Book excerpt: Corn or maize is a crop that originated in Mexico and has spread all over the world as a major food crop. Sustainable production of a corn field crop as grain corn for feed, food and biofuels, as well as sweet corn for fresh market or processing, and as silage for high energy sources, requires scientific management of nutrients along with several other crop management practices such as proper plant population density, timely seeding and harvesting, soil water, weeds and pests control. Corn has become the major item in the diet of many tropical peoples, the main grain used for animal feed in temperate regions, as well as new stocks for many other purposes including recently used as feedstock for biofuels. Rapid expansion of grain based ethanol production in North America, has already caused concern about future food and feed supplies. This important book gathers the latest research from around the world in this dynamic field.

Download or read book The Solar Corridor Crop System written by C. LeRoy Deichman and published by Academic Press. This book was released on 2019-06-12 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Solar Corridor Crop System: Implementation and Impacts presents a case-study format on the planning and implementation of alternative cropping systems designed to maximize incident sunlight and bio-support of all crops in a rotation system. The book describes the basic component of the system, an increased access point of incident sunlight between each row or pairs of rows that enables a more uniform vertical distribution of incident sunlight to chloroplasts within the entire corn leaf canopy. While the production environment and environment specific genetics determine the performance potential of this principle, by maximizing the principles that light is basic to crop yield, a solar corridor ultimately contributes to increased grain yield. Written by experts who were integral in the development of solar corridor systems, and providing real-world examples of the methods, challenges and future prospects, this book will be valuable for those seeking to increase yield-per-acre through both primary and cover-crops. - Introduces readers to the concept of alternative row-cropping and its implementation - Presents real-world experience, including challenges and solutions - Encourages research in maximizing photosynthesis impact on crop yield

Available in PDF, EPUB and Kindle. Book excerpt: For the past 20 years, the first edition of this text has been widely cited as authoritative academic reference. The latest edition continues the tradition set by the original book, and covers weed science research that has been published since 1980. This book aims to reduce the instance of research duplication—saving scientists and supporting institutions time and money. Not only does the second edition of Weed Crop Competition review, summarize, and combine current research; it critiques the research as well. This text has the potential to accelerate advancements in weed crop competition, which remains an important factor that affects crop yields. Scientists in foreign countries where access to literature is often limited or nonexistent, will find the information in this text invaluable. Weed scientists, crop scientists, plant ecologists, sustainable agriculturists, and organic agriculturists will be well-pleased with this long overdue and much needed new editionWeed Crop Competition provides a unique reference that reviews, summarises and synthesizes the literature published concerning research on this topic. The first edition has been one of the most frequently cited sources in weed science for the past 20 years. The second edition covers the significant body of literature that has been published since 1980. Originally intended to survey existing research, the intent of the book is to reduce the instance of research duplication, thus saving scientists and their institutions time and money, and expediting advancements in weed crop competition, an important factor affecting crop yields. Scientists in foreign countries where access to the literature is often limited or non-existent, find the information an invaluable resource. This long overdue and much needed new edition rejuvenates the tradition set by the original book.

Download or read book The Influence of Plant Population Nitrogen Rate and Hybrids on Pro Duction and Quality of Corn for Silage written by D. G. Cummins and published by . This book was released on 1975 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in varied experiment at different locations showed that management markedly influenced corn production for silage. Work was conducted to relate these various management factors to silage production in an experiment repeated across locations. Studies were conducted at two locations in the Coastal Plain region, and at one locative each in the Peidmont, Limestone Valley, and Mountain regions. The objective were: (1) to determine the effects of plant populations, nitrogen (N) rates, and hybrids on production and quality of corn for silage; and (2) to relate these results to those in previous experiments. The results can be summarized as follows: 1. Maximum yields were produced with populations of 28,000 plants/acre under optimum management, but ar lower populations when soil moisture was limiting. However, the higher plant populations never reduced yields compared to lower populations, so even in the case of droughtty soils the higher population of 28,000 plants/acre could be planted to take advantage of seasons with good rainfall distribution. 2. Forage quality was maintained ar populations of 28,000 corn plants/acre. The general trend, although not always significant, was for digestibility (IVDMD), percentage ears, and percentage protein to decrease and percentage stalks and fiber to increase in the forage with a population increase. 3. Nitrogen rates of 150 pound/acre produced maximum yields (...).
Download or read book Management Practices for Corn Producers Implementing Early Planting as a Production Strategy written by Matthew W. Hock and published by . This book was released on 2017 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Producers choosing to implement an early corn planting management strategy often experience several yield limiting biotic and abiotic factors. Field variability, flooding, sub-optimal soil temperatures which leads to poor nutrient uptake, delayed emergence and reduced root growth can limit grain production. Three separate experiments were conducted to address some of the negative effects associated with early corn planting. Experiment 1 evaluated flooding effects on several morpho-physiological traits including root system architecture during early crop development. Hybrids (DKC 6208, Pioneer 1197) were flooded at planting (V0) and growth stages V1, V2, V3 for 0, 6, 12, 24, 48, 96 hours. Plants flooded at V0 11% suffered the steepest decline in collar height. Plants flooded at V2 10% were more susceptible than plants flooded V1 4%. Overall, there was a linear decline in nutrient concentration if flooding occurred at planting. Tissue Na levels were the most affected by flood duration and K was the least affected. Experiment 2 evaluated biologic compounds developed to increase immobile nutrients P and K to improve fertilizer use efficiency and provide slow developing roots essential nutrients. The effectiveness of microbial products (B-300, QR, Mammoth, EM 1) with/without starter fertilizer influenced yield, emergence, plant growth, and nutrient uptake. Biologic seed treatments compared to the control, resulted in a positive yield advantage for all treatments. Yields ranged from 37 to 48% higher if biologic compounds were applied. On average, yields increased from 26 to 38% after starter fertilizer was added to the biologic compounds. Phosphorus levels at VT were significantly higher for QR and K content was higher for B300, SF-B300, QR, Mamm, and SF-Mamm compared to the control. Experiment 3 addressed soil physical/chemical properties affecting plant development and there yield plant density relationship. On average, yields significantly increased 40% as plant population increased from 49,400 to 103,740 plants ha−1 . Based on the quadratic model agronomically yields would be highest at 61,360 plants ha−1 . Correlation analysis among yield and soil physical and chemical properties revealed positive correlations for grain yield, sand% (r 2 = 0.42), soil K (r 2 = 0.17) soil Na (r 2 = 0.46), and soil P (r 2 = 0.49).
