A field experiment was conducted for two consecutive years from rabi seasons of 2013-14 and 2014-15 to kharif seasons of 2014 and 2015 at Research Farm Chatha, Division of Agronomy, Sher-e-Kashmir University of Agricultural Sciences and Technology, Jammu to assess the dynamics of the soil microbes in wheat (Triticum aestivum L.) – direct seeded basmati rice (Oryza sativa L.) crop sequence under the influence of different weed management interventions. The results of the study reveals that soil microbial count with regard to bacteria, fungi and actinomycetes on the experimental site at 15 and 30 days after the imposition of the treatment registered significant reduction in the soil microbial population in herbicide treated plots over weedy check and mechanical weedings (at 30 and 60 DAS). However, slight increase in the counts of soil micro-organisms were observed at 30 days after the application of herbicides in comparison to their initial counts that were recorded 15 days after the imposition of herbicide treatments. The results imply a recovery in the soil microbial population after initial reduction following the use of herbicides at recommended rates. Consequently no deleterious effects on soil biological health and crop yields were noticed. Instead, the application of herbicides reduced the weed menace to a greater extent resulting in higher crop yields.
