Effect of rice-husk ash on exchange acidity, growth and yield of groundnut (Arachis hypogaea l.) in an acid ultisol
Global Journal of Agricultural Sciences
Response of groundnut grown on acidic soil to rice-husk ash applied at 0, 1, 2, 3 and 4 t ha -1 was studied in two field experiments in 2005 and 2006 at Ishiagu in the derived savanna zone of southeast Nigeria. Treatments were fitted in a randomized complete block design (RCBD) replicated three times. Effects of treatments on some soil fertility and productivity parameters were evaluated. The rice-husk ash used contain 64.00 g kg -1 Ca, 12.20 g kg -1 Mg, 12.50 g kg -1 P, 9.00 g kg -1 K, 2.10 gdoi:10.4314/gjass.v8i1.48514 fatcat:gqw2obuv7vbflm6f7yukjjbkom
