Assessing emerging beef farmers participation in high-value market and its impact on cattle sales in South Africa
Get PDFThe participation of emerging farmers in high-value agricultural markets in South Africa cannot be over-emphasized. It is one of the objectives of the government to assist emerging farmers with the necessary resources and programmes to enable them to meet the requirements and participate in high-value markets. The study investigated the impact of participation in the high-value market on cattle production (cattle sold). A systematic random probabilistic sampling technique was used to obtain a sample of 55 emerging beef farmers. Interviews were undertaken using questionnaires to collect data. Descriptive statistics and econometric methods such as Tobit model and a treatment effect model using propensity score matching estimator were employed for the data analysis. The results of binary logit regression from the PSM revealed that participation in a high-value market was significantly affected by age, household size, years of farming and difficulty accessing a high-value market. The average treatment effect of the treated showed a negative impact and decreases the number of cattle sold by 58%. The recommendations informed by the findings from the study are that youth in the study area should be involved in beef farming, appropriate training should be given to the farmers and farmer\u27s advisor should motivate farmers to sell more cattle and participate in a high-value market, and educate them about the requirements to participate in the high value markets. The DARD lease assistance should continue and include the lease of more land.

Farmers’ choice of varieties and demand for improved cassava stems in Nigeria
Get PDFIn this study, we used a household level survey to assess choices of varieties and demand for improved cassava varieties. A multivariate probit model was used to examine the determinants of choice decisions of the farmers for different varieties preventing potential endogeneity and measurement error. A Linearized Almost Ideal Demand System (LA/AIDS) model was used to analyze the demand system for improved cassava varieties. The results of the (LA/AIDS) model indicated farmers were very price sensitive to changes in improved stem prices and incomes. We suggest that intervention program that will improve the purchasing power of the farmers should be targeted towards the smallholder cassava farmers to accelerate adoption of improved cassava varieties.

Impact of industry on agricultural development in Sylhet region of Bangladesh: Farmer’s perception
Get PDFThe study targets at farmer’s perception and their cognition how they conceive that agricultural performance has been affected and devastated through industrial work. It reviews and investigates the opinion of 25% farmers of two villages from each upazila of two named Madhapur and Habiganj sadar upazila in Sylhet division where Charu Ceramic Industry Limited and Olipur industry are located respectively from mid-September to mid-October, 2021 through survey of questionnaire, interview and group discussion. According to 85% farmers, the industry shades agriculture by imposing an adverse and toxic impact on agricultural exposure and development. Among them, (41.6% and 48.4%) of farmers realize that the industry creates high propensity of losing standard quality of soil and water, respectively. They (40.2%) notice that invasion of several dangerous insects on crops has become prominent and unmanageable near the industrial area. The study represents such kind of realization of farmers to show a salient feature in view of their finding causes and intuition with significant numerical data.

On-farm demonstration of improved faba bean varieties in bale and west arsi zones, southeastern oromiya, Ethiopia
Get PDFOn-farm demonstration of improved faba bean varieties was conducted in Adaba and Dodola districts of West Arsi Zone and Sinana, Goba and Agarfa of Bale Zone. The main objective of the study was to demonstrate and evaluate recently released Aloshe variety along with standard check. The demonstration was under taken on single plot of 10m x 10m area for each variety with the spacing of 40 cm between rows and recommended seed rate of 180 kg ha-1 and fertilizer rate of 100 qt ha-1 NPS. Mini-field day involving different stakeholders was organized at each respective site. Yield data per plot was recorded and analysed using descriptive statistics, while farmers’ preference to the demonstrated varieties was identified using focused group discussion and summarized using pair wise and simple ranking methods. The demonstration result revealed that Aloshe variety performed better than the standard check of Mosisa variety with an average yield of 35.97 qt ha-1, while that of the standard check was 28.50 qt ha-1. Aloshe variety had 26.21% yield advantage over the standard check. This variety was selected by farmers in Adaba, Dodola and Agarfa. Thus, Aloshe variety was recommended for further scaling up in the area it was selected.

Adaptability study of Cowpea [Vigna unguiculata (L) Walp.] varieties in Pastoral areas of South Omo Zone, Southern Ethiopia
Get PDFField experiments were conducted on pastoral and agro-pastoral areas of South Omo Zone at Dasenech, Hammer and Gynagatom woredas of South Omo Zone, Southern Ethiopia on four cowpea [Vigna unguiculata (L) Walp.] varieties in 2019 under irrigation. The objective of the study was to select the best performing cowpea varieties in the target areas. The cowpea varieties included in the field experiment were (Black eye bean, Bole, TVU, and Kankeit). The experiments were carried out using a randomized complete block design (RCBD) with three replications. The combined analysis of variance results depicted that there were significant differences among the varieties for all the studied parameters except the number of seeds per pod. The mean values for plant height ranged from 84.89 (cm) for the variety Bole to 120.67 (cm) for TVU. The mean values for the number of pods per plant ranged from 24.33 for the variety Bole to 46.90 for TVU. The mean value for 100 seeds weight was maximum (21.11g) for the cowpea variety black eye bean and, while it was minimum (17.11 g) for the variety TVU. The highest overall mean grain yield of 2457.0 kg ha-1 was recorded for the variety Kankeit while the minimum 1695.3 kg ha-1 was noted for the cowpea variety black eye bean. Therefore, the variety Kankeit and TVU could be recommended for the study areas however further research should be done to put the recommendation on a strong basis.

Global reference seismological data sets: multimode surface wave dispersion
No full textInternational audienceGlobal variations in the propagation of fundamental-mode and overtone surface waves provide unique constraints on the low-frequency source properties and structure of the Earth's upper mantle, transition zone and mid mantle. We construct a reference data set of multimode dispersion measurements by reconciling large and diverse catalogues of Love-wave (49.65 million) and Rayleigh-wave dispersion (177.66 million) from eight groups worldwide. The reference data set summarizes measurements of dispersion of fundamental-mode surface waves and up to six overtone branches from 44 871 earthquakes recorded on 12 222 globally distributed seismographic stations. Dispersion curves are specified at a set of reference periods between 25 and 250 s to determine propagation-phase anomalies with respect to a reference Earth model. Our procedures for reconciling data sets include: (1) controlling quality and salvaging missing metadata; (2) identifying discrepant measurements and reasons for discrepancies; (3) equalizing geographic coverage by constructing summary rays for travel-time observations and (4) constructing phase velocity maps at various wavelengths with combination of data types to evaluate inter-dataset consistency. We retrieved missing station and earthquake metadata in several legacy compilations and codified scalable formats to facilitate reproducibility, easy storage and fast input/output on high-performance-computing systems. Outliers can be attributed to cycle skipping, station polarity issues or overtone interference at specific epicentral distances. By assessing inter-dataset consistency across similar paths, we empirically quantified uncertainties in traveltime measurements. More than 95 per cent measurements of fundamental-mode dispersion are internally consistent, but agreement deteriorates for overtones especially branches 5 and 6. Systematic discrepancies between raw phase anomalie
