Maize Grain

This research aimed to evaluate the maize grain yield and forage of grass species under intercropping system using nicosulfuron herbicide. In order to assess the parameters related to maize, a randomized block design was defined. The treatments were arranged in a (5 × 2+ 1) × 2 factorial design with four repetitions resulting in 11 treatments, where maize was cultivated under intercropping condition with different forage species (5) (Brachiaria brizantha cv. Marandu, Piatã, Xaraés, Brachiaria ruziziensis and Panicum maximum cv. Mombaça) and maize monoculture (1) as control treatment, with and without nicosulfuron herbicide application (2) in two growing seasons (2014 and 2015). The off-season intercropping of maize with tropical forage grasses with and without herbicide suppression decreased maize grain yield. The suppression with nicosulfuron herbicide decreased the dry matter production of forage grasses. Intercropping of P. maximum cv. Mombaça with maize showed higher decrease in maize grain yield. On the other hand, it showed higher forage grasses production for livestock feeding. B. brizantha cv. Piatã was the forage which less affected maize grain yield under intercropping, even with absence of nicosulfuron suppression. Off-season maize under intercropping with tropical forages can be used to recover degraded pastures; increasing forage dry matter production for livestock, remaining the soil covered with straws with possibility of no-till seeding for the next cultivation.

Forage Mixtures

Annual forage mixtures are forage crops consisting of forage grasses (e.g. Italian ryegrass etc.) and annual clovers (e.g. Berseem clover, Crimson clover etc.) or mixtures of spring or autumn vetch with grain cereal (e.g. oats, barley, etc.) that are known as spring or autumn mash. The goal of this paper is to find the functional dependency of the average dry matter production of the Italian ryegrass (in the 67th phenophase) and Crimson clover mixture based on their different percentage participation in order to obtain the technical optimum in two variant of fertilization (N0P0K0 and N100P50K50). For this, we studied Italian ryegrass (I.r.) and Crimson clover (C.c.), both in pure and mixed culture, in the following proportions: I.r.75%+C.c.25%, I.r.50%+C.c.50%, I.r.25%+C.c.75%. In this paper we take in consideration the average dry matter production obtained in the experimental years 2007 – 2011 that allow us to have a few conclusions on the Italian ryegrass production capacity but also about the adaptation capacity of Crimson clover in Banat plain conditions. Results show that in the fertilized variant, there is an increasing of the percentage participation of Italian ryegrass in mixtures for which the maximum of dry matter production is realized than in the case of unfertilized variant, which shows that Italian ryegrass has a better response to chemical fertilizers than Crimson clover.

THE RESULTS of cutting trials which have been designed to provide information on grazing frequency and intensity in pasture rotations have, in both temperate and tropical regions, often shown that lax and infrequent cutting promotes higher dry matter production than does more intensive and frequent cutting, except on prostrate rhizolmatous and stoloniferous pastures These results have, however, seldom been successfully translated into increased animal production where the negative association frequently observed between dry matter production and both herbage quality and the degree of utilization of the dry matter produced often negates the increased production resulting from lax and infrequent grazing. Added to this are the longer term effects of spelling interval and grazing intensity on sward density and botanical composition, these effects varying through the season as the morphological condition of the pasture species changes.
