Investigations on the rôle of silicon in plant nutrition. Part IV. Effect of silicate fertilisation on the growth of the rice plant and yield of paddy

Abstract

Observations have been made on the growth of the rice plant and yield of paddy under arid and flooded conditions with and without addition of organic (green) manure, sodium silicate and potassium phosphate respectively. It is found that treatment with sodium silicate increases the yield of grain and straw and that both in unmanured and manured soils the response is greater in arid than in flooded series.
