A field experiment was conducted to study the effect of plant growth promoters on assimilate partitioning and seed yield of green gram during summer 2002. The results revealed that foliar application of putrescine and spermine @ 20 ppm registered higher growth characters (plant height, number of trifoliate leaves plant−1, leaf area index and dry matter production). Yield attributing characters such as number of flowers plant−1, number of pods plant−1, fertility coefficient, number of filled seeds pod−1 and per cent filled seeds were also increased. Application of putrescine and spermine had increased per cent seed weight and reduced the seed coat dry matter accumulation. It also registered significantly increased partitioning of assimilates in economic parts from leaf, stem and root. Putrescine and spermine recorded an additional yield of 42 and 39 per cent respectively over control by maintaining better partitioning assimilates.
