ation. However, their residues persisted for more than 30 days with variable half-lives ranged from 2.6 to 30 days. The toxicological study revealed that metabolites C, E and F were highly pernicious to soil enzymes sucrase, catalase, urease and dehydrogenase. PYR do not posed any detrimental effects in adult honeybees. Considering the persistence behavior and toxicological consequences of metabolites, further investigations are needed for preventing their harmful effect on non-target organisms and associated environment.

The activity of dehydrogenase (µg TPF produced g-1 day-1 ) followed decreasing trend from before treatment imposition to 3 days after treatment imposition thereafter it showed increasing trend. Sulfonyl urea herbicides had the lower dehydrogenase activity immediately after herbicide application as compared to the other herbicide group’s viz., chloroacetamide, triazolepyramidine, pyramidinethiobenzole and aryloxyphenoxy propionate. Urease activity (g of NH4 + released g-1 soil 2 hr-1 ), increased from 0 DAT up to 45 DAT and thereafter it decreased.

The microbial and enzyme activities of the soil are closely related to the organic matter content and influenced by hydrothermal regimes of the soil. Keeping this in view, the study conducted that effect of different cropping systems on dehydrogenase, urease, acid and alkaline phosphatase activity and microbial population like bacteria, fungi and actinimycetes was evaluated from ˃ 20 year old cultivation under different cropping systems i.e., mango, cashew, vegetable, rose and medicinal and aromatic crops at different depths (0-15, 15- 30, 30-50. 50-100 cm).

The rice-wheat cropping system, which is considered as the backbone of food selfsufficiency, is facing a sustainability problem due to practices of modern production system with indiscriminate use of chemical fertilizers and pesticides. So, effects of long term use of mineral fertilizers and farmyard manure (FYM) under rice (Oryza sativa)– wheat (Triticum aestivum) cropping system in a Mollisol was investigated. Rice and wheat yields were highest (51.47 and 48.60 q ha-1 , respectively) with 100% NPK + 15 t FYM ha−1 and lowest in control (13.72 and 11.85 q ha-1 , respectively).

Soil biochemical properties are indicators of soil quality, but there is still no consensus as to how they should be used. Generally, biochemical properties related to the biocycles of the elements (C, N, P and S) are used to diagnose soil quality. These properties include both general biochemical parameters (i.e. microbial biomass C, dehydrogenase activity and N mineralization potential) and specific biochemical parameters (i.e. the activity of hydrolytic enzymes, such as phosphatase, Dehydrogenase, urease and b-glucosidase).
