Abstract
An experimental study was conducted to
examine and determine the effect of urea fertilizer doses on the growth of
dwarf elephant grass (Pennisetum purpureum cv. Mott) at a family farm in Loru Village, Sigi Biromaru District, Sigi Regency. The planting
materials were the grass pols planted in plots of 12.5 m2 each. The
treatments were 4 implemented N-levels applied as urea fertilizer that
equivalents to kg N/ha: 0; 50; 100; and 150, respectively, with five
replications applied resulting 20 experimental units. All experimental units
were arranged in according to the
method of Randomized Block Design (RBD). Observed attributes are; plant vertical
height, number of tillers/clump, leaf size (leaf-sheath and leaf-blade lengths, and leaf-blade width), and forage yields (fresh and dry-matter productions). Analysis of variance
was applied to examine the effect of the treatment on each of the considered parameters. Then, the Least Significant Difference (LSD) test was done to compare
between treatments on any plant attribute that significantly influenced by the treatment (P<0.05). The study results have shown that the
observed plant attributes have been significantly increased by increasing
levels of the fertilizer treatments, but plant height and leaf-sheath length
did not. These are shown by increasing the growth and production attributes from
the zero (0 kg N/ha) treatment to the highest applied nitrogen (equivalent to
150 kg N/ha), respectively: number of tillers (22.31 to 31.48 plans/clumps);
leaf-blade length (55.20 to 62.17 cm); and leaf-blade width (3.05 to 3.26 cm); and
forage production (22.52 to 38.36 tonnes fresh herbage/ha, and 3.51 to 6.57
tonnes dry-matter/ha). It is concluded, therefore, that this grass genotype is
positively responsive to nitrogen fertilizer in such experimental condition.
