Abstract Owing to their nutritional and health benefits, the cultivation of Pleurotus species continues to receive global attention. This study aims at determining the growth, yield and nutritional quality of Pleurotus pulmonarius and Pleurotus ostreatus. In this study, 10g of P. pulmonarius and P. ostreatus each were cultivated on 400g of sugarcane bagasse and cotton waste individually. Each substrate was supplemented with wheat bran separately at varying compositions (0%, 5%, 10%, 15% and 20% w/w) in triplicates and incubated at 28±20C for 35days.The experiment was arranged in Complete Randomized Design. Data were subjected to analysis of variance (ANOVA) while the means were separated with Duncan Multiple Range Test at P?0.05. After the incubation period, the growth and yield of mushroom were assessed. P. ostreatus cultivated on sugarcane bagasse with 15% wheat bran additives had the highest stipe length, stipe width and pileus width ranging from 3.93-4.07cm ,3.23-4.77 and 5.03-6.43 respectively at flush 2 and 3 respectively. Also, P.pulmonarius had best the stipe width (5.17cm) performance on cotton waste with 10% wheat bran at flush 2 while P.ostreatus had the highest stipe length of 4.17cm on cotton waste with 10% wheat bran at flush 3.The total biological efficiency of P.ostreatus was highest at 15% wheat bran grown on sugar bagasse with 13.59g and 3.40% respectively. On sugarcane bagasse, P. pulmonarius cultivated on 10% wheat bran had the highest dry weight with 0.87g, 0.80g and 3.67g respectively for flush 1 and 3 while P. pulmonarius cultivated on cotton waste with 10% wheat bran had the highest dry matter (3.85g) but greatly rich in potassium (1.32-6.82%). The protein contents range from 26.60-30.46%. The highest carbohydrate was recorded in P. pulmonarius with 10% additive in sugarcane bagasse while P. ostreatus grown in 10% cotton waste recorded the highest carbohydrate content. P. pulmonarius cultivated on sugarcane bagasse with wheat bran additives, irrespective of their percentage concentration, had better mushroom quality/size, yields, biological efficiency, mineral composition and proximate composition than P. ostreatus. This study will guide the mushroom farmers in the selection of mushroom species, substrates and additives for healthy and vigorous mushrooms. Key words: Pleurotus ostreatus, P. pulmonarius, cotton wastes, sugarcane bagasse, proximate composition.

Abstract Medicinal plant extracts have been used in different cultures, for treating ailments and managing health issues like
inflammatory conditions, hypertension, diabetes mellitus, arthritis, epilepsy, etc. Extracts of mistletoe leaves were
studied for their mineral, nutritional and phytochemical composition. The proximate analysis results reveal high
fibre content (11.1%) and low fat (3.2%) content, making it a good cholesterol-lowering agent. The mineral
composition revealed that mistletoe leaves are nutritionally beneficial as they contain relatively high levels of
iron, calcium, potassium, manganese and magnesium, which all play important physiological and metabolic roles
in the body. The Na/K and Ca/P ratios of 0.623 and 3.931 respectively are considered favourable, making the
leaves nutritionally and physiologically important. The presence of tannins, saponins, flavonoids, steroids, resins
and alkaloids could be responsible for their use in traditional medicine. These findings therefore reveal that
mistletoe leaves can be utilized as medicinal/curative agents in ameliorating health-related issues such as
hypertension, cancer, arthritis and fertility-related ailments; as well as being nutritionally beneficial, if properly
harnessed.

Abstract This study examines the efficiency of 17-day stored human urine as an organic manure to improve the
growth and productivity of Talinum triangulare in Alihame Community, Nigeria. Given the economic
hardships faced by local farmers and declining soil fertility, this research aimed to determine if stored
human urine could be a viable alternative to replenish infertile soil. Experimental pots were treated
with two different concentrations of human urine (360.10 mL and 620.10 mL) and compared against a
control (0 mL). Key growth parameters were plant height, number of leaves, number of branches, and
stem girth were measured at 11, 18, 25, and 30 days while chlorophyll content, leaf relative water
content, and fresh weight of leaves, shoots, and roots were measured at 30 days. The results revealed
significant improvements in all parameters with urine treatments compared to the control. Talinum
triangulare treated with 620.10 mL of urine exhibited the highest growth metrics across all parameters.
This study demonstrates that 17-days stored human urine can be as effective as organic manure in
improving plant growth and productivity, suggesting its potential for sustainable agricultural practices.
