Growth and Grain Yield of Pearl Millet (Pennisetum glaucum) Genotypes at Different Levels of Nitrogen Fertilization in the Southeastern United States

Abstract

According to Andrews, Majumdar and& Doggett (1975) there are three types of tillering in pearl millet: synchronous, non-synchronous basal tillering and sub-terminal tillering. With sub-terminal tillering, the tillers arise from the auxiliary buds, whereas in the synchronous and non-synchronous tillering, the tillers arise from the basal leaf bud axils. Based on the sub-terminal tillers, genotype 606A1 x 2304 produced significantly more tillers than all the other genotypes for both 2009 and 2010.
