Impact of Cropping Ratios of Maize (Zea mays)-Egusi Melon (Colocynthis citrullus) and NPK Fertilizer on Soil Productivity Rating of an Ultisol of Edo State in Nigeria

J. O. Ehigiator, E. J. Falodun, G. O. Iremiren & E. J. Airueghian · Journal of Experimental Agriculture International · 2015

Three separate field studies were conducted at the Research Farm of University of Benin  in Nigeria to determine soil productivity index rating for ultisol in which seven cropping ratios of maize (MA) and egusi-melon (EM) Viz 1:0, 0:1, 1:1, 2:1, 3:1, 1:2 and 1:3) were tested usin...

Influence of Plant Density and NPK 15:15:15 Fertilizer on Some Agronomic Characters and Proximate Composition of Onion (Allium cepa L.) in Edo Rainforest of Nigeria

E. J. Falodun & J. O. Ehigiator · International Journal of Plant & Soil Science · 2015

The effect of plant population density and varying levels of NPK 15:15:15 fertilizer on the growth, yield and proximate composition of onion (Allium cepa L.) was investigated in a 2-year study, 2010/2011 and 2011/2012. The experiment was a factorial combination of three plant den...
