ABSTRACT

Field experiment was conducted during Kharif season of 2002 and 2003 to study the response of rice to INM practices in Mollisol. The yield attributes and yield in rice were studied with application of FYM @ 5 and 10 t ha-1, paper mill Bagasse @ 5 and 10 t ha-1 and inoculation with Blue green algae @ 10 kg ha-1 in a field experiment on a Typic Hapludolls. Application of FYM, Bagasse and BGA along with the recommended, 75 and 50 per cent of recommended fertilizer doses had positive effect on yield and yield attributing parameters over recommended fertility alone. Highest values were recorded in the treatment where 10 t FYM ha-1 was applied with recommended fertility levels and the average extent of increase in panicle (m-2), panicle length (cm), spikletets/panicle, 1000 grain weight and grain yield was 2.16, 5.34, 4.80, 1.81 and 9.0 per cent respectively.
