Rice (Oryza sativa L.) is one of the most paramount staple foods of the world. It occupies a unique position in cereal crops with respect to area under cultivation and more than 2.7 million populations depending on rice. In Pakistan, rice is an important food and cash crop and has the status of second staple food crop after wheat and the second major exportable produce after cotton. Despite much development in rice production technology research and developments, the yield of rice crop in Pakistan is very low as compared to other rice growing countries. One of the major yield limiting factors is the attack of insect pests and diseases. Among these, leaf folder (LF) Cnaphalocrocis medinalis (Gu.) and bacterial leaf blight (BLB) of rice are of economic importance and cause irreparable yield losses every year. A comprehensive survey was conducted to investigate the farmers’ perception regarding leaf folder and bacterial leaf blight and factors which boost up the infestation of leaf folder and incidence of bacterial leaf blight and their management practices in rice crop. A questionnaire was developed; minimum of 50 farmers were interviewed in selected five districts of Punjab, Pakistan. Majority of the farmers (62%) responded that LF attacked their crop first while 30% farmers were of the opinion that BLB attacked first. Eight percent informed that crop was attacked by LF and BLB simultaneously. As most of the farmers (72%) responded that those fields in which LF attacked first, the incidence of BLB was high, while 64% farmers told that LF enhanced the severity of BLB. Furthermore, the interaction among leaf folder and bacterial leaf blight was also studied. Total damage area (TDA) in the combined treatment (LF+Xoo) was significantly higher (72.08±1.57) than in the combined treatment (Xoo+LF), single LF treatment and single Xoo treatment on rice variety Basmati 385 and same trend was followed by 2nd week and 1st week. This implies a synergistic interaction of LF and xiv Xoo when Xoo was inoculated after LF infestation. However combined treatment of (Xoo+LF) showed a significantly lower TDA (59.28±1.47) compared with other combined treatment (72±1.57) and single LF and Xoo treatments. The data regarding yield contributed factor and yield losses due to leaf folder and bacterial leaf blight alone and combined were also recorded. The data revealed that maximum 1,000 grain weight loss due to BLB was 13.22% and 6.79% for years 2012 and 2013 respectively, on Super Basmati followed by Basmati 515 and Basmati 385. The highest 1,000 grain weight loss due to LF was 7.09% and 1.20% on Super Basmati followed by Basmati 515 and Basmati 385. The maximum 1,000 grain weight loss due to combined treatment (LF and BLB) was 20.06% and 7.07% on Super Basmati followed by Basmati 515 and Basmati 385 during 2012 and 2013 respectively. The maximum yield loss due to BLB was 20.62% and 10.55% on Super Basmati followed by Basmati 515 and Basmati 385. The yield loss due to LF was 10.32% and 3.48% on Super Basmati followed by Basmati 515 and Basmati 385.The yield loss due to combined (LF and BLB) was 27.05% and 11.02% on Super Basmati followed by Basmati 515 and Basmati 385. The leaf damage data revealed that two wild species, Oryza rufipogon and Oryza brachyantha were resistant to LF. Fourteen genotypes were moderately resistant (MR), ten were moderately susceptible (MS), fourteen were susceptible (S) and ten were highly susceptible (HS) against leaf folder. Similarly results exhibited that one wild species (O. rufipogon) was found highly resistant (HR) whereas one species (O. brachyantha) showed resistance (R) response. Two rice genotypes showed moderately resistant (MR) response; nine rice lines represented the moderately susceptible (MS) response, thirty three were represented susceptible response (S) and four were found highly susceptible (HS) against bacterial leaf blight. These identified resistant germplasm can be used in breeding program of rice crop to develop resistant varieties against leaf folder and bacterial leaf blight disease.
بہت کم لوگ ایسے ہوا کرتے ہیں جنہیں قدرت شعری صلاحیت سے نوازتی ہے۔ اقبال پر شعری کیفیت طاری ہوتی تو وہ دیر تک جاری رہتی تھی۔ اقبال نے پندرہ سال کی عمر میں شعر کہنا شروع کیا۔ آپ نے اپنا فکری پیغام شاعری کے وسیلے سے عام کیا۔ خطوط، خطبات، مضامین اور مقالے وغیرہ اقبال کے فکری اسالیب کے نمونے ہیں۔ خطوط کی تعداد تو بہت ہی زیادہ ہے۔ انہیں کلیات کی صورت کجا بھی کیا گیا ہے۔ شعری کلام کی ترتیب کے وقت اقبال نے کلام کا بہت سا معقول حصہ حذف کر دیا جسے باقیات کے نام سے جمع کیا گیا۔ اقبال کی بعض انگریزی تصانیف کے اردو تراجم ہوئے۔ بہت سی تصانیف کے نئے ایڈیشن سامنے آئے۔ پروفیسر عبد الحق نے سابقہ مونوگراف کی طرح اس میں بھی تصانیف کا مختصر تعارف پیش کیا ہے۔
Allah Almighty has completed this world by the creation of human being. He Almighty has made the men superior than the other creation of all the world .By his creation Allah Almighty has designated some responsibilities to him as well. If He will fulfil these responsibilities and do right deed, Allah almighty will pleased by him and he will deserve the Heaven and if he will not fulfil his responsibilities which were designated by Allah almighty and will misconduct, then due to misconducting of his deeds he will go to Hell. By this article, I tried to describe the meaning of man and point out the process and stages of creation of human, his responsibilities and some hidden but bitter facts about human life. When a person accept and understand these facts, his life will be easy. In this research paper descriptive method of research has been adopted by researcher
This study investigates the role of financial and operating leverages in firms? profitability before and after financial recession/crisis of 2008 focusing on chemical sector firms listed on the Pakistan Stock Exchange (PSX). The period of study selected is from 2004 to 2015. The ROE is taken as dependent variable. The Financial Leverage (FL) and Operating Leverage (OL) are chosen as independent variables or predictors. Three other variables like Assets Utilization (AU), Non-Debt Tax Shield (NDTS) and Age have been introduced as control variables. Another variable named Pre/Post is introduced as a dummy variable for the indication of pre and post financial crisis 2008.
A population of all 43 firms listed on PSX is selected. The 29 chosen firms relate to the chemical sector directly whereas 14 firms are indirectly related to the chemical industry.The data used in the analysis has been gathered from secondary sources i.e. from the SBP?s publications. The regression model used is panel linear model (PLM). The unbalanced data panel has been used in the analysis. Similarly, the random effect approach has been applied.The Stata statistical software has been used to estimate the relationship between predicted/dependent and predictor/independent variables.
Following outcomes have been accomplished after the examination; the FL has a negative but significant relationship with the firm?s profitability whereas the OL has a positive but non-significant relationship with the firm?s profitability. The AU has shown a positive and significant relationship with the firm?s profitability. Whereas other predictors like Age, NTDS have proved a positive but non-significant relationship with the firm?s ?ROE?. Both types of leverages have shown a negative impact on the firm?s profitability after the global financial crisis in 2008.
Keywords: Profitability, Financial leverage, Operating leverage, Assets Utilization, Age, non-debt tax shield, Financial Recession/Crisis 2008 and Pre/Post.
