Data and planting density on the production and quality seed the triticale (X Triticosecale Wittmack).
objective of this study was to evaluate the effects of sowing
dates and seeding rates on triticale seed yield and quality.
This work was performed during the autumn-winter season
in 2006-2007, at the research station of The Technological
Institute of Roque, located at km 8 of the highway Celaya-
Juventino Rosas, Celaya, Guanajuato, Mexico. We used three
cultivars of triticale of different genetic origin (Roque I, AN-
31 and AN-105) with one formula per hectare of 120-100-
100, NPK. Three sowing dates were evaluated, November
9, November 23, and December 7, and fi ve seeding rates
at each planting date, 50 kg/ha, 75 kg/ha, 100 kg/ha, 125
kg/ha and 150 kg/ha. The variables evaluated were plant
height, ear length, seed yield, vigor, and germination. The
experimental design was a randomized complete block
design with a factorial arrangement. The optimal sowing
date for seed production was November 9, resulting in a
yield of 5,305 t/ha. This treatment resulted in the highest
values for ear length, plant height, vigor, and germination.
When selecting important traits to produce high quality seed,
through sowing density, the highest plant population was
obtained with 125 kg/ha resulting in a yield of 3,834 t/ha,
vigor of 82.0% and germination of 89.83%.
