieties were planted using randomized complete block design with factorial combinations in three replications. Analysis of disease incidence means at 53 and 60 days after planting showed highly significant differences between varieties and among sources of essential oils. Furthermore, the combined effect of essential oils and potato varieties on disease severity showed significant differences. Disease severity was maintained from 25% to 48% (Jalene); 13% to 30% (Gudene) with essential oils while it was maintained between 92% and 95% (Jalene); 37% to 38% (Gudene) for control plants. The lowest disease percentage of disease severity was obtained on plants treated with A. sativum for Jalene variety while on plants sprayed with C. macrostachyus, E. globulus and T. schimperi for Gudene variety. The lowest disease progress rate 0.198/day and 0.162/day as well as values of area under disease progress curve 228% days and 93% days were obtained for varieties Jalene and Gudene, respectively. Maximum reduction in mean disease severity was exhibited by garlic for varieties Jalene (28.3%) and Gudene (16.3%), as compared to the control (93.3% for Jalene and 37.5% for Gudene). Therefore, results indicated the potentials of essential oils to minimize effects of potato late blight disease. Communities involved in potato production could use the current results as base line information to find alternative management options for late blight disease which has no effect on human health and environment. However, further investigation is required on essential oils affordability and availability to farmers across different locations.

Broiler production supplements income of smallholder farm households. Profitability and productivity and analysis are important considerations in measuring efficiency or performance of a farm business; hence, improved output and income are not only a function of increase in the scale of production, but also how efficiently the resources are being utilized. This study therefore estimates the profitability and level of productivity among broiler farmers in Jos North, Plateau State, Nigeria. Multistage sampling technique was employed to select respondents for this study. Primary data collected were analysed using descriptive statistics, farm budgeting model and Total Factor Productivity (TFP) analysis. The study revealed that the net farm income of broiler production was ₦96,900/flock size; suggesting a relatively profitable venture with prospects for improved economic potentials. The estimated percentage profit margin was 45.6%; indicative of the percentage net margin accruable to the farmer from the estimated gross margin and benefit-cost ratio was 0.84. Furthermore, most (54.3%) of broiler farmers were sub-optimally productive as their TFP indices were below the optimal scale; attributable to sub-efficient input mix and cost of production inputs. In addition, constraints of broiler production in the study area included the following; high cost of feeds (92.9); high cost of chicks (85.7%); financial constraints (80%); high cost of poultry equipment (55.7%); high cost of medication (35.7); disease outbreak (28.6%) and inefficient market system (21.4%). Improving access to and subsidy of poultry feeds, chicks, production inputs and credit, extension, medical services and cooperative formation for market linkages are strongly recommended.

Climate change is one of the biggest global environmental problems faced by mankind in recent times. Therefore, determining the knowledge and awareness levels of individuals on this issue is very important in terms of contributing to the solutions to be developed in the fight against climate change at the local level. In this study, it is aimed to determine the approaches, consciousness and awareness levels of Kırşehir Ahi Evran University students and local people about climate change in Kırşehir. The main material of the research consisted of primary data obtained from 250 face-to-face surveys applied to students and the public. Related literatures are also secondary data. The survey questions include questions about the individual characteristics of the person (gender, age, education level, job), climate change awareness level, and the effects of climate change on agriculture and water resources. The obtained data were analyzed using SPSS 26.0 statistical package program. In the evaluation of the data, descriptive statistics, frequency tables and graphical representations were used. As a result of the analyzes performed using the Kruskall-Wallis test, it is seen that there are statistically significant differences between the education groups in the variables of climate change awareness level and climate change risk perception level (P0.05), and there was a statistically significant difference between the occupational group averages in the climate change risk perception level (P
