A random quadrat sampling method was used to assess the presence-absence of species. The study was conducted at Khatoed and Khamaed gewogs (blocks), Gasa District between January and December 2018. Identification of medicinal plant species and families were done in consultation with a botanist at the herbarium in Thimphu and volumes of Flora of Bhutan were referred. Based on the published and authentic scientific literature, information on medical uses of plant parts was collected. A total of 74 species of medicinal plant species in the wetlands, distributed in 69 genera and 43 families have been recorded. The study suggests preserving invaluable wetland medicinal plants and integrating ethno-medicinal practices in our lives.</p> Sangay Tenzin, Pema Tendar ##submission.copyrightStatement## Wed, 24 Feb 2021 00:00:00 +0000 Application of Guano Fertilizer and Types of Mulch on Growth and Yield of Potato (Solanum tuberosum L.) <p><strong>Aims: </strong>The purpose of this study was to obtain the best interaction between guano doses and mulch on the growth and yield of potato plants.</p> <p><strong>Study Design: </strong>The experimental design used was factorial 2 factors in a completely randomized design (CRD).</p> <p><strong>Place and Duration of Study: </strong>This experiment was carried out in Alahan Panjang, Lembah Gumanti District, Solok Regency, West Sumatra from March to June 2018.</p> <p><strong>Methodology: </strong>Factorial design 2 factors was use in research. The first factor consisted of 4 levels of guano fertilizer doses of 0, 3, 6 and 9 t ha-1. The second factor consisted of black silver plastic mulch and black plastic mulch. Data were analyzed statistically with the Fisher test and if significantly different then continued with the Duncan’s New Multiple Range test (p≤0.05)</p> <p><strong>Results: </strong>No interaction between guano fertilizer and the two types of mulch tested with</p> <p>respect to plant height, number of leaves, and smallest tuber diameter were observed. Guano fertilizer at 9 t ha-1 gave the best influence on the number of tubers and the diameter of tuber. Black plastic mulch had the best influence on the number of tubers, the diameter of tuber, the weight of tubers per plant and the weight of tubers per hectare.</p> <p><strong>Conclusion: </strong>The dosage of guano fertilizer of 9 t ha-1gave the best effect on the number and diameter of tubers. The type of black plastic mulch gave the best effect on tuber number, tuber diameter, tuber weight per plant and tuber weight per hectare.</p> Adinda Wahyuni, Netti Herawati, Warnita Warnita ##submission.copyrightStatement## Wed, 24 Feb 2021 00:00:00 +0000 Evaluation of Different Chaba (Piper chaba) Germplasm for Growth and Yield Performances <p>Genetic diversity is the base for survival of plants in nature and for crop improvement. Diversity in plant genetic resources provides opportunity for plant breeders to develop new and improved cultivars with desirable characteristics. Therefore, an experiment was employed to determine the genetic variability and evaluate the growth performing parameters of different Chaba germplasm at the research field of Regional Spices Research Centre, Bangladesh Agricultural Research Institute, Magura during kharif 1 season in 2018-19 following completely randomized design with three replications.&nbsp; Six germplasm namely PCmag-001, PCmag-002, PCmag-003, PCmag-004, PCmag-005 and PCmag-006 were collected from khulna region of Bangladesh and transplanted adjunct to different tree species mainly mango. Among the six germplasm heighest plant height (450 cm), number of branch (35), number of leaves (350), internodes length (16 cm) and vine diameter (2.5 cm) after one year of planting was recorded from PCmag-001 germplasm followed by PCmag-002 while the lowest plant height (450 cm), number of branch (35), number of leaves (350), internodes length (16 cm) and vine diameter (2.5 cm) were found from the germplasm PCmag-005. Through the observation of one year field trail in terms of growing characteristics the germplasm PCmag-001 and PCmag-002 can be chosen for future breeding material to release a commercial variety in southern part of Bangladesh.</p> Md.

Due to Telfairia Mosaic Virus <p><strong>Aims:</strong> To assess limitation on growth and yield of <em>P. vulgaris </em>due to Telfairia mosaic virus (TeMV).</p> <p><strong>Study Design: </strong>The study was conducted in a randomized block design.</p> <p><strong>Place and Duration: </strong>Department of Botany, University of Calabar, Calabar, Nigeria between April and August, 2016.</p> <p><strong>Methodology:</strong> Seeds of <em>P. vulgaris </em>were obtained, sorted, planted in polyethylene bags, and on germination, inoculated with TeMV, growth and yield limitation assessed at 2, 4, 6, 8 and 12 weeks after inoculation.</p> <p><strong>Results: </strong>Results showed that the virus decreased growth of <em>P. vulgaris </em>resulting in yield loses. Growth parameters were severely limited by TeMV with percentage reduction in Leaf area, shoot height, number of primary shoot, petiole length and number of leaves produced of 44.5%, 52.8%, 44.0%, 44.9% and 51.45 respectively at 10 weeks after inoculation (WAI). Leaf fresh weight (38.4%) and dry weight (32.3%) were significantly (<em>P=0.05</em>) reduced. Relative growth rate, net assimilation rate and leaf area ratio were negatively impacted by the virus with reductions of 26.5%, 36.7% at 4 WAI and 33.5% at 12 WAI respectively. Limitation on yield due to TeMV was significant (<em>P=0.05</em>) with reduction in pod length of 36.9%, number of pods per plant of 36.5%, number of seeds per pod of 26.5%, number of seeds per plant of 53.3% and weight of 100 seeds of 18.5%. Limitation induced on fresh and dry weight of shoot and root, pod width, seed length and seed width was not significant.</p> <p><strong>Conclusion:</strong> The study confirmed the threat of TeMV necessitating control of the virus on this important legume.</p> A.
