Abstract: |
Production and
reproduction performance of Jersey cattle at Cattle Breeding and Dairy
Farm, Harichand, Charsadda, NWFP during 1993 to 2003 was investigated.
Effect of season and year of calving on milk yield and reproduction were
studied. Average age at puberty was 748.71 ± 22.5 days and a coefficient
of variation of 21.87%. Average lactation yield was 1663.15 ± 70.25
liters and a coefficient of variation of 29.23%. The average lactation
daily milk yield was 5.3 ± 0.117 liters, with a coefficient of variation
of 15.28%. Number of services per conception was 1.5 ± 0.152 and a
coefficient of variation of 73.02%. Recording system at the farm needs
to be improved and if possible, the data should be electronically
managed. |

Abstract: |
Domestic sewage
contains important nutrients for the growth of plants and is used for
aquaculture in several parts of the world. The campus of Indian
Institute of Technology (IIT), Kharagpur generates 14.29 lakh liters day-1
of sewage. Only 17% of the total sewage is going to the existing ponds
while the remaining 83% is wasted due to leakage in the underground
drainage system. There is a possibility of pollution of soil and ground
water around the IIT, Kharagpur campus. A study was initiated to assess
the present situation and to design a sewage-fed aquaculture farm on the
campus. The area was physically surveyed, soil samples and
meteorological data collected and analysed. Based on the collected
information, a model of sewage-fed aquaculture farm was designed. This
would utilize the nutrients present in the sewage and would reduce the
risk of pollution of soil and ground water in the area. The data
collected from the proposed sewage treatment aquaculture farm show that
the desired dissolved oxygen level (> 5 mg/l) was achieved on 4th day
from 1 mg/l, COD concentration (< 50 mg/l) on 6th day from 350 mg/l, TSS
(80 mg/l) on 5th day from 350 mg/l, BOD concentration (<20 mg/l) on 6th
day from 180 mg/l and ammonium-nitrogen concentration (0.2-3 mg/l) was
achieved on 5th day. Economic analysis of the model sewage-fed
aquaculture farm shows that there will be an annual profit of Rs.
766,014/- on an annual investment of Rs. 677,986/- (excluding cost of
land and sewage water). The farm will produce 35,000kg of fish per year
and will also generate employment of 2,545 men-days per year. |

Abstract: |
The experiment was
conducted at Malakandher Research Farm, NWFP Agricultural University,
Peshawar during summer 2000. It was replicated 4 times in RCB Design
with split plot arrangement having plot size of 3 x 3.5m. The maize
hybrids included in the experiment were Pioneer 3025, Cargill 707,
Cargill 922 and Baber while plant to plant spacing was 15, 25, 35 and
45cm. Emergence m-², number of cobs per plant, cob weight, grain yield
(kg ha-1) and harvest index were significantly affected by
hybrids. Hybrid Pioneer had Emergence m-² (10) significantly higher
number of cobs plant-1 (1.14), cob weight (324g), grain yield
(3275kg ha-1) and higher harvest index (24) as compared with
other hybrids. Various spacing had significantly affected emergence m-²,
cobs/m², grains cob m-1, cob weight and biological yield
while the effect on other parameters was non-significant. Spacing of
15cm had significantly more emergence m-² (10), number of cob per m²
(10), lower grains cob-1 (343), lowest cob weight (227g) but
higher biological yield (15691kg ha-1). Interaction of hybrid
Pioneer and 25cm give highest grain yield ha-1. |

Abstract: |
A study to investigate
hard tick (Ixodid) infestation and genera identification in 30 different
herds in randomly selected 15 villages of Frontier Region Peshawar was
carried out during August 2003 through February 2004. Ticks were
identified for their genera, in Parasitology Laboratory, Veterinary
Research Institute, Peshawar. The effect of month, age, status of body
condition, post treatment effect of acaricides, housing and grazing
systems on tick infestation was recorded. Out of 1279 farm animals
studied, 255 cattle, 97 buffalo, 273 sheep, 544 goat and 110 donkeys
were studied for tick infestation. About 13.37 % of the total observed
farm animals were found tick infested with highest infestation in cattle
(20.4%) followed by sheep (12.8%), goat (12.1%), buffalo (11.3%) and
donkey (6.4%). The most commonly prevalent ticks were belonging to genus
Boophilus (46.1%) followed by Hyalomma (31.25%), Rhipicephalus (17.93%)
and Amblyomma (4.61%). Tick infestation was higher in late summer and
lower in winter. The effect of age, status of body condition and post
treatment effect of acaricides was found non-significant. |

fatua) densities and proportions on yield and yield components of wheat |

Abstract: |
To study the effect of
wild oats densities and proportions on yield and yield components of
wheat, field trials were conducted at Malakandher Research Farm, NWFP
Agricultural University, Peshawar. The experiment was laid out in
Randomize Complete Block (RCB) design with split plot arrangement. Four
seed rates of wheat viz.100, 130,160 and 190kg ha-1 were
assigned to main plots, while wild oats densities 0, 5, 10, 15, 20, 25
and 30 seeds m-2 were kept into sub-plots. Data were recorded
on number of spikes m-2, spike length (cm), grains spike-1
, 1000 grain weight (g), tiller wild oat-1, number of seeds per tiller of
wild oat and grain yield (kg ha-1) . Statistical analysis of
the data showed that most of the parameters were statistically affected
by wild oats densities and seed rates. Maximum number of spikes m-2
(281.9), spike length (9.33cm), number of grains spike-1
(50.0), 1000-grain weight (30.26) and were recorded in wheat monoculture
(0 wild oat density plot). Seed rate of 160 kg ha-1 had
significantly higher spikes m-2 (283.4), spike length
(8.58cm), 1000-grain weight (30.87g) and grain yield. Thus a seed rate
of 160kg ha-1 was recommended for suppression of wild oats
population in wheat crop. The regression analysis also predicted lowest
competition of wild oats in wheat seeded at 160kg ha-1.
