Abstract: |
This study is to
determine the comparison of bird diversity and density
between mangroves and oil palm plantation and its vicinity
in the state of Selangor, Malaysia. The data was collected
from two regions; Teluk Panglima Garang-Pulau Carey and
Banting-Jenjarom. To determine the composition, diversity
and density of resident bird communities, bird surveys were
conducted using the Point Count technique at each study
sites from October 2012 to May 2013. 4702 individuals were
detected representing 108 species and 42 families from the
surveys. The results show that species varied considerably
in their use of habitat, and also responded differently in
the same habitat in different regions. The oil palm
plantation has also demonstrated the lowest species richness
and absolute abundance of bird species in both sites. This
study clearly shows that the undisturbed area; for this case
mangrove is of critical importance for long-term survival of
a great number of species. |

Abstract: |
The vase life of
Lisianthus (Eustoma grandiflorum L.) cut flowers is
relatively short because of some post-harvest problems.
Thus, the purpose of this study was to evaluate the efficacy
of ascorbic acid (AsA) in extending the vase life of
Lisianthus cut flowers. Ascorbic acid is a natural acid and
an antioxidant compound which stabilize cell membrane and
proteins. Continuous treatment of ascorbic acid at 0, 50,
100 and 200 mg l-1 was administered to Lisianthus flowers.
The longest vase life of cut flowers (15.50 days) was
observed in flowers treated with 200 mg l-1 of ascorbic
acid. This treatment increased cut vase life seven days
longer that the control treatment. The maximum solution
uptake (4.133 ml g-1 F.W.) was calculated in 200 mg l-1
ascorbic acid. The highest dry matter (21.55%) and loss of
fresh weight (9.761 g) were obtained in 200 mg l-1 ascorbic
acid, too. The results of this study showed that ascorbic
acid (vitamin C), as a natural anti-oxidant, plays an
important role in prolong of cut Lisianthus flowers when it
is applied at suitable concentration. |

Abstract: |
Cotton is an important
cash crop. In developing countries like Pakistan, cotton is
a major source of economics to many farmers. The soils of
Pakistan are generally low in organic matter, firstly
because of arid climate resulting in a rapid decomposition
of organic matter and secondly because very little organic
matter is added to the soil. Soil nutrients deficiency
fulfilled by the application of phosphorus as well as
nitrogenous fertilizers. Experiment was carried out in the
wire house of Botany Department, Ghazi University Dera Ghazi
Khan. 60 earthen pots were used to test the vegetative
growth parameters of two cotton cultivars. i.e. BT 886 and
BT 905 of cotton species having 5 replicates and 3
treatments for each cultivar. Two-way ANOVA was carried out
to determine the differences among treatment groups and
growth and development variables of cotton by using a
statistical software MINITAB version 14. From this trial
experiment it was concluded that the application of
synthetic fertilizers showed highly significant difference
at the different levels of vegetative growth of two cotton
cultivars than the application of animal manure. Among the
cultivars, Cultivar 2 i.e. BT 905 showed maximum growth at
various harvesting intervals under the significantly
increase the treatments levels than the cultivar 1 i.e. BT
886. The concluded annotations of this trail were that the
Synthetic fertilizers were more appropriate to obtain the
good quality and quantity of fiber crops than the animal
manure. |

Title: |
Socio-economic factors
affecting income generating activities of poor women
enterprises in Zalingei- Sudan |

Abstract: |
Women are 70% of the
world’s poor and 70% of agricultural labor in developing
countries. Women’s enterprises tend to be relatively small,
have informal structures, flexibility, low capital needs,
modest educational requirements, high labor intensity, and
depend on local raw materials. Due to all mentioned above
people are living in low income level and economic status.
The main objective of this research is to investigate the
linkages between rural finance and rural women and socio-
economic characteristics affecting Income generating
activities. A well-structured pre-tested questionnaire used
to collect the data. The age, employee and additional income
were significant at 0.01, 0.05 and 0.1% level of
significances for the model implying that the respondents
are depending in their income for their age, employee, in
the others and additional income received as remittance from
their relatives. |

Title: |

vase life, solution uptake and chlorophyll content of cut
lisianthus (eustoma grandiflorum l.) flowers |

Abstract: |
Lisianthus (Eustoma
grandiflorum L.) is an ornamental plant which contains one
of the world’s top cut flowers. Vase life of cut Lisianthus
flower is relatively short. Citric acid is an organic
compound and a natural acid. Different concentrations of
citric acid were used as preservative solutions aiming to
extend the vase life of cut Lisianthus flowers. These
flowers; at optimum developmental stage was treated with a
vase solution containing citric acid at concentrations of 0,
50, 100 and 200 mg l-1. Longevity of cut Lisianthus flowers
was determined on the basis of wilting and chlorophyll
retention. Cut Lisianthus was kept at room temperature
(20±2°C) under normal day light and natural ventilation. The
greatest longevity of vase life (15.37 days) was related to
200 mg l-1citric acid. This treatment increased cut vase
life more than six days longer that the control treatment.
The maximum solution uptake (4.82 ml g-1 F.W.) was
calculated in 200 mg l-1citric acid. The highest total
chlorophyll content (8.40 mg g-1 F.W.) was obtained in 100
mg l-1 citric acid. The present study concludes that it
would be possible to use solutions containing citric acid to
maximize extending the vase life of cut Lisianthus flowers. |
