In India, spent buffaloes are the main contributors of meat, which is tough and low priced and poor demand in the market. In this context, a new technological intervention is needed for restructuring of meat to enhance value-added meat production. Accordingly, an investigation was carried out to analyze the efficacy of different levels of flaxseed flour (C, T1, T2, and T3) as a novel binder for making of Restructured Buffalo Meat Slices (RBMS). The results revealed that T3 (RBMS added with 6% flaxseed flour) demonstrated significantly (P<0.01) higher cooking yield, water-holding capacity (WHC), batter stability and lower diameter shrinkage than control and RBMS incorporated with 2 % and 4 % flax seed flour. None of the treatments had significant influence on pH, total protein extractability, collagen content and solubility of RBMS. Moreover, T3 revealed significantly (P<0.01) higher moisture, total protein, total fat and total ash content than RBMS formulated with other levels of flax seed flour. Conversely, significantly lower in hardness, springiness, chewiness and higher in cohesiveness than other treatments. However, T3 influenced the colour scores, though at different degrees. Ultra structural images of cooked samples displayed the protein matrix between myofibrils which indicates gel network of flaxseed gum and proteins, subsequently caused more cohesiveness. This implies that the flaxseed flour acted as excellent novel binder for binding meat pieces. T3 has proven significantly greater sensory scores than other treatments. Thus, it is clearly evident that T3 has improved most of the quality attributes of buffalo meat and can be recommended as a novel value added technology for meat industry.

Aim/background: Lomariopsis guineensis (Underw.) Alston is an epiphytic climbing fern. It is widely distributed in Africa where it is also used in traditional medicine and as food. There are no previous reports of any constituents of the plant, hence this study to isolate any phytoconstituents. Method: The ethyl acetate extract of the leaves was subjected to column chromatography and isolated constituents were characterized using nuclear magnetic resonance and mass spectrometry. Results: Three compounds were isolated and identified as cycloartenol, pheophytin A and a new isoflavone (5, 7-dihydroxy-4′ methoxy-6,8-dimethylisoflavone). Conclusion: Three phytochemicals including a new isoflavone are reported from the plant for the first time.

The effect of three fungicide treatment programmes and the level of spring nitrogen fertilisation on the seed yield of two types ofcultivars of Brassica napus L. sown at two different seeding rates was studied in a field experiment. The subject of the study was anopen-pollinated cultivar ‘Casoar’ and a restored hybrid cultivar ‘Visby’. Three plant protection programmes, two levels of spring nitrogenfertilisation (160 and 220 kg N⋅ha1), and two different seeding rates for each cultivar (‘Visby’—50 and 70 seeds⋅⋅m2; ‘Casoar’—60 and 80 seeds⋅m2) were included. The most intensive protection programme comprised three fungicide treatments: first in autumn at the six-leaves-unfolded stage—BBCH 16, second in spring at the stem elongation stage—BBCH 33, and third at the full flowering stage—BBCH 65. One of two less intensive programmes of plant protection included fungicide application in autumn at the sixleaves-unfolded stage—BBCH 16 and at the full flowering stage—BBCH 65, while the second included fungicide application in spring at the stem elongation stage—BBCH 33 and at the full flowering stage—BBCH 65. The effectiveness of the protection programmes and nitrogen fertilisation was influenced by the intensity of abiotic stress factors. The average yield from the plots protected against pathogens was significantly higher than that from the untreated plots. The increase of nitrogen fertilisation from 160 to 220 kg⋅ha1 also caused a significant increase of average seed yield. The yield of cultivar ‘Visby’ was higher and less dependent on the seeding rate compared to cultivar ‘Casoar’.Keywords: Winter oilseed rape; Cultivars; Disease control; Nitrogen fertilisation; Seeding rate; Sclerotinia sclerotiorum; Leptosphaeria spp.; Alternaria spp. Botrytis cinerea.
通过田间试验，研究了三种杀菌剂处理方案和春季氮肥水平对两种不同播种率下甘蓝型油菜两个变种种子产量的影响。这项研究的对象是一个授粉的按蚊品种“Casoar”和一个恢复的杂交品种“Visby”。包括三个植物保护计划，两个春季氮肥水平（160和220 kg N·ha1），以及每个品种的两种不同播种率（“Visby”——50和70种子·m2；“Casoar”——60和80种子·m2）。最密集的保护方案包括三种杀菌剂处理：第一种是在秋季六叶展开期BBCH 16，第二种是在春季茎伸长期BBCH 33，第三种是在全花期BBCH 65。两个强度较小的植物保护方案之一包括在秋季六叶展开期施用杀菌剂（BBCH 16）和在盛花期施用杀菌素（BBCH 65），而第二个方案包括在春季茎伸长期施用杀菌药（BBCH 33）和在全花期施用杀真菌剂（BBCH65）。保护方案和氮肥施用的有效性受到非生物胁迫因素强度的影响。受病原体保护的地块的平均产量显著高于未经处理的地块。施氮量从160公斤增加到220公斤，也显著提高了平均种子产量。与品种“Casoar”相比，品种“Visby”的产量更高，对播种率的依赖性更小。关键词：冬油菜；栽培品种；疾病控制；氮肥；播种率；核盘菌；纤球菌属。；链格孢。灰葡萄孢。

To study the feasibility of CROPGRO_cotton model in the optimization of cotton irrigation management under different climatic conditions, the empirical values corresponding to 25%, 50% and 75% of the empirical frequencies of precipitation were obtained by ranking the frequency fitness line of precipitation data during 20 years of cotton fertility at the experimental site, and then the years corresponding to three empirical frequencies were selected as typical years: 2015 (abundant water year), 2001 (flat water year), and 2006 (dry water year). By combining cotton fertility stages, irrigation frequency and irrigation amount, 21 irrigation regimes (T1~T21) were identified and simulated using the calibrated DSSAT model for cotton irrigation regimes under the three precipitation year types, and the results showed that under the best combination of irrigation usage, yield and water utilization, 2015 (abundant water year), 2001 (flat water year), and T20 irrigation management should be selected in 2006 (dry water year).Under the three typical years, the effect of temperature change on cotton yield and water utilization was investigated, and it was found that the increase of temperature would reduce cotton yield and water utilization, but a reasonable irrigation management would reduce the negative effect of climate change on cotton yield and water utilization,According to the simulation results under different situations, T20 irrigation management can minimize the yield variation range under temperature change, and has a high water utilization rate, which has good applicability.

As the population increases, more people need to be fed. In order to find a physical method that influence the corn production, this work is dedicated to evaluating the impact of pre-sowing red laser irradiation of corn (Zea mays L.) seeds on harvest yield. The aim was to analyze the influence of red laser radiation on corn seeds, on the quantity and quality of yield, on large-scale and open field production. It is hypothesized that at least one red laser irradiation treatment could improve corn crop yield. In radiation, a red laser diode at 660 nm with a power of 100 mW was used, two radiation densities were used (D1: 2 mW cm-2 and D2: 4 mW cm-2), applied during 4 exposure times (T1: 15, T2: 30, T3: 60 and T4: 120 s) and a control group without treatment (C). A random arrangement was used, in a 2 x 4 factorial scheme, totaling 8 treatments and control, with four replications. The data were subjected to an ANOVA and the means were compared with the Tukey test (HSD; p ≤ 0.05). The D2-T4 treatment produced the most significant impact concerning the control, improving yield by 19±1% (3 t ha-1), cob length 18±1%, cob diameter 22±3%, weight (16±2%) and corn kernels size (14±2%). We also find negative effects on yield, D2-T1 decreased crop yield around 16±1% (2.24 t ha-1). The results show a way to include this technique as a technique that can to increase or decrease corn yield. Keywords: Cob length; Maize; open field; Thousand kernel weight.

Field experiments were conducted during Rabi 2018-19 (September to January) and Kharif 2019 (May to September). Medium duration rice cv. CO(R) 51 was used as a test variety at Tamil Nadu Agricultural University, Coimbatore, India to study the effect of Triafamone on broad spectrum weed control in transplanted rice. Triafamone was applied at two times. First set of treatments (30, 40,50 and 100 g/ha) applied two to three leaf stage of weeds and second set treatments imposed (30, 40,50 and 100 g/ha) at three days after transplanting of the rice crop. These treatments were compared with Pyrazosulfuron ethy 10% WP @ 15 g/ha, Pretilachlor 5% EC @ 750 g/ha, hand weeding @ 20 and 40 days after transplanting and unweeded control. The major grasses were Echinochloa crus-galli (L.) and E. colonum (L.) while the sedge weed included Cyperus nutans (L.). Among the broad leaved weeds Eclipta alba (L.) and Bergia ammanioides were the dominant species. In both the seasons of the study, lesser population of grass was recorded with the pre and early post emergence application of triafamone herbicide 40 g a.i. ha-1 (1.41 and 1.41 per m-2 at 28 and 42 DAA for both the seasons respectively) and it was closely followed by application of triafamone herbicide 50 g a.i. ha-1 and application of PE Pretilachlor at 0.75 kg a.i. ha-1 and EPOE Pyrazosulfuron ethyl at 15 g a.i. ha-1. The same trend was observed for broad leaved weeds and their weed dry weights. Application of triafamone herbicide at 40 g a.i. ha-1 as pre emergence and early post emergence application recorded highest weed control efficiency of 100, 97.7 and 99.6 % and 97.8% at 42 DAA during both years of experimentation and also resulted in higher grain yield (8052 and 8182 kg ha-1 during rabi 2018-19 and 9018, 9175 kg ha-1 during Kharif 2019). Further, it is noticed that, there was no residual toxicity of herbicide to the succeeding crops. Hence, application of Triafamone 40 g a.i. ha-1 either pre or early post emergence herbicide has higher productivity and no residues in transplanted rice ecosystem. Key words: Triafamone, efficacy, weeds and transplanted rice ecosystem
野外实验在2018-19年拉比（9月至1月）和2019年哈里夫（5月至9月）期间进行。以印度哥印拜陀泰米尔纳德邦农业大学的中效水稻品种CO（R）51为试验品种，研究了三唑酮对移植水稻广谱除草的影响。Triafamone分两次使用。第一组处理（30、40、50和100克/公顷）施用二至三叶杂草期，第二组处理在水稻作物移植后三天施用（30、40,50和100克每公顷）。将这些处理与吡嘧磺隆乙醇10%可湿性粉剂15g/ha、预甲草胺5%EC 750g/ha、人工除草20d和40d以及未播种对照进行比较。主要杂草为鹅掌楸（Echinochloa crus galli，L.）和大肠杆菌（E.colonum，L.），莎草为莎草（Cyperus nutans，L.）。在研究的两个季节中，在羽化前和羽化后早期施用40 g a.i.ha-1（两个季节在28和42 DAA时分别为1.41和1.41/m-2），草的数量较少，紧随其后的是施用50 g a.i.ha-1和0.75 kg a.i.ha-1的PE预甲草胺和15 g a.i.a-1的EPOE吡嘧磺隆乙基。对于阔叶杂草及其杂草干重也观察到了相同的趋势。在两年的试验中，以40g a.i.ha-1作为出苗前和出苗后早期施用三唑酮除草剂，在42DAA时的杂草控制效率分别为100%、97.7%、99.6%和97.8%，还带来了更高的粮食产量（2018-19年拉比期间为8052和8182 kg ha-1，2019年哈里夫期间为90189175 kg ha-1）。此外，值得注意的是，除草剂对后续作物没有残留毒性。因此，在出苗前或出苗后早期施用Triafamone 40g a.i.ha-1除草剂具有较高的生产力，并且在移植水稻生态系统中没有残留。关键词：三唑酮、药效、杂草与水稻移植生态系统

Medium duration rice cv. CO(R) 51 was used as a test variety at Tamil Nadu Agricultural University, Coimbatore, India to study the effect of Triafamone on broad spectrum weed control in transplanted rice. Triafamone was applied at two times. First set of treatments (30, 40,50 and 100 g/ha) applied two to three leaf stage of weeds and second set treatments imposed (30, 40,50 and 100 g/ha) at three days after transplanting of the rice crop. These treatments were compared with Pyrazosulfuron ethy 10% WP @ 15 g/ha, Pretilachlor 5% EC @ 750 g/ha, hand weeding @ 20 and 40 days after transplanting and unweeded control. The major grasses were Echinochloa crus-galli (L.) and E. colonum (L.) while the sedge weed included Cyperus nutans (L.). Among the broad leaved weeds Eclipta alba (L.) and Bergia ammanioides were the dominant species. In both the seasons of the study, lesser population of grass was recorded with the pre and early post emergence application of triafamone herbicide 40 g a.i. ha-1 (1.41 and 1.41 per m-2 at 28 and 42 DAA for both the seasons respectively) and it was closely followed by application of triafamone herbicide 50 g a.i. ha-1 and application of PE Pretilachlor at 0.75 kg a.i. ha-1 and EPOE Pyrazosulfuron ethyl at 15 g a.i. ha-1. The same trend was observed for broad leaved weeds and their weed dry weights. Application of triafamone herbicide at 40 g a.i. ha-1 as pre emergence and early post emergence application recorded highest weed control efficiency of 100, 97.7 and 99.6 % and 97.8% at 42 DAA during both years of experimentation and also resulted in higher grain yield (8052 and 8182 kg ha-1 during rabi 2018-19 and 9018, 9175 kg ha-1 during Kharif 2019). Further, it is noticed that, there was no residual toxicity of herbicide to the succeeding crops. Hence, application of Triafamone 40 g a.i. ha-1 either pre or early post emergence herbicide has higher productivity and no residues in transplanted rice ecosystem. \u0000Key words: Triafamone, efficacy, weeds and transplanted rice ecosystem","PeriodicalId":11648,"journal":{"name":"Emirates Journal of Food and Agriculture","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49102863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, it was performed identification and quantification of flavonoids (apigenin, chrysin, hesperetin, kaempferol, luteolin, naringenin, and quercetin) and flavonoid glycosides (rutin and vitexin) in total 49 samples of five different honey types from Bosnia and Herzegovina: meadow honey (MH, 22 samples), forest (FH, 10), acacia (AH, 7), chestnut (CH, 5), and heather honey (HH, 5). Additionally, evaluation of correlations between FC and total hydrophilic antioxidant score (antioxidant activity against both: ROO· + OH·) in supernatants (s) and in bulk (noncentrifuged) solution (b) of these honey types was performed. Moreover, correlations between flavonoids content (FC) and previously reported antioxidant activity against both peroxyl and hydroxyl free radicals (AC(ROO·) and AC(OH·)) for the same honey samples was examined. High performance liquid chromatography with photodiode array detector (HPLC-DAD) and isocratic elution mode was used as method of analysis. Flavonoids were extracted by solid phase extraction (SPE). The average contents of three flavonoids (chrysin, naringenin, and luteolin) in MH were statistically higher than in AH (p**<0.01). Also, the average content of naringenin in FH was statistically higher than in CH (p*<0.05). We observed a high (positive) linear correlation between FC and AC(ROO·) in s of four honey types (FH, AH, HH, CH) (R2=0.920). If we correlate FC and AC(ROO·)s of three honey types (FH, AH, HH), linearity is very high (R2=0.968), and for FH, AH, CH linearity is complete. The correlation between FC and AC(ROO·) in b of the same honey types is similar, but lower. The correlation does not exist between FC and AC(OH·) neither in s nor in b of five or four honey types, but for FC to both (AC(OH·)s and AC(OH·)b) of three honey types (FH, AH, CH), linearity is moderate (R2=0.732 and R2=0.696, respectively). Keywords: antioxidant activity, correlations, flavonoids, honey, HPLC-DAD.

This study was conducted to investigate possible use of juice-extracted sweet sorghum stalks (bagasse) as a quality roughage source through silage making. A total of 21 different sweet sorghum (Sorghum bicolor var. saccharatum (L.) Mohlenbr.) genotypes supplied from different sources were used as the primary material of the study. Field experiments were conducted in a randomized blocks design with 4 replications on the experimental fields of Eastern Mediterranean Agricultural Research Institute under 2nd crop conditions during the growing seasons of 2016 and 2017 years. Plants were harvested for bioethanol production at milk-dough stage of panicle grains. Plant leaves and panicles were stripped and remaining stalks were extracted through squeezing. Juice-extracted stalks (bagasse) were ensilaged for 60 days and quality traits were analyzed at the end of silage period. As the average of two years, bagasse yields varied between 42.6-113.9 t ha-1, silage DM yields varied between 11.6-40.0 t ha-1. In addition, crude protein (CP) content, acid detergent lignin (ADL), neutral detergent fiber (NDF) and acid detergent fiber (ADF) values varied between 29.79 - 50.84 g/kg DM, between 49.3 - 91.4 g/kg DM, between 525.1-694.8 g/kg DM and between 351.2-486.8 g/kg DM, respectively. It was concluded based on present findings that silages made from juice-extracted stalks of sweet sorghum grown under 2nd crop conditions of Cukurova region could be used as quality roughage source for livestock.

Cancer is one of the leading causes of death in our age. In addition to the treatments used in cancer, plants are frequently used in complementary or alternative approaches. Plants of the genus Satureja are used world wide for various purposes, primarily as complementary therapies. For this purpose, in this study, the antioxidant potential and phenolic content of the Satureja cuneifolia plant, which is frequently consumed as a spice and tea among the public, and its cytotoxic and apoptosis-inducing effects on cancer cells were tried to be revealed. The cytotoxic effect of the extracts prepared with three different solvents (methanol, ethanol and water) was determined by the MTT test in colorectal cancer (DLD1) and promyelocytic leukaemia cell lines (HL60). Then the expression levels of five apoptotic gene regions (apaf-1, bax, bcl2, card4, casp3 and tp53) were evaluated with Real-Time PCR. The antioxidant potential was determined via the DPPH test, and HPLC was used to screen for phenolic substances. As a result, it was determined that the extracts have cytotoxic effects and have a variable but positive effect on pro-apoptotic gene expressions. When the antioxidant potential was evaluated, it was determined that the methanolic extract had a more radical scavenging effect (IC50: 105.02±0.034 µg/ml). In conclusion, the cytotoxic and apoptosis-inducing potentials of the extracts obtained from the S. cuneifolia plant were revealed for the first time upon DLD1 and HL60 cell lines in this study. This study is a pioneer for future studies in cancer therapy. Keywords: Apoptosis; qRT-PCR; Spice; Turkey; Wild savory
