Genetic Variability and Association of Yield and Yield-Related Traits under Moisture Stress in Common Bean Genotypes (Phaseolus vulgaris L.) at Melkassa and Miesso, Ethiopia

Twenty-five common bean genotypes were evaluated to assess the genetic variability, trait association, and determine the direct and indirect effects of traits on seed yield. The genotypes were grown in a lattice design at the research farm of the Melkassa Agricultural Research Center, Melkassa and Miesso, in the 2018 cropping season. Analysis of variance revealed that significant differences were observed among the genotypes at individual locations. The phenotypic coefficient of variation values were moderate for number of nodes, seeds per pod, plant height, and hundred seed weight at Melkassa. Moderate genotypic coefficient of variation values were obtained for pods per plant and seeds per pod. At Miesso, moderate phenotypic coefficients of variation values were recorded for number of nodes, hundred seed weight, and plant height. High heritability estimates were obtained for seed yield and hundred seed weight at Melkassa and for seed yield at Miesso, indicating that selection could be fairly easy and improvement is possible using these traits in a common bean breeding program. High genetic advances were obtained for seed yield and pods per plant at Melkassa, while moderate genetic advances as a percent of the mean were attained for plant height, hundred seed weight, and seeds per pod. Similarly, at Miesso, high and moderate genetic advances as percent of mean values were obtained for seed yield and hundred seed weight, respectively. Seed yield showed positive and significant phenotypic association with days to flowering, internode length, and pods per plant at Melkassa and had positive and significant phenotypic association with seeds per pod and hundred seed weight at Miesso. Hence, selection of those genotypes based on the traits with high genotypic coefficient of variability, heritability, genetic advance, and positive correlation coefficient and direct effect on seed yield can be recommended for further yield improvement at the respective location and at the national level in general.

Effect of Seed Priming Methods on Seed Quality of Okra (Abelmoschus esculentus (L.) Moench) Genotypes

Seed priming is an effective way of promoting seed germination and vigor of okra by alleviating seed dormancy in fresh or stored okra seeds. An experiment was carried out to evaluate the effect of seed priming treatment on seed physiological quality of okra genotypes. This experiment was conducted in a laboratory at Haramaya University in a completely randomized design with 4 replications. It comprised of 5 seed priming treatments (untreated seeds, tape water, 200 ppm GA3, 0.5% KH2PO4, and 50% cow urine) and 5 okra genotypes (Clemson, Arka Anamika, SOH701, 240207, and 240586). The results showed that the main and interaction effects of seed priming treatment and genotypes significantly affected physiological seed quality attributes and hard seed percentage. GA3-treated genotype Clemson showed the highest germination (78.28%) and germination speed (25.29). Similarly, GA3-treated genotypes SHO701 and 240586 had the highest seed vigor index I (13.161) and vigor index II (34.14), respectively. There were no hard seeds in genotype Clemson treated with GA3 and cow urine, genotype SOH701 treated with GA3, besides genotype 240207 treated with KH2PO4 and tap water. All seed priming treatments had a significant positive effect on physiological quality and seed overcame seed hardness in all 5 okra genotypes compared to controls. Therefore, in this study concluded that GA3 seed priming treatment improved physiological seed quality, and alleviated seeds hardness in okra genotypes. As an alternative to GA3 seed priming treatments, Ethiopian farmers can also use tape water, cow urine, and KH2PO4 seed priming treatments.

Analysis of Determinants of Economic Efficiency in Honey Production in Horo Guduru Zone, Ethiopia: Stochastic Dual Cost Frontier Model Approach

Honey production is generating employment and source of income in the rural area of Ethiopia. However, its productivity was low. The objective of this study was to measure the economic efficiency of honey production in Ethiopia’s Horo Guduru Wollega Zone and their limiting factors. To achieve the above-mentioned objective, the study employed a survey methodology using a structured questionnaire tool, and the data were collected from 396 households. Both descriptive and econometric data analysis methods are employed. Dual cost was used to measure the levels of economic efficiency and the Tobit model to identify the determinants of economic efficiency in the study area. In this regard, the analysis relied on a cross-sectional data collected from 396 sample farm households. The mean economic efficiency was 44%. This demonstrates that the farmers in the study area have to decrease production cost by 56% to achieve 100% economic efficiency level. From the determinants of economic efficiency family size, extension services, training, beekeeping experience, and family size are significant technical efficiency variables for honey producers. The study suggests policies to address economic inefficiencies by increasing the number of hives, extending the best performers’ experience by increasing the frequency of extension contacts on honey production, facilitating and expanding credit service in the study area, making bee forage access simple, and increasing forest coverage on the land area in line with the current policy of Ethiopia. Additionally, since farmers in the study area spend their time guarding the honey from damage by ants and monkeys, labor that utilizes technology must be made available in the study area.

Utilization of Organic Fertilizer in Ghana: Implications for Crop Performance and Commercialization

Organic fertilizer commercialization may present a great opportunity to help deal with the issue of solid waste management and help improve the declining soil problems in many developing countries. Ghana’s solid waste is predominantly organic, which is suitable for organic fertilizer production. This paper seeks to establish relationship between organic fertilizer usage and crop farm performance and assess its commercialization potential. The study employed a farmer-survey and key informant interviews to generate data from 300 farmers randomly selected across three regions in Ghana. The computed organic fertilizer use rate is 42% among farmers surveyed, and organic fertilizer is primarily used in vegetable and maize production. The estimated current demand for organic fertilizer is about 0.7 million t/annum with a potential to rise to about 2.7 million t/annum in the long term. This will however require sensitization on its importance, availability, and affordability. The study has established a strong relationship between organic fertilizer adoption and farm performance increasing yield by 57%, income by 53%, and gross margins by 63%. There is obviously a cost reduction when organic fertilizer is adopted. Organic fertilizer adoption was found to be mainly related to farmer base organization membership status, access to extension services, access to organic fertilizer, and transport cost. Organic fertilizer commercialization has the potential to make Ghana a net exporter of fertilizer and create sustainable jobs for the youth. We recommend the use of organic fertilizer by farmers and highly recommend the commercial production of organic fertilizer.

Effect of Interrow Spacings on Growth, Yield, and Yield Components of Common Bean (Phaseolus vulgaris L.) Varieties in the Central Rift Valley of Ethiopia

The common bean is the crop used as food, feed, and to improve soil fertility. However, the production and productivity were affected by poor nutrition and fertilizer management, inappropriate interrow spacings, and the poor genetic makeup of the crops in Ethiopia. Hence, a study was conducted in two research stations at Arsi Negele and Melkasa Agricultural Research Center (MARC), during 2019 cropping season. The treatments consisted of three interrow spacings (30 cm, 40 cm, and 50 cm) and three common bean varieties (Dame, SER-119, and KAT-B9) combined in a factorial arrangement laid out in the field using (randomized complete block design) RCBD with three replications. Data on growth and yield parameters obtained were subjected to analysis of variance. Regarding the interaction effect, leaf area, number of seed pods−1, and grain yield were significantly influenced by the interrow spacings and common bean varieties at both locations. Plant height, number of pods plant−1, total dry biomass, leaf area index, hundred seed weight, and harvest index were significantly influenced by the interrow spacings and common bean varieties at Arsi Negele, whereas they were nonsignificant for MARC. In this study, the highest grain yields (2.23 and 2.17 tons/ha) were obtained from narrow interrow spacings (30 and 40 cm) combined with variety SER-119 at both locations. Hence, the highest net benefits (30848.7 and 29970.4 ETB) were obtained from SER-119 (30 cm × 10 cm, and 40 cm × 10 cm) at Arsi Negele and MARC, respectively. It was recommended that the narrow (30 cm) interrow spacing be used with variety SER-119 for common bean production in the study areas and similar agro-ecologies. On the other hand, the use of wider interrow spacings (40 cm or 50 cm) had a significant importance in improving hundred seed weight, seed quality, and disease incidences of common bean varieties at the given studied sites.

Effect of Zinc Oxide Nanoparticles in Drinking Water on Growth Rate, Biochemical Parameters, and Intestinal Histology of Broilers

The study objectives were to evaluate effects of zinc oxide nanoparticles (ZnO NPs) on growth rate, gut histomorphology, and physiological parameters of broilers. A total 360 birds were randomly assigned into five groups (n = 72 birds per group; four replicates per group n = 18), the control group drink water without nano zinc, and ZnO NP groups added 6, 8, 10, and 12 mg/liter to drinking water. The results presented that ZnO NP groups showed significant () in growth performance with reduced feed intake in all ZnO NP groups in comparison to the control at 35 and 42 days of age. Villus height and villi to crypt ratio showed significant differences (p<0.05) in all ZnO NP groups compared to the basal control, but the results showed there was no significant difference (p<0.05) between the ZnO NP and control in crypt depth. There was no significant effect of ZnO NP on total protein and albumin in broiler serum compared to the control at 35 and 42 days of age. The data showed that ZnO NP had a positive effect and improved the ratio of serum globulin and globulin to albumin compared to the others of broilers at 35 and 42 days of age. On the other hand, liver enzyme activity was significantly () different in ZnO NP groups compared to the basal control. The inclusion of ZnO NPs in drinking water significantly improved growth performance and gut histomorphology, and it had an impact on antioxidant and biochemical parameters.
