摘 要：Sustainable vegetable production especially during the dry season requires adequate conservation of soil *** study was conducted to evaluate the sole and interactive effects of mulching(M)and poultry manure(PM)application on soil temperature(ST),crop evapotranspiration(ETc)and water use efficiency(WUE)of *** experiment was a Randomized Complete Block Design(RCBD)with three *** treatments were M at 0 and 6t ha^(-1)and PM at 0,10 and 20t ha^(-1).Soil temperature was measured using digital thermometer while ETc was determined by water depletion method using a Time Domain *** at field capacity was applied manually at 2-day *** appli-cation of mulch significantly lowered ST while joint application of 20t ha^(-1)PM(PM20)and M signifi-cantly(p≤0.05)reduced ST at 5 cm and 10 cm soil depth compared with the unmulched plots in both *** of 10t ha^(-1)PM(PM10)without M recorded the highest ETc(43.7 mm),while joint application of PM20 and M reduced ETc by about 93%compared with PM10 *** used water most efficiently when PM20 was applied under mulched *** was 62.2%increase in WUE under mulched plots compared with the control while the residual effect of PM10 and M significantly increased WUE by 65.5%.It was evident that M alongside application of PM is a good strategy for regulating ST,moderating ETc and increasing okra WUE,especially during dry season farming.
