The dry matter (DM) yield and quality of five hibrid fooder sorghum: Sudax ST-6 (I), Sudán Cross 3 (II), Trudán 8 (III), Sucro Sorgo 405 (IV) and Suero Sorgo 301 (V) were evaluated from November to April (1988/89 qrowing season) under irrigated land conditions. Twenty five kg/ha of seed rate were sown in lines at 0.5 m aparto Nitrogen (117 kg/ha), P (48,5 kg/ha) and K (48 kg/ha) were applied at sowing. After the first and second cut 60 kg/ha of N were applied. The plots were irrigated five times between December and March. A randomized block design with 5 treatments and 3 replication was used. The plants were cut when they reached 60 cm high and 5 cm of stubble were left. The sampling two area was 5 x 2.5 m (12.5 m2). Dry matter production, leaf: stem ratio, crude protein (C.P.), acid detergent fiber (A.D.F.) and total digestible nutrients (T.D.N.) were measured. Dry matter yield per cut and total of five hibrid were not different (P > 0.05), except at the firsí cut when the treatments I (Sudax ST-6) and V (Suero Sorgo 301) had higher (P > 0.05) yield (3.14 ton/ha of D.M.) than the treatments III and IV. Yield per cut and total dry matter showed no differences (P < 0.05) among hibrids, except for the yields obtained in the first cut where treatments I (Sudax ST-6) and V (Sucro Sorgo 301) had greater yields (P < 0.05) with a top of 3.14 ton m.s./ha in relation to híbrids III (Trudán 8) and IV (Suero Sorgo 405). Stem contríbutíon to the total dry matter yield and acid detergent fiber showed differences between sorghums (P < 0.05). However, leaf contribution, crude protein and total nutrients were statistically the same (P < 0.05).
