Effect of Different Levels of Nitrogen and Zeolite on Soil Properties and Soil Fertility for Rice Cultivation

The pot culture experiment was conducted to investigate effect of different levels of nitrogen and zeolite on soil properties in rice under greenhouse condition during kharif 2018-19. The investigation showed that soil bulk density was decrease from 1.5 to 1.02, 1.24 and 1.29 g cc-1 by the zeolite application at 9, 6, and 3 t ha-1 respectively. Water holding capacity of soil was increased from 43.53 to 55.49% with different levels of zeolites. Cation exchange capacity of soil significantly increased by 50.45, 44.54 and 29.22% with the application of zeolite at 9, 6 and 3 t ha-1, respectively. Highest value of soil pH and EC were 7.6 and 1.27 dS m -1observed in 9 t ha -1 zeolite treatment. Fertility status of soil i.e. available nitrogen and available phosphorus content also improved by the application of zeolite at different rates.
