  The study was conducted to determine the effect of plant spacing on forage yield, yield components and quality of Mott elephantgrass at the Agronomic Research Area of Agronomy (forage production) Ayub Agricultural Research Institute Faisalabad. Mott grass was sown at 45x45 cm, 60x60 cm, 75x75 cm, 90x90 cm 105x105 cm and 120x120 cm spacing (inter row and intra row spacings). Among the different spatial arrangements the first three spacings i.e. 45x45 cm, 60x60 cm and 75x75 cm proved to be more productive, appropriate and acceptable ones. Plant spacing 45x45 cm gave significantly the maximum forage yield t ha-1, fat %, protein content and digestibility against the minimum at 120x120 cm spacing under the agro-ecological conditions of Faisalabad (Pakistan).

  The main objective of present study was to determine the effect of different levels of nitrogen and plant spacings on yield of Mott grass (Pennisetum purpareum schum) at different cuttings. Plant spacings (inter row and intra row spacings) are S1 = 45 x 45 cm, S2 = 60 x 60cm and S3 = 75 x 75 cm and nitrogen levels included N0 = 0 (control), N1 = 100 kg, N2 = 200 kg, N3 = 300 kg and N4 = 400 kg ha-1. Production potential of Mott grass was determined on the basis of green fodder and dry matter yield. Application of N at different plant spacings increased both green fodder and Dry matter yield significantly over control in all the three cuttings. Crop fertilized at 300 kg N ha-1 produced the maximum green fodder yield 509 t ha-1 and Dry matter yield (97 t ha-1) of all the three cuttings at the spacing pattern of 45 x 45 cm.

  Field experiments were conducted at the Field Station of the Water Resources Research Institute (WRRI), National Agricultural Research Centre (NARC), Islamabad and farmers fields at Hitter, Tehsil Fatehjang, district Attack of the Punjab province to study the benefits of supplemental irrigation on wheat crop under rainfed farming systems. Three irrigation strategies, namely 10 mm application at pre-sowing (Rauni), 10 mm application at 50 percent management allowed deficit (MAD) and 25 mm application at 75 percent MAD were employed. The supplemental irrigations were applied using locally developed raingun sprinkler irrigation systems. The yields of wheat grain and straw were increased with the application of supplemental irrigation at all the three selected strategies. Highest water use efficiency of 20.55 and 24.07 kg/mm of water was obtained at NARC, Islamabad and Fatehjang locations during the driest years of 1993-94 and 1992-93, respectively. The highest net benefits of around Rs. 9000 were obtained with irrigation strategy of 25 mm application at 75 percent MAD at both the locations. However, the economic irrigation strategy was a pre-sowing irrigation of 10 mm only, where highest benefit-cost ratio was observed. Therefore, scheduling programme must be designed in a way to apply deficit irrigations to plant crop at optimal planting time and to avoid effects of dry spells on reduction in yield or crop failures. The depth of irrigation application must be in accordance with the stage of growth. Furthermore, economic priority must be linked with the irrigation priority for developing management strategies.

  The present investigation was an effort to explore the nutritional profile and antioxidant indices of vitamin K dietary sources i.e., spinach and soybean. For the purpose, spinach and soybean were nutritionally characterized with special reference to vitamin K content. The proximate composition of spinach exhibited that moisture, crude protein, crude fat, crude fiber, ash and Nitrogen Free Extract (NFE) as 90.71±4.14, 2.03±0.95, 0.32±0.007, 0.58±0.02, 1.24±0.06 and 5.01±0.11%, respectively. However, tested soybean indicated the values respective traits as 8.96±0.45, 32.28±1.99, 18.64±1.02, 2.93±0.16, 3.38±0.19 and 33.79±1.15%. Furthermore, spinach showed good mineral profile dominated by magnesium, potassium and calcium whilst soybean is abundant in potassium, zinc and magnesium. The HPLC quantification of vitamin K revealed that spinach contained 379.09 μg/100g phylloquinone as compared to soybean 29.79 μg/100g. Amongst antioxidant extracts, methanolic extracts of spinach and soybean showed higher total phenolic, DPPH scavenging and antioxidant activities. In conclusion, spinach showed higher antioxidant status and phylloquinone as compared to soybean however, soybean contained ample amount of protein and fat contents.

  Background and Objectives: Diabetic Foot Ulcers (DFU) are most frequent foot abrasion which leads to lower extremity amputation. Diverse microbes are associated with DFU infections which make treatment difficult due to their strong resistant nature. Bacterial resistance is being linked with the production of beta-lactamases, expression of resistant genes and there is also strong correlation of virulence factors etc. Keeping in view the significance of Gram-negative pathogens association with DFU patients and their antibiotic resistance mechanisms, current study was designed to elaborate Gram-negative resistant bacteria for their resistant mechanisms and linkage with virulence as it may have some strong correlation with resistance. Materials and Methods: Gram-negative bacterial isolates (n = 37) that have proven resistance against various drugs through simple disc diffusion method were subjected for detection of Extended-Spectrum Beta-Lactamases (ESBL), Metallo-Beta-Lactamases (MBL) and AmpC-Beta-Lactamases. Further these isolates were subjected for detection of CTX-M beta-lactamase genotype. Further all Gram-Negative bacterial strains were screened for evaluation of their virulence factors. Results: In this study total of (n = 37) where Pseudomonas aeruginosa was the dominant bacteria followed by Escherichia coli and Klebsiella pneumoniae. The prevalence of beta-lactamases were as AmpC (72.5%) the most prevalent one, followed by MBL (67.5%) and ESBL incidence was (59.5%). Higher incidence of beta-lactamases were found in Pseudomonas aeruginosa. Conclusion: The severity of resistance in Gram-Negative bacteria to multiple antibiotics may be due to the co-production of beta-lactamases along with virulence factors that could be the leading cause of bacterial pathogenesis in such patients.
