Sweet potato, a perspective crop for the sandy soil area in Romania
No full textDue to the low natural fertility and climatic conditions characterized by excessive heat and insufficient precipitation, the
sandy soils area in southern Oltenia can be characterized as a disadvantaged agricultural area, with farmers having a
small variety of crops to ensure the exploitation of the soil in profitable conditions. In the context of climate change, in
order to obtain high, safe and stable productions, it is necessary to choose the range of species and plant varieties with
high adaptability to the climatic and soil conditions, in this context, Research-Development Station for Plants Culture
on Sands Dăbuleni conducting research on the adaptability and profitability of sweet potato culture. Considering that in
the tropical and subtropical regions completely replace the potato, F.A.O. mentions sweet potatoes on the 7th place in
the world among agricultural crops. Currently, this culture is less known in Romania. With the increase in the import of
vegetables, the interest of Romanian consumers for this species of tropical origin has increased. Taking into account
these considerations, the researches aimed at establishing the technology of sweet potato cultivation on sandy soils and
the biological and biochemical peculiarities of this species. The obtained results were similar to those in the literature,
the differences being due to the studied genotypes and to the climatic conditions of the crop year. It is a drought
resistant species with vigorous growth and high productivity (20-40 t / ha). Sweet potato is a species of perspective for
Romanian vegetable growing, with special nutritional qualities and economically profitable

The material was harvested at intervals between 8 and 17 days, with a total of 5 harvests.The species most frequently collected were Opatrum sabulosum L., Otiorrhynchus raucus F., cupreus Carabus L., Pseudophonus rufipes, Harpalus aeneus Amara aenea F.şi Payk
Researches on the control of the common reed (Phragmites australis (Cav.) Trin. Ex Steud.) in areas of the irrigation or drainage channels
Get PDFThe research was undertaken during 2016 and 2017 in the pedoclimatic conditions at the farm SC Agroprod Seaca SA
(aluviosol type soil, with a humus content of 4.2%), refers to the possibility of controlling the invasive species
Phragmites australis (common reed) in the draining systems from the area. Tt was studied the influence of different
methods of common reed control, in corn field and different methods applyed on from the area, (still in experiment for
the next year), by comparing the use of glyphosate, with other Phragmites australis (common reed) control methods. In
treated area (dry drainage canals), herbicide efficacy was evaluated 30 and 60 days after treatment considering a scale
from 0 to 100% for control of common reed (in 2016-2017). In autumn of 2016, the common reed was burned or cut,
the effectiveness of these methods, applied, on flood protection dams, in 2016, was appreciated on 11 April 2017,
together with the efficacy assessment after application, at different time, in 2017
Present aspects of the systematic cadastral works conducted on cadastral sectors for the registration of real estates in the land register
No full textThe topographic measurements and the technical cadastral documents drawn up in time in Romania included several
distinct stages. The main differences between them consisted in the society’s development requirements at that particular
moment and the measuring technologies used. Law on Cadastre and Real Estate Advertising no.7/1996, with the
subsequent modifications and completions, created the context for drawing up and implementing the unitary cadastre and
land register system. This system includes 3,181 administrative - territorial units as follows: 103 municipalities, 217 cities
and 2,861 communes, the latter one with 12,957 villages. At the same time, it was started the National Cadastre and Land
Registration Program, estimated to be conducted between 2015 and 2023. The main objective of the program consists in
performing systematic cadastral works considering the cadastral sectors in the administrative territorial units, so they can
be registered in the land register. The cadastral documents drawn up on cadastral sectors indicate the measured surface as
well as the real property right over the real estates. According to the present administrative - territorial organization of
Suceava County, its 8,553 km2
include 114 administrative – territorial units, of which: 5 municipalities, 11 cities and 98
communes, the latter ones including 379 villages. Our case study tried to point out the real technical and legal situation of
two cadastral sectors situated in the unincorporated area of Bilca commune, Suceava County. The two cadastral sectors
that were identified and analysed cover 14.5134 ha (cadastral number 243) and 10.0668 ha (cadastral number 254),
respectively. The limits of the real estates from the two cadastral sectors mentioned resulted from field measurements and
their identification with the legal owners. The limits of the cadastral sectors were indicated on the basic plan sheet, scale
1:5000, nomenclature L-35-04-B-a-3-III and the control area 540.9816 ha

The influence of tillage systems on soil physical properties for winter wheat crop (Triticum aestivum L.) at Ezăreni Research Station
No full textTillage systems have influence on soil physical properties and have different consequences for plant growth and
development. In particular, tillage systems affect yields.
The experiment was conducted at the Didactic Station of the University of Agricultural Sciences, Iasi – Ezareni Farm
on a cambic mesocalcaric regraded chernozem between 2016 and 2017 for winter wheat crop.
We investigated two variants of soil tillage systems: no-till and conventional tillage regarding soil moisture and bulk
density, during vegetation and harvest.
In order to determine the main physical properties such as bulk density, soil samples were collected from 10 to 10 cm
down to 40 cm depth: 0-10 cm, 10-20 cm, 20-30 cm and 30-40 cm. For soil moisture the samples were collected from 6
layers as follows 0-10 cm, 10-20 cm, 20-30 cm, 30-50 cm, 50-70 cm, 70-90 cm.
The bulk density values revealed that it increased in both tillage systems and depths.
The mean bulk density showed that it registered the lowest values in no-till variant during vegetation (1.36 g/cm3
) while
the highest value was registered in conventional tillage at harvest (1.55 g/cm3
).
Soil moisture showed differences along depth, growth stages and tillage systems, with higher values for the no-till
variant in all periods except of the harvest, where the value was higher in conventional system compared on no-till
(20.36% and 18.89% respectively)

Optimizarea parametrilor de biosorbţie pentru reţinerea ionilor de Cu(II) pe biomasă de alge marine roşii şi verzi
No full textMarine algae are an important biomass resource because of the many properties they have in solving various environmental problems such as the ability to decontaminate wastewater, soil decontamination, soil fertilization, etc. Heavy metal pollution is a problem for the environment. The development of industrial activities has led to increased emissions of heavy metals into the environment, with negative consequences for soils, plants, rivers and waters. Therefore, it is necessary to find appropriate methods that should be environmentally friendly in removing metal ions in a more efficient and inexpensive way. In this paper we optimized the biosorption parameters (pH, initial concentration and contact time) for the retention of Cu (II) ions on algae biomass, using two types of marine algae: a red one Callithamnion corymbosum sp. and a green one -Ulva lactuca sp. from aqueous solution
