KUALITAS KIMIA DAN KANDUNGAN KLOROFIL TANAMAN ALFALFA (Medicago sativa L.) DENGAN LAMA PENYINARAN DAN DOSIS DOLOMIT YANG BERBEDA PADA TANAH REGOSOL
Abstract: This study aimed to
analyze the quality of chemical and chlorophyll content of alfalfa plants with
lenght of irradiation and dose of dolomite on the regosol soil. The experiment
was conducted implemented in Greenhouse Laboratory Forage and Pasture Faculty
of Animal Sciences University of Gadjah Mada, from May to September 2015. This
study used a Completely Randomized Design (CRD) 3 x 3 factorial design with two
factors treatments and four replications. The first factor is the dose of
dolomite (D) with 3 treatment (D0 = without dolomite, D1 = dolomite 6 t/hectare
or 90 g/polybag and D2= dolomite 12 t/hectare or 180 g/polybag). The second
factor is the length of irradiation (C) with 3 treatments (C0 = irradiating 12
hours, C1 = irradiating 14 hours and C2 = irradiating 16 hours). Data were
statistically analyzed using analysis of variance and significant results
continued with Duncan test at 5% level.Parameters measured were the proximate
analysis (dry matter, organic matter, crude protein, crude fiber, crude fat,
ash) and alfalfa chlorophyll content. The results showed that there was no significant
interaction effect between lenght of irradiation and dose of dolomite treatment
to the dry matter content, organic matter, crude protein, crude fiber, crude
fat, ash and alfalfa chlorophyll content. The treatment lenght of irradiation
are significant (P<0,05) of the organic matter content and ash content of
alfalfa. Dose of dolomite treatment was not significant on all parameters of
the study. The results showed that the treatment and dosage of radiation are
dolomite not significant on the production of plant fresh weight, dry weight of
plants, dry matter content, organic matter, crude protein, crude fiber, crude
fat, ash and content alfalfa chlorophyll. No interaction between treatment and
dosage of radiation are dolomite which significantly affect production plant
fresh weight, dry weight of plants, dry matter content, organic matter, crude
protein, crude fiber, crude fat, ash and alfalfa chlorophyll content.
