Phyto-ecological studies are essential in understanding community structure, organization and their response to changes in other environmental factors. In this study we analyzed the phytosociological and soil characteristics of Phytolacca acinosa communities and their correlation. 110 quadrats were laid across ten randomly selected sites in Kashmir Himalaya, India. Soil analysis was done using standard protocols. Overall, 161 species were recorded, belonging to 128 genera and 49 families. The species richness (SR) ranges from 27 to 83. Highest IVI was recorded for Poa angustifolia (60.06) and least for Berberis lycium, Abies pindrow, Plectranthus ragosus, and Ailanthus altissima (0.37 each). P. acinosa showed 100% random associations with other plant species. Soil properties varied significantly across the selected sites. Significant positive correlation was found between species richness (SR), Organic matter (OM) (r = 0.79), Organic carbon (OC) (r = 0.79) and Shannon–Wiener index (H) (r = 0.92). Nitrogen content also showed positive correlation with SR and H. Floristic composition of P. acinosa assemblages was governed by soil properties and habitat characteristics of sampling sites. Areas with highest floral diversity had high soil fertility while areas with low soil fertility possess lower diversity and need restoration. The knowledge may prove helpful in management of these habitats, boost conservation and mitigate the effects of changing climate.

Agriculture is the backbone of India’s economy in general, and Kashmir’s economy in particular. It has an enormous potential for future growth and job creation. Kashmir has been home to diverse agricultural crops, both Kharif and Rabi. Rice, the people’s staple food, has been the most important crop cultivated in Kashmir, followed by maize and wheat, because of comparative benefits such as the ability to grow it in a wide range of habitats, simple cultivation requirements, easier processing, nutritional characteristics, and taste. The present study revealed that 75 crop species belonging to 58 genera and 18 families were cultivated in Kashmir valley. These crops include cereals, pseudo cereals, cash crops, vegetables, oilseeds, and fodder crops.

Introduction: Phytolacca acinosa Roxb. is a highly valuable multipurpose herb native to the Himalayan region. Unsustainable harvesting of this species due to its diverse uses has resulted in a rapid decline in its population across natural habitats, thereby necessitating its propagation and conservation. To overcome this challenge, the potential of P. acinosa rhizomes for ex situ regeneration was evaluated.Methods: The current study aims to develop a standard propagation protocol for P. acinosa. Rhizome cuttings derived by splitting whole rhizomes were used to study the effect of various hormones and soil compositions on their sprouting and growth performance.Results: Soil compositions SC10 and SC5 consisting of soil, sand, pebbles, and vermicompost (1:1:1:1) and soil, sand, and vermicompost (1:1:1), respectively, were the most suitable compositions for the optimum growth of this species. The rhizome segments treated with GA3 (150ppm) induced the highest sprouting percentage (91.67%), with a minimum sprouting time of 23.25 days. The maximum root length (9.25 cm), shoot length (16.5 cm), and leaf number (11.25) were recorded for GA3 (150ppm) treated rhizome cuttings.Conclutions: Overall, the results of the present study helped in establishing a cost-effective, rapid, efficient, and simple mass propagation method for the target species. The results of this study will serve as a guide for the large-scale cultivation, effective conservation, and sustainable utilization of this economically valuable medicinal herb.
