Abstract:
Corn silage is the most efficient way of feeding the animals during the grazing period, with a very high degree of consumability. The success of corn silage cultivation depends largely on the proper choice of hybrid, but also on the pedoclimatic conditions of the crop area. The characteristics and the suitability of the hybrid have an important role in
the maize culture for silage, but in order to obtain superior productions from a qualitative and quantitative point of view, the technological elements and their application must be respected. The density of corn crop for silage is considered the most important technological element. All the improvements of the maize crop, the introduction of the most productive maize hybrids, the fertilization, the irrigation, etc., have led to new levels of production, changing each time the optimum plants density. The research was conducted in 2018 in the pedoclimatic conditions corresponding to the Depression Jijia – Bahlui. Three experimental factors were studied, as followed: the influence of plants density, the distance between the rows and the hybrid on the production of dry matter (DM). The obtained results showed that the technological factors (the density of plants and the distance between rows) caused changes in the biomass production,
the quantity of dry matter being influenced by the hybrid, as well as the plants density and the distance between rows. As the density of plants per hectare increases, the amount of dry matter decreases thus registering at all three densities, reduced production differences.
