Unwise use of herbicides has resulted in environmental and health problems not only for human beings and also for animals but it also caused some weed species to dominate fields due to resistance development against herbicides. Among the alternate ways of weed management in field crops application of allelopathy has shown tremendous scope in agricultural pest management. Different sowing methods and planting times has varying impact on the associated weeds. Studies on dynamics of weed flora and its management by allelopathy in wheat at varying sowing times planted by different methods were conducted at the Agronomic Research Area, Department of Agronomy, University of Agriculture, Faisalabad, Pakistan during 2008-09 and 2009-10. In the first experiment, weed flora under different sowing methods and planting dates was investigated. In second experiment allelopathic plant water extracts (PWE) of sorghum, sunflower and mulberry in combination with reduced doses of a herbicide in different sowing methods was evaluated. Whereas in third experiment, plant water extracts used in the second experiment in combination with reduced doses of a herbicide under different planting methods were assessed. Weed flora mainly consisted of Chenopodium album L. and Phalaris minor L., while few plants of Fumaria parviflora L., Avena fatua L., and Anagallis arvenses L. were also observed. It is noted that weeds if not controlled, can cause 60-66% yield losses in wheat. Maximum wheat productivity and net returns were obtained from wheat sown at November 15 on beds. Allelopathic PWE in combination with 1/3 rd dose of herbicide provided as effective weed control as was achieved from label dose of herbicide during 2008-09 and 2009-10 which caused substantial yield increase (54%), suggesting that herbicide dose could be reduced by 67%. For achieving eco-friendly weed control and maximum productivity allelopathic PWE combined with 1/3 rd dose of herbicide could be applied in wheat planted on beds at November 15.

 نسیم حجازی ۔۔۔۔تحریکِ پاکستان کا عملی کردار

عذرا پروین پی ایچ ڈی اسکالر

ناردرن یونیورسٹی، خیبرپختونخواہ

نسیم حجازی کا اصلی نام محمد شریف اور قلمی نام نسیم حجازی تھا ۔ نسیم حجازی ۱۹ مئی ۱۹۱۴ء کو پنجاب کے ایک گاؤں سوجان پور جو کہ قصبہ دھاڑیوال ضلع گورداس پور میں واقع ہے ، میں پیدا ہوئے۔ ۱۹۴۷ء میں تقسیمِ ہند کے بعد ہجرت کر کے پاکستان آ گئے اور مستقلاً یہیں رہائش اختیار کی ۔ زندگی کی ڈور ٹوٹنے تک آپ نے پاکستان سے اپنا ناتا نہیں توڑا۔بالآخر مارچ ۱۹۹۶ء کو اپنے خالقِ حقیقی سے جا ملے ۔ آپ کے آباؤاجداد حجاز سے ہندوستان میں وارد ہوئے اور اپنی رہائش کے لیے انھوں نے پنجاب کے ضلع گورداس پور کا انتخاب کیا ۔ نسیم حجازی کے والد کا نام چودھری جان محمد تھا جو کہ محکمہ انہار میں ملازم تھے ۔بچپن کے ابتدائی دور میں ہی آپ کی والدہ محترمہ داغِ مفارقت دے گئیں تو بارِ تربیت والد صاحب کے سر آن پڑا ۔ ابتدائی تعلیم سوجان پور ہی میں حاصل کرنے کے بعد ۱۹۳۸ء میں ماسٹرز کی ڈگری اسلامیہ کالج لاہور سے حاصل کی ۔ اسی دوران آپ نے چھوٹے موٹے موضوعات پر قلم آزمائی شروع کر دی ۔ افسانہ نگاری میں قدم رکھتے ہوئے نسیم حجازی نے اپنا پہلا افسانہ ‘‘شادر’’ تخلیق کیا ۔ اپنی ادبی زندگی کے ابتدائی دور میں وہ اپنے قلمی نام کی جگہ بھی اپنا اصلی نام ہی استعمال کرتے تھے لیکن بعد میں جب ان کے استادِ محرم نے انھیں مشورہ دیا کہ اپنے لیے الگ قلمی نام کا انتخاب کریں تو انھوں نے اپنے قلمی نام کے لیے حجازِ مقدس سےاپنی نسبت کوافضل جانا اوراپنے لیے نسیم حجازی کے قلمی نام کا انتخاب کیا...

Faktor-faktor yang mempengaruhi Integritas Laporan Keuangan (Studi Pada Perusahaan BUMN yang Terdaftar di BEI Periode 2020- 2022)

The aim of this research is to determine the influence of managerial ownership, audit committee, audit quality and company size on the integrity of financial reports. The objects in the research are state-owned companies registered on the IDX for the 2020-2022 period, totaling 20 companies. The sampling technique uses purposive sampling. Data analysis uses multiple linear regression. The research results explain that simultaneously managerial ownership, audit committee, audit quality and company size have a significant influence on the integrity of financial reports. While managerial ownership and company size have a negative and significant influence, the audit committee has a positive and significant influence, audit quality has a positive and insignificant influence.

Universalizing Nuclear Export Control Regimes: A Case Study of Non-Npt Nuclear Weapon States

Nuclear ECRs have a salutary impact on the mechanism for information sharing by the technology suppliers as well as countering proliferation risks. These informal arrangements have established some export-related rules to improve coordination and inculcated some habits among the states that might otherwise be involved in the proliferation of sensitive technologies. The Nuclear ECRs, despite being outside the framework of established non-proliferation treaties, have helped institute some recognizable non-proliferation norms and best practices. To the extent that the regimes are essentially supplier cartels, they have successfully managed the issue of selective denials and controlled the supply of nuclear proliferation-sensitive technology. Fundamentally, these regimes address NPT member states, yet three Non-NPT NWSs need to have access for peaceful purposes to nuclear technology. However, these states have been criticized for building nuclear weapons, keeping in view that they didn‘t violate any international law (as they have never been part of NPT). The study investigates the various possibilities of mainstreaming these three states, acknowledging their market potential in the realm of civilian peaceful nuclear technology and their plausible role in the non-proliferation struggle. The primary element of discussion and analysis in this study is that there is a need to mainstream the Non-NPT NWSs and to evolve the criteria for including the Non-NPT NWSs in the Nuclear ECRs. The central proposition of this research states that the world has transformed since 1968, so the international community needs to modify the mechanisms of the regimes in order to accommodate new markets and explore new venues of policy making in order to comprehensively address the nuclear proliferation concerns. There is a possibility to mainstream them because some are emerging markets and others have the potential to become future markets. Furthermore, they have acquired nuclear weapons so it is imperative to prevent them from horizontal proliferation by implementing stringent measures on the export controls. The study investigates the policy recommendations for the global community to address the NonNPT-NWSs in the Nuclear ECRs. This research is cognizant of the dire need to mainstream the Non-NPT NWSs in the Nuclear ECRs. India, although is a non-member of the NPT, has been given the NSG waiver along with AG, MTCR and WA membership. This action has raised questions on the credibility of the Nuclear ECRs as this discriminatory step weakens the mechanism of these regimes. An analysis of the underlying dynamics of this exceptional treatment of India has evolved the debate of developing an approach based on criteria to address the Non-NPT NWSs in the Nuclear ECRs. This study encompasses an analysis of the emerging trends and the imperatives for setting up uniform criteria for all three Non-NPT NWSs and taking into loop all the states having nuclear weapon technology. This proposed solution will help counter the proliferation issues, especially that of horizontal proliferation. The research hypothesis was evidenced to be true in finding the correlation between the requirement of mainstreaming these states in the Nuclear ECRs and the debate on criteria-based approach.
