Okra or Lady’s finger, botanically known as Abelmoschus esculentus (L.) Moench, is a tropical and sub-tropical indigenous vegetable crop commonly grown for its fibrous, slimy, and nutritious fruits and consumed by all classes of population. It has also several medicinal and economic values. Despite its many uses and potential value, its importance is under estimated, under-utilized, and considered a minor crop and little attention was paid to its improvement. The study was conducted to evaluate the effects of different planting densities and mulching materials on the growth and yield of okra grown in slightly sloping area in the marginal uplands in Sta. Rita, Samar, Philippines. A split-plot experiment was set up with planting density as main plot and the different mulching materials as the sub-plot which were: unmulched or bare soil, rice straw, rice hull, hagonoy and plastic mulch. Planting density did not significantly affect the growth and yield of okra. Regardless ofthe mulching materials used, mulched plants were taller and yielded higher compared to unmulched plants. Moreover, the use of plastic mulch resulted to the highest total fruit yield. The results indicate the potential of mulching in increasing yield and thus profitability of okra production under marginal upland conditions.

Use of biochar for soil fertility improvement is gaining popularity due to its potential to improve soil quality, increase crop yield, and sequester carbon from the atmosphere-biosphere pool into the soil. A 40-day pot experiment was carried out to investigate the effects of corncob biochar and compost applied alone (at a rate of 2%, w/w) or in combination (1% of each, thus 1% compost + 1% biochar) on soil physicochemical properties, growth, and yield of maize on two soils of contrasting pH and texture collected from the Rainforest and Coastal Savannah agroecological zones of Ghana. Biochar and compost applied alone or in combination significantly increased soil pH, total organic carbon, available phosphorus, mineral nitrogen, reduced exchangeable acidity, and increased effective cation exchange capacity in both soils. Additionally, combined application and single application biochar or compost additions increased the plant height, stem girth, and dry matter yields of two maize (local (“ewifompe”) and hybrid (Obaatanpa)) varieties used in the study. The study showed that biochar applied alone or in combination with compost offers the potential to enhance soil quality and improve maize yield.

Field trials were conducted at the University Orchard Aliero, Kebbi state University of Science and Technology Aliero, during the 2017 and 2018 dry seasons, to study the  growth and yield of Okra (Abelmoschus esculentus L. Moench) varieties influenced by sole and combined application of NPK (15:15:15) and Poultry manure. The treatments consisted of a factorial combination of three Okra varieties: LD88, NHAE47-4 and Dogo; and three level of nutrients: 800 kg NPK (15:15:15) ha-1, 100%PM ha-1 equivalent to 6.6 t ha-1 and 50% NPK+50% PM ha-1 (400 kg of NPK [15:15:15] + 3.3 t of PM ha-1) and the untreated control, each designed to supply the recommended dose of 120 kg N ha-1 using a compound fertilizer NPK (15:15:15) and poultry manure and cow dung. Results revealed that plant height, number of leaves, number of pods per plant, mean pod weight (g), mean pod length (cm), fruit yield per hectare were significantly increased when the recommended N dose of 120 kg N ha-1 was applied using only NPK (800 kg NPK [15:15:15 ha-1]) or a combination of NPK+PM at 50:50 ratio in conjunction with variety NHAE47-4. Based on the results of this study, it could be concluded that the integration of organic and inorganic fertilizers in form of NPK fertilizer and poultry manure at 50:50 ratio in conjunction with variety NHAE47-4, could be adopted for higher pod yield.
