“…El rango en el sistema de riego por superficie fue de 3.62 a 3.92% (Cuadro 2). Comportamiento similar a lo reportado por Carvalho et al (2016) en el que mencionan que las mejores condiciones de agua proporcionan al maíz una rápida expansión celular, con anticipación al proceso de lignificación de los tejidos.…”

La eficiencia en el uso del agua para la producción de forraje agrupa una serie de componentes relacionados con el cultivo y el sistema de riego que consiste en obtener una mayor producción por unidad de agua consumida. El objetivo del trabajo fue conocer el rendimiento, calidad nutricional y la eficiencia en el uso del agua (EUA) del cultivo del maíz forrajero (Zea mays L.) en dos sistemas de riego bajo tres niveles de evaporación aplicada. El trabajo se estableció el 19 de abril de 2019, en el Campo Experimental La Laguna (CELALA) del Instituto de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) ubicado en Matamoros, Coahuila, México. Los sistemas de riego evaluados fueron: goteo subsuperficial y riego por superficie. En ambos sistemas, las láminas aplicadas correspondieron al 100, 75 y 50% de evaporación libre del tanque evaporímetro clase ‘A’. La cosecha se realizó cuando el grano se encontraba en la etapa de grano lechoso R3. El diseño experimental utilizado fue de parcelas divididas con cuatro repeticiones. La interacción sistema de riego por goteo subsuperficial -100% de evaporación fue superior (p< 0.05) en las variables altura con 2.05 m, rendimiento de forraje verde con 55.08 t y rendimiento de forraje seco 14.85 t. La combinación con mejor comportamiento en EUA en rendimiento con 1.98 kg m-3 y valores más altos en EUA en calidad del forraje, fue el sistema de riego por superficie -75% de evaporación. Se mostraron diferencias significativas entre sistemas de riego en las variables de calidad con mejores resultados en el sistema de riego por superficie.

“…Maize is one of the most important crops in Brazil, with area and yield of 15.92 million hectares and 4.17 t ha -1 , respectively, in the 15/16 growing season (Conab, 2016). Maize grains are used as raw material in the industry, as well as in natura or processed food for both human and animal consumption (Sousa et al, 2012;Carvalho et al, 2016). Therefore, maize seeds are classified according to their size and shapes (Andrade et al, 1997).…”

The objective of this work was to evaluate the influence of seed size and shape on physiological performance and respiration, as well as to establish the relationship between physiological quality and respiratory activity of maize seeds. For studying the influence of size and shape of the different seed fractions, the following analyzes were performed: weight of one thousand seeds, germination, first germination counting, germination speed index, total seedlings dry mass, electric conductivity, cold test without soil, seeds respiratory activity, seedling emergence and emergency speed index.The data were submitted to analysis of variance, the variables were compared by the Tukey test. Pearson's correlation test was performed between seed shapes and sizes, and the attributes of physiological quality. The small flat seeds from genotype "A" present higher physiological quality than large flat, large round and small round seeds. Whereas, for genotype "B", seeds with the highest physiological quality are the flat shapes, regardless their size. Respiratory activity in both genotypes was not sensitive for detecting differences of vigor between different sizes and shapes. There is significant correlation between large flat seeds, as well as between small flats and large rounds and small seeds with germination speed index. Similarly, there is correlation between the different shapes and sizes with electrical conductivity.

The aim of this study was to evaluate the chemical composition, growth of microorganisms, and the aerobic stability of high-moisture corn grain silage inoculated with Lactobacillus plantarum + Propionibacterium acidipropionici. The experimental design was completely randomized in a 2 x 5 factorial arrangement with four replications (50 experimental units) and the treatments were: use or not of microbial inoculant (2 x 105 colony forming unit (CFU) g-1 Lactobacillus plantarum + Propionibacterium acidipropionici) and the storage length for 0, 1, 3, 7, and 14 d. Aerobic stability of silage was evaluated at 28 and 56 d of storage length. The lactic acid bacteria population was influenced by storage length and the greatest values were estimated at 8 d of storage length. Regardless of inoculant application, no enterobacteria were present from 3 d post-ensiling. With respect to mold growth, an interaction between inoculant and storage length was observed wherein molds were most abundant after 3 d of storage in silage that received inoculant. However, at 14 d of storage the use of bacterial inoculant reduced the occurrence of molds. pH values obtained after 3 d of ensiling were less than 4.0 for all the treatments. The high-moisture corn grain silage possessed good fermentative quality. Further, adequate pH values were achieved from the third day of ensilage and were not influenced by the presence of bacterial inoculant.
