No full textDespite the lack of artistic maturity, early tradition of Urdu Novel had diverse colors. In this tradition Lakhnavi' novelists took great pains in presenting the life and social mobility. Abdul Haleem Sharar's Firdaus-e-Bareen is the interesting and well written artistically. In this article three distinct and salient feature of the novel are discuss, i.e. fictionalization of history, maximalist style and film like scenes. These features belong to the novel's art. Urdu critics have not pondered over these feature before

No full textAgriculture needs a reduced dependency on synthetic chemical fertilizers and renewable biomaterials to add nutrients to soil, ameliorating degraded soil and gaining agronomic yield of crops. Biochar mixed with inorganic fertilizer has been effective in improving the crop yield. However, the influence of composite biochar (C-BC) obtained from poultry feathers (PFs), cow bones (CBs), and rice straw (RS) waste streams as sources of N, P, and K, respectively, is still unclear. This study aimed to unveil a tripartite relationship of biochar composite applications with soil properties and agronomic attributes of sunflower var. orisun. Biochars associated with nutrient acquisition were characterized through Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive x-ray (EDX) spectroscopy. To assess the bioavailability of nutrients and their impact on agronomic yield, a greenhouse trial was set up with sunflower, using each biochar individually as well as in composite application at three levels of amendments (0%, 2%, 4%, and 6% w/w) along with commercial fertilizer. The surface characterization through FTIR, SEM, and EDX of each biochar illustrated the presence of a wide range of functional groups, porosity, and multiple nutrients. C-BC showed a significantly positive response to soil properties and exhibited the high availability of nutrients (N, P, and K) in soil as compared to commercial fertilizer. Application of C-BC at 4% was found effective for dry biomass (47 g) and seed yield (35.16 g), resulted in oil and protein concentrations as high as 44.8% and 23.5%, respectively. Feather-derived biochar (PF-BC), bone char (CB-BC), and RS-derived biochar (RS-BC) in the form of biochar composite can become an applicable substitute for chemical fertilizer in sustainable agriculture
Freshwater hyphomycete spora of the River Ravi
No full textIn a study of the river spora of Ravi, Lahore, twenty-nine conidial species mostly belonging to freshwater hyphomycetes were recorded by four techniques from January to June, 1999. These species were recorded by filtration of water, sporulation on submerged plant material and trapping in natural or artificial foam. The natural foam provided the richest data on the river spora. A few species were observed colonizing the submerged plant material. The data obtained by direct filtration and artificial foam trapping was quite similar. Articulospora proliferata and Tetracladium marchalianum were the only species detected by all the four techniques
Variation in conidial concentration of freshwater hyphomycetes in a semi-tropical canal water habitat
No full textThe freshwater hyphomycete conidial numbers showed a characteristic pattern of fluctuation under the influence of temperature and biomass deposition in the Lahore Branch of the BRB canal. The conidial numbers showed a gradual increase from 2% in June to 39% in October. The clearing of the substratum from the canal in January played a significant role in the decline of conidial concentration from 13% in December to 6% in February. The total number of hyphomycete species showed an increase from 20 in April to 39 in December.

No full textEffects of Salinity Stress on Growth and Physio-biochemical Parameters of Three Pea (Pisum sativum L.) Cultivars of Different Maturity Duration
No full textBackground: Salinity is one of the leading abiotic stresses that negatively affects the growth of many important food crops and significantly reduces the productivity and yield value.Methods: The present study was conducted to study the effects of NaCl stress on three pea (Pisum sativum) cultivars (Climax, Lina Pak and Pea-267) of different maturity level (Late, early, and mid-season flowering) under In vitro conditions. Two weeks old In vitro grown shoots of three pea cultivars were subjected to stress condition in MS medium supplemented with five levels of NaCl (0, 20, 40, 80 and 100mM NaCl) for one month and different morphological and physio-biochemical traits including length of shoot, number of leaves, shoot biomass, chlorophyll, proline and total phenolic content, total proteins and non-enzymatic antioxidant (DPPH) activities were studied.Results: The results were analyzed using different statistical approaches (ANOVA, MNOVA, PCA, correlation and regression) to identify the tolerance level of each genotype. Shoot length and shoot fresh weight were increased at 20 and 40mM in Climax, while proline content progressively increased with an increase in stress concentration in all the genotypes. Total protein content increased in cvs. Climax and Pea-267 and decreased in Lina Pak above 20mM and DPPH was increased in Climax and Pea-267 at 20 and 40mM, while in Lina Pak it showed an increase at only 20mM NaCl concentration. According to the results of MNOVA and regression analysis, significant changes occurred in biomass, proline content and DPPH values. A strong positive correlation of shoot dry weight was found with total phenolic and proline content. Maximum value of stress tolerance index was recorded for Climax.Conclusion: Biplot analysis clustered cvs. Climax and Pea-267 cultivars into tolerant group and Lina Pak in sensitive group based on the mean performance of studied parameters to NaCl stress and control treatments
