520			_aThe effect of light stress originating from artificial partial shading and from self-shading caused by dense planting on the grain yield of five maize communities differing genotypically in earliness was studied. The sensitivity of plants in different growth stages to light stress was also investigated. Finally, the possibility of relieving the light stress by manipulating leaf inclination was tested in dense populations. Increasing the density of a 5 plants/sq m community by two and a half times seemed as detrimental for grain yield per plant as decreasing the community's illumination by half by shading. The relative performance of hybrids was changed both by
