Abstract: The field experiments were carried out during 2010-2012 in Kharif and summer seasons ( Kharif 2010, 2011 and 2012 and summer 2011 and 2012) in red loamy soil at Agricultural and Horticultural Research Station, Kathalagere, Channagiri taluk, Davanagere district of Karnataka, India to develop suitable integrated nutrient management practices for rice using organic and inorganic sources of nutrients through interaction of paddy straw treated with combination of cow dung slurry @ 5 % + Trichoderma harizianum @5 kg ha-1 + Pleurotus sajor caju @ 5 kg ha-1. The organic sources of nutrients used in the present study were FYM (Farm yard manure), paddy straw and Gliricidia sipium. The results of present investigation suggested that the application of 75 % NPK + 25 % NPK supplied through Paddy Straw treated with cow dung slurry @ 5 % + T. harizianum @5 kg ha-1 + P. sajor caju @ 5 kg ha-1 had improved soil chemical properties, which resulted in increased grain and straw yield with balanced combination of organic and inorganic source of nutrients.
