Book Influence of Foliar Sulfur  Chloride and Nitrogen on Winter Wheat Grain Yield and Total Nitrogen  Triticum Aestivum L

Download or read book Influence of Foliar Sulfur Chloride and Nitrogen on Winter Wheat Grain Yield and Total Nitrogen Triticum Aestivum L written by Sulochana Dhital and published by . This book was released on 2013 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimum use of nitrogen (N) is a key component in improving wheat grain yield and quality. The combined effect of other nutrients with N can have a positive impact on crop production. Using sulfur (S) and chloride (Cl) in wheat and other cereals has received increased attention in recent years. Foliar S and Cl can assist in optimizing wheat yield and total N, especially in sandy soils with low organic matter where deficiencies are expected. Winter wheat studies were conducted for 3 site-years at Lake Carl Blackwell (LCB) and Lahoma (LAH) in the fall of 2011 and 2012 to evaluate the effect of flag leaf applied foliar N, S and Cl on winter wheat grain yield and grain N. Two N rates, 10 and 20 kg N ha−1, as urea triazone (N-SURE, 28-0-0) and urea ammonium nitrate (UAN, 28-0-0) were foliar applied. Treatments included foliar application of gypsum (6 kg S ha−1) and calcium chloride at a rate of 10 kg Cl ha−1 applied with the help of CO2 backpack sprayer. Results showed total grain N increased with increasing preplant N rate at LCB and LAH. With increasing preplant N, a linear increase in yield was observed at LAH and a quadratic increase in yield at LCB. There was no response to foliar N, Cl and S at both locations. This study indicated that S and Cl fertilization did not increase yield and protein.

Book Agriculture and the Nitrogen Cycle

Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.

Book Nitrogen and Sulfur Effects on Hard Winter Wheat Quality and Asparagine Concentration and Survey of Kansas Soil Sulfur Conditions

Download or read book Nitrogen and Sulfur Effects on Hard Winter Wheat Quality and Asparagine Concentration and Survey of Kansas Soil Sulfur Conditions written by Tara Leanne Wilson and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil sulfur (S) deficiency is becoming increasingly common throughout the U.S. due to The Clean Air Act of 1990; S deficiency is typically found in high sand and low organic matter soils and looks very similar to nitrogen deficiency with stunted growth and chlorosis. Over application of N when there is a S deficiency has shown to be detrimental to wheat quality. Sulfur deficiency is detrimental to baking quality due to its effects on formation of disulfide bonds. These bonds are formed from the sulfhydryl groups of cysteine, which influence viscoelasticity of dough. Soil S deficiency can also lead to an increase of free asparagine concentration which indicates acrylamide forming potential of baked products. Acrylamide is a potential carcinogen; S fertilization has been shown to decrease acrylamide forming potential in wheat flour. Therefore, the objectives of this study were to: i) determine the effect of genotype, N, and S fertility on overall wheat quality and rheological characteristics; ii) determine the typical range of asparagine in wheat grain in Kansas: and iii) determine the influence of S availability in soils on asparagine in wheat grain. In the first study we found that in a soil with low S availability, S fertility significantly increased overall grain quality and rheological characteristics as well as increasing yield. Protein composition was evaluated by the ratio of total polymeric/ total monomeric protein using high performance liquid chromatography. In both years, the ratio of polymeric to monomeric protein was increased by sulfur fertilization. Solvent retention capacity (SRC) was evaluated using the whole grain lactic acid-sodium dodecyl sulfate solvent retention test (lactic acid- SDS SRC). In 2018, S application increased the SRC from 217% to 308%. Sulfur application increased average farinograph stability from 9.2 min to 14.6 min. Farinograph stability was effectively predicted by the SRC test (R2=0.78). Free asparagine concentration decreased significantly in both years across all genotypes when S was applied. Although, in Chapter 2 we found that poor wheat quality in a S deficient soil was increased with S fertilizer application, we did not find a strong correlation between available S in the soil and wheat quality or free asparagine concentration in Chapter 3. In 2018 a S sufficient location, Ashland had the highest free asparagine concentration (37 [mu]mol/g) which was likely due to hot dry weather during grain fill. Thus, further investigation of factors influencing free asparagine in winter wheat is necessary for us to have a better understanding of how to decrease the risk of elevated levels. Information from this study will help winter wheat producers in the Great Plains diagnose sulfur deficiency and determine best practices for increasing grain quality and decreasing free asparagine concentration.

Available in PDF, EPUB and Kindle. Book excerpt: Sulphur (S) plays a pivotal role in various plant growth and development processes being a constituent of sulphur-containing amino acids, cysteine and methionine, and other metabolites viz., glutathione and phytochelatins, co-factor of enzymes which contribute to stress repair and amelioration of heavy metal toxicity. Besides, a number of S-containing components are biologically active and, thus, a source for use as medicinal value. The basic global issue before the agricultural scientist and world community is to evolve cultivars and develop methodologies for efficient use of inputs to enhance agricultural productivity. This is particularly true of the developing countries which are going to see maximum rise in population with changing food demands and declining availability of land. Amongst the inputs, nutrients play a crucial role. The major requirement is for N, P and K followed by several micro-nutrients. In this context reports of world-wide S deficiency in the agricultural systems are relevant. The reasons are many. Broadly speaking reduction inS emission, use of S-free N, P and K fertilizers and higher biomass production contributed the maximum. Despite the need for sulphur as an essential plant nutrient and the substantial returns expected from its use, very little attention has been given to fill the gap between supply and demand of S.

Book Evaluation of Soil Parameters and Diagnostic Tools to Assess Nitrogen and Sulfur Response in Corn and Wheat

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.

Book The Impact of Sulphur on the Breadmaking Quality of Canadian Western Red Spring Wheat in Western Canada

Download or read book The Impact of Sulphur on the Breadmaking Quality of Canadian Western Red Spring Wheat in Western Canada written by Christopher J. H. Unger and published by . This book was released on 2002 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada Western Red Spring (CWRS) wheat (Triticum aestivum L. cv. AC Barrie) was grownl at twelve locations, over two growing seasons across western Canada, to study the impact of S fertilization on grain yield and quality of wheat. Treatments consisted of two rates of fertilizer S (0 and 20 kg ha-l) as ammonium sulphate and two rates of fertilizer N (26 and 100 kg ha-l) as urea in a factorial design. Soil and plant tissue tests were also evaluated for their ability to predict grain S concentration, grain N:S ratio, total S accumulation in the plant, and grain quality responses to S fertilization. Analysis of grain for total S, N, and N:S ratio accurately predicted the concentration of S, N, and N:S ratio in flour. Grain S concentration and N:S ratio were weakly correlated with both absolute and relative grain yield. Grain S concentration was strongly and positively correlated with loaf height, loaf volume, and oven spring; grain N:S ratio was negatively, but more weakly, correlated with these baking parameters. The improvements in baking quality were accompanied by an increase in dough extensibility and reduction in dough strength. Grain S concentration was positively correlated with dough extensibility and negatively correlated with maximum dough resistance, mixograph peak time, and work input to peak. Grain N:S ratio was negatively correlated with dough extensibility and positively correlated with maximum dough resistance and work input to peak. The improvements in baking and dough quality were associated with changes in the protein composition of flour. Grain S concentration was positively correlated with the proportion of soluble glutenin and negatively correlated with the ratio of insoluble to soluble glutenin in flour. Grain N:S ratio was negatively correlated with the proportion of soluble glutenin and positively correlated with the ratio of insoluble to soluble glutenin in flour. Sulphur fertilization increased grain yield at two of seven sites used for breadmaking quality evaluation. Application of S fertilizer also frequently improved the breadmaking quality, dough quality, and flour protein composition of wheat at four of these seven sites. All four sites where grain quality improvements were observed contained 40 kg SO4-S ha-l prior to fertilization, a concentration of soil S regarded as marginally sufficient for grain yield. Also, at these four marginal S sites, the S concentration and N:S ratio of plant tissue samples collected at 50 % heading was 0.15 % S and l7:1, respectively. Sulphur fertilization increased the concentration of S in grain and reduced the N:S ratio in grain at all marginal S sites. The improvements in grain S nutrition were accompanied by significant improvements in loaf volume at two of the four marginal S sites when S fertilizer was applied in combination with 26 or 100 kg N ha-l, and at one more site where 100 kg N ha-l was applied. Sulphur fertilization increased loaf height and oven spring at three of the four sites. Application of S fertilizer also significantly increased dough extensibility at all four marginal S sites and reduced maximum dough resistance and mixograph peak time at three of four sites. Mixograph peak time was significantly reduced at the other marginal S site only in the presence of 100 kg N ha-1. Furthermore, S fertilization reduced the viscoelastic ratio and mixograph work input to peak at all four marginal S sites. Sulphur fertilization increased the proportion of soluble glutenin in flour and reduced the ratio of insoluble to soluble glutenin in the flour at three of four marginal S sites. Sulphur fertilization in the presence of 100 kg N ha-1 only, increased the proportion of soluble glutenin in flour and reduced the ratio of insoluble to soluble glutenin in the flour at the other marginal S site. At the three sites where soil SO4-S concentrations were 40 kg ha-l, no yield and few breadmaking quality improvements were observed in response to S fertilization. For these high S sites, S fertilization did not increase the S concentration in grain at any site and reduced the N:S ratio in grain at only one site. At all four sites where grain contained - 0.17 % S and an N:S ratio 17:1, quality improvements due to S fertilization were consistently observed. At all three sites where grain contained S concentrations >-0.17 % S and N:S ratios
