Allelochemicals may have concentration dependent influence on plant growth. At low concentration these chemicals promote the plant growth and may suppress the same when applied at higher concentration. This study was conducted to evaluate the growth promotery potential of sorghum, rice, maize and moringa water extracts. In the laboratory trials, application rate and frequency of sorghum, rice and maize water extracts (fresh and boiled) at different concentrations (100, 50, 25, 10, 5, and 3%) were evaluated and optimized for growth promotion of maize. Fresh and boiled extracts of sorghum, maize and rice were foliar applied alone and in combination with each other and along with moringa leaf extract (3%) at 30 and 50 days after sowing (DAS). Lower concentrations (3%) of sorghum, rice and maize plant water extracts promoted the seedling growth and seedling dry weights as compared to higher concentrations (25, 50 and 100%). In field experiments, combined application of fresh sorghum and moringa water extract (3%) increased the grain yield by 34-35% over control; whereas application of boiled plant extracts provided 35-38% improvement in grain yield over control from the combined application of boiled sorghum and maize water extracts at 3%. Moreover, marginal analysis of field experiments indicated that application of sorghum water extract (SWE) alone and combined application of rice and sorghum plant extracts had more marginal rate of return; nonetheless, application of fresh extracts had more marginal rate of return in this regard. In conclusion, application of allelopathic plant water extracts at lower concentrations (3%) alone and in combination improved the growth and productivity of maize. However, fresh water extracts alone or in combination may be preferred.

Populasi penelitian ini adalah seluruh pegawai badan layanan umum tahun 2020 yang berjumlah 765 orang. Metode penetapan sampel yang digunakan adalah purposive sampling. Sampel dalam penelitian ini sebanyak 75 responden. Data diolah dengan menggunakan analisis regresi linear berganda dengan bantuan SPSS Versi 25. Hasil penelitian menunjukkan bahwa semua variabel penelitian  berpengaruh dan signifikan terhadap kinerja Badan Layanan Umum.

Association Between Immediate Postnatal Anaemia and Risk of Developing Postpartum Depression at the Aga Khan University Hospital: A Cohort Study

Introduction: Postpartum depression has significant burden on obstetric psychopathology. While risk factors for the same have been extensively studied, most of this studies have focused on the role of psychosocial factors. Data on the role of physiological variables such as anaemia and role of obstetric complications in postpartum depression is now emerging. There are still gaps in literature regarding the same in developing countries and in Africa. Primary Objective: To determine the association between low postnatal hemoglobin andpostpartum depression Secondary Objective: To determine the association between obstetric complication specifically postpartum hemorrhage, operative delivery and NICU/NHDU admission and postpartum depression. Materials and methods: Study design: prospective cohort study Procedure: Using a cutoff of 11 grams/deciliter, 90 anemic and 90 non anemic women without a prior history of depression were recruited on the second postnatal day. The Edinburgh Postpartum Depression scale was administered at the six week postnatal visit and a score of 13 was used to determine those at risk of postpartum depression. Results: Using logistic regression analysis, we did not find a statistically significant association between postnatal anemia and postpartum depression. (Adjusted odds ratio 1.25, CI 0.51-3.05, p 0.6290). There was also no significant association between mode of delivery (OR 1.10 CI 0.46-2.60 p=0.8337) nor postpartum hemorrhage (OR 1.45 CI 0.60-3.54 p=0.4092) and postpartum depression. Admission to the neonatal unit (Adjusted OR 6.14 CI 1.09-34.42 p=0.039) and not taking antenatal iron supplements (Adjusted OR 2.83 CI 1.15-6.93 p=0.023) were significantly associated with postpartum depression. Conclusion: Postnatal anemia, postpartum hemorrhage and mode of delivery are not associated with postpartum depression. NICU/NHDU admission and not taking antenatal iron are associated with postpartum depression though this was not hypothesized a priori and may therefore be a chance finding. Recommendations: We recommend a prospective cohort study looking at the association of postnatal anemia, iron stores and postpartum depression. We also recommend a study looking at the association between adverse perinatal outcome (NICU/NHDU admission), operative delivery and postpartum depression.
