Food waste was composted with three additives consisting of phosphate sludge, green waste, and olive mill waste to produce a stable compost. To determine the stability for agricultural utilization, the compost maturity was evaluated using physic-chemical parameters. The temperature of treated composts remained high in the first month of composting. However, the pH was increased during composting to a slightly alkaline level around 8.0 instead of 9.31 in the control of food waste only. The integration of additives into the food waste composting has considerably reduced the electrical conductivity of the piles to optimal values less than 4 mS/cm. The C/N ratio decreased to less than 10 after 150 days, but the C/N ratio of the control (17.37) was two times higher than the enriched composts with additives composting indicating a good maturity of the composts enriched with additives. In addition, the additives significantly improved the stability of food waste during composting; the composts enriched with additives were thermostable more than 0.5 times than the control. The additive composed by a combination of phosphate sludge and olive oil mill waste showed greater effect on maturity and stability of the compost produced compared to other additives of only phosphate sludge and phosphate sludge + green waste.
The insecticide use by farmers raises the issue of the risks that these products pose to man and his environment, to clarify the status of these chemicals' use and to highlight the traditional agricultural practices of crop conservation. We conducted surveys in 2 Moroccan regions, Casablanca-Settet and Fez-Méknes, among the rural population. The investigation covered 800 people, 79% of them were men. The most representative age group was 40-60 years old (54%), farmers were the group most represented in the sample surveyed (78%) in which the illiteracy rate was higher (43%). Our results show that the choice of storage location and method plays an important role in seed conservation, 24% of the population uses underground tanks (matmouras) as a traditional practice for efficient storage without insecticides, for other methods, insecticides are mandatory to control phytophagous insects which present 73% of all pests. As for pesticide use, only (7%) of the respondents received simple knowledge about insecticides, so that most farmers (88%) buy these products from uncontrolled (weekly souk) or unauthorized sales points and that (99%) of farmers do not respect the prescribed dose during application, the number of repetitions and the time between two successive repetitions. Most handlers (77%) do not take sanitary precautions during use and packaging is released directly into the surrounding environment in most cases (68%).
Several advancements were achieved from natural products chemistry over the years and all over the world and although exploration of natural products was more focused on its application in the medical field, studies on its use in the cosmetic industry, primarily on anti-aging and whitening, have also been performed especially now that the cosmetics market is moving towards the green cosmetic trend. Inflammation plays a major role in intrinsic human skin aging while tyrosinase serves as a key player in the color development of the skin because of its role in melanin production. With this, the study aims to assess the potential of different extracts of Asystasia gangetica which is abundant in biologically active components such as phenolics, flavonoids, saponins, and tannins as a source of cosmetic products that are anti-aging and whitening in order to provide new information that will be valuable in green cosmetic research. To do this, different extracts of A. gangetica were utilized to treat RAW 264.7 cells to assess their anti-inflammatory activity and are reacted with tyrosinase solution and L-DOPA substrate to examine its anti-tyrosinase activity. The findings showed that all extracts except for aqueous exhibit anti-inflammatory property with methanol extract being the most favorable, while only three extracts exhibited inhibitory effect against tyrosinase, with ethyl acetate extract being the most promising with an of 0.19 ± 0.013 mg/mL. In conclusion, A. gangetica has the potential to act as an anti-aging and a whitening agent and may be essential in further development of green cosmetics.

The edible and wild mushrooms are recognized as important source of anticancer agents. Our aims are to harness methanolic extracts of Agaricus bisporus (ABME) and to test for anticancer effects in HeLa, MCF-7 and MDA-MB-231 cell lines. To test anticancer effect of this extract, we adopted some methodology such as cell morphology study by bright field microscope, nuclear morphology study by DAPI staining under inverted fluorescence microscopy, apoptosis assay by fluorescence technique, MTT assay, lactate dehydrogenase assays, and expression of apoptotic and anti-apoptotic genes by Western blotting. The results showed that under a phase contrast microscope, the cells from the three cancer cell lines exposed to 500–1000 μg/ml concentrations of ABME for 24 h, were round and shrunken. DAPI staining revealed that nuclei in the three treated cell lines were condensed, fragmented and deeply stained. MTT assay revealed that the growth of all three cell lines was inhibited at all tested concentrations of ABME; at 1000 µg/mL, the percentages of inhibition in HeLa, MCF-7 and MDA-MB-231 cell lines were > 80%. Under 500 µg/mL ABME exposure, LDH leakage in all three cell lines; increased expression of pro-apoptotic genes (Caspase 3, 9) and Bax; and decreased expression of BcL2 in MCF-7 cells validated the anticancer properties. The p53 gene was up-regulated by ABME. The percentage inhibition of migration of MCF-7 cells treated with ABME was 75.25±5.23. The total antioxidant content of ABME was 3.616718±0.24123 mg/ dry weight; the EC50 was 95.653±9.54067 µg/mL for DPPH, and the FRAP method indicated a free radical scavenging capacity of it. GC-MS analysis of the extract showed 102 compounds. In conclusion, A. bisporus thus contains anticancer compounds, and its consumption may prevent cervical and breast cancer.

This paper studied about the general management of high density apple trees for higher production and greater quality of apple fruit in Himalayan regions with special reference to Kashmir valley. This paper focuses on the nature of soil and planting and sequencing of high density apple plants for efficient production. The paper used POSDCORB type technique for allocation of the high density trees. The higher density system is more expensive in the investment year, but total growing costs are less than the central leader system. The net results showed that there is no significant difference in the total establishment and growing costs and the internal rates of return are greater than many alternative long-term investment opportunities. The paper concludes that efficient management leads to greater production. It is not sufficient to have HD plants but management of HD plants is necessary for harvesting better results.
Objectives: The current study emphasizes synthesis of Zinc oxide nanoparticles using the bud extract of Syzygium aromaticum due to its higher Phenolic content and to observe its antibacterial activity against Escherichia coli, Bacillus subtilis, Bacillus cereus and Staphylococcus aureus.
Methods: The presence of polyphenols in bud extracts of S. aromaticum were analysed qualitatively and quantitatively by standard method, then the formed ZnO nanoparticles from clove bud extract were characterized. Finally, antibacterial activity of ZnO nanoparticles from clove bud extract were determined and statistical analysis was done by ANOVA.
Results: The clove bud extracts of S. aromaticum showed the presence of polyphenols by ferric chloride test. The amount of polyphenols present in the bud extract was found to be 118 mg GAE/g of dry weight for aqueous extract of clove and 180 mg GAE/g of dry weight for 80% methanol extract of clove. The formation of ZnO nanoparticles was done by using 80% methanol extract of clove which has higher phenolic content, characterized by UV Vis spectrophotometer showed an absorption peak at 224 nm and FTIR analysis showed peak at 650.01 cm-1. Morphology of synthesized nanoparticle was confirmed by SEM analysis and XRD spectrum showed diffraction peaks around 36.273° and the size of the nanoparticle found to be 123.84 nm. Antibacterial activity of synthesized nanoparticle showed its effectiveness against bacterial species was in the decreasing order of S. aureus > B. cereus > B. subtilis > E. coli. The statistical analysis of agar diffusion method for each bacterial species showed that there is a significant difference between standard (Chloramphenicol and Ampicilin) and Zinc oxide nanopartciles.
Conclusion: The current study reveals that, ZnO nanoparticles synthesized from bud extract of Syzygium aromaticum effectively inhibits Gram-positive and Gram-negative bacteria and could be used as an effective alternative to treat bacterial infections.
The effects of plant growth regulators were investigated on Kalanchoe blossfeldiana regeneration and then gene transferring was optimized. Three types of explants: leaf surface, vein and petiole and different concentrations of Benzyl Adenine (BA) and Kinetin (Kin) alone or in combination with Naphthalene Acetic Acid (NAA) were used for regeneration. Results showed that the highest number of shoots (47.33) and leaves (330.33) were obtained on Murashige-Skoog (MS) medium + 1.5 mg/L BA and 0.7 mg/L NAA. Maximum length of shoots (1.7 cm) was obtained from petiole explants on MS medium + 1.5 mg/L BA and 0.7 mg/L NAA. In medium containing Kin, adventitious root regeneration obtained from leaf explants. The most root number (21.12) and root length (1.56 cm) produced in MS+1 mg/L Indole Butyric Acid (IBA). For acclimation, the most length and leaf number increase percentage were obtained in peat-moss substrate. For optimization of β-glucuronidase-gene transferring, leaf sections and stems of in-vitro plantlets were used as explants for co-culturing in 10 and 30 min by Agrobacterium tumefaciense strain LBA4404 containing gus gene. The highest percentage of gene transferring and its expression (38.46%) was observed in leaf explants by 10 min co-culturing. So this protocol can be used for efficient gene transferring to this plant.

A healthy forest condition will depend on biotic and abiotic factors in the forest do not become a limiting factor in achieving the goals of current and future sustainable forest management. Healthy forest conditions include the presence of trees that thrive, are productive, fast accumulation of biomass and nutrient cycles, no significant damage occurs by plant-disturbing organisms, and the presence of a typical ecosystem. The management of protected forest health aims to integrate knowledge about ecosystems, population dynamics and genetics of plant-disturbing organisms with economic considerations to keep the risk of damage below the threshold of loss. In the last decade, mangrove forests on Seram Island, Saparua Island and the Islands of Southeast Maluku suffered damage due to anthropogenic pressure including illegal logging, livestock grazing, forest fires, erosion, flooding resulting in mangrove forests on the three islands unable to function as a regulator of water systems, and protection of the system life buffer. The impact of subsequent floods, erosion, decreased water flow, drought to decrease soil fertility on the three islands. This condition needs serious attention because the health condition of the forest will affect the lives of living creatures living in and around protected forests. Therefore, the specific goal to be achieved is to know the health status of mangrove forests on the three small islands in Maluku so that policy recommendation will give to parties related to managing mangrove forest areas in Maluku, especially in the face of climate change. By knowing the health status of mangrove forests, the relevant stakeholders will immediately set a strategic plan for managing mangrove forests on small islands in the context of disaster risk management to create communities around forests that are resilient to climate change and realize sustainable management of mangrove forests on small islands. In the last decade, most of the mangrove forests in Maluku experienced erosion, flooding during the rainy season and decreased water flow during the dry season, so the status, and health condition of mangrove forests should be known as an early warning for comprehensive conservation of mangrove forests.
