Book Synopsis An Assessment of Intercropping and Fertilization in Cassava - (Manihot Esculenta) Based Systems in the Kolli Hills, South India by : Tina Harms
Download or read book An Assessment of Intercropping and Fertilization in Cassava - (Manihot Esculenta) Based Systems in the Kolli Hills, South India written by Tina Harms and published by . This book was released on 2015 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is much interest in reducing risk, increasing yield and maintaining soil fertility and biodiversity in agriculture. The effects of intercropping cassava (M. esculenta crantz) with beans (Phaseolus spp), millet (E. coracana) or a bean-millet mixture with the use of various soil amendment treatments; manure, manure and synthetic fertilizer, synthetic fertilizer or mulch under a rainfed cropping system were investigated over a two year period in Kolli Hills, South India. Physical and chemical properties of soil, bean protein content, cassava leaf nutrients and starch content, and marginal rates of return were assessed. Results varied greatly across sites and seasons. Intercropping with millets significantly reduced crop yields in Mathyriolovo and Oleyur; mean yields in year one and two were higher when synthetic fertilizer and a combination of fertilizer and manure were applied; during year two, the greatest yield increase resulted from mulching. Intercropping with millets had both negative and positive impacts on soil: lowering available N, and exchangeable Mn, while showing increases in available P in various sites. When bean with millets were intercropped with cassava, there were significant increases in soil exchangeable Na, available P, EC, Cu and exchangeable K in comparison to other treatments. Manure resulted in a significant increase in soil pH, and a decrease in Zn; the addition of synthetic fertilizer resulted in an increase in soil EC in various sites. Results of principal component analysis (PCA) showed that soil Zn, clay content, CEC, Cu, pH and available K accounted for the greatest amount of variation in samples and the resultant soil quality index (SQI) for cassava production in the Kolli Hills. Economic analysis highlighted the great variation between site and seasons; fertilizer and manure plus fertilizer intercropped with millets or bean and millets having the highest marginal rate of return in year one, while sole cropping of cassava under a mulch treatment provided a positive return in year two. Based on soil properties, crop qualities and economics cassava based cropping systems may be improved by various intercropping systems and soil amendments; however, the great variation in soil, climate, availability of inputs and the needs of the smallholder farmer need to be considered prior to forming overall management recommendations.
Book Synopsis Root Interactions and Evaluation of Agroforestry and Intercropping Systems in Benin, West Africa by : Sigmund Johannes Lose
Download or read book Root Interactions and Evaluation of Agroforestry and Intercropping Systems in Benin, West Africa written by Sigmund Johannes Lose and published by . This book was released on 2003 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: About the book In West Africa, traditional smallholder fallow systems urgently need sustainable intensification while maintaining soil fertility. Agroforestry systems were propagated to attain these targets. Earlier work, however, had not shown the expected positive effects on yield of the interplanted staple crops due to shading as well as root competition for nutrients and water. From 1995 until 1999, within the frame of the special research programme 308 (1985-1999) "Adapted farming in West Africa" of the University of Hohenheim, root studies were carried out in Southern Benin using the profile wall method for direct root observation and destructive soil monolith sampling. To estimate sustainability of the various treatments, i.e. fertilised, annual and perennial alley cropping in comparison to local practice, and production systems, i.e. maize-cassava intercropping, cassava sole-cropping as well as alley vs. block arrangement of perennial leguminous trees, yield trends were calculated for the three central trial sites at different edapho-climatical ecozones. Additionally, to quantify the complex interactions in agroforestry as well as in intercropping systems, data were used in system process modelling to give quantification of sustainable land management.

Book Synopsis Cropping Systems by : Johanna G. Hodges
Download or read book Cropping Systems written by Johanna G. Hodges and published by . This book was released on 2016 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a discussion on the applications, management and impact of cropping systems. Chapter One reviews the possibility of using intercropping, especially strip intercropping, as an effective and economically efficient crop biofortification. Chapter Two evaluates phosphorus dynamics in the soil-plant system under different management practices in the semiarid land of Pampas, Argentina. Chapter Three focuses on long-term winter wheat cropping and it's influence on soil quality and yield stability. Chapter Four examines gender-based socio-economic characteristics of cassava farmers; gender-based climate change awareness of cassava farmers; gender-based cassava farmers' constraints to climate change adaptation and examines the factors influencing gender-based cassava farmers' choice of adaptation strategies in the study area. Chapter Five studies the increased soil fertility in a long-term rice-oilseed rape cropping system and its potential roles in reducing nitrogen inputs and in the environment.

Book Synopsis Designing, Modeling and Evaluation of Intercropping Systems in China by : Heike rzer
Download or read book Designing, Modeling and Evaluation of Intercropping Systems in China written by Heike rzer and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2011-07 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adjusting cropping systems in order to increase their efficiency is a global issue. High yield and sustainability are the catchphrases of production in the 21st century, and agricultural production has to solve the balancing act between ecology and economy. Solutions have to be detected spatially explicit and locally adapted and accepted in order to be implemented successfully. Taking the North China Plain as an example, the productivity of arable land needs to be further increased by applying strategies to reduce or avoid negative environmental effects. Yield increases might be possible by developing improved cropping strategies operated by cropping designs. Taking modeling and simulation tools into account back up the acceleration of research attainments and the understanding of cropping systems. The present thesis embraces the designing and modeling of such a potential cropping system, to wit strip intercropping. Thus, the main goals of the study were to analyze, design, evaluate, and in the end model intercropping.
