Abstract
Field experiment was conducted at Krishi Vigyan Kendra- Senapati, Manipur for two consecutive kharif seasons of years 2014 and 2015 to find out most efficient and economic combination of different organic and inorganic sources of nutrients to increase the productivity of maize (Zea mays L.) without deteriorating the soil qualities. Application of 100% NPK recommended dose of fertilizers in combination with biofertilizers (Azotobacter) and incorporation of vermicompost @5 t/ha improved soil physico- chemical properties (viz. decrease in acidic pH). This was also responsible for improving the nutrient status of soil in respect of available N and available P2O5 which were increased by 87 kg/ha and 14.08 kg/ha, respectively over the initial nutrient status of soil. Maize grain yield was also increased by 181.90 % (under application of 100% NPK+ vermicompost @ 5 t ha-1) over control. Combined use of vermicompost along with inorganic fertilizers were efficiently used by maize crop and had maximum values of yield attributes, yields as well as highest average net return of about Rs 57,716/ha and also maintained soil fertility.
