A field experiment was conducted during kharif  2007 at the Zonal Agricultural Research Station, Mudigere. Treatments consisted of organic sources viz., coffee pulp compost, rice hull ash and FYM combined with 50 or 100 per cent recommended fertilizers. The results revealed that application of  FYM @ 10 t ha-1 + rice hull ash @ 2 t ha-1 + 100% RDF recorded highest grain (6.24 t ha-1), straw yield (7.49 t ha-1), nutrient content (2.51% N, 0.61% P and 2.91% K) and nutrient uptake (170.66 N, 41.14 P and 209.76 K kg ha-1). It was followed by application of coffee pulp compost @ 2.5 t ha-1 + rice hull ash @ 2 t ha-1 + 100% RDF. After harvest of the crop, available nitrogen, phosphorus and potassium in soil were maximum in the above mentioned treatments. Based on economics, application of coffee pulp compost @ 5 t ha-1 + rice hull ash @ 2 t ha-1 + 50% RDF earned net returns of  Rs. 35,389 ha-1 followed by application of coffee pulp compost @ 2.5 t ha-1 + rice hull ash @ 2 t ha-1 + 100% RDF (Rs. 33,378 ha-1). They recorded highest benefit cost ratio of  2.73 and 2.48 respectively.
