The present research was conducted with an objective to study the influence of varying rates of urban compost in combination with recommended dosage of fertilizers (RDF) on yield and yield components of rice variety, BPT 5204. Field experiments were carried out for three years during rabi 2012-2015. The experiment was laid out in a randomized complete block design with three replicates. The urban compost was procured from two different dumping yard sources of Hyderabad. One is from Jawahar nagar dumping yard, which was established during 2002 and the second source is Autonagar, which is a more than 50 years old dumping yard. There were eight treatments comprising recommended dose of N,P,K (120:60:40 N, P2O5 and K2O kg ha-1), RDF + Farm Yard Manure (10 t ha-1), three rates of urban compost from Jawahar nagar (2.5, 5 and 10?t ha?1) + RDF and three rates of urban compost from Autonagar (2.5, 5 and 10?t•ha?1) + RDF. Grain yield, straw yield, total dry matter yield, harvest index and water productivity were determined. Pooled data analysis results revealed that the beneficial effects of application of urban compost were enhanced at increased rates of application. The performance of rice was superior on the field fertilized with RDF plus 10?t ha?1 urban compost from Jawahar nagar which was comparable to RDF plus 10?t ha?1 urban compost from Autonagar. The highest grain yield (6,095 kg ha-1), straw yield (9926 kg ha-1), total dry matter yield (16021 kg ha-1), harvest index (37.63 %) and water productivity (7.73 kg ha-1) were recorded in plots applied with RDF + 10?t ha?1 urban compost from Jawahar nagar. Therefore, it is evident that yield of rice can be increased significantly with the combined use of urban compost and chemical fertilizers.
