Abstract
The present study was designed to evaluate the effect of different concentrations of Silica gel on the growth and yield of Camelina sativa. A pot experiment was laid out in Completely Randomized Design (CRD) with three replications at Nanotechnology Laboratory, Department of Agronomy, PMAS Arid Agriculture University Rawalpindi. The experiment consisted of 4 levels (0.15 mg/g, 0.30 mg/g, 0.45 mg/g and 0.60 mg/g) of each mentioned nutrient along with control. The data were recorded and analyzed according to recommended procedure for following parameters viz., germination %, root and shoot length (cm), root and shoot biomass (g), relative water content of leaf and leaf membrane stability index. It was observed that 0.60 mg/g silica gel application increased the seed germination (80%), root length (6.67) cm, shoot length (35.33) cm, root biomass (1.7) g, shoot biomass (5.57) g, relative water content of leaf (0.69) and leaf membrane stability index (0.07). The study concluded that significant effect of silica gel application is crucial and important to improve vegetative attributes of false flax.

Summary
Agriculture is the backbone of country’s economy and plays vital role in economic growth and development. Camelina (false flax / gold of pleasure) scientifically termed as Camelina sativa L. is an oil seed crop of brasicaceae family (Wariach et al, 2013) with low agronomic-input use (Putnum et al, 1993). It has the unique and health favored fatty acid patterns, composed up of higher level linolenic acid and comparatively low erucic acid concentration (Zubr and Matthaus, 2002). Heavy, water logged, acid soils and lands having severe weed problem are not suitable for Camelina sativa cultivation (Lo ák et al (2011) With rapeseed, it is more resistant undesirable climatic conditions primarily drought and low temperature (Vollmann et al, 2007). Evidence is lacking concerning the physiological role of Si in plant metabolism
