Effect of Urea Fertilization on Growth and Yield Of Rhodes Grass (Chloris gayana L. Knuth)

Abstract

The experiment was conducted at experimental farm season 2016/2017 at the Collage of Agricultural studies –shambat- Sudan University of Science and Technology. The objective of this research to investigate the effect of urea fertilizer on growth and yield of (Chloris gayana -Var. reclimer). The experiment was laid out using the design of Randomized Complete Block Design (RCBD) in three replication, The parameter of plant growth studied was as follows: traits are plant height(cm), 50% flowering and yield components were fresh yield t/ha and dry yield t/ha. Analysis of variance showed significant difference of fertilizer on plant height, fresh yield and dry yield(t/ha), on the other hand no significant in 50% flowering; using N2 obtained the best result in tern of fresh and dry weight (26%-34%) respectively. The range of fresh fodder productivity was 11.7-15.9 t/ha and the yield of dry fodder was 3.3-5 t/ha
