Effect of Sowing Time and Photoperiods in Sorghum Roxburghii var. hians, Stapf. (Jowar)

Abstract

SEEDS of Sorghum Roxburghii var. hians were sown for one year at intervals of one month commencing February 15, 1949. Owing to a limited number of available seeds, about twenty seeds were sown in single small plots (5 ft. × 3 ft.). Although there was a good percentage of germination in all the sowings except those of November 15, 1949, December 15, 1949, and January 15, 1950, only a limited number of plants varying between three and nine for the different sowings survived until the flowering stage. The date of first emergence of the panicle out of the top flag leaf taken as the flowering date and the height at flowering were noted separately for each plant, and the mean data are given in Table 1.
