Résumé
A pot experiment was conducted in the nursery of the Faculty of Agriculture, University of Khartoum, Shambat latitude 15°40’N. longitude 32°32’E, for one season (2016/2017) to study the effect of salt concentration (NaCl) and water on growth and yield of fodder sorghum, pioneer (Sorghum bicolor × Sorghum sudanense). The levels of salt concentration were : S0 no salt, S1 (3g/l), S2( 6g/l) and S3( 9g/l). The levels of water were : 100% (FC), 75%(FC) and 50% FC. The experimental design was completely randomized design (CRD) with three replicates (three blocks). Measurements and calculations made in this experiment were : plant height, fresh weight of whole plant, fresh weight of leaves, fresh weight of stems, dry weight of whole plant, dry weight of leaves, dry weight of stems, leaf/stem ratio, leaf relative turgidity (LRT), chlorophyll content, average relative growth rate)ARGR) and chemical composition of the average nutrients, namely : N,P,K ,Ca and Na, at the age of 21,31,41 and 51 days after sowing. The results showed statistical significant (p˂0.05) in plant height at the age of 31 and 41 days after sowing, Fresh weight of the whole plant at the age of 31 days after sowing, dry weight of stems at the age of 31 after days after sowing, ARGR at the age of 21 days after sowing. There was no significant difference in the other studied parameters.
