I NTRODUCTION ( CONT ’ D ) Maize area, ha (FAOSTAT, 2010) Total 161, 765, 388 ha Sub Saharan Africa 30, 910, 018 ha Planted by hand (60%) * 18, 546, 011 ha Potential yield increase (25%)* 15, 895, 059 Mg (single seeds cm apart) Yield increase of 25% for 60% hand planted maize worth more than 4.6 billion dollars/ year (corn price at $ 0.295/kg) *From( )

L ITERATURE R EVIEW Plant Spacing Narrow: tall and weak steam plants, decreased yield due to lodging (Rowland, 1993; Futuless et. al, 2010) Wider: Encourage weed and pests infestation, influences maize yield (Whiteman, 1981) Increased row spacing from 0.35 to 1m will decrease grain yield (Riahinia and Dehdashti, 2008) Light Interception Development of crop growth related to light interception (Gardner et al., 1985) Optimization of light interception increased grain yield (Stewart et al., 2003) Light interception can be increased by reduced row spacing (Andrade et al., 2002)

O BJECTIVE To determine the value of equadistant plant spacing when compared to “hills”, placing 2-3 seeds per hill M ATERIALS AND M ETHODS Locations: Lake Carl Blackwell research station and Efaw research station Cropping year: Summer 2011 and Summer treatments with 3 replications arranged in RCBD, middle two rows planted by hand Preplant N rate: kg N ha -1 applied in the form of urea (46-0-0) Light Interception, LI-COR

W EATHER Total monthly rainfalls (mm), surface air temperature (°C) in Lake Carl Blackwell and Efaw research station, Oklahoma,

C ONCLUSION Trend for decreasing yields with increasing number of seeds per hill (same population) range (200 to 1000 kg/ha) except Efaw research station, Trend for decreasing IPAR with increasing number of seeds per hill (same population) range ( 6 to 17%) except Efaw research station, 2012 IPAR was correlated with final grain yield. Excessive heat lowered yield levels and decreased the ability to decipher treatment differences
