The objective of this study was to evaluate the effect of season and regrowth age on the herbage yield, morphological composition and structural characteristics in Insurgente grass. Three regrowth age were studied (RA: 28, 35 and 42 days) in three seasons of the year (rainy, north, dry), in a completely randomized block design in a split plot array, with four replicates plots. The following attributes were taken into account, herbage yield, plant height, morphological composition and leaf: stem and leaf: no leaf ratio. The distribution of herbage yield was 30, 5 and 65 % for rainy, north and dry seasons, respectively, with an annual average accumulation of 10.869 kg DM ha- 1 and 32 cm plant height.

El pasto Insurgente (Brachiaria brizantha) cv. Marandu, es una opción como especie forrajera a utilizar en las regiones tropicales (Castro

et al., 1994) debido a su alto rendimiento, buena calidad de forraje y excelente aceptación por el ganado, además de ser resistente a sequía, quema, plagas y enfermedades y adaptarse a suelos ácidos de baja fertilidad (Gerdes et al., 2000; Castro et al., 1994; Yuseika et al., 2006). Sin embargo, al igual que la mayoría de las gramíneas forrajeras tropicales, el principal problema para incrementar su propagación, es la baja oferta de semilla de alta calidad.

The objective of this study was to evaluate two seed sizes in the physiological quality of orchard grass and perennial ryegrass (Dactylis glomerata L., Lolium perenne L.). The treatments were two sizes of seed (large:LS and small:SS). The variables were: emergence (EM), abnormal seedlings (AS), non-germinated seeds (NGS), establishment (ES), viability (VI), speed of emergence (SE), seedling height (SH), and root length (RL). A CRD with 4 repetitions were used. It was observed that, regardless of the size, the EM was higher in perennial ryegrass (p¿0.05), compared to orchard

grass, due to it presenting the highest (p¿0.05) percentage of AS and NGS.

Alfalfa (Medicago sativa L.) is the most commonly used legume forage in the diet of dairy cattle in the United States

and Mexico. The objective of this research was to evaluate the productive response of five alfalfa varieties with defined

cutting intervals seasonally. The research was conducted from June 2010 to June 2011 in the Colegio de Postgraduados, Mexico. Commercial varieties evaluated were: San Miguelito, Jupiter, Atlixco, Via lacteal and Cuf 101, which were randomly distributed into 20 experimental plots of 12 x 9 m, according to a randomized complete block with four replications. The variables evaluated were: growth rate, intercepted radiation, leaf area index and plant height. Jupiter and Cuf 101 varieties with 56 and 37 kg DM ha-1 d-1 recorded the highest and lowest growth rate, respectively.
