Influence of urea, organic manures, Azospirillum and growth regulators on the yield of rice

摘要

The effect of combined application of urea, farmyard manure, green manure, Azospirillum and growth regulators (cytozyme and triacontanol) on the yield of rice was studied. Increasing levels of the fertilizer N and Its combination with organic sources,application of cytozyme or triacontanol or pretreatment of seed with Azospirillum increased the growth and yield of rice. Combining the fertilizer N with other sources of N significantly reduced the sterility and increased the yield of rice.
