“…In a study conducted on a degraded tropical Alfisol located in Ondo State, Agbede and Oyewumi [174] investigated the impacts of hardwood BC (pyrolyzed at 580 • C), poultry manure, and their mixtures on the essential nutrient content of sweet-potato leaves and storage roots. The outcome observed indicated that the application of either biochar alone, poultry manure, or their combined treatments at different levels resulted in heightened nutrient concentrations within the leaves and enhanced mineral composition in sweet potatoes.…”

Africa, specifically Nigeria, has witnessed a dramatic increase in population over the last century, prompting efforts to ensure sustainable food production and quality. Concerns for soil sustainability and food security have led to the exploration of cost-effective methods, such as biochar, to enhance soil quality. Researchers in Nigeria and Africa as a whole have investigated biochar’s potential to improve soil fertility and crop performance across various agroecological zones. This paper aims to review recent biochar research priorities on soil fertility and crop performance with an emphasis on various sole biochar applications and combinations with fertilizers to determine the research gaps that need to be developed more in biochar research in Nigeria. From the papers reviewed, sole biochar applications and biochar + macronutrients and biochar + manure combinations were studied more dominantly, while biochar + micronutrients research projects were scanty despite their low content in the semi-arid soils of Nigeria. The studies were spread across the country with the majority taking place in derived savanna and humid forest, while Sudan savanna and Sahel savanna received less research attention despite being characterized by a low-fertile soil and vast area of land. Research involving BC in the context of Sahel savanna (SLS) and Sudan savanna (SS) soils is strongly encouraged in Nigeria. This research should encompass a wide range of investigations, including sole BC applications and combinations of BC with macronutrients, micronutrients, and manure, as well as exploring its potential as a slow-release fertilizer. Incorporating exclusive biochar in substantial amounts appears economically unfeasible within the context of local biochar production. However, it can be utilized in the synthesis of slow-release fertilizers, requiring smaller quantities and potentially offering cost-effectiveness. This approach enhances soil condition and crop productivity. Challenges are faced due to less commercial production as a result of inadequate power and structural facilities. Exploring the modification of local biochar for slow-release fertilizers through future research offers potential profitability.

“…The application of manure improves soil physical properties and is expected to enhance growth and yield. According to [5], besides providing nutrients, manure can promote the growth of plants and larger tubers. Furthermore, nutrient elements in the substrate can be activated through the application of manure, stimulating the absorption of plant nutrients, increasing nutrient content, and supplying the necessary nutrients for the accumulation of dry matter [6].…”

Amorphophallus muelleri (known as "porang" in Indonesia) can be used as a high-value alternative food source and potentially be a glucomannan production source. Due to its limited production, Indonesia has yet to meet the Amorphophallus muelleri (konjac) flour demand. During growth, konjac plants require sufficient fertilization to increase production and yield large tubers. This study aims to determine the appropriate types and doses of manure fertilizers to enhance konjac plant productivity. The research employed a randomized complete block design with ten treatments using sheep, chicken, and cow manure, as well as a control, with doses of 1.5, 1, and 0.5 kg per plant, repeated four times. The results showed that using manure fertilizers significantly affected the growth of konjac plants, including plant height, stem diameter, leaf width, canopy diameter, and yield. The best dry weight results were obtained using chicken manure at 1 kg per plant (61.33 g) and 1.5 kg per plant (47.64 g). Using sheep, cow, and chicken manure increased konjac tuber yield by 94.95%, 93.55%, and 66.96%, respectively.
