Foliar application of a phosphonic acid plant growth regulator to rice crop plants, when the plants are at a growth stage of between about the start of tillering and initiation of panicle primordia, at about 50 to about 750 grams per hectare, results in rice yield significantly greater than untreated rice crops. The invention promotes manipulation of certain physiological processes at vegetative growth stages, thereby reducing decline in tiller number and increasing the number of seed producing tillers. |
