The right timing choice for rice depends on production system, but whether the rice is water-seeded, drill-seeded, or transplanted, early season N is critical for tiller development. However, applying too much N early is not advised because of the risk of losing the flood and much, if not all, of the early-applied N.
Deficit irrigation (DI) is a watering strategy that can be applied by different types of irrigation application methods. The correct application of DI requires thorough understanding of the yield response to water (crop sensitivity to drought stress) and of the economic impact of reductions in harvest.
