Widespread herbicide resistance in Phalaris minor Retz., is a major bottleneck towards sustainability of wheat-based cropping system in Pakistan and many other Asian countries. A dose–response assay was conducted for confirmation of resistance in surveyed populations. Optimization of herbicide mixtures to control P. minor in wheat was done under wirehouse conditions. To manage P. minor efficacy of herbicide mixtures in integartion with crop row spacings and allelopathic crop mulches were investigated at the Agronomic Research Area, Department of Agronomy, University of Agriculture, Faisalabad over two consecutive growing seasons during winter 2014-15 and 2015-16. Most of the collected populations were resistant to fenoxaprop-P-ethyl. Resistance levels were 2.13-6.50. The tested herbicide mixtures both at 75 and 100% of the recommended dose of each mixture component provided effective control of resistant P. minor without any phytotocity on wheat. The herbicide mixtures provided consistent, effective control of P. minor under field conditions especially in 11.25 cm rows compared to in 22.50 cm wheat row spacing. Integrated use of allelopathic crop mulches and herbicide mixtures was effective to control of P. minor in wheat. They consistently enhanced the wheat yield by 23-39% and 24-35% during 2014-15 and 2015-16, respectively. The confirmation of ACCase inhibitor resistance as the first case of herbicide resistance in Pakistan leads us to discourage use of ACCase inhibitor herbicides alone. However, herbicide mixtures both at 75 and 100% of the recommended dose are suggested to manage this weed for sustainable wheat production in the surveyed cropping systems. Integration of herbicide mixtures with narrow row spacing of wheat and allelopathic mulches can help address herbicide-resistant P. minor in wheat fields.

اچھائی؍نیکی دا بدلہ

کسے ملک اتے اک ظالم بادشاہ حکمرانی کر رہیا سی۔ اوہ اپنی رعایا اتے بہت ظلم کردا تے اوس دے دربار وچوں کسے نوں وی انصاف نئیں سی ملدا۔ جو وی اوس دے خلاف بولدا، اوہ اوس نوں جانوں مار دیندا سی۔ کسے نوں اوہ پھاہے لاندا تے کسے نوں بھکھے خون خوار جانوراں اگے سٹ دتا۔ کسے دے ہتھ پیر کٹ دیندا تے کسے دیاں اکھاں کڈھ دیندا۔ اک سپاہی نے بادشاہ دے ظلم دے خلاف آواز چکی تاں بادشاہ نے اوس نوں مارن دا حکم دے دتا۔ اوہ سزا توں بچن لئی اپنے گھروں نسیا تے جنگل وچ جا کے لک گیا۔ بادشاہ نے سپاہیاں نوں جنگل جا کے لبھن تے گرفتار کرن دا حکم دتا۔ سپاہی اوس نوں گرفتار کرن لئی جنگل جاندے نیں۔ پر اگوں اوہناں نوں شیر ملدا اے جو گرج دار آواز وچ بول رہیا سی۔ سپاہی ایہہ ویکھ کے  ڈر جاندے نیں تے اوتھوں واپس بادشاہ کول آ جاندے نیں۔ جدوں سپاہی نے اوہناں نوں واپس جاندے ویکھیا تاں اوہ لکی ہوئی تھاں توں باہر آیا۔ اوہ وی شیر نوں ویکھ کے  بہت خوف زدہ ہوندا اے۔ جدوں اوس غور نال آواز سنی تاں اوس نوں لگیا کہ شیر کسے مصیبت وچ اے۔ سپاہی جدوں شیر دے نیڑے ہویا تاں شیر نے اوس نوں کجھ نہ آکھیا، ہمت کر کے سپاہی شیر دے ہور نیڑے ہویا تاں اوس ویکھیا کہ اک تیر شیر دی لت وچ کھبیا ہویا اے تے تیر لگن پاروں لہولہان اے۔ سپاہی نے ہمت کر کے پہلاں شیر دی لت وچ تیر کڈھیا جس پاروں اوہدی پیڑ کجھ گھٹ گئی۔ مڑ اوس نے اوہدے پیر وچوں کنڈا کڈھیا۔ شیر اوس دی ایس رحمدلی تے انسان دوستی توں بہت متاثر ہویا اوس دے پیر چمے تے لنگر ہندا ہویا جنگل ول...

The Problems Faced by a Translator

Translation is a separate genre and should be treated as one with its specie set of issues, nuances and problem. The Islamic scholars face a peculiar set of problems as their root-medium is Arabic and it is from Arabic to the other languages--- that conversion words a translators' main job are hard to find. The following article is an effort to highlight the set of problems and issues faced by Muslim non-Arab translators while dealing with the medium of Arabic language.

Oil Discovery in Uganda and its Impacts on Poverty and Inequality: A Computable General Equilibrium Model Analysis

Discovery of natural resources like oil in developing countries has mixed impacts on the economy. At best, it is positive, at worst negative and in the middle, insignificant or none at all. Such mix up in the impacts has been explained empirically in terms of technical challenges in fiscal, monetary and other decisions. Utilizing a Computable General Equilibrium model and the Uganda Social Accounting Matrix 2007, this study attempts to establish the possible impact of the country’s oil on households. Three simulations are performed on production, absorption and export of oil. Thereafter, the results are analyzed using Distributive Analysis Statistical Package (DASP) software to establish their effects on households’ poverty, inequality and welfare. Generally, the simulations show that the discovery reduces both poverty and inequality. Specifically, in comparison to the baseline simulation, oil production, absorption and exports reduces absolute poverty, poverty gaps and severity. Further, the simulation results show that production, absorption and export reduce the Gini coefficient, implying a reduction in inequality. Other measures of inequality, notably Thiel L, T and S produce similar results and conclusions across simulations like that of the first measure. In the context of welfare, we note that the Hoover Index, and other welfare measures such as HI, TL and TT show significant changes. These measures show an improvement in households’ welfare for production, absorption and exports. The equivalent variation of individual households shows a positive effect on welfare except the urban farm households. By and large, the findings confirm the spillover effects of oil on all sectors of the economy with the exception of manufacturing and services. Further, we observe a positive impact of all the simulations on GDP, calculated by expenditures approach, exports, imports and private consumption; whereas a negative effect is noted for GDP, calculated by income and output approach, investment, government surplus and balance of payment position. This study recommends the managers of the economy to pay special attention to inject a reasonable portion of oil rent in those sectors which positively contribute to the economy, diversify the non-oil exports and above all boost private consumption.
