Nutrient concentration in stem
The incorporation of rice straw into the soil alone and combined with various organic fertilizers had a significant effect on the N, P and K concentration of stem. The incorporation of rice straw into the soil combined with the application of cattle manure and bio-extracted fertilizer gave maximum N (0.535%) concentration of the stem. The incorporation of rice straw into the soil combined with application of cattle manure obtained the maximum P (0.267%) and K (2.938%) concentration of
the stem
