The influence of urban compost on yield of sesame is not fully known. In this context, a study was conducted to investigate the effect of varying rates of urban compost in combination with recommended dosage of fertilizers (RDF) on yield of sesame variety, Swetha til. Field experiments were carried out for three years during rabi 2012-2015. The experiments were laid out in randomized block design with three replications. 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 (40:40:20 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. Seed yield, stalk yield, total dry matter yield and harvest index were determined. Pooled data analysis results revealed that the beneficial effects of application of urban compost were enhanced up to 5 t ha-1 and then decreased with increasing rates of application. The performance of sesame was superior on the field fertilized with RDF plus 5 t ha−1 urban compost from Jawahar nagar which was comparable to RDF plus 5 t ha−1 urban compost from Autonagar. Application of 5 t ha-1 of urban compost from Jawahar nagar along with RDF recorded highest seed yield (559 kg ha-1), total dry matter yield (1,909 kg ha-1) and harvest index (29.73 %). Thus, the combined use of urban compost and chemical fertilizers may be suitable for improving sesame performance.
