Effects of Manurial Treatments and Times of Planting on Rice Production in Different Soil Types in West Bengal1

  1. M. N. Basak and
  2. A. W. Klemme2



Thirty pounds of N per acre caused a significant increase in yield. Responses to bulky organic manure and ammonium sulphate, alone or in combination, were practically identical. Lateritic soils showed a higher grain-producing capability than low-land Gangetic alluvium soils of higher fertility status. Yields of grain decreased progressively with delay of planting from mid-July to mid-September. Time of application of ammonium sulphate had no influence on rice yield. Split applications were moderately superior to composite applications.
