The Effect of Two Biofertilizers under Two Crop Combination on Microbial Population and Early Plant Growth in Sandy Loam Soil (Published)
Biofertilizers are becoming increasingly popular in many countries and for many crops, but very few studies on their microbial population and early plant growth in sandy loam soil have been conducted. Therefore, this research evaluated two different biofertilizers: treated Ageratum spp. and Crotoloria spp. in the Soil Science Department Chukwuemeka Odumegwu Ojukwu University, Igbariam Anambra State, Nigeria during 2016 cropping seasons in the growth shelter of the Faculty of Agriculture, using two different test crops (Moringa and Tomato) which was laid out in complete randomized block (CRD). The experiments were conducted in pots with dimension of 17cm × 19cm in length and depth in which the bottoms were uniformly perforated for proper aeration. 10 seeds were planted after which 8 seedlings were thinned down 10 DAP, later, the remaining 2seedlings were harvested 60 DAP to evaluate the biomass production in each stage respectively. Significant biomass and soil microbial population increase due to biofertilizer use were observed in all experimental treatments. The biofertilizer effect on moringa and tomato growth did not significantly differ. Nevertheless, positive effects of the biofertilizers occurred on the biological properties. However, the trends in these results seem to indicate that biofertilizers might be most helpful in rainfed environments. However, for use in these target environments, biofertilizers need to be evaluated under conditions with abiotic stresses typical of such systems such as drought, soil acidity, or low soil fertility.
Evaluating the Effect of Moringa (K Formula Dietary Supplement) On Renal Function among HIV Positive Patients on TDF Regimen: A Longitudinal Study of Nigerians (Published)
This study evaluated the effect of Moringa on the renal function of HIV positive patients. It was a time dependent comparative pilot study involving 140 patients (53 (37.9 %) male and 87 (62.1%) female) in the sampled population, who attends ARV clinic at the University’s Teaching Hospital, Port Harcourt. The study was a 3 phases design to include Visit 0, 1 and 2 which lasted for about 12weeks (3months). The subjects were divided into two experimental groups (those receiving tenofovir and moringa and those receiving tenofovir without moringa supplementation). For the moringa group at visit 0, 1 and 2 respectively, the following values were obtained (Urine phosphate was 16.3711.84, 12.798.37 and 18.356.29; Urine Albumin was 2.001.41, 1.290.96 and 1.132.54; Urine Creatinine was 125.682.01, 418.53225.54 and 766.211030.82; Uric acid was 326.4387.45, 289.8782.50 and 239.3867.36; Urine Total Protein was 7.625.06; 19.8542.94 and 8.453.85. Significant differences were seen in the measured parameters at Visit 0, 1 and 2. However in the non moringa group, Urine phosphate was 16.93±12.53, 17.49±9.33 and 18.94±6.77; Urine Albumin was 0.90±0.56, 1.36±0.89, and 1.36±0.94; Urine Creatinine was 479±1.90, 489.06±445.09 and 514.85±595.55; Uric acid was 317.81±72.78, 311.79±65.55 and 259.56±84.04; Urine Total Protein was 15.04±26.73 9.50±5.07 and 6.53±3.84; for Visit 0, 1 and 2. Significant difference was observed in the measured parameters across all Visits from baseline to end of study. However differences were generally higher in the control, compared to the experimental groups. Finding therefore shows that moringa improved renal function slightly in HIV positive subjects, while sex was also observed to play a role. The study is therefore recommended to Physicians and care givers in other to help improve the health and wellbeing of HIV patients, especially those on tenofovir (TDF) based ARV regimen.
Moringa (Moringa Oleifera Lam.) Leaves Effect on Soil Ph and Garden Egg (Solanum Aethiopicum L.) Yield in Two Nigeria Agro-Ecologies (Published)
Soil acidity is a major constraint in soil fertility maintenance, particularly, in the humid tropics. Sustainable production of crops on acidic soils depends on soil amendment to remediate acidity and fertility status. The objective of this research was to investigate the effects of incorporating Moringa leaves on soil acidity amelioration and garden egg yield. The field trials were conducted at the Teaching and Research Farms of the University of Agriculture, Makurdi, and the Faculty of Agriculture, Cross River University of Technology, Obubra in 2009 and 2010. Treatments consisted of two varieties of garden egg (Gilo and Kumba) and four rates of Moringa leaves. Fresh Moringa leaves were applied at the rates of 0, 5, 10 and 20 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. The results obtained showed that all rates of the manure reduced the soil pH within 30 days after incorporation in both years and locations. At 60 days after application, and up to 140 days after incorporation, all manure rates increased the pH in both locations and years. The control, however, showed a steady pH decrease up to 140 days after incorporation. All manural rates significantly (P<0.05) increased the yield of the garden egg varieties over the control. Moringa at 20 t ha-1 produced the highest fruit yield in both years and locations. The crop yields were significantly higher in Makurdi than Obubra in both years and the yield for 2010 was significantly higher than for 2009 in both locations. Moringa leaves, at the rate of 20 t ha-1, are a promising soil amendment for the remediation of soil acidity and this rate is recommended for the sustainable production of garden egg
