Pengaruh Pemberian Molibdenum (Mo) terhadap Pertumbuhan dan Pr oduksi Kedelai
Abstract: The Mo is essential
for plants, molybdenum cofactor (Moco) forms active site ofall eukarotic Mo
enzymes. Nitrate reductase enzyme is available in all plants,which is needed to
change NO3- taken by plant to NH3. In legume, Mo is nitroge-nase enzyme
component, that is needed in changing N2 become NH3, hat is why Mois very
needed in N fixation process. With C, H, and O, sometimes S, NH3 formamino acid
whether or not containing S, amino enzyme, nucleate acid, chlorofil,alkaloite
and purin base. That is why Mo is very important in forming protein
andchlorofil. The research was conducted in green house of universitas Riau
Agricul-ture Faculty. Ultisol soil was taken from Rumbai Pesisir region, Pekanbaru
city in 0– 20 cm depth. The analysis of soil chemical characteristic before
conducting re-search was done in Balai Penelitian Tanah Bogor. The research was
arranged incomplete random design consisted of six treatment : 0, 200, 400,
600, 800 and 1000g NH4-molybdate/ha, each treatment was treated three times.
The aim of this re-search is to study the effects of application of
NH4-molydate to crop growth andSoybean yield. The result showed that aplication
of 600 g NH4- molybdate/ha haveimproved the crop growth and increased the
soybean yield by 65,61 % comparedto control.
