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.","PeriodicalId":281326,"journal":{"name":"Poljoprivredna tehnika","volume":"492 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123520332","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}

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.","PeriodicalId":281326,"journal":{"name":"Poljoprivredna tehnika","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125770671","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}

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.","PeriodicalId":281326,"journal":{"name":"Poljoprivredna tehnika","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126183509","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}

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.","PeriodicalId":281326,"journal":{"name":"Poljoprivredna tehnika","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114245505","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 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.","PeriodicalId":281326,"journal":{"name":"Poljoprivredna tehnika","volume":"209 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115563274","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}
