A field experiment was conducted during summer season of 2015-16 to study the effect of time of sowing, spacing between plants and fertilizer levels of green gram (Vigna radiata (L.) Wilczek) on seed yield attributing characters. Five levels of fertilizer doses, three different time of sowing and three spacing levels were imposed along with control under split plot design with three replications. Field data were recorded on pods per plant, number of seeds per pod, seed yield per plant, seed yield per ha. and 1000 seed weight were recorded. Analysis revealed that all the characters are significantly different among the treatments. Early sowing during summer i.e on march 20 th with the spacing of 25 X 10 cm recorded higher pods per plant ( 18.40 ), number of seeds per pod ( 13.08 ), seed yield per plant ( 6.9 gm ), seed yield per ha.( 8.9 q.) and 1000 seed weight ( 39 gm ). Late sowing of green gram during April 10 th recorded lowest in all the characters. Seed treatment with Rhizobium and Phosphate Solubilising Bacteria + 150 % RDF as basal + Borax spray ( 100 ppm ) at flower initiation recorded significantly highest in pods per plant (19.9 ), number of seeds per pod ( 14.06 ), seed yield per plant ( 8.5 gm ) and seed yield per ha.( 10.6 q ). Early sowing with march 20 th with the spacing of 25 x 10 cm and Seed treatment with Rhizobium and Phosphate Solubilising Bacteria + 150 % RDF as basal + Borax spray ( 100 ppm ) at flower initiation is recorded best among all the treatment combinations for achieving higher seed yield.
