Abstract: |
This study was conducted to
investigate the impacts of water logging and salinity on
crop production in village Adina, District Swabi of Khyber
Pakhtunkhwa. Questionnaire survey was used for data
collection about underlying causes of water logging and
salinity in the area, comparative assessment of yield
production in water logged and non-water logged soil and
vulnerability of different crops to water logging and
salinity. Soil was also analyzed for pH and Electrical
Conductivity. Study findings indicated that yield of crops
was comparatively low approximately (88%) in water logged
and saline areas. The major causes contributing to water
logging and salinity were seepage from canals and Terbala
Dam (48%) and poor irrigation practices of farmers (28%).
Rice crop was resistant to water logging while maize and
wheat were most effected crops. Results of analysis
indicated that pH and electrical conductivity of water
logged soil samples was high. It is suggested on the basis
of results that modern scientific methods should be used for
irrigation and cultivation in the affected area. Salinity
Control and Reclamation Project (SCARP) was launched in the
area that proved effective but still there is a need to
upgrade the existing project to reclaim important
agricultural land. |

Abstract: |
District Shangla is located in
the Khyber Pakhtunkhwa province of Pakistan, in the
Himalayan mountain ranges and is unique for its diverse
flora. A detailed survey was conducted during 2013-14 to
explore economically important indigenous medicinal plants
species of district Shangla. Study was designed with the
purpose of providing baseline information on the use of
plant species in local system through surveys and field
visits. The economic potential of these species was
investigated by surveying the four most popular markets
Alpurai, Puran, Besham and Shahpur. A total number of 76
medicinal plant species were collected and identified from
four different sites of District Shangla. Among these 76
plant species 12 plants were shrubs, 52 plants were herbs,
11 were trees and one was fungus. There were 44 different
families, highest number of species (11) were belonging to
Lamiaceae followed by to Asteraceae (6 species) and then
Violaceae (5 species). Top ten economically most important
species, identified in the area were Morchellaesculenta,
Aconitum hetrophyllum, Dactylorhiza hatagirea, Podophyllum
emodi, Trillium govanianum, Viola canescens, Thymus linearis,
Thalictrum foliosum and Geranium wallichianum. Keeping in
view, the medicinal and market value, the plants can be used
for commercial level cultivation in order to suffice the
required amount and to conserve the natural resources. |

Abstract: |
A field experiment was
conducted during summer season June-September of the year
2015 in a demonstration farm in Mutaain South Jordan, to
investigate the effects of chemical fertilizer NPK
(15:15:15) at 150Kg/ha, chicken manure at rate of 20t/ha and
their combination on the productivity and growth parameters
of squash (cucurbita pepoL.). The parameters investigated in
the study were, fruit productivity (t/ha), fruit yield
(g/plant), fruit length(cm), plant, fruit number per plant,
average of leaves number per plant and plant height (cm).
The results showed that, all fertilizer treatments had
remarkable effect on all growth parameters and crop
productivity. The highest fruits production 2.3 t/ha was
achieved by the combination of NPK fertilizer and chicken
manure compared to 1.79t/ha produced by the control. The
combined use of NPK and chicken manure was also increased
the number of fruits per plant significantly at (p<0.05),
where the recorded value was 10 fruits/plant compared to 6.5
fruits/plant recorded by the control. |

Title: |

Abstract: |
Fusarium oxysporum f. sp.
vanillae is the causal agent of stem rot in vanilla
worldwide. In Mexico, this plant pathogen has been
identified by their morphological characteristics and ITS
sequence of rRNA, however, due to the complexity of the
taxonomy of the genus, it is considered necessary to confirm
this identity with the sequence of the EF-1α gene. The
methodologies reported for the amplification of this gene
are variable and do not show optimal results. In this study
it was proposed to adapt a protocol for genomic DNA
extraction and amplification of EF-1α gene for F. oxysporum
f. sp. vanillae. It was observed that the modification of
protocol developed for bacteria was more efficient that one
based on CTAB. A decrease in the concentrations of dNTP's
and primers also an increase in annealing temperature
regarding a protocol reported in the literature allowed to
obtain amplification products unique and good quality. Once
that was confirmed that strains belong to F. oxysporum,
sequences were deposited in GenBank. |

Abstract: |
Millet and cowpea
intercropping system, the most widespread in Niger has
enormous potential and can help boost smallholders’ farmer
productivity environment if proper techniques are applied.
In order to evaluate the effect of density and cowpea
genotypes on the growth and yield of millet and cowpea in
intercropping. An experiment was conducted in the field in
rainy season of 2015 in western Boki Nigerien. The
experimental design is a split plot with three replications.
Ten cowpea genotypes were grown in association with a single
variety of millet in two densities in the ratio line millet
intercropped with a cowpea line as density1 and line millet
two cowpea lines as density 2. Millet was sown at the same
density. Plant density and genotypes were not significantly
affected the growth of millet. Yield and its components have
not been affected either by the density nor the genotypes.
Increasing the cowpea plant density reduced yields of
millet. unlike cowpea which is the density 2 gave higher
yields. The yield and its components were significantly
affected by the cowpea genotypes. The success of this
culture system must rest mainly cowpea genotypes selection
and plant population. In light of our results is the density
2 giving high yields of cowpea seeds and stalks without
compromising productivity of millet which should be
encouraged. |

Abstract: |
In Côte d’Ivoire, oil palm
occupies a prominent position in agricultural production,
the economy, as well as the fats consumption. The country
seeks to double its production from here at the year 2020,
through improving the productivity of this culture. The
yield still remains low (about 18 tons/ha/year in industrial
plantations and only 9 to 10 tons/ha/year in village
plantations), even with the improved planting material in
the course of popularization whose the productivity is
estimated at over 25 tons/ha/year. Tests were installed in
the localities of La Mé and Ehania to contribute to
improving the productivity of oil palm through a comparative
study of the efficiency of potassium fertilization applied
in industrial and village plantations. The experiments were
conducted in randomized complete block of Fisher including 5
treatments and 4 repetitions. Treatments include 5 doses of
potash fertilizer (T1, T2, T3, T4, T5) respectively
corresponding to 1; 1.5; 2; 2.5; 3 kg of KCl/tree/year. The
results showed that the oil palm yields were progressively
improved following types of planting and growing locality by
different doses of potassium fertilizer applied. This
improvement was significantly higher on industrial
plantations and plantations of Ehania compared respectively
to village plantations and those of La Mé. The strict
adherence to farming itineraries combined with a reasoned
potassium fertilization allow better expression of the
potential of production of the new plant material of oil
palm, in the course of popularization. To this end, it must
be applied to small producers, monitoring of operating
technical itineraries (cultural practices and contribution
of inputs) as on industrial plantations. In this area, a
priority should also be given to the supply of potassium
fertilizer with optimum doses are defined by the practice of
foliar diagnostics leading to profitable oil palm
cultivation. |
