Onion is the major vegetable crop not only in Pakistan but also in other countries of the world. The onion bulb yield lies in the lower level than to other more developed areas of the world. Many reasons rose for this less yield. But the most important among all of them is the attack of pest insects and among insects the onion thrips is the notorious one .In the present study the efficacy of the insecticides i-e Dimethoate, Confidor, Lasenta, Proaxis and Spinosad was determined against thrips to in farmer?s field for two adjacent years. The data was collected before and then after the 24h, 72h, and 7 days of the use of insecticides. The analysis of this data revealed that all of the insecticides reduced thrips population. However, maximum reductions (3-1%) per plant in thrips population and increase in onion bulb yield (33.06t/ha) was attained with Dimethoate 40 EC. Whereas lowest onion thrips population and onion bulb yield (23.7 t/ha) was obtained from control plot where no insecticide was used against thrips. Therefore, the insecticide Dimethoate 40EC can be recommended for the control of onion thrips on onion crop.

پروفیسر خواجہ احمد فاروقی

پروفیسر خواجہ احمد فاروقی
جنوری کا معارف مرتب ہوچکا تھا کہ یہ اندوہ ناک خبر ملی کہ اردو کے مشہور محقق و نقاد صف اول کے ادیب اور صاحب طرز انشاء پرداز پروفیسر خواجہ احمد فاروقی ۳۱؍ دسمبر کو رحلت فرماگئے۔ اِنا ﷲ وَاِنا اِلیہ رَاجِعونْ۔
خواجہ صاحب کا خاندان علم و فضل اور سلوک و تصوف میں ممتاز تھا، انھیں انگریزی تعلیم دلائی گئی مگر اس کے باوجود بھی وہ شرافت، وضع داری اور اپنی دیرینہ خاندانی روایات کے حامل تھے۔
۱۹۱۷؁ء میں وہ بچھراؤں ضلع مراد آباد میں پیدا ہوئے، ۱۹۲۷؁ء میں گورنمنٹ ہائی اسکول ہردوئی کی پانچویں جماعت میں داخلہ لیا، یہاں ان کے والد سررشتہ دار تھے، ۱۹۳۲؁ء میں اعلیٰ تعلیم کے لیے میرٹھ کالج میں داخل ہوئے، تعلیم مکمل کرنے کے بعد معلمی کے پیشہ سے وابستہ ہوئے جس کا آغاز مسلم یونیورسٹی اسکول میں کیمسٹری کے استاد کی حیثیت سے کیا، پھر بعض کالجوں سے وابستہ رہنے کے بعد ۱۹۴۶؁ء میں دہلی کے اینگلو عربک کالج میں اردو کے لکچرر ہوئے، جس کے بعد دہلی ہی میں بودوباش اختیار کرلی، خود رقمطراز ہیں:
’’اس وقت سے کہ چالیس سال ہوگئے ہیں، دلی کاروڑا ہوں اور یہ دلی کی گلیاں کسی طرح نہیں چھٹتیں‘‘۔
حزیں از پائے رہ پیما بسے سرگشتگی دیدم
سرشوریدہ بربالین آسایش رسید ایں جا
۱۹۴۸؁ء میں دلی میں چاروں طرف آتش زنی، غارتگری اور قتل عام مچا ہوا تھا اور موج خوں سروں سے گزر رہی تھی، مگر خواجہ صاحب اس قلزم خون کے شناور بنے رہے۔
وہ بچپن ہی میں مطالعہ اور کتب بینی کے عادی ہوگئے تھے اور تقریر و تحریر کی مشق بھی شروع کردی تھی، ہردوئی ہائی اسکول میں جب زیر تعلیم تھے تو غنچہ (بجنور) اور پھول (لاہور) کے لیے مضامین لکھتے رہتے تھے۔ اسی زمانے میں اپنے ایک ہم جماعت کے اشتراک...

حكم شراء البيوت للسكنى عن طريق القرض من البنك الربويل لأقليات المسلمة

This paper highlights and provides the reader with comprehensive view of the treatment of loans from the Riba-based banks in the West. It deals with the "rule of buying houses for housing through the loan from the Riba-based bank for Muslim minorities" and some of the issues that are presented to the Muslim, Issues associated to this subject. This discussion is followed through a number of suggestions to redress these problems

Genetics of Morpho-Physiological Traits in Wheat under Normal and Drought Conditions

Six bread wheat cultivars/lines viz., Faisalabad-08, Lasani-08, Sehar-06, Chakwal-86, Chakwal-50 and 6302 were hybridized in full diallel fashion. Thirty F1 crosses along with six parents were planted in a triplicate randomized complete block design in the experimental area of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad. Experiment was sown under both normal and drought conditions. Data on attributes viz., plant height, flag leaf area, number of tillers per plant, number of spikelets per spike, number of grains per spike, 1000-grain weight, spike length, spike density, grain weight per spike, biomass per plant, grain yield per plant, harvest index, extrusion length, stomatal frequency, stomata size, epidermal cell size and leaf venations were recorded and subjected to the analysis of variance technique to find out the genotypic differences for the characters, which were found significant under both environmental conditions. Data were further subjected to diallel analysis for genetic studies. The Vr-Wr graphs indicated over-dominance type of gene action for spike length and grain weight per spike and leaf venations under both sowing conditions and for flag leaf area, biomass per plant, harvest index and stomatal frequency under normal condition, whereas for number of tillers per plant under drought condition. Additive with partial dominance type of gene action was observed for number of spikelets per spike, number of grains per spike, plant height, 1000-gran weight, grain yield per plant, extrusion length, spike density, stomata size and epidermal cell size under both sowing conditions and for number of tillers per plant under normal condition and for biomass per plant, harvest index, stomatal frequency and flag leaf area under drought condition. Over-dominance type of gene action detected under normal condition for flag leaf area, biomass per plant, harvest index, and stomatal frequency was changed to additive with partial dominance type of gene action under drought condition, while additive with partial dominance gene action under normal condition for number of tillers per plant was altered to over-dominance type of gene action under drought condition
