Abstract: |
Nigella Sativa is an annual
garden flowering plant, belonging to the buttercup family
Ranunculaceae. It is native to southern Europe, North Africa
and Southwest Asia, where it is found on neglected, damp
patches of land. Black cumin seed contains oil; protein;
alkaloids such as nigellicimine and nigellidine; kinons such
as timokinon and saponin; and Volatile essence. It is used
as a homeopathy cure for respiratory conditions such as
asthma, cough, bronchitis, etc. Tissue culture is one of the
techniques which are used in biotechnology and plant
breeding and it is among the most powerful materials for
propagation and breeding. Accordingly, a study was conducted
in the tissue culture laboratory of the Laboratory Complex,
Islamic Azad University, Science and Research Branch,
Tehran, to investigate the effect of different hormones
densities on internode and hypocotyl regarding different
characteristics like the number of shoots and roots, their
lengths, their fresh and dry weights, the fresh and dry
weights of callus and its volume in March 2015. Hormone
treatments included BA with the densities of 0.5, 1, and 2
5M, NNA with the densities of 0, 0.5, and 1 5M, and SA with
the densities of 0 and 1 5M. The results indicated that the
maximum number of shoots and roots, length of roots, dry
weight of roots, fresh weight of shoots, fresh weight of
callus and its volume were observed in the hormone density
of BA=2, NAA=1, and SA=1. In addition, the longest shoot was
observed in the hormone density of BA=0.5, NAA=0, and SA=0.
No statistically significant interaction was identified
between the hormone treatment and the dry weight of callus,
the fresh weight of root, and the dry weight of shoot. Also,
there wasn t any statistically significant interaction
between hormone treatment and the sampling places on the
characteristics on the probability level of 5%. |

Abstract: |
Elemental analysis of the
roots, stems, leaves, and fruits of tomato was performed
using scanning electron microscopy equipped with energy
dispersive X-ray spectroscopy (SEM-EDS) and Atomic
absorption spectroscopy (AAS). irrigation water of tomato
plants were found free from heavy toxic metals, (Zn, Cd, Co,
Cr, Mn), but have traces of Cu and Pb. Traces of Zn, Cu, Cr,
Pb, and Mn were detected in the soil. EDS analysis showed
that toxic heavy metals Pb, Co, Cr, Mn, Ti, Zn, and Cu were
detected and accumulated in the roots system of tomato, only
Pb tranbsfered from the root to stems. Fe found to be
accumulated in all parts of tomato plant. |

Abstract: |
Allocation of resources is one
of the principal concepts in economics and assessment of is
the most important index of optimal allocation. Considering
shortage production agents and the necessity for optimal use
of these agents, assessment comes into play as a key basis
of development projects with its great role in extentasian
and development of projects especially in developing
countries. Decision-making based of the gains of plans in
relation with the performed costs constitutes the basis of
the economic assessment of a project. Therefore, in every
producing area, conductance of financial and economic
estimations is crucial in order to investigate, justify, and
prioritize different activities. The sericulture development
and side silk industries projects were established in the
Shaft town, of Guilan Province by the Corporation of
Sericulture of Guilan Province in 2013. These projects
includ 4 phans (Cultivation of modified mulberry seedling,
Construction of sericulture site, Construction of
silk-pulling site, Weaving silk texture and local clothes).
This research has dealt with the assessment of the mentioned
plans. The aim of this investigation is to evaluate the
extendibility plans of sericulture and spindling workshops
through assessment indexs including the Payback Period,
Payback Period Reverse, Acconting Rate of Return, Net
Present Value, Internal Rate of Return, The Benefits to cost
ratio and The profitability Index. The obtained results
indicated that all of the three considered scenarios
(development of a silkworm rearing site, development of a
spindling workshop, and development of both sites) were
economically justifiable. |

Abstract: |
In Indonesia, soybean was a
strategic food commodities, as the sixth soybean producer
country of the world, until now, Indonesia still importing a
big amount of soybean from the other countries, it makes
Indonesia reach the ninth position of soybean importer
country of the world, until 2019, the estimation of the
deficit is up to 204%.The objectives of this studied was
analyzing variables and indicators that can increase the
amount of soybean production. This research was conducted by
surveys, interviews and questionnaire at the relevant
agencies were Department of Agriculture food crops, farmers'
groups combined, Group Farming and individual national
soybean farmers of Jember and Banyuwangi, the secondary data
was obtained from the previous research s road map, the
previous research related documents and the public web. The
researchused9variabelswith37indicators.The data was analyzed
by SWOT . The result showed that the right strategy was the
Aggressive strategy that are: 1). Eight items weakness, 2).
Realising sixteen items opportunities, 3). Eight items
maintain strength and 4). Eliminating / change two items
threat. |
