Pinto bean (Phaseolus vulgaris) is being sown in Iran from April to July. To investigate the effect of acetylsalicylic acid (ASA) and Bacillus velezensis bacteria on pinto bean yield and yield component, an experiment was conducted as a split-split plots experiment in a randomized complete block design with four replicates in the research farm of the college of Agriculture and Natural Resources, University of Tehran in 2021 on separate planting dates (mid May and late June). The treatments included two irrigation levels (irrigation 70% and 100% of the plant's water requirement) as the main plot, foliar spraying (ASA hormone at 0.5 mM level and control) as a secondary plot and inoculation with Bacillus velezensis bacteria and no inoculation as a secondary subplot. Results of the analysis of variance showed that the interactions of sowing date, irrigation, foliar spraying, and inoculation with bacteria on the traits measured in pinto beans was significant. The maximum plant height (154 cm), number of sub-branches (7), leaf area index (7.3), seed yield (3045 kg/ha), and harvest index (43%), 100 seed weight (37 g), pod number (24) were obtained in mid-May planting date, along with salicylic acid foliar spraying and bacterial inoculation without water stress. The highest biological yield (7997 kg/ha) was obtained under water deficit stress (70% of plant water requirement) and foliar spraying with ASA hormone and inoculation with bacteria, in late June sowing date. Overall, hormone spraying and inoculation with bacteria improved the yield characteristics of pinto bean under drought-stress conditions in both sowing dates.

Determining the clinical manifestations of COVID-19 in pregnant and recently pregnant women is important to identify risk factors in order to evaluate complications and maternal and perinatal outcomes. The aim of the present study was to investigate the symptoms of COVID-19 in pregnant women and its effects on the newborn.

The Now study was a prospective descriptive study. This research was conducted in 2020 on 101 pregnant women with COVID-19 infection admitted to the intensive care unit in Zabol city, Iran. All studied patients were examined in terms of clinical symptoms, maternal and neonatal complications, and laboratory findings such as WBC and ESR in all patients were checked. Finally, all information was entered into each patient's form and by using SPSS V22 software analyzed.

Number of 101 pregnant women participated in the study, with an average age of 31.09 years. In this study, 93 individuals had PCR positive (92.1%), 84 individuals with COVID+ in CT scan (83.2%), 25 individuals with an underlying disease (24.8%), and 54 individuals with addiction (53.5%). 20 feet (19.8%) were reported. 20 deaths (19.8%) were reported. The average BMI of the participants was 25.46. Among maternal complications, pulmonary involvement (71.28%) the most frequently was reported. Among the hospitalized patients (95 individuals), 25 individuals had underlying diseases. In this population, maternal complications were significantly more reported (P value=0.012). Among neonatal complications, the most common cases of death were IUFD and abortion. 62.1% of the participants had a natural delivery and 63.4% had a term delivery.

Fever, throat redness and swelling, respiratory distress and cough are the most common clinical symptoms and lung involvement is the most common complication of COVID infection in pregnant mothers. In infants, IUFD and abortion were also very common. PCR and CT scan are two high-sensitivity tests for detecting COVID.
