خواجہ عبدالمجید

خواجہ عبدالمجید
افسوس ہے پچھلے دنوں ملک کے مشہور نیشنلسٹ خواجہ عبدالمجید صاحب بیرسٹر ایٹ لا کا انتقال ہوگیا۔مرحوم صفِ اوّل کے نیشنلسٹ مسلمان اور قومی کارکن تھے۔ علی گڑھ کے تعلیم یافتہ اوراُس کی تہذیبی روایات کے پورے حامل ہی نہیں بلکہ ترجمان تھے۔برسوں سے مسلم یونیورسٹی کورٹ اوراُس کی اکزیکٹیو کونسل کے بہت بااثر ممبر تھے اوریونیورسٹی کے معاملات میں بڑے جوش وخروش اور سرگرمی سے حصّہ لیتے تھے۔بہت پرانے کانگریسی کارکن تھے اوراس لیے کانگریس کے عمائد اورپنڈت جواہرلال نہرو اورسابق صدر جمہوریہ دونوں خواجہ صاحب کابڑاادب اورلحاظ کرتے تھے مگر حق بات کہنے اورکرنے میں اُنہیں کبھی تامل نہیں ہوتاتھا۔بڑے مخلص،انتہائی وضعدار،شرافت ومروت اوراخلاق ومکارم کا نمونہ تھے، اُن کا دروازہ ہرضرورت مند کے لیے ہروقت کھلارہتا تھا۔ اب ادھربرسوں سے معذور تھے، مگرقومی کاموں میں اس کے باوجود تندہی سے منہمک رہتے تھے۔اب ایسے بزرگ کہاں ملیں گے۔اﷲ تعالیٰ انہیں مغفرت ورحمت کی نعمتوں سے سرفراز فرمائے۔ [جنوری۱۹۶۳ء]

 

شاہ ولی اللہ کی تعلیمات کی روشنی میں خانگی نظام: ایک تحقیقی جائزہ

Every Human being needs family system to live with dignity. There is joint family system, and separate family system in practice in Muslim Societies. Shah Waliullah gave concept of ideal family system. The ingredients of ideal family system of Shah Waliullah are Nikāḥ, Siblings, Property, Love and Society. People faced many problems for living respectfully, and born grave losses due to war. Shah Waliullah not only taught us religious teachings but also guided us how to make our socio- economic system strong as well as family system. In this article, his teachings and thoughts about family system have been discussed.

Modeling Effects of Different Irrigation and Fertigation Strategies on Maize Zea Mays Response and Salinity Buildup in Root Zone under Drip Irrigation

Crop and water productivity can be improved by growing crops under drip irrigation coupled with balanced fertigation and adequate irrigation scheduling. This study was conducted, during spring seasons of 2015 and 2016 at experimental area of Water Management Research Centre, University of Agriculture, Faisalabad, Pakistan to investigate the maize response and root zone soil behavior under different irrigation frequencies including daily irrigation, 3rd day irrigation and 5th day irrigation. Also three rates of recommended dose of fertigation (RDF) including L1: 100% of RDF, L2: 75% of RDF and L3: 50% of RDF were investigated using imported water soluble fertilizer (IM) as well as for indigenously developed water soluble fertilizer (WN) to check their effects on maize productivity and on its economic return. Crop response was studied in terms of plant height, dry matter weight, grain yields, harvest index and water productivity. Soil behavior was investigated in terms of soil moisture behavior and soil salinity buildup. The experiment was laid under Randomized Complete Block Design (RCBD) with 54 plots for eighteen experimental treatments with three replicates and three plots for control treatment. It was observed that daily irrigation frequency produced the highest values of crop growth parameters, which decreased when irrigation frequency moved from daily to 3rd day. Regarding crop growth parameters, the 5th day irrigation frequency showed better results than that under 3rd day frequency and worse results than that under daily frequency. The results also showed that the highest plant height (192.8 cm), dry matter weight (18.17 t/ha), grain yield (9.47 t/ha), water productivity (1.80 kg/m3) and net profit (Rs. 188323/ha) were produced using WNL1 (indigenous water soluble fertilizer at 100% RDF) with daily irrigation frequency compared with other treatments. Under daily irrigation, the significantly highest ECe (2.37 ds/m) was found in the top soil layers due to lesser downward movement of salts because of limited water applications. But due to frequent water applications under daily frequency than that under 3rd day and 5th day frequencies, enough soil moisture was present in top soil layers to support better crop growth. Drip irrigation saved 48% irrigation water with cumulative irrigation depth of 556 mm in comparison to conventional ridge sowing (1063 mm). Based on results, it is recommended that maize grown under drip irrigation should be fertilized by WNL1 with daily irrigation frequency for economically better return in semi-arid area of Faisalabad, Pakistan.
