soil microbes play critical roles in soil biogeochemistry, soil biological health and crop productivity. The current study evaluated the effects of tillage and residue management on changes in soil biochemical indicators at different growth stages of wheat after 5 years of rice-wheat system. Nine treatment combinations of tillage, crop establishment and crop residue management included three main plot treatments applied to rice:(1) conventional till direct dry seeded rice(CTDsr),(2) zero till direct dry seeded rice(ZTDsr), and(3) conventional puddled manual transplanted rice(CTPTr) and three subplot treatments in subsequent wheat:(1) conventional tillage with rice residue removed(CTW-r),(2) zero tillage with rice residue removed(ZTW-r) and(3) zero tillage with rice residue retained as surface mulch(ZTW+r). Irrespective of rice treatments, ZTW+r treatment had higher soil biochemical indicators compared with ZTW-r and CTW-r at all the growth stages of wheat. Generally, all the biochemical indicators were the highest at the flowering stage of wheat. residual effect of rice treatments was also significant on biochemical quotients in wheat, which were the highest under ZTDsr followed by CTDsr and CTPTr. The present study provided three sensitive and reliable biochemical indicators(microbial biomass, basal soil respiration and microbial quotient) which respond rapidly to change in tillage and residue management practices in rWs of south Asia.

Objective: To evaluate the effects of Oscimum sanctum l(O. sanctum), an important medicinal herb, on alcohol withdrawal syndrome in Wistar rats. Methods: liquid diet with 7.2%, v/v ethanol was administered to the rats for 21 d. Control group animals received sucrose as an isocaloric liquid diet. After alcohol withdrawal, rats were examined at 6 th and 24 th hour for major withdrawal signs that included anxiety and hyper locomotor activity. Ethanol withdrawal anxiety was tested using elevated plus maze, light and dark model; the hyper locomotor activity using actophotometer. O. sanctum leaf extract(100, 200 and 300 mg/kg, oral) and diazepam(2 mg/kg, i.p) were administered to the treatment group animals 30 min before alcohol withdrawal estimation. Drug treatment was also given 30 min before the second observation at 24 th hour. On the last day of the protocol, rats were sacrificed by cervical dislocation liver, kidney and brain were isolated and preserved in formalin for further histopathological examination. results: Findings from the present study revealed that O. sanctum leaf extract treatment at doses 100, 200 and 300 mg/kg, oral had a significant protective effect on signs and symptoms of ethanol withdrawal in alcohol-dependent rats. However, no remarkable pathological and microscopic alterations were observed in histopathological examination. Conclusions: O. sanctum seems to be an active drug for the treatment of alcohol abstinence syndrome.
