Studies to evaluate selenium (Se) supplementation through various application methods for its enrichment in bread wheat (Triticum aestivum L.) were conducted in the Seed Science Laboratory and Agronomic Research Area, Department of Agronomy, University of Agriculture, Faisalabad, Pakistan. Initially, two laboratory studies were conducted to optimize the rate of Se supplementation for seed priming and seed coating of two wheat cultivars Shafaq-2006 and Lasani-2008. Laboratory experiments were carried out in a completely randomized design in factorial arrangements and replicated thrice. In an initial field study, the impact of exogenous Se supplementation by various methods on the enrichment of two local bread wheat cultivars was undertaken while in a second experiment, grain enrichment potential through foliage applied Se on wheat cv. Lasani-2008 was investigated. Both field experiments were carried out in randomized complete block design in a factorial arrangement having a net plot size of 2.7× 6.0 m with three and four replications respectively. Results of the laboratory priming experiment revealed that seeds primed in 0.125 mM and 1.25 mM Se priming solution gave a significantly improved stand establishment and seedling growth rate as exhibited by a substantial reduction in the time to undertake 50% emergence (T50) and the mean emergence time (MET) as compared to other treatments. In the second laboratory trial, coating of 1 kg of wheat seed with either 1.5 or 1.0 g Se considerably improved the early emergence, which in turn resulted in a healthy seedling stand establishment and better growth of seedlings of both wheat cultivars studied. In the first field study, Se supplementation by foliage feeding (100 g ha-1 or 50 g ha-1) significantly improved spike length, number of spikelets spike-1, number of grains spike-1, the number of productive tillers m- 2, 1000-grain weight, biological yield, grain yield and harvest index of both wheat cultivars and during both years of the study. However, non-significant variation in plant height for both varieties was recorded with Se nutrition. Maximum Se enrichment was observed in grains of wheat cv. Lasani- 2008 when treated with foliar feeding of 100 g Se ha-1. Lasani-2008 showed better potential for accumulation of Se in grains as compared to Shafaq-2006. Results of the second field study revealed that different sources of Se supplementation, applied at different growth stages, significantly affected the growth and yield of wheat. Maximum grain yield was attained with foliar spray of sodium selenate at booting stage. In contrast, Se foliage sprays applied at anthesis (flowering) caused significantly higher accumulation of Se in wheat grains as compared to all other treatments. In first field trial, Se application through seed priming, at the rate of 0.125 mM showed the maximum net benefit while in the second field study; maximum net benefit was obtained with the Se foliar spray at the booting stage of growth.

عبدالحمید، حکیم
’’ملک و ملت کا مسیحا نہیں رہا‘‘
بالآخر وہی ہوا جس کا کھٹکا مہینوں سے لگا تھا اور اس مسیحا نفس نے اپنی جان جان آفریں کو سپرد کردی، جس کی مسیحائی سے لاکھوں نے زندگی پائی تھی، حق یہ ہے کہ حکیم عبدالحمید کی وفات پر بھی وہی الفاظ دہرائے جائیں جو مسیح الملک حکیم محمد اجمل خاں کی وفات پر مولانا سید سلیمان ندویؒ نے تحریر فرمائے تھے حکیم صاحب کی وفات خاندان کا ماتم نہیں، دلی کا ماتم نہیں، قوم کا ماتم ہے، فضل و کمال کا ماتم ہے، اخلاق و شرافت کا ماتم ہے، سنجیدگی و متانت کا ماتم ہے، عقل و رزانت کا ماتم ہے، آزادی و حریت کا ماتم ہے، اخلاق و ایثار کا ماتم ہے، ہندوستان اور مسلمانان ہند کے طالع و بخت کا ماتم ہے۔
؂ مرثیہ ہے ایک کا اور نوحہ ساری قوم کا
حکیم عبدالحمید کا دائرہ فیض و خدمت بہت وسیع تھا، ان سے پورا ملک مستفیض ہورہا تھا۔ ہمدرد کی دوائیں سکہ رائج الوقت کی طرح گھر گھر پھیلی ہوئی ہیں اس لیے آج سب ہی اس محسن اعظم کی جدائی پر اشک بار اور ماتم کناں ہیں۔
؂ عمت فواضلہ فعم مصابہ
حکیم صاحب جس بدنصیب ملت کے فرد فرید تھے اس میں بڑا قحط الرجال ہے، وہ تنہا اپنی ذات سے ایک انجمن، ایک ادارہ، ایک جماعت اور ایک قوم تھے، ان جیسے پیکر صدق و اخلاص اور سراپا خدمت و عمل کا اٹھ جانا عجب سانحہ اور ملت اسلامیہ کا زبردست خسارہ ہے، سمجھ میں نہیں آتا کہ اس کی تلافی کیسے ہوگی اور اس غم کا مداوا کیا ہوگا۔ بلا شبہ وہ اس عہد کے مسیح الملک، ابن سینا اور رازی تھے۔

الأمر ومعانيه فى القر آن الكريم: دراسة دلالية نحوية

As all of know that start of the revelation of Holy Qur’ān started with imperative form of the verb as it is ended with like that. This shows that the imperative mood is one of the most magnificent topics of an Arabic language، particularly in the Qur’ān context. According to the opinion of the major scholars، both the commencement and conclusion of the Holy Qur’ān were in the imperative mood. Thereupon، the scholars of Arabic language took a keen interest in study of meanings of the imperative mood whether literal or figurative. From the abovementioned point of view the following article attempts to study the meanings of imperative mood، whether they are literal or figurative، and also it endeavors along with its connotations in the light of what is stated in the Holy Qur’ān and Sunn’āh as well as in the sources of Arabic language، to lead those who recite the Holy Qur’ān to the right way، guide them to the truth and to help them in understanding of the secret meanings of Qur’ān.

An Analysis of Socio-Economic Factors Affecting Forest Area in Pakistan With Special Reference to Nwfp 1972-2000

This study was an attempt to analyze the socio-economic factors affecting forest area in Pakistan. Every year different areas are afforested and regenerated. Policies and programs are prepared to increase the forest area up to national requirements but there is no significant increase in the area rather fast deforestation is taking place. Forest communities play a significant role in the use and depletion of these resources. The study highlighted the assumptions about some macro economic variables, which are generally considered as key socio-economic factors that cause deforestation and depletion of forests and tested the hypothesis in order to show the impact of these factors on forest area in Pakistan. In order to achieve the objectives of the study and to test the hypotheses the followed methodology has two aspects; one, consulting the forest communities in forest rich areas of the province and second, analyzing the macro economic data of different socio economic factors that have impacts on the forest area of the country. For the first aspect two forest rich areas in NWFP; District Abbottabad and District Mansehra have been selected. The socio economic conditions of these areas have been discussed and analyzed. The priorities and practices of forest communities in the use of different resources have been checked. For the second aspect the study analyzed time series data of some of the socio-economic factors of Pakistan for example agriculture production, cultivated area, livestock and human population, the consumption of fuel wood substitutes etc. Taking the forest area of NWFP and forest area of Pakistan as a whole then checked the results of these socio- economic factors. For the analysis multiple regression technique was applied on the time series data from 1972-2000. The results of the econometric models were then compared with the primary information collected from the two districts of NWFP; District Abbottabad and District Mansehra. These results were further analyzed by comparing them with earlier studies conducted in the same field. iiThe results of the primary data showed that most of the firewood and timber is extracted illegally and there is no official record or even a rough estimation of the total quantity illegally extracted. The most responsible figure as mentioned by the locals also includes Forest Department, which is a part of timber mafia. Forest department has no arrangement for forest fires; it is the locals who extinguish it by using local practices. The study area has not received real benefit of gas provision by the government in the country because these facilities are not yet extended to their areas and alternate sources are not enough. Both the study areas are suffering from some problems, which are contributing to deforestation, for example common property, lack of interest and cooperation of Forest Department with locals, lack of follow up of forestry programs especially started by foreign agencies etc. In both the areas there is no increase in animals so livestock population is not the prime threat. Human population has increased but they are either migrating to other areas or opting for service sector. In both the areas people have very little knowledge about government policies and programs. The results of the primary information showed some valuable facts about forest land conversion for other purposes, about Forest Department, the role of government and non-government organizations, about forest fires and about timber mafia in the study area. The results of the regression models obtained from the time series macro economic data showed that some of the socio-economic factors of the country that are generally considered as the most responsible factors for the depletion of forests such as increase in human and livestock population are not the important factors contributing towards deforestation in Pakistan but some others like cultivation, construction, consumption of timber and agriculture production are playing their due role towards deforestation. The study further showed that increase in the consumption of firewood substitutes could not significantly improve the situation. The analysis further showed the extent of effect of different variables on the forest areas. The recommendations of the study have given more emphasis to control the land use practices especially controlling land conversion for other purposes, proper demarcation of iiiforest boundaries in Abbottabad and Mansehra districts to save from conversion and misuse, on regular basis the involvement of locals in plantation and giving incentives in cash and kind for plantation, provision of alternate energy resources in the study area especially to hill side forest communities, and proper follow up of the programs already launched in forestry sector to maintain the confidence of the locals. Further, since cultivation and construction activities are the main threat found in the study so more focused attention is needed in this regard and the general policy for addressing these problems would not work. To build up forestry data base is the prime requirement. The macro economic time series data of Pakistan is not accommodating illegal timber. So constructing an estimated time series data for actual fire wood and timber consumption including illegal extraction in Pakistan would be the future task based on the results of the present study that would give more robust results out of the present research.
