Abstract:
Sorghum and Sudan grass are grown for grain and also for forage in
areas with inadequate rainfall for satisfactory maize cropping. There are
many varieties of Sorghum and Sudan grass, but the composition of their
grain does not differ enough to affect significantly their feed qualities.
Sorghum and Sudan grass requires similar soil conditions to maize but can
grow in drier climates. Sorghum is grown on 44 million ha in 99 countries in
Africa, Asia, Oceania, and the Americas, and the major producers are the
USA, India, Nigeria, China, Mexico, Sudan and Argentina. Sorghum and
Sudan grass can be grown successfully grown on a wide range of soil types.
There are tolerates a range of soil pH from 5.0 – 8.5 and are more tolerant to
salinity than maize. Also, there are adapted to poor soils and can produce
grain on soils where many other crops would fail. Sorghum and Sudan grass
can produce a significant amount of forage in a short time, 5 to 6 weeks after
seeding. In this paper we observed the role of sorghum and Sudan grass in
assuring the fodder base in the less favourable years, in the conditions of the
NE of the Romania. Also, we observed the influence of fertilization on the
productivity potential and the quality of these two species, cultivated for
fodder and silage. We marked the fact that higher productions and the best
quality were at both species in the case of the variants fertilized with 30 t/ha
manure, applied in spring.
