Studies on the Productivity of Grain Sorghum. IV. Effect of Various Planting Dates on the Growth, Grain Yield and Protein Content of Irrigated and Nonirrigated Grain Sorghum

Abstract

This field research was conducted at the Nagoya University Farm to examine the effect of different planting dates on the growth, grain yield and protein content of irrigated and nonirrigated grain sorghum planted at various dates. Grain sorghum (Sorghum bicolor (L.) Moench) hybrid H-726 was planted on May 1, 15, June 1, 15, July 1, 1978. Irrigated treatments received water 2 times a week during the growing season, while irrigation was stopped from 6th leaf emergence stage in the nonirrigated treatments. © 1981, CROP SCIENCE SOCIETY OF JAPAN.
