Response of Maize (Zea mays L) and Soil Properties to Oil Mill Effluents in Ultisol of Emerging Biotechnology in Nigeria.
Main Article Content
Abstract
The effects of oil mill effluents on Maize performance and selected properties of ultisol in Ihiagwa, Southeastern Nigeria were studied in 2013. The response of Maize to (0.0,2.0, 2.5,3.0, 3.5 and 4.0 m3 per hectare) of oil mill effluents application was evaluated using complete randomize design (CRD).Every treatment was replicated 3 times, thus total of experiment was 18units. Soil samples were taken at a depth of 0 – 20cm, air-dried, and sieved with a 2-mm mesh for laboratory analysis. Maize grain yield, plant height, dry matter weight and soil residual physico-chemical properties were evaluated. The results showed that application of palm oil mill effluents (POME) had significant effect on Maize performance and some soil physico-chemical characteristics. Maize grain yield, dry matter weight, N,P,K contents and residual organic C, and Soil pH were improved. Exchangeable Al in soil of the studied area decreased with increasing levels of palm oil mill effluents and the growth of maize generally. The research demonstrated thatthe treated soils with fermented POME significantly produced higher grain yield, dry matter, and favourable soil properties tested than plots that received sustainable agriculture. The best maize performance and soil propertieswas in 3.5 m3/ha of palm oil mill effluents.
