Over-under Ground Biomass Characteristic of Perennial Species (Paronychia kurdica) in Northwest Iran (Till Area of Shabestar)

Hamideh Shadkami-Til and Ghassem Habibi Bibalani    

Abstract: Knowledge of the process of change in vegetal biomass in perennial plant species is indispensable in a sound of range management. Research area is of rangeland of Til village from Shabestar distract with distance is 25 km from it. This area is semi arid area and this land covered with natural range land grasses. Root and shoot in these species were sampled in one stage from late March to late August roots of plants stable soils on slope and provide resistance against the forces that improve slope instability. The aim of this study was to assess which biomass quantitative is associated with differential productivity of P. kurdica species. In the research, Paronychia kurdica biomass was been studied in under-ground plant biomass in soil studying of area with measure dept of roots and height of stems, vegetal sample was collected form studying area with random plot 1x1 m statistical plant during one the vegetative season in this research. Results of this research showed plant average root dept is about 9 cm, average stem height is about 11.45 cm and average under ground of plant biomass is about 0.12 g m-2 and average over ground of plant biomass is about 0.55 g m-2.
