This study investigates the quality composition of Aba knife fish (Gymnarchus Niloticus) predominant in South-eastern Nigeria. The fish sample require proper processing techniques to preserve their organoleptic qualities for a substantial period. The objective of the study was to investigate the influence of oven-drying process on the proximate and organoleptic qualities of Gymnaruchus Niloticus. The studied fresh fish fillets were rinsed in clean water, brined and spread in trays before taken for oven drying. An oven drier (FALC STF-F-52) was used for the oven-drying process. Analyses of proximate compositions (moisture content, crude lipid, crude protein, ash content and crude fiber) were carried out on the fresh and oven dried fish samples. The study showed that oven drying decreases the moisture content to a safe level of 38.13 ± 0.01% dry basis(d.b), and increase the crude protein content (18.23±0.01), fat content (4.34±0.01), ash content (3.40±0.01), carbohydrate content (35.96±0.01) of the investigated fish samples. There were no crude fibre contents (0.00) in the fresh fish samples. Therefore, the oven drying process had no noticeable effect on the fibre content. The oven dried fish samples were rated high in terms of taste, aroma, colour, texture and general acceptability by the panel of assessors. The significance of the obtained results as well as recommendations for further studies were offered.

This study examined the socio-economic factors underlining arable crop famers' use of mobile phones for agricultural-related purposes in Iwo Agricultural Development Program (ADP) Zone of Osun State. Multistage sampling procedure was used to select 150 arable crop farmers from whom primary data were collected with structured interview schedule. Data obtained was analyzed using descriptive statistics and ordinary least square regression analysis. Findings from this study revealed that most frequently used applications include voice call (99.3%), calendar (96.7%), calculator (96%) and torch light (95.3%). Most of the farmers strongly consented that mobile phones facilitated timely access to needed services (𝑋̅ = 4.74), eased production decision making (𝑋̅ = 4.54), enhanced increased income and profit (𝑋̅ = 4.50) and accessing personalized information about new farming techniques (𝑋̅ = 4.44). Major constraints identified for limiting the usage of phones for agricultural purposes were poor internet access (𝑋̅ = 3.73), inadequate electricity to charge t he mobile phone (𝑋̅ = 3.55), poor network access (𝑋̅ = 3.54) and high charges on services (𝑋̅ = 3.41). Gender (b= 4.337; P˂ .01), level of education (b= 16.358; P˂ .01), years of farming (b= 0.513; P˂.05), information sources (b= 0.645; P˂.01) all jointly had positive influence on farmers' use of mobile phones for agricultural information. It was recommended that higher capacity of female and arable crop farmers with lower level of education should be energized to utilize their mobile phones for enhancing their production activities.

The article reviewed the application of compost to the plants in providing essential macro-nutrients such as Nitrogen (N), Potassium (K) and Phosphorus (P), and micro-nutrients, ie. Iron (Fe), magnesium (Mg), copper (Cu), Zinc (Zn), and Boron (B) and enhances microbial activity. Nutrients are released slowly due to strong association of compost with organic matter. This property makes compost an excellent alternative to inorganic fertilizers as leaching and volatilization losses are reduced. Over-reliance on the use of chemical fertilizers has been associated with declines in soil physical and chemical properties and crop yield, and significant land problems, such as soil degradation due to over exploitation of land and soil pollution caused by high application rates of fertilizers and pesticide application. The reduction in the use of chemical fertilizers and supplementing the same through organic manure such as urban compost, otherwise known as municipal solid waste (MSW), Farm yard manure (FYM), poultry manure (PM), etc., become necessary to sustain productivity, profitability and to maintain soil health. Application of FYM is practiced for many years but it has become scarce due to scanty population of livestock, therefore urban compost is one of the alternative sources of organic manure.

Tillage is the basic operation in agriculture and its energy requirements represent a considerable portion of the energy utilized in crop production. The trials were achieved using five tractor speeds (3.6, 5.4, 7.2, 9.0 and 10.8 km/hr) and five tillage depths (10, 15, 20, 25 and 30 cm) to determine implement speed at different tillage depths for 3-bottom disc plough, spring tine cultivator and offset disc harrow on loamy soil. The design of the experiment used were two factors, five levels factorial of Central Composite Rotatable Design of Response Surface Method. Selected models were analyzed using ANOVA at ao. 05 and also validated. The high values of the coefficient of determination for all the selected models and the reasonable agreement between the predicted and actual values of draft and power requirement for all the tested implements show that the generated model equations can be used for predictive purposes for draft and power requirement.

The objective of this study was to determine the input-output energy of olive cultivation in a semiarid region of Çanakkale, Republic of Turkey. Data were collected from olive farmers by a questionnaire for traditional-flat/sloping and intensive-flat systems in last growing season. The results revealed that net energy gain was higher in intensive system than in traditional flat and sloping ones. Similarly, energy ratio was higher in intensive by 1.46 MJ ha-1 than in sloping and flat of traditional by 1.42 and 1.38 MJ ha-1 , respectively. The highest energy productivity was recorded in the intensive (0.93 MJ ha-1), but the lowest was in the traditional-sloping (0.75 MJ ha-1), and then in the traditional-flat (0.92 MJ ha-1). Indeed, the intensive system produced higher olive yields which allow using a higher level of fertilizer, water and mechanization, but also the energy analysis revealed that its efficiency in the energy was higher than two traditional systems. The results suggested that intensive system could be a better cultivation system in flat areas for the region farmers in an increasingly competitive without worsening environmental sustainability.

: The principal aim of this study was to examine the nutrient release pattern from two types of composts and long-term implications on soil fertility status. An incubation experiment was carried out in the laboratory to determine the nutrient release patterns from compost and vermicompost mixed with soil at different application rates of SC30, SC70, SC120 and SV30, SV70 SV120 respectively for 21 days. Initial pre-incubation analysis of the compost material used for the experiment showed that both the compost and vermicompost had high nutrient content. The results further revealed that the different rates of compost and vermicompost application to soil had significant influence on the slow, gradual release process, indicating the long-term effect the organic fertilizers could exert on soil fertility status

According to UN Food and Agriculture Organization [1], the population of the world will increase by 2 billion by 2050. However, only 4% additional land will come under cultivation by then. It could be inferred that, with the global population expected to reach 9.1 billion in 2050, 70 percent more food needs to be produced, otherwise about 370 million people would be in hunger in 2050. In this light, the use of latest technological solutions to make farming more efficient remains one of the greatest imperatives. While Artificial Intelligence (AI) sees a lot of direct application across sectors, it can also bring a paradigm shift in how we see farming today. AI-powered solutions will not only enable farmers to do more with less, it will also improve quality and ensure faster go-to-market for crops. This paper presents a review of the applications of AI in tractor field operations. The paper discusses elaborately, the use of robotics as a form of artificial intelligence which is very useful in tractor field operations such as tillage, weeding, seeding, herbicide spraying, and harvesting. A typical focus is laid on the strength and limitations of the applications and the way in utilizing expert systems for higher productivity.

Hydrogen Fuel Cell Vehicles (FCVs) are similar to EVs, in the aspect that they use an electric motor instead of an internal combustion engine to power the wheels. The main difference is that EVs run on batteries that must be plugged in to recharge, while FCVs generate their electricity onboard. This manuscript presents overview of the hydrogen vehicle certification legislation. Inspection and testing of motor vehicle technology today represent a set of a whole series of procedures that are applied in different stages of the vehicle development, production and operation of vehicles, and whose task is to provide objective information about the quality of the vehicle and its assemblies and parts, as well as about the conditions in which the vehicles operate, about workloads, environment, etc. Although there are adopted technical regulative for hydrogen powered EVs, the appropriate standards and legislation are still evolving.

Emphasizing the importance of establishing the link between poorly archived 4 forms of documentation in relation to the introduced form of archiving in agricultural enterprises in Serbia is one of the important issues in the movement of documentation in these companies. The authors analyzed 4 forms of documentation, namely: contracts, solutions, opinions and instructions on archiving in relation to the two forms of archiving documentation in companies (a new way of archiving-electronic and classic way of archiving documentation). The focus of the research of the authors of this study was the question of discovering a possible connection between poor record keeping, i.e. poor archiving of documentation in an agricultural company and the established form of archiving in the mentioned companies. The authors conducted research in 144 agricultural enterprises, and the results they obtained indicate that much fewer errors occurred in the case of electronic archiving of documentation (about 100% fewer errors) compared to classical archiving in agricultural enterprises.

Irrigation has become very critical in acquiring an all year round crop production. The aim of the research work was to assess the irrigation water quality and selected soil parameters at the Mankessim irrigation scheme, which is used to irrigate all types of crops within Mankessim and its environs. The data of the study was collected from two sources, from water and soil samples. Water samples were collected from three different surface water sources within the scheme for both the dry and wet seasons. Nine (9) different samples were collected for each season, three (3) samples for each surface water source. Also, six (6) different soil samples were collected for each season. Soil samples were collected from an irrigated and non-irrigated farm lands. The results of the study indicated that water sources, that is from surface sources did not differ significantly from each other comparing the dry and wet seasons and that their chemical values were within the limits acceptable for irrigation and crop production. The concentrations (Na, Ca, Mg, EC and TDS) were fairly within the permissive limits for crop water use.
