Effects of Population Density and Planting Pattern on the Yield and Yield Components of Leafy Reduced‐Stature Maize in a Short‐Season Area

摘要: Maize hybrids that yield well, mature earlier with low grain moisture contents, tolerate higher population densities and take advantage of narrow row spacings better than the currently available would be more suitable for production in short-season areas. Leafy reduced-stature maize hybrids, which have only recently been developed, traits address these criteria. The objective this study was to evaluate effects different (65 000 130 plants ha -1 ) planting patterns (single rows 76 cm apart paired 20 between within a pair 56 adjacent pairs) on components two leafy (LRSI LRS2), one non-leafy (NLRS), conventional corn (Pioneer 3979, <2500 CHU; Pioneer 3902, 2600-2700 CHU) at locations. All had kernel numbers per single plant yields lower when rows. However, as density increased, variables decreased LRS NLRS demonstrates greater tolerance latter stresses associated densities.
