A series of field experiments were conducted at the research farm of The University of Agriculture Peshawar, Khyber Pakhtunkhwa, Pakistan during 2009-10 and 2010-2011, to investigate the effects of different tillage practices and sowing methods on productivity of wheat and mungbean cropping system on silty clay loam soil. The factors consisted of tillage practices i.e. tine cultivator twice plowed (TC2), chisels plow followed by rotovator (CR), mouldboard plow followed by rotovator (MR) , disk plow followed by rotovator (DR) and tine cultivator followed by rotovator (TCR) in the main plots and sowing methods i.e. sowing with single box seed drill (SD), combined drill (CD) and broadcast (BC) in the sub plots. The performance of different tillage implements during seedbed preparation in term of soil depth of cut, wheel slippage, fuel consumption and effective field capacity were statistically significant. Maximum soil moisture content at 20 and 40 cm depth recorded with CR and MR tillage practices, while maximum soil bulk density, soil penetration resistance, at 20 and 40 cm depth, fresh and dry weed biomass were obtained in plots tilled with tine cultivator twice (TC-2). However, minimum soil penetration resistance and fresh/ dry weed biomass were obtained in plots of CR and MR tillage practices, respectively. Higher soil moisture content at 20 and 40 cm depth was observed when sowing was done with seed drill and combined drill, respectively. Data regarding wheat crop indicated that higher number of tillers m -2 (403) and grain yield (4.6 t ha -1 ) were obtained in plots tilled with disk plow followed by rotavator. Similarly, maximum biological yield (10.4 t ha -1 ) was recorded in plots that were tilled with mouldboard plow followed by rotavator. Sowing by combined seed drill resulted in higher emergence, number of tillers, straw yield and biological yield. Similarly, higher number of grains spike -1 , spike length, grain yield and harvest indices were recorded when sowing was done with seed drill. Maximum total nitrogen in soil was noted in plots tilled with tine cultivator followed by rotavator. Similarly, sowing by seed drill and combine drill recorded greater total nitrogen in soil and wheat straw. The data relating to mungbean crop indicated that chisel plow followed by rotavator resulted in higher soil moisture content at 20 and 40 cm depths, higher emergence m -2 , plant height, pod length and total nitrogen in grains. Plots tilled with tine cultivator twice delayed flowering and maturity, increase in fresh and dry weed biomass, soil bulk density at 20 and 40 cm depth and soil penetration resistance at 20 and 40 cm depths. Number of branch plant -1 , pods plant -1 , biological yield, soil total nitrogen were higher in plots tilled with moldboard plow followed by rotavator. The maximum grain yield of mungbean and soil organic matter were recorded in plots tilled with tine cultivator followed by rotavator. Similarly, maximum harvest indices and total nitrogen in straw were recorded in plots tilled with disk plow followed by rotavator. Higher emergence, plant height, pod length, hundred grain weight, grain yield, biological yield, harvest xxiindices, total soil nitrogen, and total nitrogen in mungbean grain and straw were recorded in plots sown with seed drill. Plots sown with broadcast method delayed flowering and maturity, increase fresh and dry weed biomass and greater soil bulk density at 20 and 40 cm depths. Number of branch plant -1 , pods plant -1 , soil organic matter and total nitrogen in soil were greater in plots that were sown with a combined seed drill. Economic analysis of wheat and mungbean showed that maximum net revenue of wheat was obtained with mouldboard plow followed by rotavator (MR) tillage practices and the highest net revenue of mungbean was found with tine cultivator followed by rotavator (TCR) while minimum net revenue were obtained with tine cultivator (TC-2). Similarly, sowing by seed drill (SD) and combine drill (CD) resulted in maximum net revenue as compared to broadcast (BC) sowing method. It is concluded from the studies that all tillage implements when followed by rotavator for seedbed preparation resulted better yield and net economic revenue from wheat and mungbean crops as compared to the sole used of tine cultivator plowed twice. Similarly sowing by seed drill and combined drill showed a higher grain yield and net revenue than broadcast methods.

Understanding and Promotion of Civic Behavior Among Students in the Light of Sīrah

Civic behavior reflects the values related to individual’s attitude towards family, peer group, and neighborhood and includes the way one behaves in the society and community as a whole. The purpose of the present study is to describe what civic behavior is, its characteristics, its status in the Hadith, and the way forward for improvement of the civic behavior as guided by Sīrah of the Holy Prophet (ﷺ). Study implies that truthfulness, mercifulness, polite talk, helping others, respect for others, caring and sharing and promise-keeping, loyalty, sympathy, honesty, kindness, brotherhood, cooperation, fairness and unity are the core qualities that make the individual a civilized and active citizen and our Holy Prophet (ﷺ) is the embodiment of all these virtues. Descriptive approach was followed to explain and analyze the concept. First the concept of civic behavior was interpreted, then its importance and characteristics were discussed. After that it was explored in the light of the teachings of the Quran and the Prophet Muhammad (ﷺ). The findings highlight that the civic behavior in its best form was preached and practiced by the Holy Prophet (ﷺ) and his companions. Each dimension was interpreted in the light of the Quran and the Sīrah. It was concluded that Sīrah of the Holy Prophet (ﷺ) is an immaculate source of guidance and inspiration for not only Muslims but also for the whole mankind in acquiring the core values and abilities that determine the Civic behavior of an individual which ultimately results into a well-organized, peaceful and civilized society The study suggests that civic behavior of the citizens has significant impact on the formation and development of a peaceful society. It is recommended that civic behavior as reflected in the life of and practiced by the Holy Prophet (ﷺ) should be promoted and practiced for achieving a civilized social setup.

Microbial Strain Development for Hyperproduction of Β–Glucosidase Through Γ–Rays Mutagenesis and Expression Cloning

The cellulose enzymatic hydrolysis is carried out by the synergistic action of cellulase enzyme complex, namely endo-glucanase, exo-glucanase and β-glucosidase (BGL). BGL is responsible for the regulation of the cellulolytic process as both endo- and exo-glucanase activities are often inhibited by cellobiose. In recent years, interest in BGL has gained momentum, owing to its potential use in various biotechnological processes including biomass degradation, fuel ethanol production, release of aromatic residues, extraction of fruit juices, production of fermented foods etc. A. niger is by far the most efficient BGL producer among the microorganisms investigated. To cope with the current industrial demand it is necessary to produce BGL with improved catalytic and kinetic properties. The current report deals with the development of A. niger strain through gamma rays treatment. Hyper producer mutant M-6 was selected on the basis of 2-deoxy-D-glucose resistance, which showed about two fold higher production of BGL as compared to control. Both the parent and mutant had shown best results with 3% wheat bran at 30 °C and pH 5. Random mutagenesis resulted in mutations within the BGL gene sequence, leading to overall conformational change in BGL secondary structure. The subunit and native molecular mass of the BGLs from parent and mutant were same i.e. 130 and 252 kDa, respectively. LC-MS/MS analysis also confirmed the identity of protein bands as BGL from both strains with a slight difference in molecular masses. The mutant BGL proved to be 1.6 fold efficient for cellobiose hydrolysis with lower activation energy (Ea) and thermodynamically more stable against denaturants than parent BGL. The mutant BGL gene was also expressed in Pichia pastoris and the recombinant BGL possessed similar characteristics as that of the mutant BGL. Effect of metals on parent and mutant BGLs showed that Ca2+ decreased the Ea, resulting in efficient formation of ES*-complex as compared to apo-BGL, while, Mn2+ decreased the Ea at lower metal concentrations only. The heat of ionization for the acidic and basic limbs of the apo- BGL reduced significantly in the presence of Ca2+ and Mn2+. The turnover (kcat) of apo-BGL showed an increase in the presence of low concentrations of Ca2+ and Mn2+. The BGL activation mechanism by Ca2+ was of mixed nature where Ca2+ was preferably binding with free enzyme, while Mn2+ was preferably binding with ES*-complex rather than free enzyme (partially un- competitive). Ca2+- and Mn2+- bound BGL also showed higher thermo-stability as compared to apo-BGL. Immobilization of BGL through entrapment on latex and silicone resulted in an increase in optimum temperature and thermal stability than the free enzyme. The immobilized BGL also increased the cellulose hydrolysis rate with more than 70% functional stability after multiple reuses. The current study has resulted in a highly stable and catalytically active BGL enzyme which may have substantial applications in biofuel and biorefinery industries.
