Sustainable vegetable production especially during the dry season requires adequate conservation of soil water.This 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 okra.The experiment was a Randomized Complete Block Design(RCBD)with three replicates.The 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 Reflectometer.Irrigation at field capacity was applied manually at 2-day intervals.Independent 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 seasons.Application 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 only.Okra used water most efficiently when PM20 was applied under mulched plot.There 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.

Malaria and COVID-19, though caused by different organisms, share a significant number of symptoms like fever, headaches, difficulty in breathing and fatigue. Therefore, determining if a patient is positive for COVID-19 or Malaria based on symptoms alone, might be misleading, especially during pandemic response. It has been reported that an individual begins to manifest Malaria symptoms between 10 - 15 days after infection with malaria parasite, although some individuals may be asymptomatic. Some COVID-19 infected patients, like Malaria, are also asymptomatic but could contribute to transmission of SARS-CoV-2 virus. These similarities in symptoms have led to misconception about COVID-19 being real and misdiagnoses of both infections, especially in Nigeria. However, there are possibilities that Malaria and COVID-19 could co-exist in some individuals thereby leading to mismanagement and treatment of only one infection while neglecting the possibility of the patient being infected with both diseases. We aim to determine possible correlation between Malaria and COVID-19 in a Malaria endemic country like Nigeria. This study was carried out using the qPCR molecular testing approach, a gold standard for COVID-19 testing and rapid diagnostic test kits to detect Malaria parasites in 617 individuals residing in urban settings. We demonstrated that COVID-19 and Malaria infection amongst adults in urban settings are unrelated thereby focusing on symptoms alone may result in misdiagnosis. Our findings show that Malaria is not among the underlying medical conditions strongly associated with increased risk for severe COVID-19 illness amongst adults in urban settings.
