A multi-stage sampling procedure was adopted to select 220 respondents across the study area. Structured interview schedule was used to elicit information. Data were summarised with percentages, mean and standard deviation, while factor analysis was used to categorise and isolate the gender specific factors influencing migrants’ livelihood choice. Results revealed that 51.4 percent of the migrants were male and 48.6 percent were female with mean ages of 44.6 ± 13.3 and 42.0 ± 13.3 years, respectively. The mean annual income for male and female were 459,769.91 ± 409,365.69 Naira and 247,607.48 ± 207,169.69 Naira, respectively. On-farm livelihood category was the most popular choice of both male (100.0%) and female (93.5%) while more female (50.5 and 38.3%) than male (38.1 and 28.6%) engaged in off-farm and non-farm categories respectively. For the male, five crucial factors (socio-economic status, labour resource, financial accessibility, external orientation and farm holding) were isolated with a total explained variation of 74.4 percent, whereas financial resource, labour resource, socio-economic and group benefit factors were among the six factors (with explained variation of 72.1%) found to influence livelihood choice of female migrants. These findings revealed gender-based differentiation in the factor influencing the choices of male and female migrants. These factors were major determinants of livelihood choice of migrants. Therefore, focusing on gender-specific factors influencing the livelihood choice of migrants is crucial to any planned intervention to enhance cocoa production in the study area.","PeriodicalId":14890,"journal":{"name":"Journal of Agricultural Science and Practice","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88530041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was carried out in a randomized complete block design (RCBD) with four replications. The treatment comprised different rates of poultry manure viz; 0 (control), 5, 10, 15 and 20 t ha-1. The growth and yield parameters investigated were vine length, number of branches per plant, number of leaves per plant, leaf area index, number of fruits per plant, fruit yield per plant and fruit yield per hectare. The data collected on growth and yield parameters were subjected to analysis of variance (ANOVA) and treatment means were separated using Fisher's least significant difference (F-LSD) at 5% level of probability. Gross margin (GM) as well Return on Investment (RoI) was calculated to determine the profitability. The results showed that poultry manure significantly (p<0.05) induced higher vine length, number of branches per plant, number of leaves per plant, leave area index, number of fruits per plant, fruit yield per plant and fruit yield per hectare compared to control (0 t/ha) with optimum values obtained in 20 t ha-1. The profitability of the use of poultry manure increased with increase in the rate of poultry manure. The highest gross margin (N 3,233,860) was obtained from 20 t ha-1 of poultry manure followed by 15 t ha-1 (N 2,021,020), 10 t ha-1 (N 1,381,748), 5 t ha-1 (N 588,300) and 0 t ha-1(N14,660). Similarly, the highest RoI was obtained in 20 t ha-1 of poultry manure (325.95%) followed by 15 t ha-1 (237.49%); 10 t ha-1 (185%); 5 t ha-1 (93%) and the lowest was in 0 t ha-1 (2.76%). It could be concluded from the study that the use of poultry manure for cucumber production in Iwollo is profitable and most profitable when 20 t ha-1 is used.","PeriodicalId":14890,"journal":{"name":"Journal of Agricultural Science and Practice","volume":"2018 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84129080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an annual herbaceous plant that belongs to the oxalate-rich food group. Oxalate is a naturally occurring plant metabolite that is present in all plant-derived human diets. The accumulation of oxalate by crops and pasture plants has a negative impact on the nutritional quality of foods and feeds. Oxalate is a poisonous organic acid that has a significant impact on the eating quality. Acridity causes swelling of the mouth and throat. Oxalate-rich foods also reduce calcium bioavailability and increase the risk of kidney stones. About 75% of all kidney stones are made up primarily of calcium oxalate. Chronic kidney disease affects 10% of the global population, and over two million people currently receive dialysis or a kidney transplant. Oxalates in food can be reduced through physical processes, chemical treatments, and genetic improvements. Cooking root crops may improve digestibility, palatability, storage quality, and safety. Boiling significantly reduced the amount of anti-nutritional factors, resulting in higher food quality. Eating high-calcium foods and adding calcium to cooking are two other ways to reduce oxalates in the diet. Calcium salts are widely accepted and used as acidity regulators, firming agents, and stabilizers in processed foods. Taro corms' total soluble oxalate content also decreased during storage. Explicitly, genetic advancements can aid in the development of long-term solutions. The purpose of this paper was to investigate acridity, its health and economic consequences, and potential food-acridity-reduction mechanisms. This educates users about the dangers of oxalate and aids in the development of mitigation strategies.","PeriodicalId":14890,"journal":{"name":"Journal of Agricultural Science and Practice","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79392993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parent AND277 donor of Phg-1 and Co-14 genes for ALS and ANT respectively and the recipient KT-ABC001 line was used for this experiment. In genotypic selection, SSR and SCAR marker were used. Marker assisted backcrossing procedure was adopted and inheritances for resistant genes were characterized by using F2 and backcrosses. The Chi-square values showed no significant differences for ALS and ANT, 0.05 (p<0.78) and 0.03 (p<0.9) in genotypic and phenotypic selection respectively. The narrow sense heritability for ALS and ANT were 0.97 and 0.95 implying that selection for ALS and ANT can be done at early stage in a segregating population. Correlation values for ALS (r = -0.65) and for ANT (r = -0.73) were obtained between phenotypic and molecular data respectively. Eight gene pyramid groups were developed and evaluated against ALS and ANT. The gene pyramid group means were significantly different from each other (p<0.01) of which, Phg1+phg2+co14+cbb qtl and Phg-1+co-14+cbb QTL exhibited the lowest mean disease score to the three pathogens indicating both a high degree and a broad spectrum of resistance.

There is an increasing demand by farmers for production and consumption of improved OFSP varieties in the study areas. In order to respond to farmer requests, participatory variety selection trial was conducted with the objective of selecting superior OFSP varieties with farmer’s preferred traits. The trial was conducted during 2019 and 2020 growing seasons across three sites in Gedeb district of Gedeo Zone. Six varieties, including one old OFSP variety as a check were tested in a mother trial using each site as a single replication. For a baby trial, one new and one old variety was given to more than 30 model farmers around each site. Data were collected on agronomic traits such as root yield, above ground biomass, harvest index and sweet potato virus disease from the mother trial and analysis of variance was conducted. The combined analysis showed the presence of significant differences (p≤0.05) among tested genotypes for observed traits. The highest root yield was recorded for Dilla (23.11 t/ha), followed by Alamura (22.57 t/ha), Kabode (18.66 t/ha) and NASPOT-13 which produced the lowest root yield of 12.10 t/ha as compared to the others. Demonstrations of various sweet potato based foods were also made and 18 farmers (13 male and 5 female) were invited for variety assessment and selection based on the recipes. These farmers set sensorial attributes like flavor, taste, texture, and hardness of the cooked roots for taste-tests. Considering overall ranking of the six parameters (taste-tests) and agronomic traits such as root yield, above ground biomass, resistance to virus disease, varieties Dilla, Alamura, and Kabode were selected as the 1st, 2nd and 3rd choices, respectively. Therefore, scaling up of these OFSP varieties should be done in the study area and areas with similar agroecologies in order to alleviate the problems related with VAD.","PeriodicalId":14890,"journal":{"name":"Journal of Agricultural Science and Practice","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81672237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of the descriptive statistics show that the average age, level of education, number of household members participating in maize production of the farmers were 44 years, 7 years and 9, respectively. The outcome of the multiple regression analysis established that maize supply is directly and significantly responsive to quantity of maize output sold (proxy for market participation) (0.956) and technical efficiency of farmers (739.29) at (p<0.01) of probability. Other significant variables were age (61.653), level of formal education (114.074) and years of farming experience, which were significant at different levels (p<0.05, p<0.01 and p<0.01, respectively). In conclusion, maize supply is directly and significantly responsive to market participation and technical efficiency of farmers.

The aim of the study was to determine cheka-residue as an economic source of energy feed to replace wheat bran through evaluating its effect on weight gain and nutrient digestibility. Twenty intact yearling woyto-guji bucks selected from Baide CBBP association were divided in to five treatment groups each having four animal units. They were assigned to five experimental feeds [(Group-1/T1= Grazing + 1.8 L cheka-residue; Group-2/T2= Grazing + 0.6 L cheka-residue + 132 g wheat bran; Group-3/T3= Grazing + 1.2 L cheka-residue + 68 g wheat bran; Group-4/T4= Grazing + 200 g wheat bran; Group-5/T5= Grazing only) in a completely block design.

The average daily gain of goats maintained with T1 and T4 were significantly higher (p<0.05) than those of other treatments. Animals that received T1 and T4 had higher (p<0.05) total dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber digestibility than in the remaining dietary treatments with T4 recording the highest value of 80.6% which was 12.81% higher than control. However, the two treatments (T1 and T4) were not different both in weight gain and nutrient digestibility reflecting that one can be used on place of the other. Besides, goats attained slaughter weight in a range of 29.9 to 31.8 kg as compared to 26.8 kg weight recorded for goats managed as control. Cheka-residue supplementation in current experiment provides more profit than others.

A total of 22 scale insect species belonging to four families, namely Diaspididae (armoured scales), Coccidae (soft scales), Pseudococcidae (mealybugs), and Monophlebidae (giant mealybugs) were found infesting citrus trees in the two regions surveyed. Among the scale insects reported, four species were newly introduced in Kenya; three armoured scales Parlatoria ziziphi (Lucas), Parlatoria pergandii (Comstock), Aonidiella comperei (McKenzie), and a soft scale, Pulvinaria polygonata (Cockerell). The scale insects were closely associated with predators (coccinellids and lacewings) and attendant ants. This information will be helpful in the development of efficient management strategies against the scale insect pests, thus improving citrus production in Kenya. The scale insect pests identified in this study will be useful to plant quarantine facilities in Kenya to help to prevent and detect accidental introductions of exotic scale insect species.","PeriodicalId":14890,"journal":{"name":"Journal of Agricultural Science and Practice","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73181267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
