Abstract

A laboratory experiment was conducted with two new generation herbicide pyrazosulfuron ethyl treatments, namely, recommended dose 15 g a.i. ha-1 (RD) and 30 g a.i. h-1 (2RD), carfentrazone ethyl 25 g a.i ha-1(RD), 50 g a.i. ha-1 (2RD) along with control (without herbicide) applied to sandy loam soil to determine their effect on microbial biomass dynamics in soil. The application of pyrazosulfuron ethyl (T1 and T2) and carfentrazone ethyl (T3 and T4) did not show any significant effect at 0 day after application. While, at 7 days after application of herbicide declined soil microbial biomass status. Whereas, at 28 days after application significantly increasement microbial biomass carbon and microbial biomass nitrogen except for microbial biomass phosphorus under herbicidal treatments compared to untreated plot. Hence, pyrazosulfuron and carfentrazone ethyl may cause short term transitory change in microbial biomass dynamics in soil moreover at 28 day after application of herbicide no any harmful effect at recommended dose of pyrazosulfuron ethyl and carfentrazone ethyl.

Keywords: Microbial biomass carbon, nitrogen, phosphorus, herbicide
