PENGARUH PEMBERIAN ABU VULKANIK TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KEDELAI (Glycine max L. Merril)
Abstract: The purpose of this
research is determining the effect of volcanic ash and get a dose of the best
on the growth and production of soybean. Research has been conducted in the
experimental field of the Agriculture Faculty, University of Riau from April to
July 2015. The research used randomized design group, consisted of 5 treatments
and 4 replications, so that there are 20 experimental units. The treatment is
dose of volcanic ash 0 tons/ha, 7.5 tons/ha, 15 tons/ha, 22.5 tons/ha and 30
tons/ha. Parameters that observed were height plant, number of branches,
flowering age, harvesting age, number of total pods per plant, number of full
pods per plant , weight seeds per m2 and weight of 100 seeds. Data were
analyzed by analysis of variance, then
continued with further test with Duncan's new multiple range test at 5%. The
results of research showed that giving of volcanic ash significantly take
effect to height plant, number of branches, flowering age, harvesting age,
number of total pods per plant, number of full pods per plant and weight seeds
per m2 but the effect is not significant to the weight of 100 seeds of soybean
plants. Provision of volcanic ash of 22.5 ton/ha is the best treatment against
the parameters of a number of branches (9,35 branches), flowering age (31
days), harvesting age (88,5 days), number of total pods per plant (201,9 pods),
number of full pods per plant (174,68 pods) and weight seeds per m2(476,61 g or
4,289 ton/ha).
