Span lang=EN-GB style='mso-ansi-language:EN-GB'It was concluded that cultural weed management techniques that enhance radiation capture by the crop were effective in suppressing weed growth and seed production and increasing crop yields and should be incorporated into smallholder farmer's production practices in a systematic manner as part of Integrated Weed Management and cropping system design.

Book Description
Weeds have been identified as the major agronomic problem associated with arable crop production in conservation agriculture systems. Manual weeding and hand pulling are by far the most common weed control methods used in maize production, whilst chemical weed control is relatively uncommon in Zimbabwe's smallholder farming systems. In Zimbabwe, the key to conservation agriculture revolves around weed control. An experiment was done to evaluate the effect of manual and chemical weed control strategies on (i) weed density and biomass, (ii) total labour requirements for weed control, (iii) maize biomass and grain yield and (iv) the economics of weed control. The trials were done at four sites in Zimbabwe's Highveld area in the 2007/8 rainy season. Results from the different sites show that weed abundance was not significantly affected by the different weed control strategies that were used in this study. However the different weed control strategies resulted in differences in labour requirements and economic returns. This study showed that using tank mixes of glyphosate and atrazine at planting is the most effective and economically feasible weed control strategy.

Book Description
Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Book Description
Nitrogen fixation by leguminous plants is especially important when farmers are trying to minimise fertilizer use for cost or environmental reasons. This second edition of the highly successful book, first published in 1991, contains thoroughly updated and revised material on the theory and practice of nitrogen fixation in tropical cropping systems.

Book Description
Maize is a staple cereal after wheat and rice. It is an important source of carbohydrate, protein, iron, vitamin B and minerals for many poor people in the world. In developing countries maize is a major source of income in resource-poor farmers. As maize is used both as silage and as crop residue and the grains of maize are usually used for food, starch and oil extraction industrially, the demand for maize is rising day by day. Therefore, it is imperative for improvement of maize to meet the increasing demand. This book entitled "Maize - Production and Use" highlights the importance of maize and the improved management approaches for improving the productivity of maize in the era of changing climate.
