Effect of biofertilizers on yield and seed quality parameters in cotton

Abstract

Cotton cv. MCU 9 grown in the 1986-87 kharif [monsoon] seasons was seed and soil inoculated with Azospirillum or Azotobacter, and/or given different rates of N fertilizer. Yield was not increased by inoculation alone. Yield was similar in crops given 80 kg N/ha, Azospirillum + 40 or 60 kg N/ha, or Azotobacter + 60 kg N/ha. Viability of harvested seeds was not affected by treatment.
