Acha (Digitaria sp) is a powerhouse of nutrient, filling, versatile, light, and delicious, yet the most underutilized food security crop in Nigeria. The value of the nutritional content (amino acids, protein, starch, crude fibre and ash) present in acha grain is higher than that reported for other cereals such as rice, maize and sorghum and as such, a panacea for malnutrition’. The grain is tolerated by even those with frail digestive systems, including small children, the elderly, and those who are health-conscious. More so, it is a very fast-growing cereal grain and it is considerably cheaper than most staple food crops. Acha is said to be a good food security crop as it blends well with other recipes. It has a texture similar to grits or couscous with a sand colour and due to the primitive conventional processing methods, it contains a load of gritty sand particles. These gritty sand particles can be prevented by threshing over a clean, hard, non-sandy surface. The consumption of acha daily brings you back to the prehistoric era of longevity and wellness.

The present study was conducted at Experimental Sennuris District in Fayoum Governorate, Egypt (latitude of 29024/26//N and longitude of 30052/00//E) to investigate the effect of harvest dates on some sugar beet varieties concerning their yield and quality. Two successive field experiments were carried out in the 2020/2021 and 2021/2022. A randomized complete block split plots were assigned for the four harvesting dates (mid-February, 1st week of March, mid-March and 1st week of April), i.e. at the age of 180, 195, 210 and 225 days after sowing. The sub-plots were occupied by the four sugar beet varieties i.e. (Faraida, Jampol, Fantazja and Melodia). The obtained results revealed that there were significant differences among the four studied harvesting dates concerning root length, diameter and weight as well as root yield in both seasons. The highest values were obtained by delaying the harvesting up to 225 days from sowing. Concerning the quality traits, neither the harvesting date nor the varieties affected sucrose, purity (QZ), sodium, potassium, α-amino N and sugar recovery percentages in both seasons. However, the upper mid-harvesting date i.e. age of 195 days from sowing recorded the lower significant impurities and SLM percentages in the 1st season only.

The increasing human population risks food insecurity especially food of animal origin. Pig plays an important role in household income in all production. The main aim of this study was to analyze the pig farming profitability and constraints in smallholder households in Rwanda. A multistage sampling technique was employed for the success of the research. The study was carried out in five sectors of Musnze district. A purposive sampling technique was used to select Musanze district and five sectors. However, a random sampling method was used to have a sample size of 120 pig farmers’ respondents. The cost and returns associated with pig farming production were carried out to determine the profitability of pig production while a stochastic frontier production function was used to determine factors influencing pig farming in small householders using STATA. The findings indicated that men are the majority of the respondents in pig farming production in the study area. The findings of the regression analysis indicated that five factors namely education level, market availability, off-farm generation, feed availability, and access to veterinary services were positive, and statistically significant at P ≤ 0.01 level of probability and influenced pig farming in the study area. The findings also indicated that the Total Revenue (TR), Total Cost (TC), Gross Margin (GM), and Net Farm Income (NFI) were statistically significant at (p < 0.01). The research findings indicated that pig farming is a profitable business in the study area. The result of regression analysis also indicated that the three factors namely income generation, employment opportunities, and new job creation had positive and statistically significant impacts on pig farming in the study area at P ≤ 0.01 level of probability. The findings of this study revealed that the most common constraints for pig farming in smallholder households were the high cost of feeds, inadequate initial capital, feeds sacristy and quality, lack of conservation facilities, pests, and diseases outbreaks, high cost of piglets, lack of farming information, and poor housing. Despite the constraints indicated by different respondents in the study area. Pig farming is an economically profitable business in the study area and it is capable of creating new jobs, enhancing employment opportunities, generating income, and clearly improving the standard livelihood of farmers. Based on the findings of the study, it has been recommended to promote interventions that can help provide initial start-up capital for farmers or marketing groups to help kick-start their farming operations; and to train and equip pig farmers and veterinaries in new technologies and innovations. Promote the analysis of profitability, opportunities, and constraints along the pig value chain as well as to support and improve the underlying business progress or stunting well as to make a good decision.
人口的不断增长带来了粮食不安全的风险，尤其是动物源性食品。在所有生产活动中，养猪对家庭收入起着重要作用。本研究的主要目的是分析卢旺达小农户养猪的盈利能力和制约因素。为使研究取得成功，采用了多阶段抽样技术。研究在 Musnze 地区的五个区进行。在选择穆桑泽县和五个区时采用了目的性抽样技术。不过，随机抽样法的样本量为 120 个养猪户受访者。对养猪生产的相关成本和收益进行了分析，以确定养猪生产的盈利能力，同时使用 STATA 随机前沿生产函数确定影响小户养猪的因素。研究结果表明，在研究地区的养猪生产中，男性受访者占大多数。回归分析的结果表明，教育水平、市场可得性、非农创收、饲料可得性和兽医服务可得性这五个因素对研究地区的养猪业有正向影响，且在 P ≤ 0.01 的概率水平上具有统计学意义。研究结果还表明，总收入 (TR)、总成本 (TC)、毛利率 (GM) 和农场净收入 (NFI) 在 P < 0.01 的情况下具有统计学意义。研究结果表明，养猪业在研究地区是一项有利可图的行业。回归分析的结果还表明，在 P ≤ 0.01 的概率水平上，创收、就业机会和创造新的就业机会这三个因素对研究地区的养猪业具有积极的统计意义上的影响。研究结果表明，小农户养猪业最常见的制约因素是饲料成本高、初始资本不足、饲料储藏室和质量、缺乏保育设施、病虫害爆发、仔猪成本高、缺乏养殖信息以及住房条件差。尽管研究地区的不同受访者都指出了这些制约因素，但养猪业是一个经济上有利可图的行业。养猪业在研究地区是一个经济上有利可图的行业，它能够创造新的就业机会，增加就业机会，创造收入，明显改善农民的生活水平。根据研究结果，建议促进干预措施，帮助为农民或营销团体提供初始启动资金，以帮助他们启动养殖业务；并对养猪户和兽医进行新技术和创新方面的培训和装备。促进对养猪价值链上的盈利能力、机遇和制约因素进行分析，支持和改善基本的业务进展或发育不良情况，以便做出正确的决策。

Tef (Eragrostis Tef) is one of the most important cereal crops in Ethiopia and holds significant importance for food security, nutrition, and income generation for smallholder farmers. However, its production faces various challenges, including low yields, which is caused by limited access to improved varieties and lack of knowledge on best agronomic practices. The study was aimed at enhancing the adoption of new tef technologies by raising farmers' awareness towards better management practices in the study area. The newly released Boni variety along with the standard checks (Bora and Boset) was demonstrated during the 2022 main cropping season. Yield data was collected and analyzed using descriptive statistics. The farmers preference and feedback were evaluated using direct ranking and narration respectively. The finding showed that the highest grain yield (2.22 tha–1) was obtained from Bora variety in the Minjar Shenkora district of North Shewa zone, Amhara regional state. Conversely, the lowest average yield (1.84 tha–1) was recorded from Boni variety in the Bora district of East Shewa zone, Oromia regional state. The yield increment of Boni over Bora ranges from -4.2% to 1.0% across the districts. Furthermore, comparing Boni to the Boset variety, Boni consistently demonstrated higher yields, with yield advantages ranging from -1.1% in the Bora district to 7.2% in the Boset district. In contrast, the yield advantage of Boni over farmers' practices varies across districts, ranging from -14.4% in Bora district to 5.9% in Minjar Shenkora district. Similarly, Boni variety was selected first, followed by Bora and Boset varieties in Boset and Bora districts, while Bora variety was selected first followed by Boni and Boset variety in the Liben Chiquala and Minjar Shenkora districts. Therefore, it is recommended to promote the selected varieties in the specific target areas as well as other similar agro-ecological areas by involving all the concerned stakeholders at different levels.

Maize is the most extensively produced crop in both Africa and Ethiopia in terms of both land area and production. However, low soil fertility, non-agronomic methods, disease, pests, weeds, and insufficient water, negatively affect its yield. Although there are a lot of maize farming in the Jimma Zone, the yield is very low. The variability of rainfall is one of the causes of the low production, and it has to be supplemented through irrigation. This study was initiated with the objective of determining the effect of supplementary irrigation on the production and productivity of maize (Zea mays L.) under rain-fed agriculture. The field experiment was carried out for three consecutive years, from 2020 to 2022, on the maize (Zea mays L.) crop at the Jimma agricultural research center. The plots were laid out in a randomized complete block design (RCBD) consisting of eight treatments in three replications. The results of the analysis of variance showed that, the different levels of supplementary irrigation had a highly significant (P < 0.05) effect on ear height, but there was no significant difference on plant height. Grain yield and 100 seed weight were significantly (p<0.05) influenced by the application of different levels of supplementary irrigation. The pooled mean analysis indicated that the highest grain yield of 10623.1 kg ha-1 and 100 seed weight of 56.19 gm/plot were recorded from the application of full irrigation (100% ETc). However, the plot with rain fed has given the lowest grain yield (5216.5 kg ha-1) and the lowest 100-seed weight (41.97 gm /plot). In this study, there was a 49.1% yield increment between the fully supplied and the rain-fed maize. The result of partial budget analysis of maize showed that, the highest marginal rate of return and maximum net benefit of 16118 % and 255465 ETB were recorded from one SI at flowering stage and full Supplementary irrigation, respectively. The lowest net benefit (125984 ETB) was obtained at a rain fed treatment. Even though the marginal rate of return was lower, for a sustainable production of maize a full supply irrigation can be recommended.

Irrigation technologies that save water are necessary to ensure the economic and environmental sustainability of agriculture. Accurate irrigation planning is critical to improving irrigation efficiency. Therefore, this activity aimed to evaluate the responses of potato plants to the irrigation system (when and how much) and to determine the water productivity (WP) under optimal irrigation system. During the 2020 and 2021 irrigation season, a field trial of five irrigation treatments (20% ASMDL, 40% ASMDL, 60% ASMDL, 80% ASMDL and 100% ASMDL (FAO recommended ASMDL) irrigation) was conducted in Odo Shakiso district. The experiment was set up in a randomized complete block design (RCBD) with three repetitions. For the Irrigation Treatment at Allowable Soil Moisture Depletion (ASMDL), irrigation was scheduled when 35% of the total available water was depleted. Results showed that potato tuber yield, number of tubers per plant, and water productivity were significantly affected between treatments (P<0.05). Plant height, tuber weight and non-marketable tuber yield did not vary significantly between treatments. The highest marketable tuber yield (32.91 t ha-1) was achieved using irrigation water with 100% ASMDL. Reducing soil moisture loss from the recommended level (0.35) did not increase water productivity. However, no significant difference in water productivity was observed between irrigation water application at 60% of the ASMDL and irrigation water application at 100% of the ASMDL (FAO recommended depletion limit). Therefore, it can be concluded that the application of the FAO recommended ASMDL can provide the highest marketable tuber yield and water productivity of potatoes in the study area and in a similar agro ecology. Therefore, further investigation and verification work under different climatic conditions is recommended.

Accurate irrigation planning is critical to improving irrigation efficiency. Therefore, this activity aimed to evaluate the responses of potato plants to the irrigation system (when and how much) and to determine the water productivity (WP) under optimal irrigation system. During the 2020 and 2021 irrigation season, a field trial of five irrigation treatments (20% ASMDL, 40% ASMDL, 60% ASMDL, 80% ASMDL and 100% ASMDL (FAO recommended ASMDL) irrigation) was conducted in Odo Shakiso district. The experiment was set up in a randomized complete block design (RCBD) with three repetitions. For the Irrigation Treatment at Allowable Soil Moisture Depletion (ASMDL), irrigation was scheduled when 35% of the total available water was depleted. Results showed that potato tuber yield, number of tubers per plant, and water productivity were significantly affected between treatments (P<0.05).
