Integrated nutrient management (INM) approach can improve soil fertility on long term basis. The present study was conducted to determine effects of INM on quantitative and qualitative characters of two Safflower (Carthamus tinctorius L.) cultivars "Thori-78 and Leed-00". Five treatments using different composition of poultry litter, farm yard manure, nitrogen and phosphorous fertilizers with recommended dose as a control measure were replicated thrice in randomized complete design. The results of field trial depicted maximum plant height (174.6 cm), number of heads plant −1 (42.67), number of seeds head −1 (59.0), thousand seed weight (42.26 g), biological yield (3089 Kg•ha −1) and seed yield (455.2 Kg•ha −1) recorded from combined application of FYM @ 2 t•ha −1 and Half (N-P) (soil application) (T 5) in Genotype "Leed-00" which was statistically different from all other treatments. Thori-78 also showed increase in yield and yield components under the same treatment (T 5) i.e.2 t•ha −1 FYM and Half (N-P).No effect of INM was found on fatty acid composition of safflower cultivars. The correlation coefficients illustrated positive and significant association of seed yield with plant height (0.89), number of heads pod −1 (0.86) and number of seeds head −1 (0.83) as a result of application of selected treatment. These results demonstrated the significance of INM in safflower yield improvement under rainfed conditions.

We explored how simple bedside tests of attention, vigilance and visuospatial function might assist in identifying delirium in hospitalized patients. Performance on a battery of bedside cognitive tests was compared in elderly medical inpatients with DSM-IV delirium, dementia, comorbid delirium-dementia, and no neurocognitive disorder. 193 patients [mean age 79.9±7.3; 97 male] were assessed with delirium (n=45), dementia (n=33), comorbid delirium-dementia (n=65) and no neurocognitive disorder (NNCD) (n=50). The ability to meaningfully engage with the tests varied from 84% (Spatial Span Forwards) to 57% (Vigilance B test), and was especially problematic among the comorbid delirium-dementia group. The NNCD was distinguished from the delirium groups for most tests, and from the dementia group for the Vigilance B test and the Clock Drawing Test. The dementia group differed from delirium groups in respect of the Months Backward Test, Vigilance A and B tests, Global assessment of visuospatial ability and the Interlocking Pentagons Test. Overall, patients with delirium were best identified by three tests - the Months Backward Test, Vigilance A test and the Global Assessment of visuospatial function with failure to correctly complete any two of these predicting delirium status in 80% of cases. Simple bedside tests of attention, vigilance and visuospatial ability can help to distinguish neurocognitive disorders, including delirium, from other presentations. There is a need to develop more accurate methods specifically designed to assess patients with neurocognitive disorder who are unable to engage with conventional tests.

An experiment was conducted at PMAS Arid Agriculture University during Rabi 2007, to observe the allelopathic effect of water extracts of sorghum, sunflower and brassica to control weeds in wheat using cultivar GA-2002. Extracts were prepared by taking chopped dry sorghum, sunflower and brassica herbage separately in water for one day in the proportion of 1:10 (w/v). The treatments were control, hand weeding, sorghum, sunflower and brassica individually and combined as sorghum+ sunflower, sorghum+ brassica, sunflower+ brassica and sorghum+ sunflower+ brassica. The experiment was laid out in Randomized Complete Block Design with four replications. Size of each individual plot was 5 × 6 m. Results indicated that the highest weed density and biomass suppression was achieved with hand weeding among all the treatments. Among the foliar application of extracts, the highest weed...

Production of wheat as staple food is impinged due to increasing population, biotic and abiotic stresses like climatic events including increased temperature, droughts, floods and variability in rainfall pattern due to global warming. Climate is likely an acute driver of evolutionary changes in pathogen and host populations by interfering with host plant-pathogen interaction, population dynamics and gene expression. In this perspective, current study was designed to analyze wheat crop as host to explore the dynamics of foliar blight Alternaria triticina and Drechslera sorokiniana under varying climatic conditions on wheat growth, development and productivity for Islamabad region of Pakistan by comparing and evaluating two modeling methods, i.e. Statistical (R mo...

Significant differences were found among genotypes for grain yield plant-1, 100-seeds weight, seeds pod-1 and pods plant-1. Local Kashmir excelled all genotypes in grain yield (24.5 g plant-1) while minimum yield (1 g plant-1) was also produced by indigenous cultivar Local Balakot. Exotic cultivars differ significantly for grain yield with maximum 11.4 g plant-1 for Ducato and minimum 1.2 g plant-1 in case of Varigated and 2a-(GB 44004.1-1999). Non significant differences among genotypes were observed for days to maturity. The correlation coefficients illustrate the positive and significant association of grain yield with flowering duration, number of pods-1, and number of seeds plant-1, therefore, these traits should be considered for genetic improvement through selecti...
