Abstract
In field trials in 1967 in which grain sorghum hybrids heading 55, 60 and 70 days from emergence were sown at 12 plant densities ranging from 2.9 to 27.9 plants/m2, the highest yield was obtained from the earliest hybrid at the most dense population. The grain yields of the late- and of the early-maturing hybrid were highest under low and high plant densities, respectively. The higher yields were due to higher yield/plant, number of heads/plant and number of grains/panicle. All grain yield components affected inter-hybrid differences under moderate competition, but at the highest plant density the interaction between number of grains/ panicle and weight/grain determined yield; 1000-grain weight of the early hybrid was unchanged by increased plant competition for water. In a second experiment in 1969, less water was used by an early-than by a late-maturing hybrid. Water use increased with plant density.-P.C.H.
