Optimum nitrogen, its placement methods and seeding rates are important for enhancement of qualitative maize fodder production. This study therefore was conducted to determine how nitrogen, seed rates, N placement methods, N application timings, seed sowing patterns and their interactive effect can alter fodder yield. Field experiments thus were conducted at Students Farm, Department of Agronomy, Sindh Agriculture University, Tandojam, Pakistan, located at (25o25’60’N 68o31’ 60E) during 2007-2008 and 2008-2009. In all the experiments, maize variety Akbar was sown for fodder production. The study on effect of nitrogen levels and placements on maize fodder production consisted two seasons (spring and autumn), three N placement methods (broadcast, fertigation and side dressing) and five N levels (00, 60, 100, 140 and 180 kg ha-1). Application of 140 kg N ha-1 through fertigation resulted maximum leaves plant-1, stem girth, leaf area, leaf area index, leaf area duration, N concentration, N uptake, crude protein, crude fibre, crude ash and green fodder yield. Further increase in N levels exhibited non-significant increase in the values of plant traits except plant height; crop growth rate and total dry matter were maximum at 180 kg N ha-1. N broadcast or side dressing even at higher N rates (180 kg ha-1) did not show higher values of all plant traits as compared to N- fertigation. An antagonist interactive effect of N rates and placement methods was noted on net assimilation rate, being maximum in control plots and decreased as the N rates increased regardless of N placement methods. Maize phenology changed with increasing N fertilizer rates and placement methods. To reach V10 stage, application of 140 or 180 kg N ha-1 attained maximum days under N fertigation method. Maize also took more days to reach tasselling and harvesting stages respectively at higher N application at 180 kg N ha-1 through broadcast followed by application of 140 kg N ha-1 either by fertigation or broadcast, however, early tasselling and harvesting stages appeared in the control plots. The field investigations on effect of nitrogen scheduling and placement methods on maize fodder production, comprised growing seasons (spring and autumn), N placement methods (broadcast, fertigation and side dressing) and N scheduling (00, two spilt (at sowing and V4 stages), three spilt (at sowing, V4 and V6 stages), four spilt (at sowing, V4, V6, and V8 stages), five spilt (at sowing, V4, V6, V8, V10 and VT stages). Split application of 140 kg N ha-1 through fertigation at sowing,V4 and V6 stage recorded maximum leaves, plant height, stem girth, leaf area, leaf area index, leaf area duration, crop growth rate, total dry matter, N concentration, N uptake, crude protein, crude fibre, crude ash and green fodder yield compared to two, four or five N split applications. Further N split reduced the values of all traits. Opposite response of net assimilation rate was observed, being higher in the control plots and lower in the plots treated with nitrogen. Maize phenological traits had non-significant response from V4 to V6 growth stages. Three split N applications of 140 kg N ha-1 during sowing, V4 and V6 through fertigation significantly took more days to reach V8, V10 and tasselling stages respectively. However, at harvest maize fodder took more days in two N split applications through broadcast during sowing and V4 growth stage. Studies on effect of seed rates and row directions on maize fodder production involved seasons (spring and autumn), row directions (north to south, east to west, north-east to south-west, north-west to south-west, and cross sowing and seed rates (150, 175, 200, 225 and 250 kg ha-1). Maximum leaves, plant height, stem girth, leaf area, crop growth rate, total dry matter, N content, N uptake, crude protein and fodder yield were found when crop was sown through north-south row direction at 150- 175 kg ha-1 seed rate. Higher net assimilation rate was observed in cross sowing and seeding rate of 175 kg ha-1. Seed rates and row directions had non-significant effect on germination, crude fat, crude ash and all the phenological traits of maize. For enhancement of maize fodder production, present investigations conclude and recommend that maize could be sown at seed rate of 175 kg ha-1 by north- south rows orientation. Nitrogen would be split applied at 140 kg N ha-1 through fertigation method during sowing, V4 and V6 stages

جانے اپنے دل کو اس نے کتنا بدل لیا

جانے اپنے دل کو اس نے کتنا بدل لیا
ہم کو دیکھ کے اُس نے جو ہے رستہ بدل لیا

عشق کی پہلی ٹھوکر سے بھی کچھ نہ سیکھے ہم
الفت ہم نے وہ ہی رکھی چہرہ بدل لیا

کچھ بھی فرق رہا نہ اپنی اُس کی عادت میں
ہم نے خو د کو سارا اُس کے جتنا بدل لیا

کچھ دن کو تھی گئی اداسی پر واپس نہ لوٹے
اس کی خاطر گھر کا اپنے نقشہ بدل لیا

جس بستے میں یاد تھی رہتی اب ہے فکر ِ روزی
بوجھ توخود پہ لادے رکھا بستہ بدل لیا

حدیث کے انسائیکلوپیڈیا اور ان کا تعارف

Since the inception of the ancient era, it has been the utmost trial of scholars related to every field of knowledge that they could save the knowledge of various fields. For meeting the purpose of saving, different tasks had been done in different periods, but, the most appreciating one is the preparation of an encyclopedia. In every era, different encyclopedias of different arts have been designed. Although the processes in Islamic studies remained to continue and various encyclopedias in the Islamic studies were prepared in which the encyclopedia of hadith is the most popular. Therefore, the compilation of hadith has begun from the 3rd Islamic century and a large number of muhadiseen have rendered their best services in this field and represented Hadith and books related to all arts, but, along with that a very important task was to assemble all books of Hadith at one place so that no one may get in trouble to find the Hadith, but it was a hard nut to crack that is why Allah has chosen such scholars who have compiled all the Hadith with their untiring efforts out of them the topmost in the list are: Jama-al-Joma, Kanzal-al-Amal, Almusand-al-Jamia, Mosoaa, Jamiat-ul-ahadees-al-zaeefa wal-mozooat, and almudavina-tul-Jamia are included.

Feasibility Study of Introducing Pashto Language As a Medium of Instruction in Government Primary Schools of Khyber Pakhtunkhwa

A descriptive study was conducted to find out the feasibility of introducing Pashto language as a medium of instruction in government primary schools of Khyber Pakhunkhwa. Pashto is a provincial language of Pakistan. Due to its importance in our daily life and particularly in education, it was felt necessary to conduct a study on its feasibility. The main objectives of the study were: (1) To get information about available human resources for adopting Pashto as a medium of instruction with regard to trained teachers, translators for text books, curriculum developers, reviewers and authors; (2) To find out the tendency of teachers, parents and students towards Pashto medium of instruction regarding teachers, students and parents literacy skills (reading, writing and speaking ability) in Pashto; teachers knowledge of the contents of various primary school subjects in Pashto; teachers’ qualification in Pashto and teachers, students and parents’ preferences for Pashto medium of instruction; (3) To find out barriers in adopting Pashto as a medium of instruction; and (4) To explore the advantages and disadvantages of adopting Pashto as a medium of instruction. A representative sample of 1200 students, 600 teachers of government primary schools and 600 parents (of government school students) was selected through cluster sampling technique from six sampled districts i.e. Swat, Malakand, Nowshera, Peshawar, Kohat and Bannu. Two research instruments i.e. questionnaires and structured interviews were used for data collection. Questionnaires for teachers and parents (based on 2 & 3 points scale) while structured interview for students (based on 2 points scale) were used as the main research tools for data collection. The two data collecting instruments (questionnaires and interviews) were pilot tested on limited size of the sample (twenty teachers, forty students and twenty parents) and was improved prior to data collection. The researcher carried out extensive visits for data collection to the sample districts. The obtained data was tabulated, analyzed and interpreted using t - test and chi - square through SPSS version 19 software. No significance of difference was found between the mean scores of the sample with respect to the use of Pashto as medium of instruction. Majority of parents opposed Pashto medium of instruction, because they were thinking about the future of their children in respect of higher education and competitive examinations. Parents also pointed out that their children will be relegated to the provincial boundaries only. It was concluded that the use of Pashto language in teaching-learning process was helpful but was not considered feasible in the light of maximum respondents opined against its use as a medium of instruction.
