Climate change and its impact on crop productivity is a burning issue of the day .according to predictions of international panel on climate change (IPCC) and Pakistan Meteorological Department (PMD) these changes are taking place very rapidly on global level and affecting crop productivity. Their predictions are based on long term past climate data analysis with the help of general circulation models (GCMS).The aim of present study was to calibrate and validate CSM-Crop-Grow Cotton Model in DSSAT V 4.0.2. to simulate development, growth, and yield of cotton (Gossypium hirsutum L) under increased CO 2 concentration, elevated temperatures and varying rainfall scenarios. For these purpose field trials at three locations were conducted with two sowing dates, four cotton cultivars and four nitrogen levels with split-split plot design having three replications during year 2005 and 2006. The data on phenology, growth and yield were recorded and used for model calibration during 2005 (Genetic co-efficient of four cotton cultivars were determined).The model was then validated with independent set of data collected during year 2006 with same set of coefficient, long term past historic climate data of three locations (1974-2006), soil and crop management data used as input data for model and environmental modification sub menu of seasonal tool selected various climate change scenarios viz current i-e no change in environment. Elevated temperatures of + 0.9 O C and 1.8 O C, increased concentrations of CO 2 from 360 ppm to 550 ppm with no change in rainfall and increased / decreased 3% , 6% levels of rainfall expected in 2025 & 2050. The results indicated that model successfully simulated 80-90 % crop phenology and growth and 90-98 % yield accurately at various sites and can be used as reliable agronomic tool for strategy management in future. The elevated CO 2 levels would effect cotton crop growth and yield positively on all locations. Climate change analysis indicated strong influence of temperature on cotton production in Punjab, Pakistan. The yield will be substantially decreased with increasing temperature 1.8 O C and the effect was more severe at xviiilocations like Sahiwal. Increasing or decreasing 6% rainfall would affect cotton growth and yield negatively and drastic yield reductions were observed from the current. Selection of suitable cultivar, changing sowing time and nitrogen application are helpful in mitigation of adverse effects of changed climate of 2025-2050. Dominance analysis of different planting dates and cultivars at various locations suggested that 60 days early sowing of cotton crop from current at Faisalabad and Sahiwal with cultivar SLH-284, N applied @ 200 kg ha -1 is the best choice under changed climate scenarios (2050) whereas cultivar CIM -506 with nitrogen rate of 200 kg ha -1 out yielded all other cultivars when sown 15 days late from current at Multan location under changed climate scenario of 2050.
محمد یوسف صدیقی افسوس ہے اِنھیں دنوں ہمارے فاضل اورلائق دوست جناب یوسف صاحب صدیقی بھی ہم سے جدا ہوگئے، مرحوم انگریزی اخبار ریڈینس (اب ممنوع) کے اڈیٹر تھے۔ علی گڑھ یونیورسٹی کے گریجویٹ تھے،انگریزی اوراردو دونوں میں تحریر وتقریر کی قدرت تھی۔بڑے ہوش و گوش اور سمجھ بوجھ کے انسان تھے۔ صبرو استقلال اورخلوص اُن کا شعار تھا، مجلسِ مشاورت کے جنرل سکریٹری تھے،جماعت ِ اسلامی (اب ممنوع) کے ہائی کمانڈ میں شامل ہونے کے باعث متعدد بار قیدو بند کی تکالیف سے دوچار ہوئے ،لیکن پائے استقامت میں کبھی جنبش نہیں ہوئی،جووقت پڑا اسے ہنسی خوشی انگیزکرلیا۔ریڈینس کے ایڈیٹر کی حیثیت سے عرب ملکوں اورخصوصاً سعودیہ عرب میں اُن کا بڑا وقار و اعتبارتھا چنانچہ وہاں کی متعدد کانفرنسوں میں مدعو کی حیثیت سے شریک ہوئے۔ گھر کے بہت خوش حال اورصاحبِ املاک وجائداد تھے۔ عمر اسّی کے لگ بھگ ہوگی، اس کے باوجود گھر کا عیش وآرام چھوڑ کرجماعتی کاز کی خاطر دلّی میں غربت اور بے آرامی کی زندگی بسرکرتے رہے۔ اپنے وطن ٹونک میں تھے کہ وہاں سے بیوی کے ڈاکٹری معائنہ کی غرض سے جے پور آئے، ابھی ڈاکٹری معائنہ مکمل نہیں ہوا تھا کہ خود انہیں پیغامِ اجل آپہنچا۔ بڑی خوبیوں کے نہایت شریف اور باوضع انسان تھے۔ اللٰھُمَّ اغْفِرْلَہٗ وَارحمہ۔ [مئی۱۹۷۶ء]
Although several studies have investigated the contribution of Muslim women about their lives and works in large corpus of the ḥadīth sciences until now, but much are needed to be explored. Doubtlessly 'Amrah bint 'Abd al-Raḥmān had contributed to the large corpus of the ḥadīth sciences and also the core of Islamic knowledge parallel to her male counterparts. By highlighting her efforts for learning and her struggle for transmission of fundamental text, reveals how a female successor acquired exemplary reputations in her era. Particularly, her rich insight, deep knowledge in ḥadīth sciences and exemplary piety attracted students and placed parallel to her male counterparts in Islamic knowledge of her time. In sum, this study not merely sheds light upon the prolific contribution of an eminent female successor 'Amrah bint 'Abd al-Raḥmān in ḥadīth narrations, but argues that these scholarly females should be given more credit for being interacting educators and not just transmitters. Doubtlewssly, the study would be helpful to revise our understandings of Islamic knowledge during early period of Islam regarding gendered dynamics and their great contribution to dissemination and transmission of classical text and Islamic knowledge.
Geometric Function Theory on comprehensive spectrum deals with the geometric properties of analytic functions. In the study of analytic functions, image domains are of prime importance. Analytic functions are categorized into different classes on the basis of geometry of image domains. The core objective of present research is to study some applications of the convolution operator in Geometric Function Theory. We define some new subclasses of analytic functions by using the convolution operator. Several other operators with reference to these classes also under discussion. Our main focus is to generate some new results like inclusion results, integral preserving properties, arc length, rate of growth of coefficients, necessary condition for univalency, closure under convolution with convex functions and some radii results with the convolution operator. We also use some special functions to study properties of the convolution operator. Some application of this operator related to the conic domains is also discussed. The recently developed techniques that are convolution and differential subordination are used to explore some geometrical and analytical properties. The results obtained in this dissertation are also connected with the previously existing results in the literature of the subject.
