Purpose: Promoting small-scale farmers’ market participation is perceived to be a motivation of transforming peasantry subsistence farming to commercialization for improved rural livelihoods especially in developing countries like Eswatini. Despite efforts by the government and other stakeholders the transformation process is too slow or stagnant mostly on non-traditional export food commodities including common beans in Eswatini. The drivers of small-scale common bean farmers ‘market participation and level of market participation in Eswatini are not known, hence this study.Objectives: The main objective of the present study is to find out the determinants of market participation among the smallholder common beans farmers in Eswatini.Research Methods: This study used secondary data accessed from Eswatini Agricultural Development Enterprise (ESWADE) under the Smallholder Market Lead Project was used. The data was cleaned and a total of 164 common bean farmers were considered for this study. The data was analysed using descriptive statistics and Heckman two-stage selection model.Findings: The results generated indicate that most respondents were females (63%). The results further show that there is a significant difference of 1.396 in the number of family size helping in farming between participant and non-participants. About 84.8% of the farmers depend on rain to water their beans. Gender, knowing size of land, method of watering and household farm labour size were found to be the determinants of common bean farmer’s choice and intensity of participation in the market.Recommendation: It is recommended that farmers should consider irrigating their crops, participate fully in farming activities and know their size of land because these factors has been proven to increase the intensity of market participation of bean farmers and the government should take initiative to provide more extension officers to conduct effective training and incentives that will encourage the middle age group to participate in sugar bean farming.Originality/ Value: This paper highlights the determinants of market participation among the smallholder common beans farmers in Eswatini as well as establishes the socio-economic characteristics of the small scale common bean farmers.
目的:促进小规模农户的市场参与被认为是将农民的自给农作转变为商业化以改善农村生计的动力,尤其是在像埃斯瓦提尼这样的发展中国家。尽管政府和其他利益相关方做出了努力,但转型进程过于缓慢或停滞不前,主要是在非传统出口粮食商品方面,包括埃斯瓦提尼的普通豆类。目前还不了解小型普通豆农参与市场的驱动因素和参与市场的程度,因此才有了本研究:本研究的主要目的是找出埃斯瓦提尼普通豆类小农参与市场的决定因素:本研究使用了小农市场领导项目下从埃斯瓦提尼农业发展企业(ESWADE)获得的二手数据。数据经过清理,共有 164 位普通豆农被纳入研究范围。采用描述性统计和赫克曼两阶段选择模型对数据进行了分析:研究结果表明,大多数受访者为女性(63%)。结果还显示,参与研究的农民和未参与研究的农民在帮助耕作的家庭人口数量上存在 1.396 的显著差异。约 84.8%的农民依靠雨水浇灌豆子。性别、了解的土地面积、浇灌方法和家庭劳动力数量是普通豆农选择和参与市场强度的决定因素:建议:建议农民考虑灌溉作物,充分参与农业活动,了解自己的土地面积,因为这些因素已被证明能提高豆农的市场参与强度,政府应主动提供更多的推广人员,开展有效的培训和激励措施,鼓励中年群体参与糖豆种植:本文强调了埃斯瓦提尼普通豆类小农户参与市场的决定因素,并确定了普通豆类小农户的社会经济特征。

This study examines the impact of rainfall on oil palm growth and productivity in the Berau region of East Borneo, Indonesia. The research utilized qualitative and quantitative field studies, employing correlation and regression analysis. The study focused on the oil palm plantation area as its subject. Data was collected from a plantation in the Berau region of East Borneo. The plantation has homogeneous plant age (same planting year, 2009) and homogeneous progeny (Scofindo variety) and is included in the company's core plantation. The observation parameters included rainfall, rainy days, fresh fruit bunches, and plant productivity. It was found that rainfall and rainy days have an impact on oil palm productivity. The regression results indicate a positive correlation between rainfall and oil palm productivity, with a correlation coefficient of 0.025109171. However, rainy days have a negative effect on oil palm productivity, with a correlation coefficient of -0.036778304, despite being positively correlated with rainfall. The correlation coefficient of 0.768386269 indicates a direct impact on reducing oil palm productivity. Rainfall indirectly affects oil palm productivity by influencing temperature, humidity, intensity, and length of daily irradiation. These factors directly affect the productivity of oil palm plants.
本研究探讨了降雨对印度尼西亚东婆罗洲 Berau 地区油棕榈树生长和生产力的影响。研究采用了定性和定量实地研究,并运用了相关和回归分析。研究以油棕种植区为对象。数据收集自东婆罗洲 Berau 地区的一个种植园。该种植园具有相同的株龄(同一种植年份,2009 年)和相同的后代(Scofindo 品种),并被纳入公司的核心种植园。观测参数包括降雨量、雨日、鲜果串和植物生产力。研究发现,降雨量和雨日对油棕生产率有影响。回归结果表明,降雨量与油棕生产率呈正相关,相关系数为 0.025109171。然而,尽管降雨量与降雨日呈正相关,但降雨日对油棕生产率却有负面影响,相关系数为-0.036778304。0.768386269 的相关系数表明,降雨对降低油棕生产率有直接影响。降雨量通过影响温度、湿度、强度和日辐照长度间接影响油棕生产率。这些因素直接影响油棕植物的生产力。

High cost of irrigation pumping by use of fossil fuel has negatively impacted irrigation efficiency on the Middle Ogun Irrigation scheme. Efficient irrigation pumping would improve agricultural productivity and food production on the irrigation scheme.  Many attempts have been made by stakeholders to seek alternative energy sources for powering irrigation pumping. This study aimed at the design and retrofitting of the irrigation water pumping system on the Middle Ogun Irrigation scheme using hydrokinetic technology. Hydrological modelling of the catchment was carried out using MapWindow Soil and Water Assessment Tool to determine the annual gross and recoverable hydrokinetic potential of the water resource from the river. A Savonius hydrokinetic turbine system was developed and tested on the river.  The mean voltage output at selected streamflow depths were determined to derive a power curve. Results showed that retrofitting the irrigation pumping system with an array of twenty units (20) of selected submersible irrigation pumps powered by twenty-two (22) units of an array of Savonius hydrokinetic turbines would satisfactorily deliver irrigation water into night storage and irrigate the pilot field of 100 ha of farmland on plot 2 and 5 on the scheme.
使用化石燃料进行灌溉抽水的高成本对中奥贡河灌溉计划的灌溉效率产生了负面影响。高效的灌溉抽水将提高灌溉计划的农业生产力和粮食产量。 利益相关者已多次尝试寻找替代能源,为灌溉抽水提供动力。本研究旨在利用水动力技术对中奥贡灌溉计划的灌溉抽水系统进行设计和改造。利用 MapWindow 水土评估工具对集水区进行了水文建模,以确定河流水资源的年总动能和可回收动能。开发了萨沃尼尔斯水动力涡轮机系统,并在河上进行了测试。 确定了选定水流深度下的平均电压输出,从而得出了功率曲线。结果表明,使用由二十二(22)台萨沃尼尔斯水动力涡轮机驱动的二十(20)台选定的潜水灌溉泵组成的阵列来改造灌溉抽水系统,可以将灌溉水输送到夜间储水库,并灌溉该计划中 2 号和 5 号地块的 100 公顷试验田。

A field experiment was conducted at the north western coast of Egypt under rainfed conditions to study the effects of seed rates (70, 95 and 120 kg ha-1) and nitrogen fertilizer treatments (0, 35, 70 and 105 kg N ha-1) of Ensiabeen-40% N as slow-release fertilizer compared with 105 kg N ha-1 as Ammonium nitrate (33.5%N) on productivity of barley cultivar Giza134. This investigation was conducted during 2019/2020 and 2020/2021 winter growing seasons. The treatments were laid out in a split plot design, with three replications. Plant height, spike length, number of grins spike-1, number of spikes per m2, 1000 grain weight, biological and grain yield were recorded. In addition, total income and net return (LE)/hactare were calculated. The results indicated that mean squares due to seasons, seed rates, nitrogen levels and their interactions were significant  for most studied traits. Mean performance of the studied traits as affected by seasons, seed rates and nitrogen levels showed that, the most desirable values were obtained by SR1 for spike length (6.13cm), number of grains spike-1 (48.78 grain) and 1000 grain weight (42.15g), from SR2 for Biological yield (6.02 ton ha-1) and grain yield (1.85 ton ha-1) and from SR3 for plant height (78.28cm) and number of spikes m-2 (180.11 spike). For nitrogen level effects, N4 recorded the most favorable values for all studied traits; plant height (81.48cm), spike length (6.33cm), number of grains spike-1 (49.99 grain), number of spikes m-2 (187.60 spike), Biological yield (6.88 ton ha-1), grain yield (2.12 ton ha-1) and 1000 grain weight (42.89g). Grain yield exhibited highly significant and positive correlation with each of plant height (r= 0.833**), spike length(r=0.621**), number of grains spike-1 (r=0.768**), number of spikes m-2(r=0.880**) and weight of 1000 grains (r= 0.661**). The most contributing variable in the total variation of grain yield were number of spikes m-2, number of grains spike-1 and spike length. These variables contributed by 92.9% in the grain yield variation. The results also indicated that, the highest values in the total income were 19149 and 24990 pound.hec-1 respectively, and net return were 9492 and 15498 pound.hec-1 obtained from the interaction between seed rate of 5kg ha-1 (SR2) and 105 unit of slow release fertilizer (N4) during the two growing seasons. It could recommend this treatment to maximize the total income for the farmers in such location.
在埃及西北部沿海地区的雨水灌溉条件下进行了一项田间试验,研究播种率(70、95 和 120 千克/公顷-1)和氮肥处理(0、35、70 和 105 千克/公顷-1)对大麦栽培品种 Giza134 产量的影响。这项调查是在 2019/2020 年和 2020/2021 年冬季生长季节进行的。处理采用分小区设计,三次重复。记录了株高、穗长、穗粒数-1、每平方米穗粒数、千粒重、生物产量和谷物产量。此外,还计算了总收入和净收益(LE)/公顷。结果表明,季节、种子率、氮素水平及其交互作用对大多数研究性状的平均方差具有显著影响。所研究性状受季节、种子率和氮素水平影响的平均值表明,SR1 的穗长(6.13 厘米)、穗粒数-1(48.78 粒)和千粒重(42.15 克)最理想,SR2 的生物产量(6.02 吨/公顷-1)和谷物产量(1.85 吨/公顷-1)最理想,SR3 的株高(78.28 厘米)和穗粒数 m-2(180.11 穗)最理想。在氮水平影响方面,N4 对所有研究性状的影响值最大:株高(81.48 厘米)、穗长(6.33 厘米)、穗粒数-1(49.99 粒)、穗粒数 m-2(187.60 穗)、生物产量(6.88 吨/公顷-1)、谷物产量(2.12 吨/公顷-1)和千粒重(42.89 克)。谷物产量与株高(r=0.833**)、穗长(r=0.621**)、穗粒数-1(r=0.768**)、穗粒数 m-2(r=0.880**)和千粒重(r=0.661**)均呈高度显著的正相关。对谷物产量总变异贡献最大的变量是穗粒数 m-2、穗粒数-1 和穗长。这些变量对谷物产量变化的贡献率为 92.9%。结果还表明,在两个生长季节中,5 千克公顷/公顷的播种量(SR2)与 105 单位的缓释肥(N4)交互作用的总收入最高,分别为 19149 和 24990 磅.hec-1,净收益最高,分别为 9492 和 15498 磅.hec-1。建议采用这种处理方法,以最大限度地提高该地区农民的总收入。

The dairy industry must adhere to stringent international standards due to the growing demand for healthy, high-quality, and affordable dairy products worldwide. To ensure the quality of raw milk, key markers such as Bulk Milk Somatic Cell Count (BMSCC) and Total Bacterial Count (BMTBC) have become standard benchmarks. However, mastitis, the most common disease affecting dairy cows, poses a significant risk to both animal welfare and the long-term sustainability of the dairy sector. Mastitis leads to reduced milk production, increased treatment costs, milk withholding during treatment, higher labor requirements, and premature culling of affected cows. In India alone, mastitis costs the dairy industry 2.37 billion rupees annually, with subclinical mastitis accounting for approximately 70% of this loss. While contagious infections have been effectively controlled, environmental mastitis pathogens such as Streptococcus uberis, Escherichia coli, and Klebsiella spp now pose the primary concern for mastitis control. The management of cow bedding materials is crucial as they serve as a significant source of exposure to these environmental infections. This review study provides a detailed discussion of environmental mastitis pathogen control, emphasizing the critical role of bedding materials in reducing the risk of exposure to these pathogens.
由于全球对健康、优质、廉价乳制品的需求不断增长,乳制品行业必须遵守严格的国际标准。为确保原奶质量,大量牛奶体细胞计数(BMSCC)和细菌总数(BMTBC)等关键指标已成为标准基准。然而,乳腺炎是奶牛最常见的疾病,对动物福利和乳制品行业的长期可持续发展都构成了重大风险。乳腺炎会导致产奶量下降、治疗成本增加、治疗期间停奶、劳动力需求增加以及过早淘汰患病奶牛。仅在印度,乳腺炎每年就给乳制品行业造成 23.7 亿卢比的损失,其中亚临床乳腺炎约占 70%。虽然传染性感染已得到有效控制,但环境性乳腺炎病原体,如尤伯杯链球菌、大肠埃希氏菌和克雷伯氏菌,目前已成为乳腺炎控制的首要问题。奶牛垫料是接触这些环境感染的重要来源,因此奶牛垫料的管理至关重要。本综述研究详细讨论了环境乳腺炎病原体控制问题,强调了垫料在降低接触这些病原体风险方面的关键作用。

由于气候变化、人口数量增加以及微生物(生物)和矿物质(非生物)胁迫等问题,小麦这种具有全球重要性的重要主粮作物面临着巨大的压力。杂交小麦是由差异很大的亲本杂交产生的,可以利用杂交来培育优良特性。然而,杂交小麦一直受到自花授粉、异交率低、生产成本高昂和消费者接受度低等问题的困扰。本研究探讨了杂交小麦的生产方式,如化学杂交剂、细胞质雄性不育和基因组选择。这方面涉及杂交小麦生产的困难和复杂性,如杂交不亲和、遗传不稳定、杂交家族多样化以及对杂交种活力进行基因组预测的要求。本文讨论了杂交小麦在印度的应用滞后问题,并特别关注与印度有关的特殊问题。 然而,仍有一些与杂交组合和不育系有关的问题是印度特有的。尽管如此,包括 ICAR 杂交网络或转基因方法在内的重大努力还是给未来带来了希望。最后,应该指出的是,尽管杂交小麦似乎很有希望获得高产和良好的谷物品质,但必须首先解决生物遗传方面的限制。如果杂交小麦有望在全球人口增长导致水资源日益减少的情况下提高粮食安全和改善营养状况,那么解决这些障碍是至关重要的。

This inquire about investigates the ways that these desires are playing out within the oil palm plantation in East Kalimantan. Oil palm plantation are East Kalimantan's breakthrough to extend community economic development whereas diminishing the region’s reliance on natural resources.  This investigate employments a qualitative descriptive analysis method from primary data gotten through literature studies and focus group discussions. We discover that oil palm plantation postures genuine  deforestation challenges to the concept of green development, as 44% of arrive apportioned for plantations is still forested. At the same time, there may be openings to dodge  deforestation and seek after more feasible oil palm improvment pathways, as 87% of concessions have however to be planted. The improvement of oil palm plantations is supported by few government regulations, in spite of the fact that their usage within the districts makes different impediments.
本研究调查了这些愿望在东加里曼丹油棕种植园中的实现方式。油棕种植园是东加里曼丹扩大社区经济发展的突破口,同时减少了该地区对自然资源的依赖。 本研究采用定性描述分析方法,从文献研究和焦点小组讨论中获得的原始数据中进行分析。我们发现,油棕种植对绿色发展理念提出了真正的森林砍伐挑战,因为 44% 的种植面积仍然是森林。与此同时,也有可能避免森林砍伐,寻求更可行的油棕榈改良途径,因为 87% 的特许权尚未种植。油棕种植园的改良几乎没有得到政府法规的支持,尽管它们在地区内的使用造成了不同程度的阻碍。

Termites are social insects and the mounds they develop are considered to be a waste. They fed on agricultural products and wooden structures and hence, they are considered to be destructive. The resultant mound soil is an agricultural soil which is rich in nutrients, but its usefulness in agriculture and construction industry had not been explored. Thus, the study evaluated the Growth and yields performance of maize raised on termite mound and surrounding soils in Owo, Ondo State, Nigeria. Maize was cultivated on the termite and surrounding soils as well as on their 50-50% mixture by weight and the data of the yields of maize was subjected to statistical analysis using T test at 95% confidence level. The yields of maize cobs per stands for termite mound soil in plots 1, 4, 7 were 1,2,1; for the surrounding soil in plots 3,6,9 are 1,1,1 and for the mixture of the surrounding; and the termite mound soil were 3,2,2. The yields of maize cultivated on plots 1, 4, 7 (TMS); 2, 5, 8 (TMS+SRS); 3, 6, 9 (SRS) using t-distribution table were O.75
白蚁是社会性昆虫,它们形成的土堆被认为是一种废物。它们以农产品和木质结构为食,因此被认为具有破坏性。由此产生的土堆土壤是一种富含养分的农用土壤,但其在农业和建筑业中的用途尚未得到探索。因此,这项研究评估了尼日利亚翁多州奥沃市白蚁丘和周围土壤上种植的玉米的生长和产量表现。研究人员在白蚁堆和周围土壤以及两者重量各占 50-50% 的混合物上种植了玉米,并对玉米产量数据进行了统计分析,采用 95% 置信度的 T 检验。1 号、4 号和 7 号地的白蚁丘土壤的玉米棒单株产量分别为 1、2、1;3 号、6 号和 9 号地的周围土壤的玉米棒单株产量分别为 1、1、1;周围土壤和白蚁丘土壤的混合物的玉米棒单株产量分别为 3、2、2。采用 t 分布表法,1、4、7(TMS);2、5、8(TMS+SRS);3、6、9(SRS)地块的玉米产量分别为 O.75

The study investigates the energy use pattern and economic analysis of fluted pumpkin production in tillage methods (traditional, reduced-conventional and conventional). Human power, machinery, diesel fuel, fertilizers, seed and pesticides energy inputs were used during the cultivation of fluted pumpkin. Input and output energy analysis method was used to estimate the input and output energy in each of the tillage methods during the production of fluted pumpkin. The energy indices of fluted pumpkin production determined were; energy efficiency, energy productivity, specific energy, net energy and energy efficiency index. The economic analysis of fluted pumpkin production in terms of total cost of production, gross monetary return, net monetary return and cost benefit ratio for the three tillage methods used were determined. The total energy required per hectare in traditional, reduced-conventional and conventional tillage methods were 6899.90, 9206.16 and 10176.84 MJ/ha, while the output energy were found to be 8912.48, 12297.8 and 12297.8 MJ/ha, respectively. The energy efficiency, energy productivity and net energy gain of 3.97, 1.50 and 1.20; 0.76, 0.86 and 0.71 MJ/kg; 1.32, 1.20 and 1.40 MJ/ha, respectively were estimated while energy efficiency index were found to be 27, 47 and 20% for traditional, reduced-conventional and conventional tillage methods, respectively. The highest net monetary return and cost benefit ratio of ₦382,000.00k and 3.05 were estimated for reduced-conventional, ₦351, 600.00 k and 2.31 for conventional tillage, while the least values of ₦220, 000.00 k and 2.11 were recorded for traditional tillage method. The result revealed that reduced-conventional tillage was better than both traditional and conventional tillage methods in terms of energy productivity, net energy gain and energy efficiency index. Economically, production of fluted pumpkin under reduced-conventional tillage shows the highest net monetary return and cost benefit ratio compared to the other two tillage methods considered.
本研究调查了凹槽南瓜生产在耕作方法(传统、减量-传统和传统)方面的能源使用模式和经济分析。凹槽南瓜种植过程中使用了人力、机械、柴油、化肥、种子和农药等能源投入。采用输入和输出能量分析方法估算了凹槽南瓜生产过程中每种耕作方法的输入和输出能量。确定的凹槽南瓜生产能源指数包括:能源效率、能源生产率、比能量、净能量和能源效率指数。确定了凹槽南瓜生产的经济分析,包括三种耕作方法的总生产成本、总货币收益、净货币收益和成本效益比。传统耕作法、减量传统耕作法和常规耕作法每公顷所需的总能量分别为 6899.90、9206.16 和 10176.84 兆焦耳/公顷,而产出能量分别为 8912.48、12297.8 和 12297.8 兆焦耳/公顷。传统耕作法、减少传统耕作法和常规耕作法的能源效率、能源生产率和净能源收益分别为 3.97、1.50 和 1.20;0.76、0.86 和 0.71 兆焦/千克;1.32、1.20 和 1.40 兆焦/公顷,能源效率指数分别为 27、47 和 20%。据估计,减少传统耕作法的净货币收益和成本效益比最高,分别为 ₦382,000.00k 和 3.05,传统耕作法为 ₦351,600.00 k 和 2.31,而传统耕作法的净货币收益和成本效益比最低,分别为 ₦220,000.00 k 和 2.11。结果表明,在能源生产率、净增能和能效指数方面,减少传统耕作法优于传统耕作法和常规耕作法。从经济角度看,与其他两种耕作方法相比,采用减量化常规耕作法生产凹槽南瓜的净货币收益和成本效益比最高。

A field experiment was conducted to investigate the effect of different levels of NPK on the performance of Thespesia populnea. A total of 17 treatments consisted of four levels of Nitrogen (50, 75, 100 and 125 g N plant-1), two levels each of Phosphorus (50 and 75 g P plant-1), and Potassium (25 and 50 g K plant-1) were tried in RBD replicated three times, to standardize the fertilizer schedule for the tree crop taken for investigation. The experimental soil was red sandy loam, non-calcareous, neutral in reaction, low in available nitrogen, phosphorus and medium in available potassium with low organic carbon content. Ecophysiological parameters viz., photosynthestic rate (A), transpiration rate (E), stomatal conductance (gs) and Intercellular CO2 concentration (CINT). Growth attributes were influenced by N, P and K at different levels. Among the various treatments application of 100 : 75 : 50 g NPK plant-1 (T12) significantly  influenced the growth attributes followed by 100 : 75 : 25 g NPK plant-1 (T11).
