This book was released on 2011-03-23 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents a method to assess yield performance of dual-purpose cowpea types for human consumption and to reveal potentials for further improvement of its use as leafy vegetable. Eleven cowpea accessions with different genetic background and sample status were chosen from AVRDC’s working collection in Arusha, Tanzania. Among them, dual-purpose cowpeas like Dakawa, Ex Iseke and Ngoji were present that the center has been distributing to local farmers. Multi-location trials in typical cowpea production environments were established both on farm and on station in the regions Arusha, Dodoma, and Kilimanjaro in Tanzania and in Eastern Region, Uganda during the short and long rainy season 2007 and 2008, respectively. Young, tender leaves were picked in successive leaf harvests about every and two weeks until the plants did not produce further leaves. Cowpea seeds were harvested when pods reached 80% maturity. Data of yield parameters were analyzed with analysis of variance (ANOVA), stability analyses were carried out according to the dynamic and static concepts. Reliability of leaf and seed yield performances were calculated based on the probability of outperformance of local check cowpeas that were previously recommended by farmers and extension workers in informal group sessions. Through NIRS, crude protein and iron contents were assessed in leaves obtained from the second leaf harvests at the different locations and from up to subsequent leaf harvests. Dual-purpose utility for smallholders was assessed through (i) an index of superiority (Si), in which reliabilities of leaf yield across repeated leaf harvests and seed yield were weighed and combined to overall yield benefit of the ith accession, (ii) effective plot length for nutritional component XY, to calculate the length of a plot (in m) that needs to be planted to sustain a five-head household for ten days with a recommended amount of nutrients, and (iii) responsiveness (Resp), reflecting changes of leaf yield (compensation) relative to changes in seed yield (sensitiveness) if harvesting frequency was intensified. Performance of single leaf yields was strongly influenced by environmental factors and, only in Arusha, accession-specific. Interactions between yield reliability and stability were site-specific. Overall, test-accessions achieved higher reliabilities in seed yield than in leaf yield. Only in the on-station trial in Eastern Region, accession IT82D-889, and in the on-farm trial in Kilimanjaro, ILRI11114 and Ex Iseke showed leaf yield reliabilities above 0.50. Iron content in cowpea leaves was highly dependent on environmental influences and varied from 157.4 mg kg-1 to 286.1 mg kg-1. Leaf CP had a broad-sense heritability of 0.87. Across accessions and environments the mean leaf CP content ranged from 37.4% of DM (IT93K-2045-29) to 33.9% of DM (Sudan). CP and leaf dry matter (DM) yield had significantly negative correlation coefficients between. Means of effective plot length for crude protein and iron varied by more than 50% across environments. Although CP, in contrast to iron, was genetically determined, its impact on differences in effective plot length was negligible as well, as differences in production of leaf DM per m2 were by far larger among accessions than those of CP contents. It was recommended to favor accessions with short effective plot lengths and higher CP contents in leaf yields over those with short effective plot lengths and low CP contents. In contrast to determinate cowpeas, indeterminate types increased their DM gain in aerial plant parts of leaf-harvested plants relatively to unharvested plants. Indeterminate cowpeas responded with high leaf yield increases if leaves were picked twice a week. Consequently yields of total edible DM of these plant types, comprising added seed and leaf yields, increased with intensification of leaf-harvesting frequency from once to twice a week. Determinate plant types yielded highest in total edible DM when only seed was harvested or in less intensive leaf-harvesting scenarios. Accessions with favorable responsiveness, reflecting leaf yield changes relative to seed yield changes under intensified leaf-harvesting frequency, were Sudan, ILRI11114, and IT93K2045-29. In contrast, Resps of SAM45 and ILRI15742 were poorest. Traits have to be identified that could explicitly improve Resp of cowpea types. Improving quantitative yield parameters should not result in quality decrease. The dual-purpose characteristics of local checks were mainly superior to the eleven test-accessions pointing to a demand on improved leaf yield performance that is not merely total leaf yield amount but also the continuance during repeated leaf harvesting. By the proposed method the status quo of a defined location, i.e. site-specific demands on germplasm, can be included in the analysis, serving as benchmark for improvement if the local check is chosen carefully. Since single leaf yields are the results of fairly complex and dynamic interactions between plant physiological processes and environmental conditions it is essential to conduct participatory variety selection and plant breeding trials for dual-purpose assessments in target environments and not ex situ.

Download or read book Dry Beans and Pulses written by Muhammad Siddiq and published by John Wiley & Sons. This book was released on 2012-08-29 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common beans and pulses are diverse food resources of high nutritional value (protein, energy, fiber and vitamins and minerals) with broad social acceptance. These legume crops demonstrate global adaptability, genotypic and phenotypic diversity, and multiple means of preparation and dietary use. Beans and pulses are produced in regions as diverse as Latin America, Africa, Asia, and North America, and on a scale similar to some other crops, such as wheat, corn, rice and soybeans. Numerous factors influence utilization, including bean type and cultivar selection, cropping environment and systems, storage conditions and handling infrastructure, processing and final product preparation. Nutrient content and bio-availability are dramatically influenced by these conditions. In recent years, beans and pulses have been cited for imparting specific positive health potentiating responses, such as hypocholesteremic response, mitigation of diabetes and colonic cancer, and weight control. Enhanced dry bean utilization focused on improved dietary health is an opportunity within both subsistent and developed populations. This book provides a contemporary source of information that brings together current knowledge and practices in the value chain of beans/pulses production, processing, and nutrition. It provides in-depth coverage of a wide variety of pertinent topics including: breeding, postharvest technologies, composition, processing technologies, food safety, quality, nutrition, and significance in human health. An experienced team of over 25 contributors from North America, Asia, and Africa has written 15 chapters, divided into three sections: Overview, production and postharvest technologies of beans and pulses Composition, value-added processing and quality Culinology, nutrition, and significance in human health Contributors come from a field of diverse disciplines, including crop sciences, food science and technology, food biochemistry, food engineering, nutritional sciences, and culinology. Dry Beans and Pulses Production, Processing and Nutrition is an essential resource for scientists, processors and nutritionists, whatever the work setting.

This book was released on 2021-01-18 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 20 million childhood deaths occur every year due to the micronutrient deficiency and diet-related non-communicable diseases (cardiovascular diseases, cancers, chronic respiratory diseases and diabetes). The United Nations (UN) recently announced that the increase in chronic, non-communicable diseases has resulted in 36 million deaths around the world annually, claiming more lives than all other causes combined. These chronic diseases are not isolated to developed countries and are even more pronounced in the developing world. Such chronic illnesses have caused far more deaths than infectious diseases throughout the world (except Africa) in recent years. Therefore, enrichment of micronutrients in staple food crops is of paramount importance for the nutritional security in our world. Biofortification is the development of micronutrient- and/or vitamin-rich crops using traditional crop improvement practices as well as modern biotechnology tools. It is a more sustainable and cost effective method than food supplementation, fortification and diet diversification. This work consolidates available information on the different aspects of breeding for improved nutrition of pulses. An overview of entire pulses based on their nutritional profile is given so that audience can find the desired information easily. Food legumes are the active ingredients in many gluten-free food products and there is a continuous rise of the use of pulses flour in milling and baking processes. Our book sheds light on recent efforts and the underlying constraints of meeting the public demand. We believe this work provides the basic information for anyone interested in biofortification and stimulate further research to meet this unique challenge.
