An investigation was carried out to study the effect of distillery effluent based pressmud compost (DEPC) on seed yield and seed quality attributes of paddy cv. Pus a Basmati-1 at Seed Production Unit, lARI, New Delhi. The treatments consisted of 1.5 tonnes DEPC (T -1), 1.5 tonnes DEPC + 50% NPK (T -2), 3 tonnes DE PC (T-3), 3 tonnes DEPC + 25% NPK (T-4), 6 tonnes DEPC (T-5) and recommend dose of NPK/ha (T-6) and were laid out in four replications in a randomized block design (RBD). The observations on seed yield and seed quality attributes, viz. number of total tillers/hill, number of productive tillers/hill, days to 50% flowering, plant height (em), panicle length (em), number of grains/ panicle, filled grains/panicle, grain yield, harvest index, 1000 seed weight, germination, seedling length, seedling dry weight and vigour index were recorded. The data recorded during kharif 2000-2001 and 2001-2002 were pooled and subjected to statistical analysis. The significantly higher seed yield of 51.65 q/ha was recorded in T-4 followed by T-6 (51.08 q/ha) and T-5 (49.29q/ha). The seed quality attributes were also significantly higher for 1000-seed weight (21.04 g), seed germination (81%), seedling length (22.8 em), and vigor index (1847) were recorded in T-4 (3 t/ha distillery effluent pressmud compost + 25% recommended dose of fertilizer) followed by T-6 (100% of recommended dose of fertilizer) and T-5 (DEPC + 25% NPK) respectively. To obtained higher seed yield (51.65 q/ha), an application of 3 t/ha distillery effluent pressmud compost + 25% recommended dose of fertilizer is recommended
