Agronomic efficacy of compost manure and NPK fertilizer on some soil chemical properties and maize production in an ultisol environment
Journal Title: Journal of Applied and Natural Science - Year 2012, Vol 4, Issue 2
Abstract
Studies were conducted as an on-farm trial at Evboneka in 2009 and 2010 cropping seasons to estimate the effect of soil amendments in enhancing soil fertility status and relative agronomic efficacy of maize yield in humid ultisol environment. Effects of compost was investigated at application rates of 20 and 40 t ha-1 while NPK and organo-mineral fertilizer effects were investigated at 200 kg/ha and a combination of 100 kg/ha NPK and 20 t/ha compost manure (organo-mineral fertilizer) with maize TZEE-W cultivar resulting in five treatments and replicated three times. The results obtained revealed that the tested soil was low in organic matter, total N, available P, moderately acidic and low cations (Ca, Mg and K). The compost manure was rich in N, P, Mg, K, organic carbon and Ca concentration. The application of compost manure and NPK to the soil improved the soil fertility status. The highest maize height (132.70 cm), greatest total dry weight (0.63 t ha-1) and relative agronomic efficacy (%) were obtained from plots treated with 40 t/ha-1 compost manure while the plots treated with organo-mineral had the greatest LAI (2.75).
