Regeneración de la pradera artificial con la aplicación de enmiendas e incorporación de especies forrajeras nativas-naturalizadas e introducidas

Abstract

At "Llangahua" community from the Salado zone, Pilahuin Parish, Ambato city, Tungurahua Province, it was determined the different terrains of forage production from the project "Recovery of the farming productive potential at the wastelands of Chimborazo and Tungurahua, taking of from the experience generated by the P: B: 1: D016 project, Settlement and Management of Germplasm of Native and/or Highland Naturalized Forage Species", primary forage production at pre blooming stage from the naturalized promissory species Arrhenatherum elatius and the introduced species, Trifolium repens, Trifolium pratense, Lolium multiflorum, Dactylis glomerata, with the application of corrections, by using calcium carbonate (CaCO3) in a quantity of 1250 kg/ha on the three treatments. The research work included a total area of 1200 m², displayed in three experimental units, of 400m (20m x 20m) each one, made up of three plots of 133,33m², which represent the three repetitions per treatment, which were evaluated out of a Design of Completely Randomize Blocks (RCBD). Determining this way that T2 (Arrhenatherum elatius + CaCO3) showed the best results with a root taking percentage of 95.59%, occurrence time to pre blooming of 51.67 days, production of green forage 5.87 Tn/ha/cut, dry matter 2.09 Tn/ha/cut, plant strength of 9.04 and 9.00 to 30 and 45 days correspondingly. High resistance to drought and tolerance to illnesses according to excellent scale, showing similar behavior on the three experimental units, having a benefit/cost of 1.94; so it is recommended to use Arrhenatherum elatius + Ca CO3, 1250 kg / ha.
