Book excerpt: 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.

This book was released on 2009-09-23 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Download or read book Evaluating the Effect of Legume-maize Intercropping on Plant Growth, N2 Fixation, WUE, C Assimilation, Grain Yield and Microbial Diversity written by and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the effect of maize-legume intercropping on plant growth, N2 fixation, WUE, C assimilation and grain yield under field conditions in Eswatini. The 15N natural abundance and ureide assay were used to assess N2 fixation in the six test legumes (Bambara groundnut, cowpea, dry bean, groundnut, jack bean and soybean). Instantaneous water-use efficiency was estimated as the ratio of photosynthetic rate to stomatal conductance from gas-exchange measurements while the 13C natural abundance technique was used as an integrated estimate of WUE. The six test legumes obtained 39.06 – 70.19% of their N nutrition from symbiosis based on the 15N natural abundance technique, while the ureide assay showed that the legumes could obtain 16.46 – 55.79% of their N from symbiosis. The amount of N-fixed ranged from 12.66 to 66.57 kg ha-1 . In most instances, a high amount of N-fixed by legumes was accompanied by greater shoot DM and high grain yield, which indicates the importance of the symbiotic process in plant growth and grain yield. Plants that recorded high photosynthetic rates and leaf chlorophyll content also had greater WUE, and higher WUE was also associated with increased shoot DM and improved yields. The low shoot C:N ratio (12.67 – 21.44 g.g-1 ) of test legumes would support rapid decomposition. ERIC-PCR fingerprinting of isolates revealed high genetic diversity among the rhizobial symbionts of groundnut, jack bean and soybean from Eswatini. Phylogenetic analysis based on the 16S rRNA, housekeeping genes (atpD, dnaK, glnll and rpoB) and symbiotic genes (nifH and nodC) showed that the three legumes were nodulated by rhizobia belonging to the genus Bradyrhizobium. The groundnut microsymbionts were closely related to B. arachidis, B. iriomotense and B. canariense, while the jack bean and soybean microsymbionts were closely related to B. pachyrhizi and B. elkanii. Symbiotic characterization of bacterial isolates showed high variation in nodule number, nodule dry matter and shoot DM induced by rhizobia in their homologous hosts, name groundnut, jack bean and soybean. Some of the test isolates elicited higher relative symbiotic efficiency (RSE) than the commercial rhizobial strains, indicating that the indigenous rhizobia present in Eswatini soils can potentially be used in the development of inoculants. Interestingly, isolates which recorded high RSE clustered together in the single gene phylograms of the housekeeping genes and in the 16S rRNA phylogram. The findings of this study will assist in improving grain yield of maize in Eswatini through maize-legume intercropping.

Download or read book A Regional Investigation of In-season Nitrogen Requirement for Maize Using Model and Sensor-based Recommendation Approaches written by Laura Joy Stevens and published by . This book was released on 2014 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: N management for corn can be improved by applying a portion of the total N during the growing season, allowing for adjustments responsive to actual field conditions. This study was conducted to evaluate two approaches for determining in-season N rates: Maize-N model and active crop canopy sensor. Various sensor algorithms designed for making in-season N recommendations from crop canopy sensor data were evaluated. The effects of corn hybrid and planting population on recommendations with these two approaches were considered. In a 2-yr study, a total of twelve sites were evaluated over a 3-state region, including sites in Missouri, Nebraska, and North Dakota. In-season N recommendations were generally lower when using the sensor-based approach with Holland and Schepers (2012) algorithm than the model-based approach. This resulted in observed trends of higher partial factor productivity of N and agronomic efficiency for the sensor-based treatments. At specific sites, conditions leading to high levels of mineralized N becoming available to the crop during the growing season increased environmental and economic benefit of the sensor-based approach. The optimum N rate was estimated using a linear-plateau model. Compared to the sensor-based approach with the Holland and Schepers algorithm, the model-based approach more closely estimated the optimum N rate and erred by over-recommending N. Profit loss from the sensor with Holland and Schepers algorithm was greater when considering all sites collectively due to the greater cost of lost yield when N was under-applied, versus the lower cost of excess N when N was over-applied.

Download or read book Legumes for Soil Health and Sustainable Management written by Ram Swaroop Meena and published by Springer. This book was released on 2018-07-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable management of soils is an important global issue of the 21st century. Feeding roughly 8 billion people with an environmentally sustainable production system is a major challenge, especially considering the fact that 10% of the world’s population at risk of hunger and 25% at risk of malnutrition. Accordingly, the 68th United Nations (UN) general assembly declared 2016 the “International Year of Pulses” to raise awareness and to celebrate the role of pulses in human nutrition and welfare. Likewise, the assembly declared the year 2015 as the “International Year of Soils” to promote awareness of the role of “healthy soils for a healthy life” and the International Union of Soil Science (IUSS) has declared 2015-2024 as the International Decade of Soils. Including legumes in cropping systems is an important toward advancing soil sustainability, food and nutritional security without compromising soil quality or its production potential. Several textbooks and edited volumes are currently available on general soil fertility or on legumes but‚ to date‚ none have been dedicated to the study of “Legumes for Soil Health and Sustainable Management”. This is important aspect, as the soil, the epidermis of the Earth (geoderma)‚ is the major component of the terrestrial biosphere. This book explores the impacts of legumes on soil health and sustainability, structure and functioning of agro-ecosystems, agronomic productivity and food security, BNF, microbial transformation of soil N and P, plant-growth-promoting rhizobacteria, biofertilizers, etc. With the advent of fertilizers, legumes have been sidelined since World War II, which has produced serious consequences for soils and the environment alike. Therefore, legume-based rational cropping/soil management practices must support environmentally and economically sustainable agroecosystems based on (sequential) rotation and intercropping considerations to restore soil health and sustainability. All chapters are amply illustrated with appropriately placed data, tables, figures, and photographs, and supported with extensive and cutting-edge references. The editors have provided a roadmap for the sustainable development of legumes for food and nutritional security and soil sustainability in agricultural systems, offering a unique resource for teachers, researchers, and policymakers, as well as undergraduate and graduate students of soil science, agronomy, ecology, and the environmental sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Global crop production must substantially increase to meet the needs of a rapidly growing population. This is constrained by the availability of nutrients, water, and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles are the core of integrated approaches to solve this critical challenge. This special issue provides an international basis for revealing the underlying mechanisms of sustainable cropping systems to drive agronomic innovations. It includes review and original research articles that report novel scientific findings on improvement in cropping systems related to crop yields and their resistance to biotic and abiotic stressors, resource use efficiency, environmental impact, sustainability, and ecosystem services.
