Vermicompost scheduling on nutrient uptake at different growth stages of rice crop were assessed at two field experiments conducted during 2011-12 and 2012-13 in the Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Different levels of vermicompost along with nitrogen (N) were included in the study. Initially higher nutrient availability in soil in these treatments responded well to plant growth and plant nutrient contents and a significant variation in dry matter accumulation and plant nutrient contents was noticed. Since dry matter yield and nutrient content were maximum/significantly higher in these treatments therefore significantly higher nutrient uptake is obvious. Application of sub optimal level of inorganic N also reflected its impact on dry matter production, plant nutrient content and there by recorded lower quantities of plant nutrient uptake by recorded lower quantities. The nutrients uptake in plant samples at different growth stages differed significantly with the application of Vermicompost and NPK. Plant nutrient uptake was declined with the advancement in crop growth. Plant nutrient uptake was higher in T2 (100% NPK) at different growth stages of rice during both the years while minimum was found in control. Plant iron, zinc, copper and manganese uptake at different growth stages differ significantly with the application of different treatments. The maximum plant uptake of these micronutrients during entire growth period was found with the application of 100% NPK and it was followed by T3 where Two ton vermicompost was applied as basal.
