Field experiment was conducted during rainy (Kharif) season 2008 at Jabalpur, M.P. to study the effect of various proportions of vermicompost and fertilizers on physiological parameters, growth, yield and yield components of scented rice. Total seven treatments viz., T1 = Control (no application of manure and fertilizers), T2 = 100% N through VC, T3 = 100% NPK through fertilizers, T4 = 20% N through VC+ 80% NPK, T5 = 40% N through VC+60% NPK, T6 = 60% N through VC+ 40% NPK, T7 = 80% N through VC+ 20% NPK. The experiment was laid out in Randomized Block Design (RBD) with four replications. The results revealed that applications of inorganic sources of nutrients remarkably increased growth, yield, yield attributes and physiological parameters of rice than application of organic sources of nutrients alone and different combination of organic and inorganic sources of nutrients. 100% NPK through fertilizers recorded significantly higher growth, yield, yield components and physiological parameters in comparison to other treatments and this was followed by substitution of proportion of NPK proportions (20% and 40% N with vermicompost). Application of 100% NPK through fertilizers was increased values of Leaf Area Index, Crop growth Rate, RGR, Net assimilation rate and dry matter production (g/m2), effective tillers/m2 (283.63), panicle length (23.59 cm), grains/panicle (86.90), test wt.(25.94 gm), grain yield (42.24 q/ha), straw yield (84.60 q/ha) over control. The lower physiological parameters, growth, yield and yield attributed was recorded in control.
