ABSTRACT

 

In order to find comparison of effect of biofertilizer treatments on seedling growth and available nutrients in soil of variety RT-54, JLT-7 and GT-1 of Sesamum indicum L. were analysed. In comparison to treatments, root length of variety RT-54 and GT-1 affected by Azotobacter and PSB, while root length of variety JLT-7 affected by Azotobacter and Azotobacter with PSB. Shoot length of variety RT-54 and JLT-7 significantly affected by Azotobacter, while in variety GT-1, shoot length significantly influenced by PSB and Azotobacter with PSB. All three treatments of biofertilizer significantly and equally affected soil organic carbon of variety RT-54, in variety JLT-7, PSB most significantly increased soil organic carbon, while in variety GT-1, Azotobacter and Azotobacter with PSB influenced it. Available nitrogen and phosphorou in soil of variety RT-54 significantly increased in Azotobacter and Azotobacter with PSB, while in variety JLT-7 and GT-1 both soil contents significantly increased in Azotobacter and Azotobacter with PSB treatment respectively. Variety GT-1, showed highest root length, shoot length, available nitrogen and phosphorous. Available potassium in soil of variety RT-54 and GT-1 not significantly influenced by biofertilizer treatments. However, potassium content in soil of variety JLT-7, most significantly affected by Azotobacter. Variety JLT-7, showed highest organic carbon and available potassium under treatment of PSB and Azotobacter respectively. Root length, shoot length and available nitrogen of variety RT-54 and GT-1 higher in 2005 while in JLT-7 it was higher in 2006. In all three varieties soil organic carbon and available potassium higher in 2005 while available phosphorous was higher in 2006.
