Effects of Seed Coating With Sodium Humate and Biofertilization on Growth and Yield of Bean and Wheat

Abstract

Plants grown from seed coated with sodium humate and inoculated by certain biofertilizers bacteria, were investigated under greenhouse conditions. The nodulation status, nitrogen uptake and yield component of bean Phaseolus vulgaris , inoculated by specific rhizobia increased by application with sodium humate. The application of sodium humate alone without rhizobial inoculation had good growth stimulating effect. A fair increase in the yield and phosphorus uptake of wheat Triticum aestivum inoculated with Azotobacter and/or Bacillus spp. was also recorded with the addition of the humic material. The greatest effect was observed on the plants inoculated with Azotobacter and Bacillus spp. together.
