Abstract:A series of experiments was conducted for three years (1968-70) at the Institute for Agricultural Research, Samaru, Nigeria, to study the effect of stand density of long-season dwarf photosensitive varieties and hybrids on yield and to determine the optimum stand density for maximum yields. Good yields were obtained over a range of 50-90.000 plants per ha and the optimum harvest density is about 65.000 per ha. This is double the optimum population for best yields of tall long-season photosensitive varieties. The average yield of the dwarf variety in 1970 where stern-borers were controlled was 4.3 tons per ha. Notes, table, figures.
