Abstract
The effect of various concentrations of foliar application of resorcinol on chlorophyll contents, shoot ischolar_main dry matter production and yield (pod size and weight per 100 seed) were studied in soybean. Chlorophyll contents and shoot ischolar_main dry matter production were found to decreased at all the growth stages whereas, pod size and weight per 100 seed and pod size found to increased maximum at R2 stage with 1000 ppm resorcinol application. Higher concentrations of resorcinol at R2 stage were also detrimental. At R2 stage leaves have maximum assimilates and foliar application of lower concentration of resorcinol helps in remobilization of assimilates from vegetative part to reproductive part, which result in improved yield. It can be concluded that resorcinol can be used as partitioning agent to improve the productivity when it is used at appropriate growth stage with its optimum concentration.
