The cabbage crops is one of the most important spectrum vegetable
plants, this is demonstrated by the large area planted and yields obtained. The
quality and quantity of white cabbage depend by variety, technology, fertilizer

INTRODUCTION White cabbage is widespread in Romania (15% of the vegetable), being cultivated from early spring until late autumn, using adapted cultivation in this sense (Stan and Munteanu, 2001). White cabbage is resistant specie to low                                                            1 University of Agricultural Sciences and Veterinary Medicine of Iasi, Romania 2 Vasile Adamachi”, College of Agricultural and Food Industry, Iasi, Romania LUCRĂRI ŞTIINłIFICE SERIA HORTICULTURĂ, vol. 58(2) / 2015, U.S.A.M.V. IAŞI 88 temperatures, which gives a good adaptation to climatic conditions and the possibility of extending cultivation conveer. Early cabbage crop in the NE region of Romania can establish successful during 1-7 April in each year, were obtained production from 29.89 t/ha up to 31.01 t/ha, for a crop density of 47,619 pl./ha (Sabareanu-Stoleru, 2010). According to the weather conditions of every year, planting period can increase or decrease obtained production. For other areas of Romania such Transylvania, at a density of 71,500 pl./ha, in the conventional system can achieve an average production of between 52-56 t/ha (Csok, 2009). The cultivar for establishing the crop can also have a major role in achieving high productions (Indrea et al., 2012). In the cabbage crop system, the cultivar has a decisive influence on production, and the economic efficiency of crop. If in conventional crop be carried out studies on fertilizer influence on production if they are relatively few organic farming and worth studying because it prevents contamination production. The differentiated fertilization in organic agriculture has positive influence on pest control (Stoleru et al., 2012) MATERIAL AND METHOD The experiment with early cabbage crop was carried out in an experimental plot at UASVM Iasi, during 2014. The experimental crop was established in 7 April 2014, by seedlings of 45 days, with a distance design of 70 x 30 cm (N= 47°11'34,07" E= 27°32'59,63"). Seedlings were been produce in a greenhouse, according with specific literature (Stan and Munteanu, 2001; Indrea et al., 2012). The soil from the stationary is a mold chambic chernozem, easy antropic, whit the following physicochemical properties, in the substrate of 0-60 cm: clay 32 %, ph=7,11, EC=252.3 µS/cm2, CaCO3=1.03%, OM=28.23 mg/kg, C/N = 5,20, N=4.53 g/kg, P=106.66 ppm, and CEC = 20.9 meq/100g. The biological material was used the Bourbone F1, recommended for early open field. To achieve its purpose, treatments were applied fertilizers in organic farming systems organic and conventional as follows: Orgevit® = 1300 kg/ha (applied in five stages, the first stage in 20 April and the following 10 in 10 days), Nutrifine®=1100 kg/ha (like as Orgevit®) and Micoseed®=75 kg/ha (applied in three stages, the first stage in 20 April and the following 10 in 10 days, that the treatment 4 and 5 was used Nutryaction®=5 l/ha) Micoseed® It is a fertilizer based on microorganisms, particularly based Glomus sp.  Nutrifine® is a synthetic chemical complex like as NPK 20-20-20. Orgevit® is an organic fertilizer (100%) from chicken manure applied as drops. The total yield and dynamic of production, according with fertilization schemes, was carried out by weigh the heads, for each harvest.

IAŞI 89  Fig.1  - Bourbone cultivar  The principle of humidity determination is based to loss of the drying oven at a temperature of 102°C, until a constant mass. The loss will be calculated as a percentage relative to the initial mass of the sample (Butnariu and Butu, 2014). Determination of heavy metals in vegetables is by dry mineralization. This consists in the destruction by carbonization and incineration (450-500°C) oven sample; ash being thus passed by dissolving in dilute hydrochloric acidan (Butnariu and Butu, 2014). The analyses of the heavy metals in cabbage have been made at the UASVM Iasi and UASVMB Timisoara. The dates collected have been statistical analyzed by one-way analysis of variance (ANOVA) and least significant differences (LSD) at 5%, 1% and 0.1% confidence levels for production. For the contaminants, the statistical significance were carried, compared with maximum accepted limit (MAL). RESULTS AND DISCUSSIONS Production results from early white cabbage In 2014, early white cabbage production ranged from 43.36 t/ha to 69.37 t/ha. In all experimental versions, the production was higher to the control un-fertilized. In the version biological fertilized with microorganisms, total production was the biggest is considered positive very significant.

Results on nitrate and nitrite content on white cabbage  The nitrites content ranged from 0.34 mg/kg in control up to 0.72 mg/kg in the version organic fertilized. The nitrate content ranged from 48.11 mg/kg in control up to 162.14 mg/kg in version fertilized with Nutrifine®. From the data obtained on fertilization regime on the content of nitrites and nitrates, we can say that regardless of the amount of fertilizer used and the type of early cabbage does not exceed the maximum acceptable limits, according with scientifically literature (Butnariu and Butu, 2014; Stoleru et al., 2014).                    0100200Bourbone x Nutrifi neBourbone x MicoseedBourbone x OrgevitBourbone x Martor0,5 0,56 0,72 0,34162,1498,7650,8 48,11Nitrites NaNO2 LMA 15-25 mg/kgNitrates KNO3 LMA 2500-4000 mg/kg Fig.2 -  The content of nitrites and nitrates in the white cabbage (mg/kg) LUCRĂRI ŞTIINłIFICE SERIA HORTICULTURĂ, vol. 58(2) / 2015, U.S.A.M.V. IAŞI 91  The influence of fertilization on the content of heavy metals in cabbage  The results on the influence of fertilization on heavy metal content are presented in Tabel 2. The values obtained for the heavy metals of each variant were compared with the MAL. The content of Cr range from 55 to 67 mg/kg, which shows that each version was exceeded MAL. Cu content varied from 31 to 37 mg/kg, which highlights that regardless of fertilization regime, the content of this element is not influenced.  The Pb element varied in the term of large limits, from 26 mg/kg in the biological version up to 52 mg in Control. In this version has been recorded and who is overcoming MAL who is 50 mg/kg. Zn content rage from 118 mg/kg in chemical version up to 155 mg/kg.

Regarding fertilization regime used in experimental version that regardless of the amount used has not influenced the content of nitrates and nitrites. In most samples, the MAL for heavy metals was not exceeded. Values higher than the MAL were recorded for version control. The presence of chemical contaminants in most versions, maintaining the support for monitoring investigations in order to protect human health. REFERENCES 1.
