Rice Cultivation in Alkali Soils
• Addition of Gypsum: If the pH of soil is more then 9.3 then apply gypsum on soil test
basis and give one or two heavy irrigations.
• Preparation of Seed bed: Do not puddle, because water intake rate in these soils is
very low. Irrigate the tilled field and give a light planking to pulverize the clods.
• Transplanting: Transplant seedlings a week earlier than the normal time of
transplanting, because the initial growth of plants in alkali soils is slow. Plant three or
four 40 days old seedlings per hill. More seedlings per hill are recommended because
of higher mortality in these soils. Do not grow PR 127 under alkali conditions
