Abstract

Burning, plowing or removing straw from the fields with eight successively planted rice crops did not significantly affect rice yields, N content of the straw or grain, recovery of fertilizer N or organic matter content of the soil. Yields increased with N applications up to over 100 kg/ha. N contents of the straw and grain also increased irrespective of method of straw disposal. Nitrogen applications did not affect N or organic matter content of the soil.
