The current study was carried out at the experimental farm of Rice Research Department, Sakha Agricultural Research Station and Central Agricultural Pesticide Laboratory, ARC, Egypt during the summer season of 2021 and 2022 to study the sensitivity of three Egyptian rice cultivars against four common herbicides and its effect on physiological and agronomic characteristics of rice as well as herbicide residues in rice seeds. The field study was laid out in split plot design with three replications. Three rice cultivars (Giza 177, Giza 179 and Sakha 108) were randomly distributed in main plots, while weed control treatments included four herbicides at recommended doses (penoxsulam 2.5% OD, bispyribac-sodium 2% SL, cyhalofop-butyl 10% EC and fenoxaprop-p-ethyl 7.5% EW) as compared to hand weeding were devoted in sub plots. The obtained results revealed that Sakha 108 as Japonica rice cultivar was resistant against tested herbicides and recorded the highest values of rice dry weight, chlorophyll content, number of panicles m-2, panicle weight and grain yield, while scored the lowest values of total phenols. On the other hand, Giza 177 as short duration Japonica rice cultivar showed the higher sensitivity against tested herbicides and achieved the lowest values of abovementioned agronomic traits and chlorophyll content. Cyhalofop-butyl as ACCase herbicide was safer on studied rice cultivars and recorded the highest values of studied agronomic characteristics for rice as well as chlorophyll content, while recorded the lowest values of total phenols during the study. On the other hand, bispyribac-sodium 2% SL resulted in more toxic effect for rice cultivars and recorded the lowest values of studied agronomic traits for rice. fenoxaprop-p-ethyl 7.5% EW achieved the lowest chlorophyll content and highest values of total phenols during the study. Giza 179 as Indica-Japonica rice cultivar appeared high sensitivity when sprayed with bispyribac-sodium and fenoxaprop-ethyl but made recovery after 12 days from herbicidal application and recorded the highest chlorophyll content, dry weight, panicles m-2 and grain yield with no significant differences between Sakha 108 rice cultivar during the study. In respect of herbicide residues in rice seeds, all tested herbicides didn’t have residues in rice seeds at 100 days after treatment. It means that tested herbicides didn’t have any residues in rice seeds.

“…About 30 million tonnes of dry beans are generated annually throughout the world, particularly in tropical regions of India, Brazil, Myanmar, China, the United States, and Mexico [42]. The processing of sweet corn results in the beneficial byproduct of corn cobs [43]. Because of its nutritional value, maize cob may be utilized as a substrate for the growth of microbes or transformed into molecules that have additional benefits, such as lactic acid, citric acid, sugars, ethanol, and enzymes [31,36,[44][45][46].…”

Three possible novel Didymella species, isolated from Mango and Guava juices in Assiut, Egypt, were identified based on morphology and sequencing of the internal transcribed spacers region (ITS). The three strains could ferment five lignocellulosic residues, namely bean straw, corn cobs, rice husk, wheat bran, and wheat straw in solid-state fermentation (SSF) and produce cocktail enzymes (endoglucanase, exoglucanase, laccase, pectinase, and xylanase). Didymella sp. AUMC 15636 and AUMC 15637 produced the most endoglucanase, exoglucanase and xylanase activity (20 and 23, 10 and 17, 18 and 18 U/gds, respectively) on bean straw, and laccase (0.7 and 2.6 U/gds) on corn cobs and wheat bran, in addition to pectinase (37 and 26 U/gds) on rice husk and corn cobs, respectively. Didymella sp. AUMC 15640 released the maximum endoglucanase, exoglucanase, laccase, pectinase, and xylanase enzymes on the bean straw residues (24, 24, 10, 31 and 27 U/gds), respectively. Didymella sp. AUMC 15636 yielded 0.9 g crude pectinase per liter fermentation medium in submerged fermentation (SmF). At pH 6.0, a peak in pectinase activity (80 U/gds) was detected, which rose to 100 U/gds at 45 ºC. Presence of Mn 2+ ions activated the pectinase by 30% over the control. Zn 2+ and EDTA had no effect on pectinase activity, while sodium dodecyl sulfate and other ions lowered pectinase activity by 10 to 30%, while K + and Ca 2+ having the highest impact. The target of this study, which is advocated here by utilizing such strains, is to

This study was conducted at Rice Department farm, Sakha Agriculture Research Station during 2018 and 2019 seasons. Yield and yield components, grain quality, cooking quality, chemical composition with nutrition content were estimated in this study for two Egyptian varieties (Sakha 108 and Giza 182) and introduced Black Rice variety. The results showed that, Sakha 108 variety had the best grain quality characters (hulling %, milling% and head rice %) with high performance of grain yield. Giza 182 as indica type gave the good performance in yield and yield attributes. Black rice as introduced one had high levels of protein, ash, oil and minerals (iron, calcium and zinc) as nutritional elements compared with the other two varieties in both seasons, while the fiber crud percentage reached to the maximum for Sakha 108 in brown grains while the total carbohydrate was high in milled grains of Sakha 108. On the other hand, Giza 182 variety milled grains recorded the lowest content of minerals except for Ca. For cooking quality characters, results indicated that milled grains of Giza 182 gave the highest value of water uptake and produced the greatest volume expansion. Sakha 108 and Giza 182 brown and milled grains had the same time for cooking, while Black Rice variety grains gave the highest value for cooking time.
