Sorghum Growth and Yield as Influenced by Farmyard Manure and Inorganic Fertilizer in Post Mined Soils

Mining plays an important role in Kenyan Economic development through provision of employment, raw materials as well foreign income. Despite the played by this sector, it is associated with land degradation, impacting food security. Closure mines calls for rehabilitation process establishment native trees, grass or crops. In order to promote crop production a reclamation measure, performance sorghum post mined soils was evaluated south dune site base titanium limited Kwale Company. The experiments were laid down Randomized Complete Block Design (RCBD) split plot arrangement and replicated thrice. Fertilizer, Manure, Manure + Control (unfertilized) Gadam Silla varieties tested. Data collected included: Initial soil properties, plant height, number leaves, leaf length, width, stem circumference, panicle circumference grain yield per hectare. subjected analysis variance using Genstat software means separated Fisher’s protected least significant difference at (P≤0.05). slightly acidic low levels exchangeable P, K, S, Cu Bn. fertilizer significantly (P≤0.05) increased height 14% (gadam), 28% (silla), leaves (gadam) 29% length 18% 8% dry matter 30% 40% (silla) 50% both gadam silla compared control plots varieties. Average yields seasons manure treated plants high (5.3 tones/ha) variety (5.7 variety. Where produced than 7%. Combined application farmyard inorganic most effective enhancing growth, yield. Growth data showed that combined can support optimal soils. Owing fact have compromised profile, structure fertility, long term trials simulation models are required ascertain while ensuring sustainable health such
