In the frame of alternative protein sources, chickpea (<i>Cicer arietinum</i>) emerged as a rich source of dietary proteins besides containing good amount of carbohydrate, fat, and fiber. As a protein ingredient, chickpea is available in three forms, namely, flour, concentrate, and isolate. This chickpea protein can be extracted using both wet and dry fractionation methods where the former one includes wet extraction followed by isoelectric precipitation, while the later one indicates dry milling followed by air classification. However, different nonthermal emerging technologies have been seen to assist in extracting protein as well as modifying their functionalities. This review gives an outline of the recently available literature on composition, industrial processing and associated technological challenges, functionality, and application of chickpea protein ingredients. Furthermore, discussion on the modification/improvement of chickpea protein functionality with the assistance of emerging technologies and the potentiality of by-products produced during chickpea protein processing are also included. Based on the available findings and discussion, it is seen that apart from being a comparable source of alternative animal-based protein to extract, chickpea derived by-products can also be a potential source of valued ingredients that might contribute to the circular economy.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"5 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142246268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pumpkin and squash have versatile uses but are most popular in culinary, ornamental, snacking, and seed oil industries. The production of <i>Cucurbita</i> crops is hindered by diseases caused by fungal, oomycetes, and viral pathogens. Host resistance is an important component of integrated disease management for <i>Cucurbita</i> crops and is a major goal for plant breeders. This review addresses the major diseases of <i>Cucurbita</i>, including powdery mildew, downy mildew, <i>Phytophthora</i> rot, and aphid and whitefly transmitted viruses, with an emphasis on germplasm exploitation for the development of resistant cultivars. Resistance to powdery mildew derived from <i>Cucurbita okeechobeensis</i> subsp. martinezii (designated <i>PM-0)</i> has been extensively deployed in commercial cultivars and was recently mapped on chromosomes 3 and 10 of <i>Cucurbita moschata</i> and <i>Cucurbita pepo</i>, respectively. Resistance to <i>Phytophthora</i> crown rot is present across several <i>Cucurbita</i> species, including <i>Cucurbita lundelliana</i>, <i>C. okeechobeenesis</i> subsp. <i>okeechobeenesis</i>, <i>C. moschata</i>, and <i>C. pepo</i>. Mapping studies have identified significant loci associated with <i>Phytophthora</i> crown rot resistance on chromosomes 4, 11, and 20 of <i>C. moschata</i> and chromosomes 4, 5, 8, 12, 13, 16, and 19 of <i>C. pepo</i>. Sources of resistance to aphid-transmitted viruses exist in <i>C. moschata</i>, <i>Cucurbita ficifolia</i>, <i>Cucurbita ecuadorensis</i>, <i>Cucurbita martinezii</i>, <i>C. ecuadorensi</i>s, <i>Cucurbita maxima</i>, and <i>Cucurbita foetidissima</i>. The availability of DNA markers linked to resistance against zucchini yellow mosaic virus and papaya ringspot virus in <i>C. moschata</i> and <i>C. pepo</i> has facilitated marker-assisted selection (MAS) in breeding programs. On the other hand, sources of resistance to tomato leaf curl New Delhi virus (ToLCNDV), a major whitefly-transmitted virus in <i>Cucurbita</i>, have been identified in <i>C. moschata</i>, <i>C. lundelliana</i>, and <i>C. okeechobeensis</i>. A major locus conferring resistance to ToLCNDV in <i>C. moschata</i> was recently mapped on chromosome 8 enabling the application of MAS with a prediction accuracy of 94.3%.

Little is known of the relative N efficiencies resulting from potential inter-stature differences in dry matter formation and N processes during pre- and post-silking stages. To investigate this, two field rainfed experiments were conducted in West Lafayette, IN. The experiments included factorial combinations of two tall- and two short-statured maize hybrids subjected to three N rates: 0 (unfertilized), 168 (moderate), and 224 kg N ha<sup>−1</sup> (elevated) applied at planting. Short hybrids with a 25% reduced stature showed no statistically significant differences in seasonal biomass accumulation and N uptake, or in biomass partitioning to grain (harvest index) versus stover at maturity relative to conventional tall hybrids. Increased leaf biomass and ear growth at silking, plus comparable quantities of N remobilization from stems during grain filling, with short-stature maize contributed to its grain yield parity with tall-stature maize. Additionally, our research revealed other noteworthy findings: short-statured maize had higher N harvest index and N recovery efficiency than the tall maize, implying more N status resiliency at moderate N rates. The lack of interactions between N × stature in most studied traits suggests that short hybrids can perform at least as well as conventional tall hybrids across a range of N rates.

In this study, we identified and compared endophytic diazotrophic communities and their associated soil counterparts using amplicon sequencing of the nitrogenase iron protein (nifH) of 36 surfaced sterilized CitraBlue St. Augustinegrass cultivar [<i>Stenotaphrum secundatum</i> (Walter) Kuntze] sprigs and 12 aggregated soil samples.

Both mowing height (<i>p</i> < 0.001) and N fertilization rate (<i>p</i> < 0.05) had a significant effect on the diversity of endophytic diazotrophs.

This study aims to (i) assess the effects of equidistant versus non-equidistant plant arrangements on soybean yield and seed quality across different regions in the United States; (ii) explore the effect of modified soybean plant canopy resulting from different plant arrangements on yield and seed quality. In 2021 and 2022, 13 trials were conducted in Kansas, Mississippi, and South Dakota. The treatments consisted of three equidistant plant arrangements of 13 cm × 13 cm, 15 cm × 15 cm, and 20 cm × 20 cm (620,000, 430,000, 242,363 seeds ha<sup>−1</sup>, respectively), and a non-equidistant with 38 cm of row space (321,236 seeds ha<sup>−1</sup>). Soybean yield and yield components were collected, and canopy coverage (%) was monitored throughout the growing season. Overall, there is no evidence of any advantage of equidistant over non-equidistant arrangements in soybeans. Yield differences related to spatial arrangement were observed in only three trials: the non-equidistant increased yield compared to the 20 cm × 20 cm equidistant arrangement (lowest density) in two trials, while the 13 × 13 and 15 × 15 patterns (highest density) showed higher yield compared to the 20 cm × 20 cm arrangement in one trial.

Azoxystrobin, an acropetal penetrant quinone outside inhibitor fungicide, is commonly applied in turfgrass and other agricultural settings, protecting desired plants from fungal pathogens by inhibiting fungal growth. Field research was initiated in Raleigh, NC, and repeated in time to assess the effect of post-application mowing timing and clipping collection practices on azoxystrobin residue persistence in tall fescue (<i>Schedonorus arundinaceus</i> Schreb.). At trial initiation, azoxystrobin was applied at the maximum single application rate (0.61 kg ai ha<sup>−1</sup>) to tall fescue plots. To determine the effect of initial mowing timing, plots were mowed (9.5 cm) at 0, 1, 2, 3, 7, or 14 days after application (DAA). To determine the effect of clipping removal, plots were mowed at 3, 10, and 17 DAA and clippings were either returned to the canopy or bagged and removed. Concurrently, soil cores (92 cm<sup>2</sup>) were collected at 3, 7, 14, and 21 DAA and then segmented into remaining aboveground vegetation and soil (0.0- to 2.5-cm depth) for residue analyses. Mowing timing affected azoxystrobin residue in the vegetation and in soil. When clippings were returned to the canopy, 5% more azoxystrobin was detected in the vegetation at 7 and 14 DAA. At 3 and 7 DAA, in the soil, returning clippings resulted in >3% more of the applied azoxystrobin compared to removing clippings. Data from this research may allow for extended fungicide intervals for brown patch suppression and demonstrate the importance of returning clipping to turf systems to retain azoxystrobin residues.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142237025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research demonstrates that a single autumn ethephon application can suppress zoysiagrass seedhead production the following spring, but the optimum application timing is not well‐defined. The objective of this research was to determine the optimum window for an effective ethephon application for ‘Meyer’ zoysiagrass seedhead suppression. Small‐plot field research was conducted in Indiana, Kansas, Arkansas, and Tennessee. Seedheads were suppressed up to 99% depending on application timing. In Indiana, applications made on September 19 provided 99% seedhead suppression. In Kansas, applications between August 30 and September 18 yielded >64% seedhead suppression. In Arkansas, applications between October 3 and October 17 yielded >52% seedhead suppression. In Tennessee, applications between September 19 and October 23 provided >78% seedhead suppression. Applications made outside these windows resulted in more seedhead production at each respective location. Interestingly, optimum application timing was approximately 2 weeks later in Arkansas and Tennessee compared to Indiana and Kansas. Using growing degree days, a nonlinear Gaussian model was fit to predict the optimum ethephon application timing. In addition to data from this research, the proposed model accurately predicted observed zoysiagrass seedhead suppression in previously published research.

Using five decades of data compiled by Texas A&M AgriLife Research, trends in grain sorghum were retrospectively assessed. Performance data from over 4094 hybrids were collected between 1970 and 2021 in a total of 514 county-year environments. Hybrids in these trials were either commercially available or in the final stages of testing for release. A linear mixed model approach produced the best linear unbiased predictions of genotypic and environmental effects for grain yield and relevant agronomic traits. These measures, as well as the raw data, were used to inform and visualize trait dependencies, yield gains, and geographic regions with similar effects on hybrid performance. Over these decades, grain yield increased at an average rate of 0.03 t ha<sup>−1</sup> per year. A strong positive relationship between hybrid yield and plant height, as well as several other correlations, were detected through separate periods of yield increases which occurred in the early 1980s and 1990s; since that time, a sinusoidal pattern of yield performance has prevailed.
