PERTUMBUHAN VEGETATIF DUA VARIETAS JAGUN G PADA TANAH GAMBUT YANG DIBERI LIMBAH PULP & PAPER

Sari

Vegetative growth performance of two varieties of maize by  pulp and paper waste application has been studied  in  peat  soils  using  Factorial  Completely  Randomized  Design  in  biological  garden,  faculty  of education  and  teacher training,  Riau  University.  The  experiments were arrange by  factorial 2 x 5   and three replications. First factor was two maize varieties i.e. Arjuna and Bisi-2. Second factor was Pulp and Paper waste taken from Riau Pulp and Paper Industry. Rate of application were 0,  15, 20, 25, and 30 gr kg 1peat soils. Plant height, leaf length, leaf wide and plant dry weight were measured. Data analyzed by using ANAVA  dan  Duncan’s Multiple Range Test at 5% level of signification.  The results  shows that plant height and leaf length has significance difference between two maize varieties, but not for leaf wide and dry weight. There were no significant interactions effects for all parameters observed. We conclude that the varieties of Arjuna more tolerance and adaptive to  peat soil.

Key words : pulp and paper industrial waste, maize tolerance, vegetative growth
