Comparative study of the mycelial characteristics of Pleurotus species with the first time description of anamorphic stage of Pleurotus cystidiosus from Pakistan

Paper ID- AMA-05-08-2021-10528

In the present study, potentially edible and nutritious Pleurotus spp. i.e., P. cystidiosus, P. floridanus, P. ostreatus were collected to figure out their cultural characteristics and to find out the optimum requirements for their mycelial growth which are the pre-requisite requirements for their successful cultivation. Their mycelial features were observed on the different nutrient media at different temperatures. Mycelium of each species was assessed morpho-anatomically. Mycelium growth pattern and texture of three Pleurotus species were irregular and cottony while a special anamorphic stage (Antromycopsis macrocarpa) in the form of Coremium and coremioliquid appeared during the cultural growth of P. cystidiosus. Anatomically mycelium of each species was septate and clampedwith the addition of toxocyst and arthroconidia production in the anamorphically grown myceliumof P. cystidiosus, which is unreported feature for this species from Pakistan. P. floridanus took more time to completely colonize the petriplates on all media followed by P. cystidiosus and P. ostreatus. All species have spawn production potential but spawn production rate was more of P. ostreatus followed by P. floridanus and P. cystidiosus. The linear growth rate was assessed on the mixed substrate of sawdust and wheatstraw. P. floridanus, P. ostreatus, P. cystidiosus mycelium showed their best colonization rate at 16ᵒC, 22ᵒC, and 28ᵒC respectively. From these results it could be assessed that these nutritionally and medicinally significant Pleurotus spp. possess the cultivation potential and their cultivation on large scale can meet the nutritious need of the growingpopulation of the world.

Essential oil of Thymus zygis: Chemical composition and biological valorization proposals

Paper ID- AMA-05-08-2021-10527

The chemical composition of the essential oil extracted from the dried aerial parts of Thymus zygis harvested from the Khenifra region (central Middle Atlas of Morocco) was studied by gas chromatography coupled with mass spectrometry (CPG and CPG / MS). Fifty-four (54) constituents, representing (99.98%) of the essential oil have been identified. The majority compounds are: Linalool (4.79%), Camphene (4.00%), Thymol (38.59%), Carvacrol (4.69%), o-cymene (19.11%) and β-E- ocimene (10.20%) with a total percentage of 81.38%. The insecticidal activity was achieved against Aphis fabae. This preliminary study showed that the essential oil of Thymus zygis has a high toxicity towards this insect. The results of the tests showed a very important activity during 24 hours of the treatments confirmed by the values of LD50 and LD90. This activity was probably due to its major constituents. The antibacterial activity was studied in vitro against gram-positive bacteria, Bacillus subtilis (CECT 498) and Staphylococcus aureus (CECT 240), gram-negative bacteria, Escherichia coli (CECT 516), and Micrococcus luteus (CECT 244). The results of the tests helped to quantitatively assess the antibacterial activity by searching for minimum inhibitory concentrations of MIC and minimum bactericidal concentrations of CMB, which have a variable activity depending on the strain tested. The study of the antioxidant activity of Thymus zygis oil compared with the usual antioxidants α-tocopherol and ascorbic acid showed that this oil has an antioxidant effect.

The aimed of research to find was treatment organic matter (sugar cane bagas) and non non organic matter to water capacity of soil to soybean, to find the optimal soil moisture of the alfisol soil with organic matter (sugar cane bagas) and non-organic matter (sugar cane bagas) what are available to crop growth and yield. The results show that there is a significant interaction between the treatment of organic material and the water volume on the dry weight of the total of plant (the age is 2 weeks after planting), the ratio of wide leaf (the age is 2 and 4 weeks after planting), and the number of seeds. On the other hand, there is no interaction with other components. The treatment of water volume has real influence and it is really seen on all growth components and products except for the relative rapid growth of plant which has the weight of 100 seeds and harvest index. The best treatment of water volume is seen on the giving of water volume on field capacity and 500 ml. On the other hand, the treatments of organic matter tend to show a good result rather than without giving organic matter even though most of them are not real.

Extending the theory of planned behavior to assess farmers intention to adopt sustainable agricultural practices: evidence from cocoa farmers in Côte d'Ivoire

Paper ID- AMA-05-08-2021-10525

To counter climate change and achieve sustainable agriculture goals, farmers must follow sustainable agriculture practices. Several factors have been described as influencing farmers' decisions to adopt sustainable agricultural practices, but adoption remains poor, especially in Africa. Based on the theory of planned behavior extended with constructs from the Norms Activation Theory, we investigate the adoption of sustainable agricultural practices by cocoa farmers in Côte d'Ivoire. The data was derived from a survey of 570 cocoa farmers conducted in 2020. We used structural equation model (SEM) to look for correlations between variables. The results indicate that subjective norm, personal norm, attitude, and perceived behavioral control are significantly positively correlated with farmers' Intention toward Sustainable Agricultural Practices and that farmers' personal ecological norm is affected both by the Awareness of the consequences of their action and their subjective norm when their attitude is only affected by Awareness of the consequences.

Investigation of nonlinear vibration behaviors of FG micro-beams subjected to axial compressive force and resting on elastic foundation

Paper ID- AMA-05-08-2021-10524

This study presents analysis of nonlinear vibration of functionally graded (FG) micro-beams subjected to axial compressive load and resting on elastic foundation in framework of the Euler-Bernoulli beam theory (EBT) and nonlocal strain gradient theory (NSGT). The FG micro-beam composed of two materials including metal and ceramic is considered in which, the material properties change according to a simple power law of the coordinate in the thickness direction. The expressions of nonlinear frequencies of the FG micro-beams with simply-supported (S-S) and clapmed-clamped (C-C) boundary conditions are obtained in the analytical forms. The accuracy of the obtained results for the FG micro- beams is verified by comparing the obtained solutions with the published ones. Influences of some important parameters on the nonlinear vibration responses of the FG micro-beams are examined and discussed.
