Abstract: |
Vegetative
propagation studies were carried out at Maseno University,
Kenya in the year 2004 and 2005 using stem cuttings on
three endangered indigenous tree species namely Asystasia
schimperi, carissa edulis and Toddalia asiatica to test the
effect of IBA on rooting of the stem cuttings of these plant
species. Juvenile stem cuttings of these plant species were
dipped in different concentrations of auxin (indole Butyric
Acid (IBA) of 0, 100 ppm, 200ppm, 400ppm and 500ppm.
Completely, randomized design (C.R.D) was used and the
treatments replicated three times in a non mist
polypropagator. The treated cuttings were planted in
polythene pots. The duration of the experiment was four
months. Data taken were plant height number of leaves and
number of rooted cuttings every 2 weeks. Data was subjected
to analysis of variance (ANOVA) and means separated by L.S.D
at 5% significance level. The results showed that hormone
concentration, species and date of sampling affected the
number of rooted plants, plant height and number of leaves
Asystasia schimperi had the best rooting and subsequent
plant growth followed by Carissa edulis and lastly Toddalia
asiatica. It can be concluded that Asystasia schimperi and
Toddalia asiatica can be propagated by stem cuttings easily
hence farmers can cultivate them.

Abstract: |
The
objective of the study was to evaluate the growth and dry
matter production of components of sorghum/cowpea intercrop
at
Kano
,
Nigeria
. The treatments consisted of thirty cowpea genotypes
differing in maturity periods and growth habits which were
intercropped with local sorghum in 1:1 or single alternate
row arrangement. The results revealed that plant height,
number of days to maturity and dry matter of sorghum was not
affected by cowpea genotype. The percent plant count after
emergence and at harvest of the genotypes was not affected
by sorghum intercropping; the mean values were 91% and 86%,
respectively. The early maturing genotypes flowered (36-39
days) and matured (70-75 days) earlier than the medium
genotypes which took (36-39 days) and (70-75 days) to flower
and mature, respectively. The late maturing genotypes
took longer time to flower (42-81 days) and some matured in
79-80 days while Kanannado and IT95K-1133-2 which flowered,
did not attain maturity due possibly to insect damage.
Generally the early maturing genotypes had narrower canopy
spread (65-97 cm) than the medium and late maturing
genotypes most of which were at par with IT96D-738 having
the widest width (165 cm). Plant height of cowpea was not
affected by cowpea genotype. Medium maturing genotypes
IT96D-740 recorded the highest dry matter but which was at
par with few other medium and late maturing genotypes while
lower values were recorded by the early maturing group. |

Abstract: |
Physical
and chemical quality appraisal of different commercial brand
yoghurts available in the Lahore market was studied during
the year 2006 and study included yoghurt samples of
Guormet’s, Moon Dairies, Nestle and Nirala sweets to
analyse for acidity, pH, protein, total solids, solids not
fat, and carbohydrate/lactose. It was recorded that Nestle
yoghurt had 1.00±0.01% acidity, 5.44±0.01 pH, 4.00±0.06%
protein, 15.84±0.10% total solids, 13.08±0.11% solids not
fat, and 8.47±0.12% carbohydrate/lactose. Yoghurt of
Gourmet’s had 1.19±0.01% acidity, 5.50±0.01 pH, 3.73±0.08%
protein, 11.35±0.09% TS, 10.86±0.09% SNF, and 6.27±0.10%
carbohydrate/lactose. Moon Dairies yoghurt had 1.20±0.02%
acidity, 5.43±0.01 pH, 3.85±0.08% protein, 11.53±0.14%
TS, 11.00±0.13% SNF, and 6.35±0.14% carbohydrate/lactose.
Nirala yoghurt contained 1.15±0.01% acidity, 5.42±0.01 pH,
4.16±0.06% protein, 12.36±0.09% TS, 11.82±0.09% SNF, and
6.93±0.11% carbohydrate/lactose. Nestle yoghurt was found
to be superior in term of syneresis as compared to the
yoghurt being marketed by Gourmet’s , Moon Dairies, and
Nirala sweets. |

Abstract: |
A
laboratory study was conducted to evaluate the influence of
seed priming techniques on germination and early growth of
tow maize inbred lines which were include of B73 and MO17.
Seeds were hydroprimed for 12, 24, 36 and 48 h, osmoprimed
in urea solution and in solution of polyethylene
glycol-6000(PEG- 6000) for 96 h (water potential -1.2MPa).
Priming techniques affected seed germination and early
growth of both inbred lines. Hydropriming resulted in lower
time taken to 50% germination and higher germination index,
vigor index and final germination percentage in both
genotypes. Maximum invigoration was observed in seeds
hydroprimed for 36 h as indicated by higher germination
rate, radical length. Conversely, for most germination
parameters osmoprimed seeds behaved similar to or even poor
than that of control. |

Abstract: |
This study
evaluated the effects of two edible fruits: banana and
pawpaw fruits on the growth performance of the African giant
land snail (Archachatina marginata). The study was conducted
in Asaba,
Delta State
,
Nigeria
in 2007. The snails were fed on both the unripe and ripe
banana and pawpaw fruits, which served as the treatments
over a period of 12 weeks. Results showed that significant
differences (P ≤ 0.05) existed in the snails (in terms
of weight, length and width of the snail shell as well as
the dry matter intake) fed on both the unripe and ripe
fruits. On the whole, Archachatina marginata fed on ripe
banana fruits performed significantly (P ≤ 0.05)
better when compared with those fed on the unripe banana,
and the unripe and ripe pawpaw. This study has demonstrated
that different edible fruits have significant effects on the
growth performance of Archachatina marginata with the snails
performing better when fed on ripe banana fruits. Ripe
banana fruits are therefore, recommended to snail farmers in
the rural areas of
Nigeria
for optimum growth of A. marginata. |

Abstract: |
An
experiment to evaluate the performance of some improved
cowpea genotypes intercropped with sorghum in single
alternate row arrangement was conducted at Minjibir,
Kano
,
Nigeria
. 30 cowpea genotypes differing in maturity and growth
habits and local sorghum variety were used. The results
indicated that a medium maturing genotype, IT95K-222-14
produced the highest grain yield while Danila, a medium
maturing improve local cultivar, recorded the highest fodder
yield. Some late maturing, spreading cowpea genotypes
produced little or no grain yield. The yield and yield
components of sorghum were not affected by cowpea genotype.
Analysis of the intercrop productivity (LER) demonstrated
that intercropping sorghum with IT95K-222-14 gave the
highest value (1.88). Based on high grain and fodder yields,
intercrop productivity Danila, IT90K-277-2, IT95K-1091-3,
IT96D-759, IT96D-666 and IT95K-222-14 could be selected for
improving the productivity of sorghum/cowpea mixture in the
Sudan
savanna. |

bunch yield among the D x T inter-population progenies of
the NIFOR second cycle oil palm (elaeis guineensis jacq.)

Abstract: |
The
performance of 51 D x T inter-population progenies derived
from the second cycle modified reciprocal recurrent
selection (RRS) breeding programme of Nigerian Institute for
Oil Palm Research (NIFOR) was evaluated to estimate
variability among the progenies and to identify the best
performing progenies for introduction into the locality
where the experiment was conducted. The trials were laid out
in a randomized complete block design. Data was collected on
number of harvested bunches (BN), single bunch weight (SBW),
and fresh fruit bunch (FFB) yield. Analysis of variance
(ANOVA) showed significant difference in all the traits
analyzed among the progenies. Each trait was also analyzed
using F-LSD. The results showed that De10, Dut6, Du15, Du12
(BN); Det6, Det1, and Du16 (SBW) and Det5 and Du10 (FFB)
were quite outstanding and thus, recommended for the
production of genetically superior progenies as new
commercial planting materials.
