Effect of gypsum and phosphogypsum on the growth, yield and quality performances of rice

Abstract

Results obtained from a pot experiment suggest that gypsum and phospbogypsum at the rate of 0,15 and 3 0 n g S g - ‘ soil significantly increased the growth parameters (height, tiller numbers, panicle length) of BR-3 rice at maximum, panicle initiation and harvesting stages. Yield components (straw, grain, number of grains/panicle, weight/1000 grains and % filled grains) also improved significantly. Quality of straw and grain (content of N, P, K and S) improved significantly except S content in grain.
