Abstract: The pot culture experiment was conducted at Department of Soil Science and Agricultural Chemistry, Mahatma Phule Krishi Vidyapeeth, Rahuri, India, to study the effect of silicon application along with chemical fertilizers on nutrient uptake and nutrient availability for rice plants. The soil samples from order Inceptisols and Vertisols were collected; 10 kg soil was filled in each plastic pot for study. The experiment was laid out in factorial completely randomized design having fourteen treatment combinations replicated thrice with rice as a test crop. The main treatments were soil types Inceptisols and Vertisols; sub treatments were levels of silicon with T1: Absolute control, T2: General recommended dose of fertilizers (GRDF) (100:50:50 kg ha-1 N:P2O5:K2O + 5 t ha-1 FYM), T3: GRDF + Si @ 25 kg ha-1, T4: GRDF + Si @ 50 kg ha-1, T5: GRDF + Si @ 100 kg ha-1, T6: GRDF + Si @ 150 kg ha-1, T7: GRDF + Si @ 200 kg ha-1. The soil samples from Vertisols and application of GRDF + Si @ 200 kg ha-1 showed significantly highest grain yield, straw yield, nutrient uptake (N, P, K and Si) also micronutrient uptake (Fe, Mn, Zn and Cu) over Inceptisols and other levels of silicon, respectively. The application of silicon along with chemical fertilizers enhanced the yield potential as well as residual soil fertility status at harvest of rice plants.
