Sustainable certificates are developing in the palm oil industry along with the issue of sustainable development in agriculture. Farmers, as the main palm oil producers, are advised to adopt sustainable certificates. Therefore, this study aimed to investigate the determinants of the intention to adopt palm oil sustainable certification in West Borneo farmers. The theory of planned behavior was applied, namely the attitude toward behavior, subjective norm, and perceived behavioral control, with environmental concern as an extended variable. One hundred seventy independent farmers from several regencies in the West Borneo Region were analyzed using structural equation modeling and partial least squares. The results showed that the attitude toward behavior, subjective norm, and perceived behavioral control had a significant effect on the intention to adopt the sustainable certification. However, environmental concern only influenced attitude toward behavior, with no significant effect on subjective norm and perceived behavioral control. This study implies that factors other than environmental concern significantly affect the intention to adopt sustainable certification in palm oil smallholders.

Bitter melon is a medicinal plant with wide-ranging health benefits. Being complex in chemical constituents, poor evidence is available to establish the exact therapeutic benefits of different phytochemicals present in bitter melon. In the present study, bitter melon fruit skin, flesh, seeds and whole fruit were assessed to estimate alkaloid and saponin contents and subsequently bio-evaluation was performed to ascertain their potential as more potent hyperglycemic and hyperlipidemic moderators for the first time. For the feeding trial, Sprague-Dawley rats were used. Bitter melon seeds have a high amount of total alkaloids, while the flesh part has maximum total saponin contents. The group of rats fed with a diet containing seeds powder showed a more prominent impact in lowering blood glucose levels and increasing serum insulin concentration in hyperglycemic and hyperlipidemic rats. The flesh part with maximum saponin contents exhibited a substantial impact in lowering cholesterol, LDL and triglycerides and increasing HDL levels. The antihyperglycemic and antihyperlipidemic activities have a direct association with the presence of these chemical constituents. Alkaloids were found to be more potent antihyperglycemic while saponins were found to be antihyperlipidemic moderators.

Pesticides are considered a risk to pollinators; however, little is known about the possible effects of their injudicious use on pollinators, including the ecosystem services provided to crops and wildflowers. Recently, great attention has been paid to the effects of neonicotinoids pesticides on pollinators and their potential role in harming the health of bees all over the world. Sunflowers, being self-incompatible plants, rely on insects, primarily bees, for effective cross-pollination and successful seed-set. Ensuring the presence of sufficient pollinators in the field is crucial for facilitating pollen movement between flowers and promoting optimal seed development. However, the reliance on insect-mediated cross-pollination also makes sunflowers susceptible to pest attacks, which can negatively impact seed production. To mitigate these potential threats and achieve increased seed yields, careful consideration is given to the judicious use of pesticides. Striking the right balance between providing adequate pollinators and implementing appropriate pest management strategies is vital for maximizing sunflower crop productivity. To reveal such potential impacts of neonicotinoid insecticides, we undergo the current study that aimed to estimate flower visitation and pollination in a sunflower crop by applying three neonicotinoid insecticides i.e. imidacloprid, clothianidin, and thiamethoxam, including the control group for two years i.e. 2020, and 2021. In all experimental plots, we quantified floral visitors for fourteen days at three different times (8 am, 12 pm, and 5 pm). Floral visitors were divided into three groups, Apis bees, Non-Apis bees, and butterflies. After the maturation period, the achenes from each capitulum were separated and brought for weight. We discovered that this study confirmed the adverse effect of neonicotinoids pesticides on sunflower production.

Eight genotypes of oat (Avena sativa L.) were evaluated across four locations with two standard checks under rainfall conditions from 2017 to 2018. Both agronomic and chemical composition data were collected. The analysis of the results indicated a statistical significance difference (P < 0.01) in the days of 50% flowering stage, plant height, biomass yield, leaf-to-stem ratio, dry matter yield, date of maturity, and seed yield. For the collecting parameters, the overall mean was measured from days of 50% flowering stage taking (54.83–86.58) days, plant height (86.04 to 108.56 cm), biomass yield (36.19 to 47.47 t/ha), leaf-to-stem ratio (0.25 to 1.32), dry matter yield (6.96 to 9.79 t/ha) the maturity date (119.0 to 130.98 days) and seed yield (33.38 to 43.49 qu/ha). There were no statistically significant differences (P > 0.05) in ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), and in-vitro dry matter digestibility (IVDMD) among genotypes. The additive main effects and multiplicative interaction (AMMI) analysis for dry matter yield and biomass yield were influenced by environment and genotype. Among the study locations, Tulo was more of an ideal environment for oat crops followed by Chiro. Among the eight oat genotypes evaluated in this trial, the genotypes ILRI#5450 and ILRI#5442 revealed higher agronomic performance than the standard check and remaining studied genotypes. Therefore, oat genotypes ILRI#5450 and ILRI#5442 should be recommended for wider cultivation and need further breeding improvement investigation as animal feed in Eastern Oromia and similar agro-ecology to Ethiopia.

Agricultural fields prone to waterlogging condition induce physiological stress on fruit trees as it affects root respiration and nutrient uptake. However, the information on the growth performance of avocado under waterlogging condition is limited, particularly in terms of morphological and physiological performances. Therefore, this study was designed to evaluate the performance of avocado rootstocks under different waterlogging levels under shade condition. The experiment was conducted using a complete randomized design with factorial arrangement using Ettinger variety as scion that was grafted on Guatemalan and Mexican rootstock races at three waterlogging levels (50%, 75% and 100%) in three replications. The result showed that morphological growth of avocado grafted on Guatemalan race outscored in number of buds, shoot growth, rootstock elongation and scion shoot tip growth compared to the one grafted on Mexican race. Similarly, photosynthesis, transpiration and stomata conductance were significantly affected by the races, waterlogging levels and interaction of the two main factors. The result indicated that the Guatemalan race significantly improved photosynthesis, transpiration, stomata conductance and water use efficiency nearly by 50% in all waterlogging levels as compared to the one grafted on Mexican race. However, the smallest transpiration and water use efficiency were recorded at 100% waterlogging level from the Mexican race. Generally, the study revealed that Guatemalan race used as rootstock gave a strong morpho-physiological performance as compared to the Mexican race. Similarly, waterlogging level at 75% induced strong morphological and physiological performances in Guatemalan race compared to the seedling subjected to 50% and 100% waterlogging. Thus, the finding revealed that the Guatemalan race can be a potential rootstock under waterlogging/saturated soil condition in loamy sand soil texture.

In this study, purified thermo- and acid-stable cellulase from the Bacillus licheniformis was used for improving physical and sensory properties of wheat bread. The thermostable cellulase was harvested, purified and characterized from isolated B. licheniformis species. The impact of parameters such as temperature, pH, and metal ions was tested on the purified cellulase enzyme. The purified enzyme was found to be stable at pH 4.0 and also thermally stable for 6 hat 45°C. Purified cellulase was used in preparation of wheat dough followed by the preparation of baked final product wheat bread. The final baked product showed a significant decrease in hardness, adhesiveness and also chewiness. The moisture-holding capacity was significantly increased compared to control. Furthermore, the effect of cellulase in combination with amylase was also studied in preparation of bread. The improvement in sensory parameters such as volume, color, texture, aroma and taste was observed on treating the dough with a combination of cellulase and amylase.

The study aimed to determine the effects of cane storage periods on pre-harvested burnt and unburnt green harvested canes on quality characteristics and sugar yield of sugarcane varieties at Finchaa Sugar Factory, Ethiopia. Experiments were conducted on a split–split plot design with two varieties, N 14 and N Co 334 as main plots, types of canes burnt and unburnt green harvested canes as sub-plots, and eight cane storage periods (0, 24, 48, 72, 96, 120, 144, and 168 h) as sub–subplots with three replications. All quality parameters were investigated using the standard procedure. The results showed that the loss in cane weight increased and pol %, purity % juice, estimated recoverable sugar, and sugar yield decreased significantly with increasing periods of storage. The results also indicated that losses were more in burnt harvested canes than the unburnt canes over the storage period. Brix and reducing sugar in juice increased with the storage periods and these were more in burnt canes than unburnt harvested canes. The loss in cane weight, pol, juice purity, recoverable sugar, and sugar yield was high in NCo334 variety at each storage period. The pol and purity % juice, recoverable sugar % cane, and sugar yield were more in burnt and unburnt harvested canes in both varieties at storage periods. The findings suggested that the N 14 cane variety of burnt harvested canes and green canes should be crushed within 24 and 48 h to obtain better sugar quality than N Co 334 variety.
本研究旨在确定在埃塞俄比亚Finchaa糖厂，采收前烧焦和未烧焦的青采甘蔗的贮藏期对甘蔗品种品质特性和糖产量的影响。以N - 14和N - Co - 334两个品种为主要样地，以燃烧和未燃烧的青采甘蔗类型为次样地，8个贮藏期(0、24、48、72、96、120、144和168 h)为次样地，3个重复。采用标准程序对所有质量参数进行了研究。结果表明，随着贮藏时间的延长，甘蔗重量损失增加，果汁纯度、估计可采糖和糖产量显著下降。结果还表明，在贮藏期间，燃烧的收获的甘蔗比未燃烧的收获的甘蔗损失更大。随着贮藏时间的延长，果汁中的糖度和还原糖增加，并且在已烧焦的蔗中比未烧焦的蔗中增加。NCo334品种在各贮藏期蔗重、脂、汁纯度、可回收糖和糖产量的损失均较大。两个品种在贮藏期内，焦化和未焦化收获的甘蔗的纯度、果汁纯度、可采糖率和糖产量均高于焦化收获的甘蔗。综上所述，n14甘蔗品种的焦化收获蔗和青蔗应在24和48 h内粉碎，以获得比nco 334品种更好的糖质。

Experiments were conducted on a split–split plot design with two varieties, N 14 and N Co 334 as main plots, types of canes burnt and unburnt green harvested canes as sub-plots, and eight cane storage periods (0, 24, 48, 72, 96, 120, 144, and 168 h) as sub–subplots with three replications. All quality parameters were investigated using the standard procedure. The results showed that the loss in cane weight increased and pol %, purity % juice, estimated recoverable sugar, and sugar yield decreased significantly with increasing periods of storage. The results also indicated that losses were more in burnt harvested canes than the unburnt canes over the storage period. Brix and reducing sugar in juice increased with the storage periods and these were more in burnt canes than unburnt harvested canes. The loss in cane weight, pol, juice purity, recoverable sugar, and sugar yield was high in NCo334 variety at each storage period. The pol and purity % juice, recoverable sugar % cane, and sugar yield were more in burnt and unburnt harvested canes in both varieties at storage periods. The findings suggested that the N 14 cane variety of burnt harvested canes and green canes should be crushed within 24 and 48 h to obtain better sugar quality than N Co 334 variety.","PeriodicalId":10521,"journal":{"name":"Cogent Food & Agriculture","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135816154","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}
The rising number of individuals diagnosed with type 2 diabetes is a global health concern. This chronic disease can lead to a diverse range of complications. In this study, we assessed the extracorporeal hypoglycemic mechanism as determined by the inhibitory activity of TGE (Fagopyrum tataricum grain crude extract) and TBE (Fagopyrum tataricum bran crude extract) on elevated blood glucose, oxidative stress and inflammatory response. In addition, to characterize hypoglycemic activity in vivo, we investigated the anti-diabetic effects of water—ethanol extracts of Fagopyrum tataricum grain and bran with flavonoid-rich and D-CI fractions in type 2 diabetic mice induced by streptozotocin and a high-fat/high-sugar diet. Moreover, compared with the TBE group through kit detection and in vitro test analysis, treatment of mice with TGE has a better ability of antioxidant activity, Reduce inflammatory overreaction, hypoglycemia, improving symptoms of type 2 diabetic mice and reducing organ damage. In conclusion, these findings yet indicate that TGE could be used to manage the disease, for the improvement of blood glucose level and exhibits antioxidant properties for type 2 diabetes. By providing a comprehensive review of the molecular mechanisms underlying glucose metabolism, oxidative stress, inflammation, organ structural damage, and insulin resistance in individuals with type 2 diabetes mellitus. Our findings not only offer a deeper understanding of these processes but also provide novel insights and theoretical guidance for the treatment of diabetes mellitus.

This study is aimed at determining the physicochemical and microbiological quality of stingless bee honey (Meliponula beccarii) collected in potential areas in the Oromia region of Ethiopia. Thirty-nine honey samples from underground soils were collected. The findings of the investigation indicated that the mean values of physicochemical properties for stingless bee honey samples were: moisture content (30.69 ± 0.29%), pH value (3.30 ± 0.03), free acidity (92.39 ± 4.45 meq/kg), ash content (0.16 ± 0.01%), electrical conductivity (0.44 ± 0.2 mS/cm), HMF (6.58 ± 0.36 mg/kg), fructose (36.48 ± 0.54%), glucose (27.67 ± 0.43%), reducing sugar (64.15 ± 0.75%) sucrose (1.24 ± 0.18%) and maltose content (1.2 ± 0.18%). The honey sample studied from Meliponulla beccarii was mostly characterized as having a light amber color (50%). Honey produced by stingless bees is distinguished from Apis mellifera honey by having a lower level of sugar, a higher amount of moisture, and free acidity. There were 2.55 × 104 to 1.9 × 103 CFU/mL of Aerobic Mesophiles, 1.68 × 104 to 9 × 102 CFU/mL of yeast, and 1.8 × 103 to 2 × 102 CFU/mL of mold in the Meliponulla beccarii honey sample. Staphylococcus species could only be detected in a sample taken from the Guduru area; however, an aerobic spore-forming bacteria was undetectable in all stingless bee samples. This suggested that there may have been cross-contamination from primary and secondary sources during pre-harvesting and post-harvest handling. Specific quality specifications must be established to promote commercialization since the physicochemical and microbiological characteristics of stingless bee honey differ from those of A. mellifera.
