“…Sawdust and grasses could have been supplemented the nutrient requirement of the soil. This observation was in line with the report of Ikeh and Akpan (2018) and Ikeorgu et al (2006) that organic mulching is source of organic manure to soil. Udoh and Ndon (2016) also revealed that organic mulching is not only to check evaporation but also help to add organic matter to the soil.…”

“…The low weed density and biomass observed in mulched plots compared to the control plots could be that organic and inorganic mulching materials were able to shade and smother some weeds. This agrees with the findings at Ikeorgu et al (2006) who reported that covering the soils with cover crops, straws, grasses or even synthetic materials could effectively suppress weeds growth and prevents them from receiving sun light.

The experiment was carried out at Umulolo in Okigwe Imo State in 2016 and 2017 seasons. The experiment was laid in randomized complete block design, replicated three times. The treatments were mulching materials (two synthetic materials-polythene sheet, trampoline sheet) while natural or organic materials were 6/ha sawdust and grasses and control treatment (no mulching). Result showed significant difference in all the weed infestation parameters, vegetative growth and yield parameters assessed. In both cropping seasons, the control had significant higher weed density and biomass. Garden egg fruit yield as influenced by different mulching materials was also significantly different (p<0.05) in both cropping seasons. The highest fruit yield; 22.27 and 23.63 t/ha in 2016 and 2017, respectively was from the plot mulched with sawdust. The grasses mulched plot had 21.19 and 22.17 t/ha fruit yield, respectively. The trampoline plot produced 18.77 and 17.18 t/ha fruit, respectively. The least fruit yield was 5.43 and 6.54 t/ha in both cropping seasons in control treatment. The result showed that the plot mulched with sawdust had 7-76% and 6-72% greater fruit yield compared to the other mulching materials in both cropping seasons. The result of indicated that application of grasses and sawdust were more cost effective in weed management and higher economic returns to management compared to trampoline and polythene sheets. Farmers in the study area were advised to mulch their garden egg field during off-season with sawdust. The application of sawdust would reduce weed infestation and also enhances high fruit yield.

One of the most important factors in strawberry (Fragaria × ananassa) cv. Festival production for achieving higher yields is the availability of strawberries with better quality. The experiment was carried out during the period from November 2020 to March 2021 to find out the responses of gibberellic acid (GA3) and mulch materials on biochemical and quality attributes related to strawberry yield characteristics. The experiment consisted of two treatments including different mulch materials: black polythene, white polythene, sawdust, and control (no mulch); and GA3 (0 and 200 mg/L) were studied. Various quality parameters, namely total soluble solids (TSS), pH, titratable acidity, ascorbic acid, total sugar, phenolic, and anthocyanin content of the strawberries were determined. The results observed in the GA3-treated plants showed more significant results than the plants not treated with GA3. Among the mulch materials, sawdust performed better than the other mulch materials in terms of yield, biochemical, and quality attributes. The highest fruit set percentage (89) and fruit yield (18.70 t/ha) were obtained from the GA3 and sawdust mulch treatments. GA3 and sawdust mulch performed best in terms of quality parameters including TSS, pH, ascorbic acid, total sugar, phenolic, and anthocyanin content. Accordingly, sawdust and GA3 are more responsive to strawberry plant quality parameters. These findings provide practical insights for sustainable strawberry cultivation practices, contributing to increased fruit availability and improved nutritional value for consumers.
