Aim: To examine the awareness and adoption of improved sweetpotato varieties in Ghana.

Study Design: Multi-stage sampling (Proportional Probability, Purposive and Random) of Sweetpotato farmers.

Place and Duration of Study: Improved Root and Tuber Technology Implementation Hubs. Fifteen (15) districts were selected. In each district, 5 communities and 35 sweetpotato farm households were selected from each district.  The total sample size was 525 households across the country. The average treatment methodology was used to estimate the factors influencing awareness and adoption of improved sweetpotato varieties and the effect of awareness on adoption.

Results: Awareness of improved sweetpotato varieties are significantly influenced by household size, farm experience, number of plots cultivated and membership of FBOs. The population adoption rate was 67.2%, whereas the adoption rate within the subpopulation that is aware of the improved sweetpotato varieties was 69.6%. Potential adoption among the farmers who are not aware of the improved sweetpotato varieties was 59.3% hence resulting in an adoption gap of 13.8% due to incomplete awareness.

Conclusion: Dissemination efforts should include effective awareness creation about the improved sweetpotato varieties across the country for enhanced adoption. For effective promotion and adoption of improved sweetpotato varieties in Ghana, factors such as the age of the farmers, farm experience in sweetpotato cultivation, residential status and number of plots owned by farmers need to be considered in designing appropriate strategies.

Teachers are the ultimate medium of knowledge delivery to students. They connect the students to harness the facilities available in the institution. The teaching staff of agricultural universities uniquely performs multidimensional functions than any other type of educational institutions. Similarly, their nature of work is also unique. Hence, the working environment of the teachers should be analysed periodically to create a conducive working condition. Thus, the study was conducted with the prime objective to document the constraints of the agricultural teaching scientists in teaching undergraduate agricultural students. Ex-post-facto research design was employed to document and diagnose the constraints faced by them. The scientists working in the main campus of Tamil Nadu Agricultural University, Coimbatore, India were considered as the sample for the study and the study was conducted during September 2017 to January 2018. A semi-structured questionnaire was prepared to document the constraints faced by the respondents. The study included 52 university teachers of age range from 34 to 59 comprising of 52 percent of male and 48 percent of the female. The constraints were documented through an open-ended questionnaire to state their difficulty with undergraduate teaching. Wider student-teacher ratio, poor classroom infrastructure, poor maintenance of Audio-Visual aids, immoral activities of the students, the distracted mind of the students, external intrusion with guest lectures and heterogeneity of the students were identified to be the significant constraints faced by the UG teaching staff. This paper attempts to suggest remedies for the documented constraints.

The study examined the availability, level of competence and benefits of Information and Communication Technologies (ICTs) in Agricultural development among agricultural lecturers and students in Enugu State, Nigeria. Almost all the respondents (lecturers 96.9%, students 90%) had acquired ICT trainings. All the listed ICT facilities were available to the respondents except facsimile (Lecturers 9.4%, Students 25%) and satellite technology. The respondents were competent in the use of ICTs except in the use of facsimile and satellite technology. The respondent’s lack of competence in the use of facsimile and satellite technology could be as a result of its non-availability in the faculty. On the average, students in the selected institutions are more competent in using ICT facilities than their lecturers, this could be as a result of the student’s educational demand to meet up with the requirements of the various courses they need to pass before they could become certified graduate, thus, making them to explore the various ICTs more than the lecturers. The respondents perceived ICTs to be beneficial in carrying out their work effectively, helping researchers to source more information for their work, improving research and published work, accelerating, enriching, and deepening skills, motivating and engaging students in learning and saving time. The output of this study is important because it will serve as a blueprint for agricultural libraries, information managers/information scientists, researchers, agricultural lecturers, agricultural students, and all agricultural stakeholders to chart the right course of action for the use of information and communication technologies in developing agriculture through policy formulation and implementation.

Rice is the stable food in India, improvement in efficiency levels is one of the major means of sustaining the staple food production and thereby ensuring food security. This study was taken up to determine the technical efficiency and constraints faced by the farmers in rice cultivation under different irrigation systems in Tamil Nadu. It could be concluded that the mean technical efficiency was 0.76, 0.75 and 0.71 for canal, well and tank irrigation system respectively. This showed that in the study region, the efficiency of the farmers was almost same for all the three systems of irrigation. The results of the Garrett's ranking technique indicated that non-availability of fertilizers at the appropriate time, delay in getting subsidy for drip irrigation and fertigation systems and scarcity of irrigation water were the most important constraints in rice cultivation using canal, tank and well irrigation systems. Thus, productivity can be increased by the adoption of non-monetary inputs like timely sowing, maintaining optimum plant population, timely irrigation, efficient use of fertilizers and irrigation water, need-based plant protection measures and timely harvesting of crop.

Agricultural Transformation in Bhutan: From Peasants to Entrepreneurial Farmers

Bhutanese farmers have traditionally practised integrated subsistence farming, producing crops and livestock and utilising forest products. However, they are increasingly practising entrepreneurial farming today. The study of agricultural transformation is valuable for understanding the evolution of Bhutan’s agriculture systems. Therefore, the current study reviews the five components of agriculture responsible for the transformation of Bhutanese farmers from peasants to entrepreneurial farmers: urbanisation, farm mechanisation, community institutions, high-value products and youth aspirations. Given the current rate of globalisation and improvements in agribusiness, the number of entrepreneurial farmers in Bhutan is likely to rise in the future. However, relevant stakeholders must still strive to create a conducive environment for agribusiness in Bhutan.
