A field experiment was conducted during Kharif 2017 and 2018 at three villages Lemberdung, Khinmey and Changprong in Tawang district of Arunachal Pradesh to study the effect of combination of organic nutrient sources for maize production. The experiment consisted of eleven treatments, comprising different levels of compost manure equivalent (75, 100 and 125kg N/ha) with FYM @ 10 t/ha, beejamrith + Jeevamrith. The results indicated that, application of 100% N equivalent compost + FYM @ 10 t/ha +beejamrith +jeevamrith @ 500l/ha. recorded significantly higher grain yield (5.3 t/ha), cob length (14.5 cm) and plant height (225.5 cm), which was closely followed by application of 100% N equivalent compost +beejamrith + jeevamrith @ 500 l/ha and 125% N equivalent compost +beejamrith + jeevamrith @ 500 l/ha. Soil chemical properties, viz., soil pH, organic carbon and electric conductivity were not influenced by application of organic manures. However, an increasing trend was observed in the soil chemical properties selative to initial soil data. Application of 100% N equivalent compost + FYM @ 10 t/ha + beejamrith + jeevamrith recorded significantly higher available nitrogen, phosphorous and potassium content in the soil compared to the other treatment.
