JOURNAL OF AGRICULTURE, SCIENCE AND TECHNOLOGY 2023-05-08T00:00:00+00:00 JAGST Office Open Journal Systems <p>The Journal of Agriculture, Science, and Technology (JAGST) is a peer-refereed biannual publication first produced in 1997. It features research articles in Agriculture, Biotechnology, Forestry, Human and Veterinary Medicine, Engineering, Architecture, Information Technology, and Physical and Social Sciences. It also carries current scientific reports and, occasionally, reviews of publications with a scientific orientation. <br />The journal serves as an important tool in the mandate of the University’s Research, Production and Extinction (RPE) Division to facilitate dissemination of research findings. <br />The goal of the Journal is to:</p> <ul> <li>Provide a forum for the University staff and students, and researchers from the region and other parts of the world to participate in the discovery, transmission, <br />preservation and enhancement of knowledge in various disciplinary areas.</li> <li>Contribute towards the University’s goal of integrating teaching and research for effective application and preservation of knowledge and skills.</li> <li>Provide a platform for sound academic discourse among researchers.</li> </ul> <p>To view issues that were published in the past years i.e. before 2010 click this link :<a href="">Previous JAGST issues before 2010</a></p> An Object-oriented Programming Solution for Managing Inventory of Used Cars in Kenya Using Inheritance Relationships. 2023-05-05T12:34:58+00:00 Waweru Mwangi <p>The industry of buying and selling used cars in Kenya has continued to grow by leaps and bounds. There are many dealers who have opened shops in Nairobi, Mombasa, and many other towns locally. Therefore, having a software solution that can manage this data appropriately is important for the day-to-day running of these businesses. Inheritance is a key concept in object-oriented programming that uses the concepts of generalization and specialization. Inheritance allows a new class to extend an existing class. The new class inherits the members of the class it extends. This review paper explores the use of inheritance in developing software that used car dealers can find useful in managing their data.</p> <p>&nbsp;</p> 2023-05-08T00:00:00+00:00 Copyright (c) 2023 Waweru Mwangi Quality changes in papaya fruit under different storage temperatures and duration 2023-03-29T05:22:53+00:00 Christinah Matsuane Agnes Mumo Kavoo Beatrice Nyanchama Kiage Josephine Karanja Fredah Karambu Rimberia Wanzala <p>Kenya experiences high postharvest losses in the fruit and vegetable subsector which have been estimated to 50%. These losses are mainly due to poor postharvest handling practices, lack of storage facilities and/or poor storage conditions. Papaya (<em>Carica papaya</em> L.) is a highly perishable climacteric fruit with a short shelf life and requires proper storage and handling practices due to its delicate skin texture, high moisture content and its high respiratory rates. In this study, F hybrid and Mountain variety papayas were collected at Meru county in May 2022 and stored at three different temperatures (6, 16 and 24 ˚C) for a duration 0, 4, 8 and 12 days to evaluate their effects on the nutrient and biochemical retention. Data collected was subjected to a two-way ANOVA (separately) in a completely randomised block design, using GenStat statistical software package (14<sup>th</sup> edition). Storage temperatures and durations significantly (p&lt;0.05) decreased papaya firmness, peel and flesh hues; vitamin C, potassium, iron, moisture content from 6 to 24 ˚C while there was an increase in carbohydrates and total soluble solids (TSS). Mountain fruits had more moisture, carbohydrates, iron and TSS while F fruits had appealing peel and flesh colours and retained more potassium. Successful nutrient retention of the papaya fruits was attained at 16 ˚C&nbsp; and 8 days. F hybrid fruits were comparable to the local papaya variety, Mountain, on the various tested parameters which could make it suitable for consumer utilisation and market exploitation in Kenya.</p> 2023-05-08T00:00:00+00:00 Copyright (c) 2023 Christinah Matsuane, Agnes Mumo Kavoo, Beatrice Nyanchama Kiage, Josephine Karanja, Fredah Karambu Rimberia Wanzala
