Interactive effects of banana stem ash and potassium-solubilizing fungi on peanut (Arachis hypogaea L.) growth and yield
Peanut (Arachis hypogaea L.) productivity in Indonesia averages approximately 1.0 t ha⁻¹, far below its potential yield of 3.5 t ha⁻¹, mainly due to poor pod filling associated with low soil potassium (K) availability. This study evaluated the integrated application of banana stem ash (BSA) containing 23.6% K₂O and pot...
