ABSTRACT: Asparagus racemosus is an important medicinal plant commonly called Satavari considered both a general tonic and a female reproductive tonic with ability to increase fertility and vitality. Charak Samhita written by Charak and Ashtang Hridyam written by Vagbhata, the two main texts on Ayurvedic medicines, list Asparagus racemosus as part of the formulas to treat women’s health disorder. Due to its multiple uses, demand for A. racemosus is constantly on the rise  however, the supply is rather erratic and inadequate. Destructive harvesting, combined with habitat destruction in the form of deforestation has aggravated the problem. There is a need for conservation of this plant. To overcome these prevalent problems, the availability of genetically superior and uniform planting material is essential. The seed mediated propagation is unsatisfactory due to dormancy and low germination percentage. This however, decelerates the conservation strategy of this species. Thus efforts were made in this study to break dormancy and improve germination of seeds by different growth regulators for boosting conservation. The TZ (Triphenyl tetrazolium chloride) test showed 97%  of viable seeds. The present investigation was carried out to study the influence of different growth substances on seed germination, length of root and shoot and vigour index. The seeds were soaked in different growth regulators like GA3, NAA & KNO3 with different concentration to evaluate their effect on germination at a constant temperature of 250C, it was found that GA3 300 ppm had a highest significant effect on germination as compared to control and all other treatments at a constant temperature on top of the paper substrata, but as the concentration increased above 300 ppm the germination decreased rapidly.

Abstract: The emergence of a global energy crisis and the enormous risk of climate change have significantly jeopardized the survival and development of the human race. Pervasive human activities, as a result of unchecked population growth and expanding industrialization, have resulted in an enormous increase in overall environmental degradation. Thus, itis now widely recognized that economically viable and environmentally benign strategies are necessary to address the current climate issues worldwide. Existing approaches to addressing this result in the generation of secondary pollutants, causing an insufficient resolution of the problem. Thus, the utilization of biomass-derived nano-structured materials emerges as the most effective approach for achieving an effective remediation strategy, realizing the circular economy, and achieving sustainable development goals.

Abstract: The water extract of compost termed “compost tea” retains all the beneficial soluble bioactive components, making it a potent source of plant stimulatory and defensive compounds. High quality compost refers to compost that is high in microbiological activity. Compost tea is made by two brewing methods; non-aerated method and aerated method. For both methods of compost tea production, microbial food may or may not be added. Numerous studies have demonstrated that composted materials and their resulting teas can provide manifold benefits as organic fertilizers in sustainable agriculture. Indeed, compost teas have been shown to suppress a wide range of soil-borne diseases when used as foliar sprays and soil drenches, thereby ultimately affecting plant growth and yield. The exact nature and extent of these features are, however, modified by composting system, feedstock quality, tea preparation and resultant use and management, including application dynamics of the compost tea. The purpose of this work is therefore to give an overview of the factors affecting the quality and efficacy of compost tea in organic agriculture. The objectives of this review are to identify the process, operational and environmental parameters that influence the quality and efficacy of compost tea, describe compost tea characteristics and quality assessment, and to summarize the current knowledge of compost tea application including; application methods, application rate and application time.

ABSTRACT: There is drive and momentum to implement changes in the public sector organizations and for such changes it is first and foremost dilemma to analyze the performance management system and practices implemented in such organizations. This study explores the performance management system at National bank of Pakistan. It’s a descriptive study and main focus of this study is to identify the flaws in performance management system that are currently prevailing at National bank of Pakistan and suggesting new ideas to bring positive changes ultimately getting competitive advantage through Human Resource Management (HRM). For analyzing the study, a sample of 100 employees has been selected on convenient basis form Bahawalpur Region and reposes are obtained on the fully structured questionnaires and analyze the results through Chi-Square technique.
