This research work is an attempt to apply experimental design to boost the yield of vegetables (Lablab purpureus) through the application of fertilizer levels and spacing. The field experiment consists of two spacing viz., 45x15 cm
(S1) and 60x15 cm (S2) and eight fertilizer levels viz., F1-25:50:25 kg NPK per ha (RdF), F2-33:50:25 kg NPK per ha, F3-25:67:25 kg NPK per ha, F4-25:50:33 kg NPK per ha, F5-33:67:25 kg NPK per ha, F6-25:67: 33 kg NPK per ha, F7-33:50:33 kg NPK per ha and F8-33:67:33 kg NPK per ha. This is laid out in RBD with factorial concept in three replication. Significantly higher pod yield (20.19 q/ha), seed yield (16.81 q/ha), were recorded in S1 compared to S2 spacing, Whereas, pods per plant (20.60), seeds per pod (19.29), seed yield per plant (16.54g), 100 seed weight
(28.43 g), germination (70.65%), and field emergency (66.92) were higher in S2 compared to S1 spacing. More pod yield per ha (22.24 g), seed yield per ha (18.50 q), and seed yield per plant (19.95 g), 100 seed weight (32.26 g), and germination percentage (73.35) and field emergency (83.97) were higher in F8 fertilizer level compared to F1 fertilizer level. The interaction effects of S1xF8 recorded significantly more pod yield (23.48 q/ha), seed yield
(20.00 q/ha) compared to S2xF1.




Experimental design is about theory, methods and application of techniques to remove subjectivity and systematic variation, to enhance the scope of inference, isolate experimental error and optimize precision of estimates and test in experimentation.

Design Analysis

...Remote controls are used frequently at home, in the office, and even in the classroom. This pervasiveness stresses the importance of having a good design in order for the user to be able to interact with the TV with minimal problems. The manufacturers take this into consideration when they built the TV by aiming to provide a remote control that supplements the TV they have designed. However, remote controls fail over time and must be replaced and manufacturers don’t tend to offer a replacement for a specific TV model. Therefore, the TV owner must find a universal remote that is useful, it supports the capabilities of their TV, and that has good usability. With this in mind, through the course of this paper I will be reviewing the design of what I believe to be a bad universal remote compared to a good universal remote by giving a personal example of each. I had to replace the remote of my 25 year old Sony TV and I decided to get the cheapest one they had at RadioShack, which turned out to a very bad universal remote overall. Getting the universal remote setup with my TV required me to press certain buttons in the correct sequence and then entering the right code for my TV model. The whole process was straight forward enough, but there were multiple codes for my model TV so I had to perform the setup steps multiple times before I got it to sync with my TV. Once setup, I noticed that the remote did not have buttons for certain features offered by my TV, input selection......

...have outputs that the people project will need to draw on. For example, the process of creating data models and data flow diagrams may raise questions of data ownership, which need to be fed to the people project to resolve, perhaps through a redefinition of rolesand responsibilities or the introduction of a new procedure. Likewise, if systems analysts have done a detailed assessment of costs and benefits, this will give the people project some idea of the messages they can use to sell the new IT system to users and managers. Analysts can also draw on the people project for valuable help in areas such as human–computer interface design, discussed in Chapter 15. The look and feel of the HCI can be one of the most significant factors in determining a user’s response to a system. The people project can help create the conditions in which HCI design can be done collaboratively, thus ensuring that both sides get what they need from this all-important aspect of the system. Very often, analysts and designers do more communicating about an IT Project than any other group. Analysts have extensive contact with the people who will ultimately use the system, as well as with the budget-holders who are actually paying for and steering the development project. They probably know more about the user community’s expectations and desires than line managers. They are often more up to date on decisions about the final size and shape of the system, when it will be implemented; even what......

Job Analysis and Job Design

...San Beda College GRADUATE SCHOOL OF BUSINESS 1 BUS 117-C1 HUMAN RESOURCE MANAGEMENT Job Analysis and Job Design Reported by: Josephine dela Cruz Garces Job Analysis and Job Design Clearly, the case above is a manifestation of poor human resource practice. There is an apparent lack of job analysis and job design that could have produced the document and the system that would minimize, if not totally eradicate, cases similar to that mentioned from occurring. Meaning and Nature of Job Analysis Job analysis, as a human resource practice, pertains to “the systematic process of determining the skills, duties, and knowledge required for performing jobs in an organization.” (Mondy, 2012). In similar manner, Dr. Roque (2005) defined job analysis as “the process of determining and reporting pertinent information relating to the nature of a specific job” (Roque and Edralin, 2005). As such, job analysis is an activity that sets in detail the tasks necessary in performing one‟s duties in an organization. It so to speak acts as the employees‟ „bible‟ that would set the standards and needed qualifications in successfully performing one‟s functions in the organization. In any organization, this function is the starting point of human resources management. Clearly, other HR functions such as, but not limited to, hiring, performance appraisal, training needs analysis, compensation management, cast dependence on it. This can be manifested in the following paradigm: “That In All......

Design and Analysis of a Chassis

...DESIGN AND ANALYSIS OF A CHASSIS FOR A 60 TON PAY LOAD Abstract: As the chassis frame forms the backbone of a heavy vehicle, its principal function is to safely carry the maximum load for all designed operating conditions. To achieve a satisfactory performance, the construction of a chassis is the result of careful design and rigorous testing. Various manufacturers have individual design concepts and different methods of achieving the desired performance standards for the complete chassis, not all chassis components are interchangeable between various makes and models of vehicles. So, there is no standard design for chassis frame. Even though start with the chassis frame design start with selection of the section for side rails and cross members. In this paper we have designed a chassis for storage cum resting fixture. Storage cum resting fixture is a structure of length 11000mm & width 2300mm, used to store cylindrical specimens of various sizes and weights in horizontal configuration. The storage cum resting fixture is used to carry the propellant stored in the cylindrical specimens. The trolley fixture should be designed for a maximum pay load of 60 tons. The Objective of my project is to design a chassis for a pay load of 60 Tons. The design process involves manual design calculations, 3d modeling using UNIGRAPHICS software and analysis to validate the design. Ansys package has been implemented to perform the structural analysis. ...

System Design & Management Analysis

...SYSTEM DESIGN & MANAGEMENT ANALYSIS System Design & Management Analysis Veronica Brown-Corbin University of Phoenix Contemporary Systems Management MGT/736 Brian E. Polding, Ph.D March 12, 2007 System Design & Management Analysis Management must recognize the system design and management of an organization are subject to internal and external influences. The internal influences include the management team and employee; and the external influences can include competitors and customers. There are contextual/cultural factors and stakeholders that have an influence on the management system that is designed and implemented. The contextual/cultural factors include key characteristics of the organization, internal and external relations, competitive landscape, strategic opportunities and challenges, and performance improvement. This is an opportunity for executive management to become acquainted with how these influences shape the organization’s context and maximize value for stakeholders. “Leadership’s job was to get the strategy right, design the correct structure, and then tie the strategy to structure through defined systems to deliver high-quality performance” (Nowicki & Summers, 2007, p.118). This is not an easy process and takes time and input from several sources. The leadership in the organization has to guide the organization so that the goals and objectives are met. The performance of the organization will benefit from a well carried out strategic......

Planning and Design Analysis

...Planning and Design Analysis of a Qualitative Research Study NUR/443 Evidence-Based Nursing Research and Practice Planning and Design Analysis of a Qualitative Research Introduction A qualitative research is a “systematic, subjective approach used to describe life experiences and give them meaning” (Burns & Grove, 2011). With this type of research, the data are collected through interviews, focus groups, observations, and review of documents. Thus, qualitative research uses words instead of numbers. This paper is going to analyze the planning and design of a qualitative research paper titled: Patient’s experience of pain and pain relief following hip replacement surgery, published in the Journal of Clinical Nursing on October, 2010. Research questions Although the research question or questions are not clearly labeled in the study, the research questions were as follows: 1) How do patients describe their experience with pain after hip replacement surgery?, 2) How do patients describe their pain relief following hip replacement surgery?, 3) How does pain affect patients after hip replacement surgery? Problem A research problem is “an area of concern in which there is a gap in the knowledge base needed for nursing practice” (Burns & Grove, 2011). In this research, it was identified that many patients undergo hip replacement every year and previous research has focused largely on the long-term effects of pain for these patients but not so much on their......

Job Analysis and Job Design

...Human Resource Management: Assignment 1 1 Job Analysis and Job Design Introduction Human Resource Management (HRM) systems consist of two major components: job analysis and job design. They have widely-differing contributions on building HRM systems attributed to the change of organizational strategy. This regards to job descriptions, specifications, and different approaches to redesigning the organizational HR systems. The implications of a boundary-less organization are examined that all context of the boundary organization is interdependent in communications, recruitment, selection, compensation and training (Fombrun et al. 1984). It also examines how environment, strategy, and organization are correlated to each other regarding to the conceptual framework for both job analysis and design of work. It initially becomes the most significant element to organizational strategy as to maximize organizational performance. This essay discuss how job analysis and design of work contribute in terms of building a more sophisticated human resource management (HRM) systems, regarding to both positive and negative outcomes from different approaches. It also illustrates the contributions of changeable job analysis in a regular basis as to fulfill the rapid-changing demand of working environment, in addition to a well-developed job redesign approach to support organizational strategy.
