ABSTRACT: Performance of popcorn was investigated
under manual tillage and no-tillage soil preparation and three
spacing patterns (60cm x20cm, 60cm x 30cm and 60cm x 40cm) in a
2 by 3 factorial experiment fitted into randomized
complete-block design and replicated three times. Data on growth
and yield characters were obtained and subjected to analysis of
variance. The results indicated that some form of reduced
tillage is indispensable for optimum grain yield of popcorn;
manually tilled treatment out yielded no-tillage treatment.
Spacing had significant effects on the growth and yield of
popcorn. Popcorn yield in the trials was better at a spacing of
60cm by 20cm than other spacing treatments. It is recommended
from the result obtained that popcorn should be planted on
manually tilled land and spaced at 60cm by 20cm for optimum
grain yield.

Abstract: The Sclerotia of Pleurotus
tuberregium (Sing) were grown on four different substrates
namely: humus soil, mixture of Sawdust and humus soil, sawdust
and shreds of the wood of Treculia
africana. The quantity and quality of the fruit bodies
produced were measured using the following parameters: number
of fruit bodies produced, height of fruit bodies, fresh weight,
dry weight, diameter of pileus and length of the stipe. Sawdust
which served as the control was better growth medium in terms
of length of stipe, number of fruit bodies and height of
mushroom. The fruit bodies from a mixture of sawdust and humus
soil were better in terms of fresh and dry weight while humus
soil alone produced fruit bodies with wider pileus diameter.
The wood shreds of Treculia
africana did not
support the growth of the mushroom. The Nutritional composition
of the sclerotium and fruit bodies from the different
substrates showed that at P
£ 0.05, mushroom produced from the
mixture of sawdust and humus soil has a significant difference
in its percentage ash content and percentage lipid content.
There was also significant difference in both percentage
protein content and percentage crude fibre from mushroom
produced from sawdust. Another significance was recorded from
the sclerotium in it percentage carbohydrate and percentage
energy value while mushroom produced from humus soil showed
significance in its percentage moisture content.

Abstract: Medicinal plants are important
elements of traditional medicine in virtually all cultures and
product promise a cheaper source for therapeutics, greater
accuracy than chemotherapeutic agents and a viable solution for
all
problems which groupers culture faces today. The control of
Trichodinaiasis and Aeromonus hydrophila in ponds of stocked
tilapia with any antiprotozoal and antibacterial agent at
present is evidently a cost. In addition, possibly leaves toxic
residues in tilapia and mortality. Also, affect for a short
times. For the previous reasons, the medicinal plants
instead. Garlic (Allium sativum) and sheh el-baathran as
optional medicinal plants to treat fish Trichodina sp and
Aeromonas hydrophila . 350 Tilapia O.niloticus (average
weight 100 ±20 g) derived from a private fish farm in Kafr El
Sheikh governorate infested with Trichodina sp, were kept in
cement ponds (3×8 meter) and sex diets were
formulated to contain different levels of Allium sativum
extract (1, 4 and 8g/kg diet) and sheh el- bathran extract (1,
3, and 4.5g/kg diet) added. The results showed that crude
extracts of either garlic or sheh el- baathran at 800 mg/l
significantly (P < 0.05) eliminated Trichodina sp and Aeromonas
hydrophila infections in tilapia. garlic and sheh el-
baathran will be used as an alternatives to chemicals to treat
of infected tilapia with Trichodina and Aeromonus
hydrophila.

Abstract: COX-2
inhibitors are a class of drugs which selectively inhibit
cox-2, an enzyme involved in inflammation pathway.
Prostaglandins induce inflammation, pain and fever. Aspirin
blocks the enzyme cyclooxygenase (COX-1,2) which is
involved in the ring closure and addition of O2 to arachidonic acid
converting to prostaglandins . The
present study was undertaken to analyze the docking efficacy of
aspirin with the target molecule (1IGX) and to assess the best
ligand for inhibiting COX and to analyze the docking programme by ARGUSLAB.
Substituting the –Cl ion in place of –OH group in
aspirin showed two hydrogen bonds with phenylalanine and
glutamine residues as its docking site where as substituting
the –Br ion showed two hydrogen bonds with Histidine and
glutamine residues as its docking site. The finding suggests
halogen substituted Aspirin to be a better ligand preferably
with Bromine. However clinical trials and laboratory
investigation will help in marketing the modified drug.

Abstract: The
study examines benefits of Human Resources Programmes to Community
Development Officers in Rivers
State, Nigeria.
A structured questionnaire was administered to 190 randomly
selected Community Development Officers in the study area.
Findings revealed Workshop, Seminar, in-service
training/on-the-job training, refresher courses/re-training
programmes, Orientation courses/induction programmes, Weekend
study/short courses, Symposium and Computer literacy as Human
resources programmes that community development officers
participate in. Also, findings revealed that the following
benefits have been derived from HRD programmes: Human resource
development (HRD) programmes have helped to improve skills and
competence in organizing community development programmes, HRD
programmes have provided opportunities to acquire new skills
and techniques for organizing community development programmes,
HRD programmes provided by Rivers State government has made
them better professionals or experts in community development,
enhanced computer literacy through computer training provided by
your employer. Based on the findings of the study it is
recommended that more HRD programmes be provided regularly for
community development officers in order to improve their skills
and competence. Also, study leave with pay should be encouraged
to update the knowledge of those who may have been employed
earlier without adequate requisite credentials. It is also
suggested that weekend and short courses be encouraged among
community development officers.

Abstract: Rwanda
harbors a great
diversity of wild orchids. This work provides an update
to the diversity, distribution and ornamental potential of the Volcanoes National Park orchids. A
total of 50 orchids species grouped in 23 genera have been
identified. In the park, orchids appeared to occur mostly in
the area extending from Mount Bisoke
to Gahinga. The park proved to be home to a number of orchid
species of floriculture merit with their brilliant and delicate
blooms such as Satyrium crassicaule,
Cynorkis kassneriana, Satyrium sacculatum and Habenaria praestans. Unfortunately,
the orchid diversity of the park has been subject to a number
of human-originated threats. Through this study, the issue of
an integrated effort of preservation which in part can be done
by domestication and ex-situ conservation through ornamental
horticulture was discussed.

ABSTRACT: Laggera pterodonta (DC.) Sch. Bip. aerial part was extracted successively with
hexane, ethyl acetate and methanol. The extracts were screened in vitro for activity against
standard strains microbes and clinical isolates. The zones of
inhibition, minimum inhibitory concentration (MIC), minimum
bactericidal concentration (MBC) and minimum fungicidal
concentration (MFC) were determined. The in vitro antimicrobial
screening revealed that the extract exhibited varying activity against different microbes
with zones of inhibition ranging from 14-32mm, MIC ranging from
1.25 - 5mg/ml, and MBC/MFC of 2.5-10mg/ml. The highest
activity was an MIC of 1.25 mg/ml and MBC of 2.5mg/ml. The
activities observed could be due to the presence of some of the
secondary metabolites like, alkaloids, tannins, sterols,
glycosides, saponins, terpenes and flavonoids present in the
plant. Isolation work to determine compound(s) responsible for
activities is ongoing.

Abstract: Molluscan
species were collected from specific stations of Narmada River from July 2009 to
June 2010. During the present investigation carried out, about
eight species of class gastropoda and eight species of class
pelecypoda were recorded through out the year. Among the
gastropoda group, Vivipara
bengalensis was most dominant followed by Bellamya bengalensis, Indoplanorbis, Unio species,
Thiara scabra, Pila globosa, Thiara lineata, and Thiara tuberculata.
Among pelecypoda the dominant species was Lymnaea acuminate, followed by Lymnea auricularia, Corbicula striatella,
Pissidium clarkeanum, Melanoides tuberculates, Musculium
indicum, Parreysia favidens, Corbicula striatella and Perreysia caerulea. Vivipara bengalensis and
Bellamya bengalensis
dominated the Molluscans fauna and are distributed from the
shore line to 3 m depth in all types of sediments. They were
found dead on the shore in large numbers during summer. Their
maximum density was recorded in summer and minimum in post
monsoon season.

Abstract: This
study is based on a survey of 36 randomly selected farmers in
the three agricultural zones of the state with high
concentration of vegetable farming using waste water.
Information obtained from the farmers was analyzed using basic
statistics and t-values evaluated using the ordinary least
squares multiple regression technique. A profit measure was
also used to evaluate the profit realized from waste water use
and non-waste water use, by applying with and without
principle. Results showed that waste water use has a negative
effect on vegetable crop production as can be seen from the
signs of the parameter estimate representing waste water. It
was also observed that people within the age bracket of 46 - 55
years engage most in vegetable farming, and they do this
because of the less tedious nature of the job. Some of the
vegetable farmers use waste water in addition to fresh water,
while others do so in order to take advantage of the nutrients
it contains. The study further showed that increased waste
water use reduces the farmers output and hence revenue. Given
the degree of adverse effects of waste water use in the state,
it is therefore imperative that prompt action be taken to curb
these effect as well as definite actions towards effective
waste water management.

Abstract- Aquatic
macro-invertebrates play significant role in responding to a
variety of environmental conditions of rivers and streams and
therefore may be used as bio-indicators for water quality
assessment. In the past, biological communities like plankton,
periphyton, microphytobenthos, macrozoobenthos, aquatic
macrophytes, fishes etc. have been used for the assessment of
water quality of rivers ,lakes and streams, but now the use of
benthic macro-invertebrates as bio-indicators is gaining
importance as these can be easily caught and seen with naked
eyes and the method is less costlier and less time consuming
compared to other methods given above. Oligochaeta Seven
species like Tubifex tubifex, Chaetogaster sp., Nais simplex,
Aeolosoma bengalensis, Dero limosa, Branchiura soverbyi,
Stylaria fossularis were indentified during the present study
HIRUDINEA Three species, Helobdella sp. Glossiphonia sp. and
HemicIepsis marginata of the family Glossiphonidae were
identified during the present study period. GASTROPODA
Altogether individuals of the three families Planorbidae.
Lymnaidae and Viviparidae were recorded among the class
Gastropoda during the study period. In the family Planorbidae
only one species Planorbis was identified during the study
period. Among family Lymnaidae three species were identified.
They were Limnaea auricularia , L. acumainata and other Limnaea sp. Limnaea
auricularia and L. acumainata family Viviparidae only three
species namely Vivipara bengalenis, V. oxytropsis and Bellamya
sp. were identified during the investigation period. BIVALVIA
(PELECYPODA) Only two species of Lamellidens was identified in
the family unionidae during the study period. Insecta Chironomus
phumosus, Strictochironomussp, Baetissp., Corixasp.,Berosus
sp., Hydaticus sp. Crustacea Apus (tadpole shrimp), Daphnia
(water flea) was identified during the study period. The
present studies deals with the population density and species
diversity of aquatic macro invertebrate fauna have been
discussed.

e-mail: dr_nundaeyo@yahoo.com
Abstract: A study was
conducted in 1995/96 to 1997/98 cropping seasons at Epemakinde,
a rainforest area of southwestern Nigeria to assess the effects
of different tillage practices viz: conventional (CT), minimum
(MT), traditional (TT) and zero (ZT) on the yields, cost of
production and economic returns to management of maize (Zea
mays) /cassava (Manihot esculenta) intercrop. A randomized complete block
design with three replicates was used. Results showed that grain yield
only differed significantly in 1998 with CT and ZT being lower
than both MT and TT by 2 and 25%, respectively. Average of maize across the
three years indicated that TT (3.15 t/ha) significantly out
yielded both CT and ZT by 16%.
Cassava fresh root yield differed significantly in 1998
with TT (44.72 t/ha) producing higher than other tillage
practices by 2-24% while MT (40.60 t/ha) yielded higher than
others by 3-19% in 1998 cropping season. The CT and MT treatments had
the highest cost of production and economic returns and
superseded ZT by 21% and 8%, respectively. This study has demonstrated
the necessity of some level of tillage with MT treatment being
the most desirable.

E-mail: azzaelgan@yahoo.com
Abstract: The reproductive characteristics and
stomach contents of the filefish Stephanolepis diaspros
in the Gulf of Suez were
investigated through samples collected from 2004 to 2007. The
overall sex ratio of males to females was estimated as1.00:
0.18, where females are represented in small sizes (8.0- 16.0
cm) while males largely outnumber females up to the length
interval 16.0- 26.0 cm. The monthly average values of gonad
weight percentages and monthly different maturity stages showed
that the species spawns during summer season with intensive
spawning in May. The length at first sexual maturity was
estimated at 9.5 cm for males and 8.5 cm for females. The diet
of file fish consisted of a wide variety of items, dominated by
Crustaceans and mollusks. Algae, Echinoderms and fish remains
were also demonstrated in the stomachs of the file fish.
Sponges, Hydra sp., foraminifera and Pryozoa were also preyed by
the file fish. The maximum feeding intensity was attained in
spring season, while the minimum feeding intensity was observed
during summer (June and September).

Abstract: Ten genotypes of rice (Oryza sativa
L.) including some lines
collected from the farmers fields in Abia, Ebonyi and Imo
States of South Eastern, Nigeria, were used
for the experiment. The seeds were grown in the early seasons
of 2006 and 2007 at the Teaching and Research farms of the
Federal University of Technology, Owerri and used for assessing
their yield and Physicochemical
characteristics. Moderate to high variation was observed
for all the characters studied. Number of tillers per stand
varied most having a coefficient of variation of 20% followed
by percentage fibre (18. 7%) indicating a scope for selection
of these traits among the lines evaluated. Conversely,
percentage amylose (1.9%), grain length (4. 4%) and percentage
protein (5 .4 %), had lower values for coefficient of variation
suggesting that the variation were more genetically similar in
these attributes. Heritability
in the broad sense estimates revealed that grain length
had the highest heritability (93. 2%) followed by number of
days to anthesis (90 .7%) while number of spikelets/ panicle
(32.3%) and number of tillers / stand (49.03%) were the least.
The physical characteristics of the grains divided the lines
investigated into long slender, long bold and medium bold sizes
and shapes. Among the lines however, Mass and Wita 4 combined
high numbers of tillers/ stand, high percentage fertile
spikelets and high number of seeds per secondary branch of
panicle and long slender grains. On the other hand, Sipi 692033
and NERICA 1 had higher percentage protein and amylose with
long grains.

temperature of 35oC and 25 oC
respectively during late season enhanced the attainment of days
to 50% flowering and 50% fruiting by 35days earlier in all the
accessions than the early season with 34 oC and 24
oC. Also the rainfall for the period between 50%
flowering and 50% fruiting was 464.9mm in the early season
whereas the corresponding value for late season was 97.2mm,
hence this could be said to have been responsible for over 50%
reduction in the fruit weight per plant across all the 31
accessions during early season due to flower abortion, stem
lodging and high fruits loses.
