Author (s):

Bashir Ahmad, Sirzamin Khan, Abdul Manan and Abdullah

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.

Title:

Biological treatment of domestic wastewater for aquaculture

Author (s):

Bansal A. K., A. Mitra, R. P. Arora, Trilok Gupta and B.S.M. Singhvi

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.

Title:

Effect of plant population on maize hybrids

Author (s):

Sikandar Azam, Murad Ali, Mohammad Amin, Shahida Bibi and Muhammad Arif

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-, 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- (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-, cobs/m, 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- (10), number of cob per m (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.

Title:

Prevalence and identification of Ixodid tick genera in Frontier Region Peshawar

Author (s):

Abdul Manan, Zabita Khan, Bashir Ahmad and Abdullah

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.

Title:

Effect of wild oats (Avena fatua) densities and proportions on yield and yield components of wheat

Author (s):

Ijaz Ahamd Khan, Gul Hassan, Ihsanullah and Iftikhar Alam Khattak

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.
