Abstract
An experiment was carried out to assess the growth and development of quality protein maize (QPM) genotypes to various plant populations under different irrigated conditions in a semi arid ecology of Northern Nigeria. Field trials were conducted at the Irrigation Research Station, Institute for Agricultural Research, Kadawa (11 o 39’ N, 08 o 20’ E) and 500 m above sea level) for three years, 2007, 2008 and 2009 during dry seasons to study the effect of three maize ( Zea mays L .) genotypes (TZE - W Pop X 1368, EV - DT W99 STR and DMR - ESRW), four plant populations (33,333, 44,444, 55,555 and 66,666 plants ha - 1 ) and three irrigation scheduling regimes (40, 60 and 80 centibars soil moisture tension) on the growth and development of QPM. This was a three trial experiment with factors arranged in a split plot design, whereby genotype and irrigation scheduling
