Download or read book Evaluation of performance of selected tillage tines regarding quality of work written by Amer Khalid Ahmed Al-Neama and published by Springer. This book was released on 2018-06-22 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines and evaluates the performance of four standard chisel plough tines: heavy duty, double heart, double heart with wings and duck foot, which were connected with a rigid shank. Experiments were conducted in a soil bin filled with sandy loamy soil, and the experimental factors included varying operation conditions (speed and depth) and their dependency upon a draft force and their components (horizontal and vertical force), specific force (force per unit area), specific power (power per unit area), soil loosening percentage (above and below the original soil surface) and soil profile parameters (e.g. furrow height, furrow width, ridge height, area of ridge and furrow etc.). The evaluation involved developing regression equations based on Glancey and Upadhyaya’s model by adding new terms related to the tine geometric parameters or by adding a dummy term variable. These two techniques made up the general study parameters and had the same trend effect on operation conditions to compare between tines. Lab results such as force components and the width of furrow were verified in a field test. Furthermore, a model to predict the draft force by using principles of soil mechanics and soil profile evaluation was designed.

This book was released on 2012-04 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: High wear rate of tillage tools and the increasing difficulty of importing replacements have constituted major constraints to tillage practices on Nigerian soils. Also, farmers and equipment operators constantly complain about the high wear rate of ground tools especially in dry land agricultural areas. To this end, most existing cultivators are underused or totally abandoned in some cases because of these identified problems. Furthermore, information on a scientific approach to the refurbishment and/or replacement of worn tillage tools using locally available materials is lacking. This book evaluates the wear performance of developed cultivator tines in a tropical sandy loam soil in Southwestern Nigeria with a view to enhancing local tillage practices and improving the service life of cultivator tines used on Nigerian soils.Researchers and students working on wear resistance of tillage tools will find this book very useful. it will also assist tutors handling agricultural tillage and related topics in the faculties of agriculture and engineering technology

Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
