Abstract: Field experiments were conducted to study the influence of varying rates of urban compost in combination with recommended dosage of fertilizers (RDF) on yield and water productivity of green gram variety, LGG – 460. 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 (5.0 t ha-1), three rates of urban compost from Jawahar nagar (1.25, 2.5 and 5 t ha−1) + RDF and three rates of urban compost from Autonagar (1.25, 2.5 and 5  t ha−1) + RDF. Seed yield, Bhusa yield, total dry matter yield, harvest index and water productivity were determined. Perusal of pooled data indicated that the crop applied with urban compost from Autonagar (Urban Compost–II) @ 5.0 t ha-1 along with RDF of 20:50:0 N, P2O5 and K2O kg ha-1 recorded significantly higher seed yield of 386.3 kg ha-1 and were on par with the urban compost from Jawaharnagar (Urban Compost –I) @ 5.0 t ha-1 along with RDF. Significantly lower yield of 256.7 kg ha-1 was recorded with crop received RDF of 20:50:0 N, P2O5 and K2O kg ha-1 and was on par with application of FYM 5t ha-1 and urban compost of both sources @ 1.25 t ha-1. Therefore, application of urban compost @ 5 t ha-1 with 100 % of the recommended dose of NPK fertilizers can be practiced for profitable green gram production.
