Effect of maturity in the chemical composition and productivity of Paspalum dilatatum (Poir)

Abstract:

Honey grass is a perennial species, very persistent and a wide range of adaptation to edaphoclimatic conditions. The present investigation was carried out in the months of July-September 2015, on a farm, located at Km one of the El Empalme-Balzar road, province of Guayas, Ecuador. with the objective to determine the effect of maturity on the chemical composition and productivity of Paspalum dilatatum (Poir). A randomized block experimental design with three treatments (21, 42 and 63 days) and four repetitions was used. To do this, were used parcels of six square meters (3x2), with a sowing frame of 0,50 x 0,20 m, the response variables were the GMY, DMY, fiber-nitrogen ratio and leaf-stem; as well as DM, CP, CF, EE, ash and NFE. The best results were obtained at 63 d in how many productivity indicators were 11.61; 3,725 t of green and dry matter, respectively; while the nutrient content decreased with the increase in the study period, with the increase in the FB / N ratio (6.81) and decrease in H / T (1,2). It was concluded with the advance of age, quality is affected, yields increase, leaf reduction and more stems.
