رسائل و جرائد

شعر و ادب کو پروان چڑھانے میں ادبی شخصیتوں کا اپنا مقام و مرتبہ ہے یہ کیسے ہو سکتا تھا کہ رسائل و جرائد اور اخبارات ان سے پیچھے رہتے خطہ سیالکوٹ کے مقامی رسائل و جرائد اور اخبارات ادب کی ترقی کے لیے ماضی سے اہم خدمات سر انجام دیتے چلے آرہے ہیں۔ان میں ’’نوائے سماج‘‘،’’ندائے سیالکوٹ‘‘،’’ہمدرد پاکستان‘‘ ،’’محنت کش‘‘ اور ’’شبنم‘‘ اہم رسائل و جرائد میں شمار ہوتے ہیں۔ان رسائل و جرائد اور اخبارات کے باقاعدہ ادبی ایڈیشن بھی شائع ہوتے رہے ہیں۔

          سیالکوٹ کے اخبارات کی موجودہ صف میں ’’صدائے شہر‘‘ ،’’نوائے شمال‘‘ اور ’’اخبار سیالکوٹ‘‘ نمایاں اخبارات ہیں۔رسائل و جرائد کی فہرست میں ’’مرے کالج میگزین ‘‘،’’مفکر‘‘،’’کاوش‘‘، ’’افق‘‘،’’محورِحیات ‘‘، ’’اقدار‘‘، ’’ادراک‘‘، ’’انتخاب‘‘، ’’کیہان‘‘، ’’یدبیضا‘‘، ’’گجر‘‘، ’’کرائیڈن‘‘، اور’’سٹی میگ‘‘آج بھی ادبی خدمات میں اہم کردار ادا کر رہے ہیں۔

          ’’گجر‘‘ ،’’انتخاب‘‘،’’ید بیضا‘‘ تاب اسلم کے شعور و فکر کا نچوڑ ہیں ان تینوں رسائل وجرائد کو تاب اسلم بڑی عرق ریزی سے ادبی دنیا کے سامنے پیش کرتے رہے ہیں۔ان ادبی رسائل نے بہت سے نئے لکھنے والوں کی راہنمائی کا فریضہ سر انجام دیا ہے۔تاب اسلم کے ان جرائد کو نہ صرف سیالکوٹ بلکہ برصغیر پاک و ہند کے نامور ادبا و شعرا ،ناقدین اور محققین کا قلمی تعاون حاصل رہا۔سیالکوٹ کے اہم ادبی رسائل و جرائد کے تعارف کے لیے تفصیل پیش کی جاتی ہے۔

نصاب سازی میں تربیتی واخلاقی جہات: عصری ترجیحات اور فقہ السیرۃ

For the development of Muslim society it is necessary that its people should be trained on the basis of Islamic teachings. This could not be possible until we design a curriculum of seerah which is according to the contemporary needs of character building. The purpose of designing such curriculum is to train our youth in such a way that they would be able not only to take advantage from our rich tradition but also they are well prepared to hold the leadership of the country. We have to keep in mind, while designing seerah curriculum, that it is not revealed. Infact we have to design it according to the needs of hour. If we keep in consideration the ideological and contemporary requisites than we would be able to get the desired results. Islam provides basic principals in this regard. Following these instructions we would be able to design a curriculum which produced the required results.

Interference and Weed Control Studies in Direct Seeded Fine Rice

Laboratory and field experiments were conducted to study interference and weed control in direct-seeded rice. The effect of root, shoot, leaf, seed and whole plant water extracts of Trianthema portulacastrum, Dactyloctenium aegyptium and Eleusine indica on germination and seedling growth of rice was studied in Petri dish bioassays. The seed germination was recorded daily for sixteen days. Rice seeds were also sown in sand culture to assess the seedling growth of rice with same water extracts. The maximum reduction in rice germination was observed with leaf extract of T. portulacastrum. Significantly lower root and shoot length of rice seedlings was observed where rice seeds were treated with water extracts of leaf and whole plant of T. portulacastrum. Germination and early growth of rice was affected the most by application of leaf extract of T. portulacastrum to rice before sowing compared with extracts of other weeds. A laboratory experiment was also conducted to evaluate the allelopathic effects of water extracts of sunflower and sorghum alone and in combination on the germination and early growth of rice and weeds viz: Trianthema portulacastrum, Dactyloctenium aegyptium and Eleusine indica. Sunflower and sorghum water extracts when applied in combination caused the maximum inhibitory effects on germination of E. indica and T. portulacastrum than when applied separately. Sorghum water extract caused maximum reduction in germination percentage of seeds of T. portulacastrum. Whereas, sunflower water extract caused maximum inhibitory effects on mean germination time of D. aegyptium seeds. Water extracts of sorghum, sunflower when applied alone and in combination increased the root, shoot length and the seedling biomass of rice over control. Combined application of sorghum and sunflower water extracts resulted in greatest root length reduction in T. portulacastrum. It was concluded that the combined application of sorghum and sunflower water extracts is overall more inhibitory to the germination of rice, T. portulacastrum, D. aegyptium and E. indica than when applied separately. However, the sorghum and sunflower mixture promoted the seedling growth of rice. Two field experiments were conducted to determine the most suitable sowing time, the critical period of weed-crop competition, and most effective methods of controlling weeds in direct-seeded rice. These experiments were laid out in a randomized complete block
