Book Synopsis Urea-ammonium Nitrate Fertilizer Placement Effects on Corn (Zea Mays L.) N Utilization and Grain Yield as Influenced by Irrigation by : Jon Michael Carson
Download or read book Urea-ammonium Nitrate Fertilizer Placement Effects on Corn (Zea Mays L.) N Utilization and Grain Yield as Influenced by Irrigation written by Jon Michael Carson and published by . This book was released on 2015 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen use efficiency (NUE) and nitrogen (N) management practices have been an increasing concern among corn (Zea mays L.) producers. The objective of this study was to assess the placement distance of UAN and measure total N uptake on corn grain yield as affected by irrigation. Field trials were conducted in 2011 and 2012 at the Plant Science Research Center, Mississippi State, MS. Placement distance and irrigation influenced both total N uptake and grain yield results during both years of this study. Total N uptake and corn grain yield results were derived from plant samples and harvest data. Overall results from this study indicate increasing placement distance from the center of the planted row resulted in a decrease in total N uptake and grain yield. Results also show the subsurface banded treatment resulted in a greater N uptake and grain yield.

Book Synopsis Microorganisms for Green Revolution by : Deepak G. Panpatte
Download or read book Microorganisms for Green Revolution written by Deepak G. Panpatte and published by Springer. This book was released on 2017-12-07 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses basic and applied aspects of two nexus points of microorganisms in agro-ecosystems, namely their functional role as bio-fertilizers and bio-pesticides. Readers will find detailed information on all of the aspects that are required to make a microbe “agriculturally beneficial.” A healthy, balanced soil ecosystem provides a habitat for crops to grow without the need for interventions such as agro-chemicals. No organism in an agro-ecosystem can flourish individually, which is why research on the interaction of microorganisms with higher forms of life has increasingly gained momentum in the last 10-15 years. In fact, most of plants’ life processes only become possible through interactions with microorganisms. Using these “little helpers” as a biological alternative to agro-chemicals is a highly contemporary field of research. The information presented here is based on the authors’ extensive experience in the subject area, gathered in the course of their careers in the field of agricultural microbiology. The book offers a valuable resource for all readers who are actively involved in research on agriculturally beneficial microorganisms. In addition, it will help prepare readers for the future challenges that climate change will pose for agriculture and will help to bridge the current gaps between different scientific communities.

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.

Book Synopsis Evaluation of Soil Parameters and Diagnostic Tools to Assess Nitrogen and Sulfur Response in Corn and Wheat by : Tyler Eugene Husa
Download or read book Evaluation of Soil Parameters and Diagnostic Tools to Assess Nitrogen and Sulfur Response in Corn and Wheat written by Tyler Eugene Husa and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulfur fertilization is receiving more interest, with sulfur deficiencies showing up in crops including corn and wheat. Decreased atmospheric deposition and higher yields have driven the need for sulfur fertilization. Two studies were conducted to evaluate nitrogen (N) and sulfur (S) responses. The objectives of the first study were to assess the effects of nitrogen sources and sulfur rates on yield, nutrient uptake, and nutrient use efficiency terms on corn (Zea mays L.) production. Nitrogen and S concentrations in corn biomass and grain were evaluated, and N and S use efficiency indicators were calculated at five locations in 2019 and 2020. The experiment was set up in a randomized complete block design with seven treatments and four replications. Treatments included a control with no fertilization, three fertilizer treatments evaluating sulfur rates, and three evaluating N sources. Fertilizer treatments were balanced to 202 kg N ha−1. Fertilizer treatments were sidedress applied on the soil surface before V6 growth stage. Organic matter greatly impacted nutrient use efficiency indicators, including agronomic efficiency (A.E.), apparent recovery efficiency (R.E.), and internal efficiency (I.E.). The impact of S rate and N source on yield was not statistically significant across locations, but yields at locations 1 and 2 trended higher with added sulfur fertilizer at increments of 17, 31, and 52 kg S ha−1. Nitrogen fertilizer resulted in a significant increase in post-harvest soil nitrate compared to the control, but there was no significant difference between N source and S rate. The second study focused on wheat (Triticum aestivum L.) response to S affected by soil characteristics. The objectives of this study were to evaluate plant uptake of S and N with added S fertilizer and the effect of soil parameters on wheat response to S.A greenhouse study was conducted utilizing 15 soils from Kansas and Nebraska. Fertilizer treatments included Urea Ammonium Nitrate (UAN) (28-0-0; N-P2O5-K2O) at 0.99 mL UAN pot−1 (300 kg N ha−1) to all pots, and half of those pots had micronized elemental sulfur (0-0-0-50S; N-P2O5-K2O-S) at 0.19 mL (100 kg S ha−1). All fertilizers were topdress applied using a metered pipet. A randomized complete block design was utilized using three replications for each N and N plus S fertilizer treatment. Pre-fertilization soil samples were analyzed for properties including Soil Organic Matter (S.O.M.), Cation Exchange Capacity (C.E.C.), pH, soil texture, phosphorous, potassium, zinc, total carbon, total nitrogen, and soil test sulfur. The average whole plant wheat sulfur uptake (WPU-S) was increased with the application of sulfur fertilizer for many soils in this study. The main soil variables determining plant response to S fertilizer were soil test phosphorus, soil organic matter, cation exchange capacity, and sand content. Higher soil test phosphorus (STP) and sand content contributed to greater plant response and uptake of sulfur from applied S fertilizer. In contrast, higher soil organic matter and cation exchange capacity resulted in smaller plant response to applied S fertilizer. Thus, the traditional soil test S showed a low correlation with plant response in our study. These results suggest that a more accurate prediction of wheat response to S fertilizer may be accomplished considering multiple soil parameters.
