Evaluation of soils fertility, growth, nutrient uptake and yield traits of peanut under indigenous and effective microorganism fertilizers in sandy ferralitic soils in Douala, Cameroon

Soil fertility, growth, nutrient uptake and yield traits of peanut (Arachis hypogaea L. var. JL24) were investigated under two organic fertilizers (indigenous microorganisms (IMO) or effective microorganisms (EM) with three replications. Application of IMO or EM fertilizers had significant effects on soils fertility compared to untreated soils. Total nitrogen, organic carbon, total phosphorus, calcium and magnesium led...

Metribuzin and 2,4-D as potential herbicides for weed management in sorghum [Sorghum bicolor (L) Moench]

Grain sorghum demand for industrial and domestic uses has triggered increased production of sorghum. Field experiment was conducted at Egerton University Njoro, Kenya to determine the most effective herbicide(s) for weed management in sorghum. The experiment was carried out in a randomized complete block design (RCBD) with nine treatments replicated three times. The treatments consisted of four pre-emergence herbicides...

Exploring on-farm additive common bean yield potential to organic and mineral fertilizers on contrasting soils of Buganda Catena, Central Uganda

Mineral and organic fertilizers have great potential to enhance crop yields in low fertility soils of the Buganda catena. However, the need for site-specific knowledge on use and yield of the two fertilizer types in a complex soil scape is acute among smallholder farmers exploiting any soil differences. This study evaluated on-farm grain yield response of common bean (Phaseolus vulgaris L.) to organic and mineral N and...

Agronomic feasibility of using basalt powder as soil nutrient remineralizer

Tropical agriculture is highly dependent of soluble fertilizers, what raises the cost of production. An alternative to reduce the costs inputs is the use of low-cost alternative nutrient sources, such as the basic rocks. The aim of the work was to evaluate the effect of basalt powder on the soil chemical properties and plant growth. The experiment was arranged in a 2×2×2×3+4 factorial scheme: two soils...
