Influence of planting method on growth curve of Pennisetum purpureum cv King Grass in the Ecuadorian Amazon

Abstract

The work was performed at the Research Station of pasture and forage CIPCA belonging to the Amazon State University. And age (x: regression analysis between the variables height ( dependent variable y): was made independent variable grass Pennisetum purpureum cv King grass and the effect of planting system on site , on two plots of 20 m2 on a floor Inseptisol . land preparation is done manually and consisted only veneered area prior had done a soil test selected stakes, with four knots were placed at 5 cm deep , 25 cm distance between plants and 70 cm between rows . at 19 days of age germination was measured differences in the% where the sloping method had the highest percentage 100%, I turned both plots reap the inclined seed yields 9.23 t / h were observed dry matter lying against 5.06 for planting. values obtained for a cut without the use of fertilizers or pesticides. Based on weekly measurements of height growth curves rate growths were performed and the linear regression quadratic.
