ABSTRACT

 

Both target species and soil microbial communities are affected by herbicides. These non-target outcomes may have an impact on the functioning of essential soil processes. In this context, the current experiment was conducted with the goal of determining the impact of weed management strategies on mustard soil enzyme activity. A field experiment was conducted on sandy loam soils during the 2020-21 rabi season. The study was duplicated three times and employed a randomized block design with twelve treatments. Standard statistical approaches were used to assess the data. Higher dehydrogenase activity was observed under oxadiargyl 6 % EC 0.09 kg ha-1 PE fb straw mulch 5 t ha-1(7.18 μg TPF g-1 soil day-1) and it was found to be on par with oxyfluorfen 23.5 % EC 0.1 kg ha-1 PE fb straw mulch 5 t ha-1, pendimethalin 30 % EC 1.0 kg ha-1 PE fb straw mulch 5 t ha-1. Similarly, urease activity, acid phosphatase activity and alkaline phosphatase activity were recorded higher with oxadiargyl 6 % EC 0.09 kg ha-1 PE fb straw mulch 5 t ha-1 (35.60 µg NH4-N g-1soil 2 hour-1) and it was on par with oxyfluorfen 23.5 % EC 0.1 kg ha-1 PE fb straw mulch 5 t ha-1.

Keywords   Acid phosphatase activity, Alkaline phosphatase, dehydrogenase activity, Urease activity.
