Proper domestication and conservation measures is necessary to conserve the medicinal flora. Experimental trials to examine the growth of medicinal plants in the location: Swat and Chitral, wild habitats, fertilizer and control (no fertilizers). Data show that various treatments significantly effected plant Height (cm), plants density m-2, root yield kg ha-1, and Income Rs ha-1 in both the locations. The economical analysis of the data revealed that the maximum income for Glycyrrhiza glabra (840,000 PKR ha-1) and Trillium govanianum (481,325 PKR ha-1) was recorded in NPK applied plots. Simlalry, minimum (220,000 PKR ha-1) for Glycyrrhiza glabra and (104,854 PKR ha-1) recorded for Trillium govanianum in their wild habitat in both the locations. Likewise, maximum morphological growth, yield and income of medicinal plants in Swat valley was higher than Chitral. Furthermore, the production of the medicinal plants in wild habitat is comparatively lower and thus improved production technology is suggested to get higher yield. The findigs revealed that Swat valley is most suitable and productive for the cultivation of medicinal plants as compared to the location Chitral. In addition, growing medicinal plants will be popularized among the farming communities of Pakistan and the gerplasm of these endangered species will be conserved for future use. Key words: Medicinal plants, Endangered wild flora, domestication, cultivation, conservation.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85995002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant contains huge number of phytochemicals i.e. amino acids, fiber, minerals, vitamins, secondary metabolites, bioactive proteins and peptides which could be used in various medicine for human and other animal’s health. In addition, it has been reported that the quinoa leaves, root, and seed are used in the treatment of diabetes, cancer, inflammations, fungal infections, and other numerous health problems. Besides, its high energy, nutrient content, therapeutic properties, and lack of gluten, it is considered to be useful for children, the elderly, lactose-intolerant people, and osteoporosis in women. This comprehensive study provides medical uses, phytochemical constituents, and pharmacological activities of quinoa. Also, the anti-inflammatory, antimicrobial, anti-diabetic, anti-oxidant, anti-tumor, anti-lipidemic, antibacterial, and antifungal effects have been reviewed. This review is providing the detail study about the phytochemicals and pharmacological evaluation of quinoa till date, and also provides pave for future investigations and exploitation of Chenopodium quinoa.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73855020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fungus was grown in two growth media viz. potato dextrose broth (PDB) and malt extract broth (MEB) for two weeks. After filtration, the culture filtrates from both the media were used in original (100%) as well as diluted (50%) forms.

Weeds compete with plants for applied inputs and resources and resultant cause a significant reduction in final productivity. A study was conducted at Agronomic Research Area, University of Agriculture, Faisalabad. The study was comprised of two lentil varieties (Punjab Masoor-2009, Punjab Masoor-2020) and seven treatments i.e., weedy check (control), manual weeding, Pendimethalin 33 EC @ 247 ml ha-1, S. metolachlor 960 EC @ 1976 ml ha-1, Pendimethalin +S. metolachlor @ 2223 ml ha-1, Flumetsulam 80 WG @ 18.525 g ha-1 and Flumetsulam 80 WG @ 24.7 g ha-1 arranged in RCBD design having 3 replications. According to the findings, different herbicides and cultivars had a substantial impact on growth and yield attributes of lentil. The maximum root fresh and dry weights (8.07, 1.57 g), shoot fresh and dry weights (20.08 and 5.28 g), plant height (62.05 cm), pods/plant (67.83), grains/pod (2), 1000 seed weight (25.17 g), grain yield (1934 kg ha-1) and biological yield (3730 kg ha-1) was recorded in manual weeding and lowest root fresh and dry weights (6.28 and 1.57 g), shoot fresh and dry weights (12.33 and 3.99 g), plant height (44.58 cm), pods/plant (42.83), grains/pod (1.17), 1000 seed weight (14.40 g), grain yield (1113 kg ha-1) and biological yield (2830 kg ha-1) was recorded in weedy check. In case of cultivars, Punjab Masoor-2020 had maximum root fresh and dry weights (7.90 and 1.81 g), shoot fresh and dry weights (17.17 and 5.02 g), plant height (54.99 cm), pods/plant (60.43), grains/pod (1.67), 1000 seed weight (21.09 g), grain yield (1690 kg ha-1) and biological yield (3402 kg ha-1) while cultivar Punjab Masoor-2009 had minimum root fresh weight (6.53 g), dry weight (1.68 g), shoot fresh weight (14.57), dry weight (4.62 g), plant height (53.09 cm), pods/plant (48.76), grains/pod (1.33), 1000 seed weight (18.44 g), grain yield (1586 kg ha-1) and biological yield (3292 kg ha-1). Manual weeding also resulted in lowest weeds density and weeds biomass and weedy check resulted in maximum weed density and weed biomass.
