Interaction of Sweet Bran inclusion and corn processing method in beef finishing diets.

The study objective was to determine the effects of corn processing method and Sweet Bran (Cargill, Blair, NE) inclusion in beef finishing diets on performance and carcass characteristics. Four hundred and eighty crossbred yearling steers (363 ± 15kg) were assigned to a 2 × 3 factorial arrangement of treatments, consisting of two corn processing methods, steam-flaked corn (SFC) or a high-moisture corn: dry-rolled corn blend (HMC: DRC), and three inclusions of Sweet Bran (0%, 20%, or 40% of diet dry matter). Data were analyzed using the MIXED procedure of SAS as a generalized block design with pen as the experimental unit and block as a fixed effect. Dry matter intake increased linearly as Sweet Bran increased in the diet, regardless of corn processing method (P < 0.01). A corn processing × Sweet Bran interaction (P < 0.01) was observed for feed efficiency (G:F), average daily gain (ADG), and hot carcass weight (HCW). The G:F of steers fed SFC did not change with increasing Sweet Bran concentrations (P = 0.19) and the G:F of SFC-fed steers was 12.4% greater than those fed HMC:DRC without Sweet Bran, but was only 5.3% greater when Sweet Bran was included at 40% (P = 0.04). The ADG of steers increased linearly with increasing concentration of Sweet Bran in both SFC and HMC:DRC-based diets. However, the interaction occurred (P < 0.01) because ADG increased at a greater rate in HMC:DRC-based diets (1.93 to 2.21kg/d for 0% and 40% Sweet Bran, respectively) compared to SFC-based diets (2.18 to 2.27kg/d for 0% and 40% Sweet Bran, respectively;). Accordingly, while the ADG of steers fed SFC was 13% greater than steers fed HMC:DRC without Sweet Bran (P < 0.01), there was no difference in ADG due to corn processing method at 40% Sweet Bran (P = 0.30). In SFC-based diets, HCW tended to increase from 446 to 455kg as Sweet Bran increased (P = 0.06). In HMC: DRC-based diets, HCW linearly increased from 421 to 449kg (P < 0.01), resulting in similar HCW at 40% Sweet Bran (P = 0.28). These data suggest HMC:DRC-based diets are more competitive with SFC-based diets due to similar gains and more similar feed efficiencies when Sweet Bran is fed.

Detection of sweet corn seed viability based on hyperspectral imaging combined with firefly algorithm optimized deep learning.

The identification of sweet corn seed vitality is an essential criterion for selecting high-quality varieties. In this research, a combination of hyperspectral imaging technique and diverse deep learning algorithms has been utilized to identify different vitality grades of sweet corn seeds. First, the hyperspectral data of 496 seeds, including four viability-grade seeds, are extracted and preprocessed. Then, support vector machine (SVM) and extreme learning machine (ELM) are used to construct the classification models. Finally, the one-dimensional convolutional neural networks (1DCNN), one-dimensional long short-term memory (1DLSTM), the CNN combined with the LSTM (CNN-LSTM), and the proposed firefly algorithm (FA) optimized CNN-LSTM (FA-CNN-LSTM) are utilized to distinguish spectral images of sweet corn seeds viability grade. The findings from the experimental analysis indicate that the deep learning models exhibit a significant advantage over traditional machine learning approaches in the discrimination of seed vitality levels, boasting a classification accuracy exceeding 94.26% in test datasets and achieving an accuracy improvement of at least 3% compared to the best-performing machine learning model. Moreover, the performance of the FA-CNN-LSTM model proposed in this study demonstrated a slight superiority over the other three models. Besides, the FA-CNN-LSTM achieved a classification accuracy of 97.23%, representing a significant improvement of 2.97% compared to the lowest-performing CNN and a 1.49% enhancement over the CNN-LSTM. In summary, this study reveals the potential of integrating deep learning with hyperspectral imaging as a promising alternative for discriminating sweet corn seed vitality grade, showcasing its value in agricultural research and cultivar breeding.

Estimation of Crop Water Requirement of Sweet corn crop using CROPWAT 8.0 model

Most of the crops are watered through traditional methods of irrigation, which leads to wastage of water. The Crop Water Requirement (CWR) is necessary to design the irrigation system, which is the total quantity of water required for the crop from sowing to harvest.Optimization of water applied to the crop is essential as the yields of the crop are adversely affected either by excess or deficit water supply. CROPWAT 8.0 requires meteorological data as input such as maximum and minimum temperatures, wind speed, relative humidity, and sunshine hours. The soil and crop data were also given as input for calculating the CWR of sweet corn. The meteorological data of the past ten years was collected from the meteorological observatory, which is located at Agricultural College Farm, Bapatla. The average values of the above-said data were calculated for ten years (2012-2021) to estimate the crop water requirement using CROPWAT 8.0. The crop water requirement was estimated as 332 mm using the CROPWAT 8.0 model. It was found to be minimal in the initial stages (15.60 mm/dec) and found to be maximum in the middle stages (64.80 mm/dec), and again at harvesting stage, it started declining (16.70 mm/dec). CROPWAT 8.0 model gives more accurate amount of water needed for the crop, which in turn helps the crop growers to design the appropriate irrigation scheduling.

The interaction of glycogen nanoparticles with human blood.

Glycogen, a naturally sourced highly branched polysaccharide nanoparticle, has been receiving attention in the field of nanomedicine due to its inherent non-toxicity and biodegradability. However, often in the literature glycogen nanoparticles (NPs) are used that come from different commercial sources (animals and tissues), which have significantly different sizes, molecular weights, and protein content, meaning a comprehensive overview of the interactions of these differently-sourced NPs with the human immune system is missing. Herein, we investigated coagulation, immune cell association and inflammation responses triggered by source-dependent interactions of glycogen NPs in human blood, utilising four types of commercially available glycogen: phytoglycogen (PG) isolated from sweet corn kernels, oyster glycogen (OG), rabbit liver glycogen (RLG), and bovine liver glycogen (BLG). Our results reveal that glycogen NPs exhibit minimal immune cell association, low complement factor, granulocyte, and platelet activation, and have no impact on blood clotting. This is despite the significant physico-chemical differences between the NP types, and when studied at exceptionally high particle concentrations (orders of magnitude higher than other typically studied synthetic systems). Given the similarities in the interactions with blood, either of the commercial glycogens can be leveraged in nanomedicine with respect to immuno-interactions, though PG provides a sustainable and ethically sourced form of NPs from plants. Together, our results highlight a key benefit of using glycogen NPs as injectable biomaterials for therapeutic applications.

PEMANFAATAN KOMPOS DAN MIKORIZA UNTUK MEMPERBAIKI KESUBURAN TANAH, PERTUMBUHAN SERTA PRODUKSI TANAMAN JAGUNG MANIS (Zea mays saccharata)

Inceptisols dominate Indonesia's land area; therefore, future utilization needs to be maximized, especially land that has undergone extensive tillage continuously. Inceptisols have low levels of essential nutrients, especially nitrogen, phosphorus, and potassium. One of the efforts that can be made to improve nutrient content is the application of compost. This study aimed to investigate the effect of compost combined with mycorrhiza on total N, available P, exchangeable K, and soil organic C, as well as the growth and yield of sweet corn. The experimental design used in this study was a completely randomized design consisting of five treatments with three replications. Each observation parameter was analyzed using the F test at the 5% level. Parameters that significantly affected the F test were followed by the DMRT test at the 5% level. All observed data were tested for correlation using SPSS V24 to see the relationship between observation parameters. The results showed that the application of a combination of compost and mycorrhizae increased total N content by 78.7%, available P by 26.6%, soil organic C by 29.54%, plant height by 143.87cm, number of leaves by 11.33 leaves, and cob weight by 294.33 g compared to control. The correlation test showed that applying a combination of compost and mycorrhiza affected N in the soil, so the growth and yield of corn were higher.

Development of heterotic hybrids of sweet corn for green ear yield and other component traits

Forty two experimental hybrids generated through full diallel mating were evaluated in Randomized Block Design during kharif 2019 to study the magnitude of heterosis in sweet corn. Mid-parent heterosis ranged from -21 to 258 for DEW; -25 to 2 for GFW; 3 to 229 for GEY and standard heterosis ranged from 2.13 to 134.95 for DEW; 82.93 to 317.07 for GFW; -15.70 to 68.40 for GEY. Green ear yield exhibited positive significant correlation of mid-parent and commercial heterosis with NKPR, DEW and GFW in common, while no significant association between GEY and TSS was observed. The crosses KH1831 × SC Syn, SC Syn × SC Sel 2 and SC Sel 2 × SC Syn manifested highest mid-parent heterosis for de-husked ear weight, green ear yield and green fodder weight thus utilizing these hybrids in breeding programmes will serve for dual purpose of yield with fodder.

Changes in internal structure and nutritional quality with different types of maize kernels during Grain filling period

To understand the changes in grain internal structure and nutrients during maize filling, Jingkenuo 2000 (waxy corn), Chaosweet 2000 (sweet corn), and Zhengdan 958 (common corn) were used as test materials. This study observed the internal structure of the corn grain and measured the change in nutritional quality during the filling period. Throughout the determination stage, the starch granules did not fill the whole endosperm cell in Chaosweet 2000, and the cell wall was clearly visible. By contrast, the starch granules filled the whole endosperm cell in Jingkenuo 2000 and Zhengdan 958. The protein content in Chaosweet 2000 was significantly (P&lt;0.05) higher than those in Jingkenuo 2000 and Zhengdan 958. With the extension of post-pollination time, the content of soluble sugar decreased significantly (P&lt;0.05) in Chaosweet 2000, Jingkenuo 2000, and Zhengdan 958. Bangladesh J.

Эффективность биопрепаратов при выращивании сахарной кукурузы

In our country, vegetable sweet corn is grown mainly in the Krasnodar and Stavropol territories and the Rostov region; it is also cultivated in the Black Earth Region and in more northern regions, but in smaller volumes. Sweet corn is a relatively young subspecies that arose as a mutant between dentifrice and flint corn. Due to its biochemical characteristics, it is a very susceptible crop and is more damaged by pests and diseases compared to the usual one. A further increase in corn grain production is unthinkable without the widespread and comprehensive use of the latest scientific achievements, where the leading role undoubtedly belongs to new varieties and cultivation technologies. In the climatic conditions of the Rostov region, the biological characteristics of 4 hybrids of vegetable corn were studied: Early Golden F1, Sweet Nugget F1, Caramello F1 and Noa F1 and resource-saving technologies with the basics of biologization and greening of agriculture. Research has established that, on average, over the years of research, a high yield of cobs was obtained by the hybrids Caramello F1 - 14.42 t/ha and Noa F1 - 15.53 t/ha. Treatment of vegetative vegetable corn plants with biological preparations Albit and Rauactiv provided a significant increase in the yield of all studied hybrids.
