Abstract

CABRALES, Roberto; MONTOYA, Rafael  and  RIVERA, Jaime. AGRONOMIC EVALUATION OF 25 GENOTYPES OF MAIZE (Zea mays) for FORAGE PURPOSES IN THE HALF SINU VALLEY. Rev.MVZ Cordoba [online]. 2007, vol.12, n.2, pp.1054-1060. ISSN 0122-0268.

Objective.To evaluate agronomically 25 genotypes of maize for forage purposes. Materials and methods. This research was carried out in Turipaná Investigation Center belonging to CORPOICA at Córdoba department. A lattice design 5x5 was used, with 36 treatments and three repetitions by treatment. Results. Higher yields were showed by the following maize genotypes: HIT 34 with 63.52 Ton/ha of fresh matter, 22.11 Ton/ha of dry matter and 3.10 Ton/ha of grain; VERA 225 with 61.13 Ton/ha of fresh matter, 20.11 Ton/ha of dry matter and 4.37 Ton/ha of grain; SNLP 111 with 60.62 Ton/ha of fresh matter, 19.20 Ton/ha of dry matter and 4.69 Ton/ha of grain; ICA V 156 with 54.51 Ton/ha of fresh matter, 17.1 Ton/ha of dry matter and 4.41 Ton/ha of grain; for prolificacy showed like better genotypes the VERA 225 with 1 ear per plant, being the second genotype in production of fresh matter and one of the higher in grain production; in grain index SNLP 111 was the greatest with 82.87%, outstanding as the genotype of higher production of grain, the relation of dry matter of leaf-stem-ear were better represented by the genotypes CUBA 91 with 33.63%: 20.43%: 45.97% and ICA V 156 with 32.33%: 24.43%: 43.23%, respectively. Conclusions. There are good genotypes of maize to be use by farmers in silage processes.
