Definition Wild edible plants (WEPs) grow naturally in self-maintaining ecosystems. WEPs are harvested for consumption, sale, and medicinal uses. We hypothesize that WEPs play a major role in supplying food and generating income for the rural people in a world that is increasingly recognising its emerging conservation issues. We tested this hypothe...

With series of macro-invertebrate studies, Epiophlebia laidlawi Tillyard, 1921 is recorded from Trashigang (Gomchu stream) and Trashi Yangtse (Gellingchu, Mangchi and Chuthakang), districts in eastern Bhutan. Its abundance is higher in post-monsoon season. The pH of the water from Gom-chu stream ranged from 6.63-7.50, electrical conductivity from 1...

Owing to the role played by biofertilizer in crop productivity, an increasing area of research on the use of beneficial microbes as biofertilizers is increasing in agricultural sector. Hence, the study was conducted to test the efficacy of Azotobacter biofertilizer on popcorn (Zea mays var. everta). A pot study was conducted in an artificial greenh...

Biofuel, the source of energy for the future, is a renewable source of energy. Generally, it is extracted from plant biomass as biooil, biogas, biodiesel, and bioethanol. Invasive species have been contemplated as a promising source of feedstock for meeting future biofuel production demand. Invasive plant species demonstrate suitable characteristic...

Biohythane, the blending of biohydrogen—biomethane with hydrogen concentration ranging in between 10% and 30% (v/v). It can be generated via utilizing various organic substrates through two-stage sequential anaerobic stages, that is, the dark fermentation step followed by the anaerobic digestion step, for biohydrogen and biomethane production, resp...

This paper critically explores into five important aspects of wild edible plants (WEP). It dwells on general research and development in the field of wild edible plants, their roles as a source of food and nutrition supply and avenue of income generation for the local community. It also looks into their resilient characteristics to the impact of cl...

With series of macro-invertebrate studies, Epiophlebia laidlawi Tillyard, 1921 is recorded from Trashigang (Gomchu stream) and Trashi Yangtse (Gellingchu, Mangchi and Chuthakang), districts in eastern Bhutan. Its abundance is higher in post-monsoon season. The pH of the water from Gomchu stream ranged from 6.63-7.50, electrical conductivity from 18...

White Rust of Crucifers is caused by Albugo candida, which causes damage to quality and quantity of the produce. Conventionally, fungicides are applied to reduce disease incidences; however, improper and excessive use of chemical fungicides can be detrimental to the environmental health. In this study, different concentrations (2.5%, 5%, 7.5% and 1...

According to the UNDP's human development report (2009), at six percent, Bhutan's internal migration rate is the highest in South Asia. Therefore, rural-urban migration is a serious problem and is faced by every pockets of the country. To this end, rural-urban migration has seriously undermined traditional socio-religious and cultural values back i...

This paper endeavours to find out the research culture pinning down to the students of B.Sc. life sciences. Data on research culture was collected through questionnaires from B. Sc Life Science students, focusing on their interest, motivation and support on research by the college, relevancy of research on their syllabus and their opinion on the im...

Heavy metal pollution is a serious environmental issue today. Recognizing the ability of microorganisms and biological materials to remove them from the polluted sites makes it cheaper method of heavy metal remediation. Microorganisms remove metals as a result of biosorption and bioaccumulation. In the present work, filamentous yeast Trichosporon c...

This action research was conducted by a trainee teacher (Post Graduate Diploma in Education, PGDE) while in the school for teaching practice. It exploits the scope of action research to overcome my shortcomings of crude personality to a successful teaching in class. It focuses on the problem of "student to teacher interaction" in classroom. The tea...
