Laboratory and field experiments were conducted on seed soaking (0, 3, 6, 9, 12, 15, 18, 21 or 24 h), seed priming (100, 200, 300 or 400 ml nutrient solution and Riverum), Poly Ethylene Glycol (PEG) 10000 (4, 8, 12 or 16 g) L -1 of deionized water) and hydro-priming along with fungicide (Ridomil MZ 72 WP) on pearl millet cultivars viz. 18-BY, MS-2, DBR-3 and MH-7077 at Agronomy Department, NWFP Agricultural University Peshawar, and Cereal Crops Research Institute, Pirsabak, Nowshera, Pakistan, during 2004, 2005 and 2006. The objectives of the study included water absorption estimation by the seed in unit time, seed soaking and osmotica concentrations response to germination parameters, fungicide efficacy for downy mildew (DM) control and performance of primed seed in the field on yield and yield components. Seed moisture absorption increased enormously during the first 3 h of soaking and declined thereafter. Seed soaking for 6 h enhanced germination, radicle and plumule growth while, lowest germination and shortest radicle and plumule were observed for 24 h soaking. PEG 10000 @ 12 g, Riverum or nutrient solution @ 300 ml L -1 of deionized water gave the highest germination, radicle and plumule growth. In field experiment seed priming enhanced germination, emergence, flowering, leaf area, leaf area index, tiller number plant -1 , plant height, maturity and head length. Heavier grains and more grain, stover and biological yields were recorded for primed seed than non-primed. The cultivars tested showed differential response to various attributes. MH-7077 was the earliest in flowering and maturity. Cultivar 18-BY recorded the highest leaf area, leaf area index and head length. The highest grain number head -1 , grain weight, grain yield and harvest index was observed in MH-7077. The cultivar MS-2 excelled in tiller number plant -1 , plant height, stover and biological yield. Seed priming with PEG 10000 @ 12 g, nutrient solution or riverum @ 300 ml L -1 diionzed water in MH-7077 may be used for higher grain production. Ridomil was effective in controlling DM disease. The DM disease score was lower in hydro- primed seed than non-primed but higher than osmo-primed seed plots.

چودھری خلیق الزماں

چودھری خلیق الزماں
افسوس ہے کہ گزشتہ مہینہ چودھری خلیق الزماں مرحوم کا کراچی میں انتقال ہوگیا، مرحوم ان لوگوں میں تھے جن کی پوری زندگی سیاسی اور قومی کاموں میں گزری، سیاست کا چسکا ان کو طالب علمی ہی کے زمانہ سے تھا، چنانچہ جنگ بلقان کے زمانہ میں ہندوستان سے جو طبی وفد ڈاکٹر انصاری مرحوم کی قیادت میں ٹرکی گیا اس میں جو نوجوان شامل ہوئے تھے ان میں ایک چودھری صاحب بھی تھے، کئی مرتبہ لکھنو میونسپلٹی کے چیرمین ہوئے ان کی چیرمینی کا دور ایک یادگار دور تھا، اسی زمانہ میں خلافت اور ترک موالات کی تحریک شروع ہوئی، اس میں اس سرگرمی سے حصہ لیا کہ صوبے کے لیڈروں میں ان کا شمار ہونے لگا، ایک مدت تک کانگریس میں رہے، پنڈت موتی لال کے معتمد علیہ اور جواہر لال کے خاص رفقاء میں تھے، کانگریس میں بھی نمایاں مقام حاصل کیا، چنانچہ ۱۹۲۹؁ء میں جب کانگریس کے لیڈروں کی گرفتاری کا سلسلہ شروع ہوا تو آخر میں ان کو کانگریس کا ڈکٹیٹر مقرر کیا گیا تھا۔
پھر مسلم لیگ میں شامل ہوگئے اور پاکستان کی تحریک میں چند دنوں میں آل انڈیا لیڈر کی حیثیت حاصل کرلی چنانچہ پاکستان کے بانیوں میں ان کا شمار ہوتا ہے، قیام پاکستان کے بعد کراچی چلے گئے، یہاں بھی ان کو بڑے بڑے عہدے حاصل ہوئے مختلف اوقات میں مسلم لیگ کے صدر مشرقی پاکستان کے گورنر اور انڈونیشیا کے سفیر مقرر ہوئے مگر مسٹر جناح ان سے خوش نہ تھے اس لئے وہ پاکستان کی سیاست پر اثر انداز نہ ہوسکے اور آخر میں گوشہ نشینی کی زندگی اختیار کرلی تھی اور اسی پر ان کا خاتمہ ہوا، چودھری صاحب کی زندگی قلندرانہ تھی، وہ وکیل تھے، ان کے ماموں اور خسر مولوی محمد نسیم صاحب لکھنو کے چوٹی کے وکیل اور...

Pesantren Virtual: Dinamisasi atau Disrupsi Pesantren?

The industrial revolution that penetrated the world of education forced Islamic boarding schools (Pesantren), as part of education, to mutate in new form to find the ideal format as an adaptive step to keep up to date. Pesantren which have a cultural base of traditional society make various efforts to make acculturation with technology. The efforts of these pesantren can be seen from the number of pesantren websites, which provide information about pesantren and religious programs online. On the other hand, virtual pesantren have also emerged, which do not have a real pesantren institutional base in the community, using online media as an operational base. Some of these virtual Islamic boarding schools have strong buildings in cyberspace, with a wider reach than Islamic boarding schools. Its flexible and open nature makes virtual pesantren have their own community in cyberspace. Furthermore, problems arise when virtual Islamic boarding schools intersect with conventional Pesantren in cyberspace. This research is a library research that uses printed and online media as data sources. This study aims to find differences in the characteristics of virtual pesantren, and their relationship with the dynamics of pesantren in the era 4.0. From the content analysis conducted at several virtual pesantren, it was found that some of them used the same name as real pesantren, thus creating ambiguity of virtual pesantren

Influence of Fruit Thinning Intensity, Calcium and Gibbrellic Acid Application on Fruit Yield and Quality of Peach

A research study entitled “Influence of thinning intensity, calcium and gibbrellic acid application on fruit yield and quality of peach” was conducted at Horticulture Research Farm and Post harvest Laboratory, The University of Agriculture Peshawar (UAP) in the year 2014-15. The present research project consists of four interlinked experiments. The 1st experiment entitled “Effect of thinning intensity and time on quality fruit yield of peach”. Various thinning intensity i.e. 0, 20, 40 and 60% and thinning time i.e. 7, 14 and 21 days after fruit set) were carried out in peach fruit trees. The experimental results showed that peach fruits trees thinned 60% after 7 days of fruit set significantly improved all the studied attributes but showed more split pits incidence and inferior quality yield of peach. However, the results of 60% fruit thinning were statistically at par with peach fruits thinned 40% after 14 days of fruit set with less split pits incidence and good quality fruits, hence recommended for better quality fruit production of peach. In order to overcome the problem of split pits, another field experiment entitled “influence of irrigation intervals and gibbrellic acid concentrations (GA3) on the split pit incidence and fruit quality of peach” was conducted during the year 2015. Keeping irrigation intervals in main plots and various concentrations of GA3 in subplots, peach trees were irrigated with different intervals (5, 10 and 15 days), sprayed with gibbrellic acid (GA3) concentrations (0, 50, 100 and 150 ppm) in already thinned plant (40% fruit thinning after 14 days of fruit set) optimized from the previous year experiments. The experimental results showed that peach fruit trees irrigated after every 10 days significantly increased the leaf area and other fruit and quality related attributes but most importantly reduced the incidence of split pits. Moreover, application of 100 GA3 concentration proved to be the best in controlling split pit incidence of peach with improving the yield and quality related attributes of peach. Hence, peach fruit trees could be irrigated after every 10 days along with 100 ppm GA3 concentration for better quality fruit production of peach with minimum incidence of split pits. As peach is a highly perishable commodity with short post harvest life. Hence, the third pre and post harvest experiment was conducted to retain the quality attributes of peach with longer shelf life. Various calcium sources (Calcium chloride, calcium nitrate and calcium sulphate) were sprayed at different concentration (0, 0.50, 0.75 and 1.0%) on peach fruit trees and the 2 harvested fruits were kept in storage for 30 days with 10 days interval having storage temperature of 8±2 0C at 50% Relative Humidity. The experimental results showed that some of the quality attributes like fruit firmness, fruit calcium content, TSS, TSS-acid ratio of peach fruits were better retained for 30 days by the pre harvest foliar application of 1.0% CaCl2 with minimum percent brown rot incidence, weight loss, ion leakage from cell membrane and cell wall. However, the effect of calcium sources and concentration on other quality attributes such as ascorbic acid content, percent acidity, reducing sugars and non reducing sugars of peach fruits were found non-significant. Pre harvest application of calcium chloride at 1% significantly retained the pre harvest and some of the post harvest attributes but could not retained the other studied quality attributes of peach, so to further enhance the quality of peach fruits, another post harvest experiment entitled “effect of 1-Methylcyclopropene (1-MCP) concentrations on storability of Peach fruit cv. Early Grand” was conducted during year 2015. Optimum source and dose of calcium (optimized from the previous experiment i.e. calcium chloride at 1%) was applied pre harvest to peach fruit trees. The treated fruits were then dipped in different levels of 1-MCP (0, 0.3, 0.6 and 0.9 μg L-1), stored for 40 days at temperature of 8±2 0C with 50% RH. The experimental results showed that 1-MCP at 0.9 μg L-1 reduced weight loss, fruit decay, total soluble content, TSS-acid ratio while retained fruit firmness, acidity, ascorbic acid, reducing sugars, free radical scavenging assay, catalase activity, total phenols and antioxidant activity of peach fruits. Peach fruits stored for 40 days showed better performance for most of the quality attribute up to consumer preferences. However, free radical scavenging assay, catalase activity, total phenols and antioxidant activity increased up to 30 days but declined up to 40 days of storage. Therefore, an integrated management of peach fruits with 40% thinning after 14 days of fruit set, irrigated after 10 days, sprayed with 100 ppm GA3 concentration enhanced the fruit size, weight, yield and quality of peach fruits with lower split pit incidence. Moreover, peach fruits trees could be sprayed with CaCl2 at 1.0% and later on treated with 0.9 μg L-1 1-MCP solution for retaining the quality attributes of peach fruit up to 40 days of storage (Temperature = 8±2 0C and 50% RH).
