Impact of planting techniques, weed-crop competition periods, and weed control methods on yield potential of spring planted sugarcane variety HSF-240 was studied at Ayub Agricultural Research Institute, Faisalabad. The study was comprised of two experiments laid out in RCBD with a split-plot arrangement, quad replicated, with net plot size of 3.6m x 10m. In both experiments, two planting techniques viz. 60 cm apart rows in flat sowing technique and 120 cm apart rows in trench sowing technique were randomized in main plot. In first experiment seven weed-crop competition periods viz. throughout full season weed free, weed-crop competition for 45 days after sowing (DAS), 60 DAS, 75 DAS, 90 DAS, 105 DAS, and full season weed-crop competition were kept in sub plots. In second experiment, eight weed control methods viz. ametryn + trifloxysulfuron @ 750 g a.i. ha -1 , ametryn + trifloxysulfuron @ 750 g a.i. ha -1 + 4% urea, ametryn + trifloxysulfuron @ 562 g a.i. ha -1 + 4% urea, manual hoeing, ametryn + trifloxysulfuron @ 750 g a.i. ha -1 + mechanical weed control, ametryn + trifloxysulfuron @ 375 g a.i. ha -1 + sorghum & sunflower water extract each @ 15 L ha -1 and ametryn + trifloxysulfuron @ 187.5 g a.i. ha -1 + sorghum & sunflower water extract each @ 15 L ha -1 were randomized in subplots. Results revealed that on two years average, trench sowing by yielding 73.65 t ha -1 stripped cane yield, significantly superseded the flat sowing which gave 65.08 t ha -1 stripped cane yield. On the average of two years, zero competition (weed free throughout the season) recorded 92.21 t ha -1 stripped cane yield, significantly higher than any weed- crop competition period. However, weed-crop competition for 45, 60, 75, 90, and 105 DAS gave 104.26, 85.22, 75.40, 42.63, and 40.17 % stripped cane yield, respectively over weedy check. In second experiment, trench sowing gave significantly higher stripped cane yield of 76.20 t ha -1 than 71.40 t ha -1 in flat sowing technique. In weed control methods, ametryn + trifloxysulfuron @ 750 g a.i. ha -1 + mechanical weed control gave significantly higher stripped cane yield of 101.68 t ha -1 than all weed control methods as well as weedy check which gave 37.28 t ha -1 . Different weed control methods gave 18.03 to 179.29 % higher stripped cane yields over weedy check.

مولانا ابوسلمہ شفیع احمد

آہ! مولانا ابوسلمہؒ
(پروفیسر مسعود حسن)
۲۲؍ دسمبر کی دوپہر کو کلکتہ کے مسلمان ایک بڑے المناک سانحہ سے دوچار ہوئے، یہ سانحہ حضرت مولانا ابوسلمہ شفیع احمد صاحبؒ کی رحلت ہے، جو ۵-۴ ماہ کی طویل اور صبر آزما علالت کے بعد ۷۳ سال کی عمر میں اپنے مالک حقیقی سے جاملے۔ اناﷲ وانا الیہ راجعون، دوسرے دن صبح ۳۰:۱۲ بجے ان کے ہزاروں عقیدت مندوں اور جان نثاروں نے ان کے جسدخاکی کو پارک سرکس سے متصل ایک قبرستان میں جس کا نام ہم ’گورغریباں‘ ہے، یہ کہہ کر سپردخاک کیا کہ:
اے تیرہ خاک خاطرِ مہماں نگاہ دار
کیں نورچشم ماست کہ دربر گرفتہ ای
نور اﷲ مرقدہٗ و برد اﷲ مضجعہ
مولانا مرحوم کے نام اور مقام سے مجھے بہت پہلے سے واقفیت تھی، البتہ باقاعدہ نیاز اور تقریب ۱۹۵۹؁ء میں حاصل ہوا، جب مجھے مدرسۂ عالیہ کلکتہ کی پرنسپلی تفویض ہوئی اور میں مدرسہ پہنچا، مولانا مدرسہ کے ممتاز ترین اساتذہ میں تھے، تفسیر اور حدیث ان کے خاص موضوع تھے اور ان دونوں فنون کی بیشتر متداول کتابوں پر ان کی گہری نظر تھی، وہ مدرسہ کی اونچی جماعتوں میں درس دیتے تھے اور بڑی عزت و احترام کی نظر سے دیکھے جاتے تھے۔ میں مدرسہ میں کم و بیش ۵ سال رہا۔ اس پوری مدت میں میرے ان کے تعلقات مخلصانہ رہے اور جب میں وہاں سے رخصت ہوا تو اس کے بعد بھی ان کا اخلاص برابر جاری رہا۔ وہ اکثر میرے غریب خانہ پر تشریف لاتے، گھنٹوں بیٹھتے تھے۔ راقم الحروف بھی ان کی خدمت میں حاضر ہوتا تھا، ان ملاقاتوں میں اکثر علمی گفتگو ہوا کرتی تھی، کبھی کبھی حالات حاضرہ پر بھی تبصرہ ہوا کرتے تھے، مولانا ان مجلسوں میں علم و حکمت کے موتی بکھیر دیتے تھے۔
مولانا کو لکھنے پڑھنے اور تصنیف کا شوق...

دراسة قصيدة ياسالكا لمخدوم محمد هاشم التتوي رحمه الله: دراسة تحليلية وأدبية

The Poem “Ya Salikayah” is a collection of verses. Hazrat Makhdoom Muhammad Hashim Thattavi has compiled it and the main thing is that he has compiled these verses by in keeping with the literature and eloquence and rules. Such a compilation is not just a matter of every ordinary person rather, this work can be done by a person who is well aware of the rules of making of poetry and verses. Hazrat Makhdoom Muhammad Hashim Thattavi was well aware of these rules but he had mastered it. The thesis writer has described the expression style and thoughts of Hazrat Makhdoom Muhammad Hashim Thattavi in his thesis and also tried to prove that Hazrat Makhdoom Muhammad Hashim Thattavi had special kind of proficiency in Arabic despite he was Non-Arab which can be seen in his these verses. These verses show the special style of Hazrat Makhdoom Muhammad Hashim Thattavi which thesis writer has proven and also proved that he has compiled this collection of verses in the best style. According to the research of thesis writer this poem is not still in the form of a book but in the form of a pen and paper format. And thesis writer has also tried to prove that the thoughts which are in these verses belong to Hazrat Makhdoom Thattavi himself. He used to shape thoughts into ideas before compiling these verses and then used to put his sincere poetry in it and compile it. It is estimated from these verses that it is affected when the audience hears and reads these verses.

A Comparative Study of Ausubelian and Traditional Methods of Teaching Physics at Secondary School Level in Pakistan

The work reported here is an investigation about the effectiveness of two teaching methods (i.e. Ausubel teaching method and traditional teaching method) in the teaching of physics at secondary level in Pakistan. The main objectives of this study were to compare the relative effectiveness of these teaching methods on students’ achievement and attitude, and to find out the impact of pre-lab on the learning of the students. This experimental work was carried out for the period of thirty-five weeks in the physics classroom and laboratory of Govt. Comprehensive School, Jhelum (Pakistan). Sixty-two secondary school science students of class X were randomly selected for this experiment. The posttest-only equivalent group design was used for this study. It involved two groups; experimental and control. These groups were equated on the basis of marks achieved by the students in a test of 8 th class science. The different tools used to collect the data were; the Achievement tests, Post labs, and Attitude scale. Experimental group was taught through Ausubel’s teaching method while control group was taught through Traditional. To measure the achievement of the students in the science theory and practical, the researcher administered the following tools; Experimenter’s tools 1 & 2, and post-labs. The other achievement tests used in the study were the Term Tests 1 & 2 administered by the school, and the question paper of physics theory and practical constructed, administered and evaluated by the Board of Intermediate and Secondary Education Rawalpindi (SSC annual examination 2005). To measure the scientific attitude of the students, an instrument was constructed and validated and then administered to the whole sample. Data collected by tools were analyzed by the application of software, SPSS and presented in the form of mean scores. To compare the mean scores of experimental and control groups, t-test was employed. The study indicated that Ausubel’s teaching method was found more effective than traditional teaching method in improving the achievement of the students in the subject of physics as measured by experimenter’s tools, term tests and in the SSC examination, v2005. The study also showed that the use of pre-labs significantly improved the performance of the students. It has found in various significant indications that the new way of teaching has improved performance of the students in various tests and some evidence that attitude have changed. The nature of pre-lab and post-lab need more improvement and further investigation at other levels and regions. There relative effectiveness should be evaluated so that the more effective tool can be used in the future. The persistence increase in the standard deviations for the experimental group suggests that not all students benefited equally. This gives rise to another area ‘cognitive learning styles’ that should be explored. This study can be seen as an exploratory study and offers encouragements that the new approach has considerable value for the learners. It needs replication, using many teachers, with boys and girls, and in all disciplines of science.
