Book excerpt: Understanding factors underpinning the variation in nitrogen (N) utilization efficiency (NUtE) [i.e., grain yield per unit of N uptake at maturity] is critical to direct future breeding and agronomic management strategies in wheat. However, no study has summarized changes in wheat NUtE across a wide range of environments. Further, the conservative behavior of producers to intensify management practices may have been contributing to the yield stagnation in the US southern Great Plains. Our goals were to: (i) perform a synthesis-analysis using published data to study NUtE in wheat, and (ii) conduct field studies to investigate the influence of genotype, environment, and management on grain yield and nutrient uptake. Results from our synthesis-analysis (n=529) showed a positive and curvilinear relationship between grain yield and NupMAT, indicating that opportunities to enhance yield through improving NUtE would only be possible at greater-than-average yield and N uptake levels. By measuring the effects of other reported variables on the residuals of the relationship between NUtE and N uptake, we observed that the variability in NUtE at particular levels of N uptake was greater for fall- than for winter-sown wheat, but it was similar for all wheat classes. The negative correlation between grain protein concentration and the residuals indicated a challenge to increase yield through improving NUtE with no penalties in grain protein. We conducted two field research experiments at difference sites during the 2015-16 and 2016-17 growing seasons in Kansas. In our experiment 1, we conducted on-farm experiments across three locations and two growing seasons in Kansas using 21 modern winter wheat genotypes grown under either standard (SM) or intensified management (IM) systems. Results showed that across all sites-years and genotypes, the IM increased yield by 0.9 Mg ha−1 relative to the SM. Even in the lowest yielding background condition, the IM outyielded SM, and expectedly, the yield response to IM increased with the achievable yield of the environment. The yield response of genotypes to IM was related to the responses of biomass between the two management systems rather than harvest index, strongly driven by improvements in grain number while independent of changes in grain weight, and related to improvements in N uptake. In our experiment 2, we evaluated the partial contribution of 14 management practices on grain yield and the accumulation of N, P, K and S during the growing season using a single bread-wheat genotype grown under four site-years. Fungicide was the main treatment affecting yield and nutrient uptake. Overall, all nutrients were accumulated at a similar proportion at each growth stage relative to their respective accumulation at the end of the season. Shoot concentration for IM seemed to maintain higher concentration of nutrients as compared to the SM control during the growing season. This was emphasized by the significant increase in nutrition indices for N and S from SM to IM control, indicating possible luxury uptake under IM. Hence, crop intensification strategies may alter nutrient uptake at the end of season, but will not affect timing and rate of uptake during the growing season.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The grain yield of winter wheat (Triticum aestivum L.) increased over time through plant breeding, and preliminary research suggested that yield response to fertilizer differs in modern versus historical genotypes. However, this response is not universal. We hypothesize selection for yield may have unintentionally modified the dynamics of nutrient uptake and partitioning in the plant. Thus, our objectives were to identify the key shifts in crop phenotype, in above-ground biomass and in dynamics of nutrient uptake and partitioning during vegetative and reproductive phases in response to selection for yield and to in-furrow fertilizer. Field experiments were conducted in four Kansas environments in a factorial trial combining eight winter wheat varieties released between 1920 and 2016, and two fertilizer practices (control versus 112 kg ha−1 in-furrow 12-40-0-10-1). Grain yield and grain N-removal increased non-linearly with year of release (YOR), with greater increases between 1966 and 2000. In-furrow fertilizer increased yield in ~300 kg ha−1 with no variety x fertility interactions. Grain protein concentration (GNC) related negatively to yield, and the residuals of this relationship were unaffected by YOR. Yield increase in semi-dwarf varieties were associated with shorter vegetative period and longer grain filling period, and more kernels m−2 derived from more kernels head−1. Historical varieties were taller, had thinner stems, and allocated more biomass to the stem than semi-dwarf varieties. At grain filling and maturity, shoot biomass was similar among varieties but semi-dwarf varieties allocated more dry matter to the kernels, suggesting that increases in yield derived from greater harvest index (HI) rather than greater biomass. Whole plant nutrient concentration negatively related to whole plant biomass and increased over decades for N, P, and S and decreased for K. In-furrow fertilizer increased the concentration of all nutrients. Grain-N, P, K, and S uptake increased from historical to semi-dwarf varieties; thus, nutrient HI increased with YOR, with greater increases between 1966 and 2000. Nutrient HI decreased with in-furrow fertilizer as the fertilizer increased biomass allocation to the vegetative tissues more than to the grain. Nutrient allocation rate to the head related positively to whole plant uptake rate, and YOR increased the head allocation rate for N, K, and S. There were positive and significant relationships between NHI and the HI of P, K, and S. Whole plant N uptake and P, K, and S uptake were also positively related, with ratios of 9.2, 1.1, and 15.4 for N:P, N:K, and N:S. Direct selection for grain yield modified the dynamics of nutrient uptake and partitioning over time, with semi-dwarf varieties allocating more N, P, K, and S to the grain. The ability of modern varieties to allocate more biomass and nutrients to the grain, coupled to an early maturity and longer grain filling period, increased grain yield and grain N-removal over time. However, increases in yield were greater than those in N-removal, reducing GNC. In-furrow fertilizer increased grain yield, biomass, and grain N, P, K, S uptake; nonetheless, the lack of variety x fertility interaction suggested variety response to fertility was similar.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat yields are variable in dryland environments due to the erratic weather regime and the consequent conservative management practices adopted by producers, leading to large yield gaps. Our objectives were to disentangle management x genotype interactions and identify management practices associated with increased wheat yield in dryland Kansas environments. Producer-reported yield and management data were collected from 656 commercial fields during the 2016-18 harvest seasons, including 43 management practices, five weather, and two soil variables. Grain yield ranged from 0.3 to 7.1 Mg ha−1 with yield gap averaging 44%. Foliar fungicide, nitrogen (N) rate, and method were the most common management strategies to affect yield. Two field experiments were conducted during 2018, 2019, and 2020 in several Kansas environments. In experiment one, we evaluated the grain yield response of four commercial wheat varieties to six different management intensities in six environments. Across environments and genotypes, managing for the yield potential increased yield by 1.4 Mg ha−1 (30%) as compared to the farmer practice. Aboveground biomass and kernel number related more strongly to yield than harvest index and kernel weight. Experiment two evaluated the colimitation of nitrogen (N) and sulfur (S) to wheat yield and its effects on N and S use efficiencies (and its components of uptake and utilization) in eight environments. Across environments, wheat grain yield increased with increases in N rate; however, S application only increased grain yield at two environments. Minimum N and S uptake to maximize yield at 5.7 Mg ha−1 was 120 and 7 kg ha−1. Nitrogen limitation impacted S use efficiency and vice versa, and the limitation of both nutrients increased the wheat yield gap. This research identified several genotype x management practices associated with wheat yield in commercial and experimental settings, and reinforced the need for integrated management practices according to site-specific limitations to improve wheat yields.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An effective nutrient management plan is essential for optimum wheat (Triticum aestivum) yields. The objectives of the first study were to: i.) evaluate changes in concentration of nitrogen (N), phosphorus (P), potassium (K), sulfur (S), copper (Cu), manganese (Mn), and zinc (Zn), within separate plant parts, throughout the growing season, ii.) evaluate the uptake pattern and redistribution of each of these nutrients within the plant throughout the season, and iii.) evaluate the impact of micronutrient and S fertilization on concentration and uptake of nutrients and the potential use of fertilization for biofortification. Three locations were established and sampled every 7 to 10 days during the spring. Samples were divided into leaf, stem, head, spike and grain fractions and analyzed for nutrient concentration. Concentration levels tended to decrease throughout the season in non-grain plant fractions and stay relatively constant in the grain. Harvest grain concentration of Zn was significantly higher with micronutrient fertilization at all locations, suggesting the possibility of Zn biofortification through fertilization. S, Cu, and Zn showed nutrient accumulation increases in all plant fractions until the time period around anthesis (Feekes 10.5.1), at which point leaf and stem fractions decreased in total accumulation while nutrients were remobilized to the grain. N, P, K and Mn showed a similar trend although timing of remobilization varied between locations and treatments. The objectives of the second study were to i.) evaluate the interaction of wheat grazing management and soil and fertilizer N requirements with emphasis on dual purpose wheat, ii.) assess the use of NDVI sensors for N management and forage quantity assessment in wheat grazing systems, and iii.) evaluate forage quality and quantity interactions with N management. Three locations were established and fertilized with N application rates of 0, 34, 67, and 101 kg ha−1 in the fall, followed by simulated grazing. Spring topdress applications were made at rates of 0 and 90 kg ha−1, or a sensor based rate. The impact of grazing on grain production varied by location. NDVI readings correlated with biomass at two of three locations and N recommendations using NDVI sensors resulted in significantly lower N rates and similar yield results to high N application rates. Forage dry matter and N concentration increased with higher N rates.

This book was released on 2015 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain yield and end-use quality are the most important characteristics for hard red winter wheat (Triticum aestivium L.). Improvement of grain quality characteristics of grain from a given growing season and location requires systematic understanding of the genotype chosen, the production environment, and also knowing the consequence of rate and time of individual production packages such as seed treatment, seed rate, nitrogen (N) fertilization, and foliar fungicide applications. The objectives of this study were to: identify the effects of seed rate, genotype, and N top-dressed on yield, agronomic characteristics, and end-use quality of winter wheat; and to determine the effects of seed treatment and flag leaf foliar fungicide application on yield and agronomic characteristics of wheat cultivars. Two experiments were conducted at Havelock, near Lincoln, NE and the High Plains Agricultural Lab (HPAL), near Sidney, NE in 2014 and 2015 using randomized complete block design with split factorial arrangement. Overall foliar N increased grain yield, grain protein concentration, other baking quality indicators such as flour water absorption, peak height, tail area, weakening slope, and depressed grain volume weight, mixing time, and tolerance. Similarly, increased seed rate improved grain yield, seed weight, grain volume weight, flour yield, mixing time, and mixing tolerance. Increased seed rate reduced grain protein, flour water absorption, tail area, peak height, and weakening slope. Seed treated with EverGol Energy and Gaucho showed improved seedling emergence, leaf greenness, grain yield, and seed weight. Application of foliar fungicide at flag leaf stage improved grain yield, seed weight, and leaf area. Among the six genotypes evaluated, ‘Settler CL’ and ‘Freeman’ had the highest overall grain yield. The study demonstrated the importance of seeding rate and the existence of a wider than expected tolerance range for seeding rate. The study also demonstrated the importance of in-season nitrogen top dress and foliar fungicide application to increased winter wheat grain yield and grain quality in Nebraska. However, further research is recommended to fine-tune the factors and interdependence of response in relation to a specific location, season or the prevailing weather condition, and the specific attribute of the genotype seeded.

Em Thell) written by P. Brajcich and published by . This book was released on 1980 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation was motivated by the apparent increase in genetic variability resulting from the systematic combining of gene pools represented by winter and spring types of wheats. It was the objective of this study to provide information regarding the nature of this genetic variability for nine agronomic characters in populations resulting from winter x spring crosses. Evaluations were made for: 1) the amount of total genetic variability; 2) the nature of the gene action making up this genetic variability using parent-progeny regression and combining ability analysis and 3) possible direct and indirect associations for traits which influence grain yield. Experimental populations which involved parents, Fl, F2 and backcross generations were grown at two locations where a spring and a winter environment could be utilized. At the winter site, the research was evaluated over a two year period. When the two experimental sites were compared, greater genetic diversity was observed at the spring site for maturity date, plant height, tillers per plant, kernel weight and grain yield. At the winter site, heading date, grain filling period, harvest index and kernels per spike were found to have more total genetic variation. From the expected mean square values, it would appear that the winter parents contributed more to the total genetic variation for most traits measured at both locations. A large genotype-location interaction was also noted suggesting that estimates of gene action and selection for adapted plant types can be done only at the specific winter or spring site. A large portion of the total genetic variation controlling the traits measured was due to additive gene action. However, at the winter site there was also a large influence of non-additive gene action associated with heading date, plant height, harvest index, tillers per plant, kernel weight, kernels per spike and grain yield. Of special interest was that at the winter site the most promising parental combinations could be predicted based on the general combining ability effects of the individual cultivars for each trait studied. Such data were not available for the spring site. Consistent and high correlations were observed between tillers per plant, kernels per spike and, to a lesser extent, kernel weight and grain yield at the winter location. Some negative associations were observed at the spring location between these traits and grain yield suggesting that yield component compensations were involved in the final expression of grain yield. The other characters measured did not reflect significant correlations with yield. When the correlation values were considered in terms of direct and indirect effects for specific traits, a large direct effect was noted for the three components and grain yield. The other traits exhibited small or no direct effects on grain yield but did have a slight influence on grain yield through tillers per plant, kernels per spike or kernel weight.

Book excerpt: Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.
