POLA PEMUPUKAN DAN ANALISA KANDUNGAN NITRAT PADA SAYUR BROKOLI ( Brassica oleracea cv. brocolli ) DI PERTANIAN DESA MERDEKA KECAMATAN MERDEKA KABUPATEN KARO TAHUN 2012
Abstract: Fertilization System
and Laboratory Analysis to the Content of Nitrate on Broccoli Vegetable
(Brassica oleracea cv. brocolli ) in the Agricultural of Desa Merdeka Kecamatan
Merdeka Kabupaten Karo 2012. Broccoli is a popular vegetable that many people
like very much. To have a good grow is demanded much more fertilizer.
Naturally, a green vegetable contained Nitrate. To supply fertilizer with more
and coutinuosly, resulted in the nature content in Broccoli going to rise up.
Nitrate comprising Nitrogen (N) and Oxygen (O). In human body, Nitrate
transfered into Nitrite and then got reacted with Hemoglobin forming
Methenoglonbine may cause miss oxygen
(hypoxsemia). In blood, it cause Nitrosamid or stomach cancer. On babies well
known as “blues babies”. The objective of this study is to determine the
requirement in applying fertilizer for Broccoli vegetable comprising of
frequency in fertilizing, type and dosage of fertilizer, the method applying
the fertilizer, space of plant for fertilizer, as well as to know total content
of Nitrate on Broccoli vegetable. This study adopted descriptive survey
research with spectroguan Nova Go method. In this case is this case is to count
the content of Nitrate compared to standard content of nitrate refers to the
ADI ( Acceptable Daily Intake )of the European Commission’s Scientific
Committee For Food 1995 namely 3,65 mg/kg. The result of study showed that
all sample as Broccoli vegetable
fulfilled the requirement an not exceeding 50 mg/litre. Total fertilizer to
apply also not exceeding as standard as determined for chemical fertilizer 1.4
ton per hectare and compost 2 ton per hectare. Frequency of fertilizing not
exceeding standard. Noted 6 farmers applied fertilizer on morning and its plant distance far fertilizer
less than 10-25 cm. It is concluded the content of Nitrate on Broccoli
vegetable is not exceeding threshold and the pattern of planting by farmers is not different from
standard, it is suggested to everybody be carefull to consume the broccoli
