Abstract: |
A study on the effect of
poultry and cattle manures on the growth and yield of okra (Abelmoschus
esculentus L.) was carried out in the transitional zone
of Ghana in 2008 and 2009 in a randomized complete block
design experiment with three replicates. The treatments
were; 350 kg NPK ha-1, 8t Poultry Manure ha-1,
12t Cow dung Manure ha-1, 175 kg NPK + 4t Poultry
Manure ha-1, 175 kg NPK + 6t Cow dung Manure ha-1and
No treatment of manure (control). The combined treatments of
175 kg NPK + 4t Poultry Manure ha-1 and 175 kg
NPK + 6t Cow dung Manure ha-1 produced higher
levels of the growth and yield parameters than the rest of
the treatments in both seasons. The 175 kg NPK + 4t Poultry
Manure ha-1recorded the highest Figures which
were not significantly (P=0.05) different from the Figures
of the 175 kg NPK + 6t Cow dung Manure ha-1
treatment. The combined treatments were found to be
economically profitable. The treatment combination of 175 kg
NPK + 4t Poultry Manure ha-1 was more superior in
the areas assessed. |

Abstract: |
Land use planning based on land resource
evaluation and spatial orientation of planning as part of
GIS may ensures appropriate land allocation in order to
achieve sustainable agriculture. The combination of some
land resource evaluation can provide final results on
rational land allocation and land utilization based on land
capability and suitability. Land capability evaluation (LCE)
and land suitability evaluation (LSE) approach rooted from
USDA and FAO was used in this study to allocated arable land
as agricultural developed areas and determine prime
commodities spatially. The principle of limiting condition
was used for LCE to define land class and determine land
availabitiy for agriculture. While, for LSE, procedure of
matching between land quality/characteristics and crop
requirement will be scored according to limitation method
and class criteria of land suitability in order to define
the most suitable crop considered as prime commodity. The
objective of this study was to determine prime commodities
at developed areas on the basis of information of land
resources at regional scale of 250, 000. With GIS
application, the result of evaluation were then integrated
into spatial information as basic consideration for
agricultural land use planning and further spatial analysis
for agricultural land allocation as well. This study was
conducted in Central Kalimantan province with total areas of
15, 451, 287 hectares in order to support policy of
Indonesian Government for agricultural development
especially for spatial agricultural land use planning. The
results of this studies showed that based on LCE approach,
almost 61.94% of total areas (9, 571, 231 hectares) is
arable land indicating that lands geographicaly have an
opportunity to be developed. While based on LSE approach and
GIS application, there are 3 (three) prime commodities
including their geographical distribution pattern that
suitable to be developed in Central Kalimantan involving
wetland rubber (7, 355, 390
hectares), rice (2,
141, 539 hectares), and oil
palm (1, 722, 806 hectares). Appropriate programs in
the scoupe of land use planning can then be formulated to
support agricultural development at certain areas. |

Title: |
Characteristics of fly ash and use ability in Vietnam |

|
Abstract: |
Physically fly ash occurs as very fine
particles and having low to medium bulk density. Fly ash has
a vast potential for use in agriculture as an amendment
especially due its physical condition which are conducive
for plant growth as well as due to the presence of Ca, Mg, K
and P in it. Fly ash of Pha Lai thermal power plant contains
high contents of SiO2 and Al2O3
so it has colloidal properties like puzzolant. Fly ash can
be used for agricultural and environmental purposes. |

Title: |
Genetic
gains from within-breed selection for egg production traits
in a Nigerian local chicken |

Abstract: |
This study aimed at estimating
the genetic gain in egg production traits in a Nigerian
local chicken ecotype (LE) population subjected to
short-term (first ninety days of lay) selection over three
generations. A selected and control line were established
and monitored for the following egg production traits - Body
Weight at First Egg (BWFE), Egg Weight (EW) and Egg Number
(EN). Hens were selected based on a selection index
constructed in each generation using the three traits as the
selection criteria traits. A total number of 360, 769 and
1033 records were used in generations zero, one and two
respectively. Selection differential and genetic response
due to selection were estimated. A cumulative selection
differential of 269.38g, 1.58g and 3.88 eggs were obtained
for BWFE, EW and EN respectively. Selection response for
each trait increased over the generations. Realized response
per generation was estimated to be 94.22g, 0.84g and
4.85eggs for BWFE, EW and EN respectively. The simultaneous
inclusion of BWFE, EW, and EN in a selection index generally
improved the performance of selected birds over the
generations in the LE. |

Title: |
Influence
of weed interference duration on the yield and viscosity of
okra (Abelmoschus Esculentus (L) Moench) varieties in
south-eastern Nigeria |

Abstract: |
Field studies were
carried out at the Teaching and Research Farm of the Federal
University of Technology, Owerri,
Nigeria to determine the influence of weed interference on
the yield and viscosity of three okra (Abelmoschus
esculentus (L.) Moench) varieties. Three
varieties of okra (NHAe47-4, Lady’s finger and V35)
were weeded using five weeding regimes (weedy check,
unweeded till 5 weeks after sowing (WAS), weeding once each
at 3 WAS and 4 WAS and weed free). The treatment
combinations were laid out in a randomized complete block
design with three replications. NHAe47-4 was shorter than
the other varieties but produced larger leaves and more
flowers than the rest in both years. Higher fruit yields
(23.63t ha-1 in 2007 and 22.96t ha-1
in 2008) were produced by NHAe47-4 among the weeded plots
which were not significantly different from the weed free
plots (2420 and 22.13t ha-1 in 2007 and 2008
respectively). Better weed control was achieved from
NHAe47-4 (80.65 and 76.97% in 2007 and 2008 respectively)
comparable with the weed free plots. The viscosity of okra
from the weeded plots is in the decreasing order of NHAe47-4
< V35 < Lady’s finger in 2007 and 2008. The result showed
that among the weeded plots okra variety NHAe47-4 weeded at
3 WAS was more viscous than the others and will therefore be
of greater acceptability to the food consumers. |

Abstract: |
This
study used the wastewater from the fish pond for
hydroponics. It was combined the benefits in terms of crop
production and wastewater treatment. The assumption of this
research expected that plants could use the nutrients that
contained in the wastewater. The
wastewater was treated using the
aerobic technology
with hydroponic reactor on
hydraulic retention times (HRTs) 1, 3,
5, and 7 days. The
collected wastewater samples at inlet and outlet of
hydroponic reactor. The parameters were analyzed with the
standard methods. The parameters were
temperature, pH, DO,
TKN, TP, TK, TS, SS, VSS, TDS, and COD.
They were used to evaluate the performance of the wastewater
treatment with a hydroponic. The results of parameter
analysis showed that the pH values of effluent were in the
ranges of 7.33-8.0 with the temperature of 27ºC-29ºC. These
ranges of pH and temperature value have litter effects or
did not effect in significant to the performance of
hydroponic. The total reductions on
1, 3, 5, and 7 days of
hydraulics retention times of TDS, COD, TKN, TP and TK
ranged from 20.4% to 70.0%, 52.0% to 79.0%, 12.23% to
50.56%, 8.33% to 33.33%, and 0% to 44.44%, respectively. The
result of this study showed that hydroponic could treat
wastewater from fish pond. The result also showed the
increasing of dissolved oxygen in wastewater of
1, 3, 5, and 7 days of
hydraulics retention times in DO ranged from 33.33% to
66.67%. The results obtained in these investigations show
that it was possible to recover nutritious substances from
fish processing wastewater by hydroponics. Hydroponic
production systems have potential for the treatment and
reuse of wastewater in intensive aquaculture systems. |
