Pemberian Limbah Padat (Sludge) Kelapa Sawit Dan Fungi Mikoriza Arbuskula (Fma) Terhadap Pertumbuhan Dan Produksi Kacang Hijau (Vigna Radiata L.) Varietas Vima 4
This study aims to determine the interaction effect between solid oil palm waste
(sludge) and Arbuscular Mycorrhizal Fungi (AMF) along with its best dose
calculation in supporting green bean’s growth and production. The research was
conducted experimentally using two factors Completely Randomized Design
(CRD) for four months (April to July 2019) in an experimental field of Riau
University’s Agriculture Faculty. Factor one is the sludge dose consisting of four
treatment levels (0 kg.plot-1, 1.7 kg.plot-1, 3.4 kg.plot-1, and 5.1 kg.plot-1), while
factor two is the AMF dose consisting of four treatment levels as well (0 g.plant-1,
5 g.plant-1, 7.5 g.plant-1, and 10 g.plant-1). The observed parameters were initial
and final soil chemistry analysis, root nodules percentage (%), mycorrhizal
infection effectivity (%), plants height (cm), amount of productive branches (fruit),
flowering days (DAP), harvest days (DAP), seeds per pod (grain), weight of one
hundred seeds (g), and seeds weight per plant (g). The data were analyzed using
variance and Honestly Significant Difference (HSD) test at 5% level. The result
showed that the application of solid oil palm waste (sludge) had a significant
impact on effective root nodules percentage, amount of productive branches,
flowering days, seeds per pod, weight of one hundred seeds, and seeds weight per
plant, while AMF dosing into soil had the same impact plus the effectivity of
mycorrhizal infection. Furthermore, the interaction between solid oil palm waste
(sludge) and Arbuscular Mycorrhizal Fungi (AMF) occured in the parameters of
effective root nodules percentage and seeds per pod.
Key words: green beans, solid oil palm waste, sludge, arbuscular mycorrhizal
