اکرامؔ سانبوی

اکرامؔ سانبوی (۱۹۴۲ئ۔۲۰۱۱ئ) کا اصل نام محمد اکرام ہے۔ آپ ریاست جموں کشمیر کے سرمائی صدر مقام جموں میں پیدا ہوئے۔ آبائو اجداد کا تعلق ضلع جموں کی تحصل سانبہ سے تھا۔ اسی لیے اکرام سانبوی کہلاتے تھے۔ قیام پاکستان کے بعد جموں سے ہجرت کر کے سیالکوٹ کے محلہ پورن نگر میں آباد ہوئے۔ آپ نے ایم ۔اے اردو اورنیٹل کالج لاہور سے کیا اور اس کے بعد جناح اسلامیہ کالج سیالکوٹ میں اردو کے لیکچرا ر کی حیثیت سے آپ کا تقرر ہوگیا۔(۹۵۱)
اکرام ؔغزل اور نظم کے شاعر ہیں۔ کالج کے زمانے میں انھوں نے کئی مزاحیہ مضامین اور افسانے لکھے جو کالج میگزین کے علاوہ کئی سطح کے ادبوں رسالوں میں شائع ہوئے۔ تنقیدی مضامین اور خصوصاً شاعری کا شوق بڑی عمر میں ہوا۔ اس لحاظ سے ان کی شاعری کی عمر کچھ زیادہ نہیں تاہم ان کے کلام سے ظاہر ہوتا ہے کہ ان میں ایک اچھا شاعر بننے کی پوری صلاحیت ہے۔ اکرامؔ کے کلام میں ہمیں گہرا سماجی شعور ملتاہے۔انھوں نے بڑی خوبصورتی سے اپنی شاعری میں اپنے ماحول کی شعری زبان میں عکاسی کی ہے ۔اور اس کے ساتھ ساتھ اپنے وقت کے مسائل کو بھی بڑی عمدگی سے پیش کیا ہے۔ ان کے ہاں ہمیں افسردگی اور بے چینی نظر آتی ہے۔ جو ان کے دل کی دنیا کی بھر پور عکاسی کرتی ہے۔ کچھ اشعار ملاحظہ ہوں:
ہر طرف یاس کا اندھیرا ہے

زندگی ہو گی اب بسر کیسے

بے ثمر ہو گئے شجر کیسے

بے صدا ہو گئے نگر کیسے
(۹۵۲)

زبان شعر میں قصہ اداس راتوں کا

لہو رُلائے گا اک بار غور سے تو سنو
(۹۵۳)

بہتر ہے مرا آج میرے ماضی کے کل سے

Impact Analysis of Higher Education Research Trajectory on Governance and Public Policy: A Case Study of Four Federal Universities of Pakistan

The research situates link between the graduate researches in four academic institutes of Islamabad and analyzes its impact on the public policy. The study explores the relevance of graduate research trajectory followed by various academic departments of four major federal universities in Pakistan in formulation and execution of public policy. The author collected last five years graduate level dissertation titles from four federal universities and classified them by using thematic approach. An interview guide/questionnaire is prepared accordingly. Chairpersons, deans, professors, bureaucrats, and parliamentarians were approached for semi-structured, in-depth interviews. This is a qualitative study using thematic and analytical approach. The research finds a lack of cohesion between the graduate research trajectory and policy needs of the public institutions. The absence of a national research vision and collaborative framework, difference in training cultures of bureaucracy and academia, lack of logistic support system, defective learning strategies, and an overall neglect for social sciences are the major reasons for incoherence. The analytical correlation of the recorded opinions reveals opportunities to maximize the relevance of the academic research in public policy domain

Effects of Mulching and Farm Manure on Water Use Efficiency, Soil Properties and Crop Growth While Using Brackish Water for Irrigation

In many arid and semi-arid regions, use of brackish ground water has become necessary for irrigation to balance rapidly increasing water demands. Addition of organic material such as farm manure and crop residues would be useful in improving soils that are otherwise deteriorated when brackish water is used for irrigation. Keeping in view role of mulching and farm manure in ameliorating ill effects of brackish water, two years (2009- 2011) field studies were conducted to evaluate the effects of mulching (control, 25, 50, 75 and 100 % soil cover) and farm manure (control, 10, 20 and 30 Mg ha-1) on water use efficiency, soil properties and crop growth. A randomized complete block design with four replications was followed for laying out the experiments. Four field studies were conducted at the research farms of the College of Agriculture D. G. Khan, Sub Campus of University of Agriculture, Faisalabad. In Study-1, two experiments were conducted following cotton- wheat rotation and in Study-2, two experiments were conducted following mung-wheat rotation. Crops were grown during their normal planting seasons, with recommended seed rate and planting methodology. These crops were irrigated with brackish water and measured amount of irrigation was ensured using cut-throat flume. Soil samples collected from 0-15, 15-30, 30-45, 45-60, 60-90 and 90-120 cm soil depth before sowing and at each crop harvest, were analyzed for EC1:5, pH, bulk density, N, P, K and organic carbon concentration. It was observed that the farm manure at 30 Mg ha-1 (FM4) and mulch at 7.6 Mg-1 ha (M5, 100 % SC) produced the maximum cotton, wheat and mung crop yield as compared to control. Whereas economic and marginal analysis indicates that FM4 gave more economical yield as compared to all other levels of farm manure and mulch during both of the years. As for as soil properties were concerned more soil bulk density was found in controlled treatments while less was found in M5 and FM4. Infiltration rate significantly decreased in M5 and FM4 applied plots compared to control. Maximum EC1:5 was obtained in control, where as minimum value was obtained in FM4 (30 Mg ha-1) and M5 (100 % Soil cover). Maximum values of NPK and soil organic carbon (SOC) contents were observed at maximum level of mulching (M5) and farm manure (FM4) as compared to control. The highest values of NPK, SOC, EC1:5, SAR, pH, soil bulk density and salt accumulation was observed at upper soil depth compared to lower soil depth whereas percent increase was more in lower soil depths as compared to upper soil depths. Maximum water use efficiency was obtained in case of FM4 and M5 as compared to control. Minimum salt concentration were observed in case of M5 (100 % soil coverage was done) and FM3 (20 Mg ha-1). Root length density of wheat crop was more in M5 and FM4 as compared to control and in upper soil layers as compared to lower soil layers. It is clear from the results that manuring and mulching improves the water use efficiency, physical and chemical properties of soil, enhance the yield of cotton, wheat and mung crops and also helpful in ameliorating ill effects of brackish water on soil and crop characteristics.
