Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

Optimization of Phosphorus Application Rate on Maize Under Agro-ecological Condition of Urozgan: Optimization of Phosphorus Levels

Phosphorus plays a vital role in crop growth and productivity, thus a field experiment entitled (optimization of phosphorus application rate on maize under agro-ecological condition of Urozgan) was conducted at Urozgan Higher Education Institute research farm, during spring season of 2023 to evaluate the effects of various doses of phosphorus on maize growth and yield. Treatments were consisted of four levels of phosphorus 20, 40, 60, 80 Kg P2O5 ha-1 and control, the experiment was laid out in randomized complete block design and replicated thrice, the data was analyzed by IBM SPSS 24. Phosphorus application significantly influenced maize growth, yield and yield attributes compared to control, while the phosphorus doses increased from 20 to 80 kg P2O5 ha-1, crop growth, yield, and yield attribute were continuously increased. It can be concluded from the result of experiment that application of phosphorus under agro-ecological condition of Urozgan can increase crop growth, yield and yield attributes

Effect of Phosphorus Fertilizer and Seed Rates on Growth and Yield of Common Bean (Phaseolus Vulgaris L) in Kunduz, Afghanistan

A field experiment was conducted on the Effect of phosphorus fertilizer and seed rates on the growth and yield of common bean (Phaseolus vulgaris L) at the Farm of the agriculture faculty of Kunduz University during the spring season of 2023 to determine the optimum rates of phosphorus fertilizer and seed rates for maximum yield of common bean in the northeast of Afghanistan (Kunduz province). The treatment consists of three phosphorus levels (0kgP2O5ha-1, 40kgP2O5ha-1 and 80kgP2O5ha-1) and four combined seed rates (125 kgha-1, 150 kgha-1, 175 kgha-1 and 200 kg ha-1) laid out in randomized complete block design (RCBD) with three replications. The results revealed that phosphorus levels and different seed rates significantly affected on growth,  yield attributes and yield of common bean on plant height, Leaf area/plant (cm2), Brunches/plant, Root dry weight/plant(g),  Nodules/pant, No. of notes/plant, Pods/plant, Seeds/pod, 100 seed weight, seed yield/plant(g) and Grain Yield t/ha, the highest plant height (44.10cm), Leaf area/plant (217.18cm2), Brunches/plant(11.75), Root dry weight/plant (2.282g),  Nodules/pant (12.16),  Leaves/plant (47.833), No. of notes/plant (7.88), Pods/plant (16.98), Seeds/pod (6.97), 100 seed weight(34.536), seed yield/plant(8.83g) and Grain Yield (2.20t/ha) was in treatments 80kgP2O5ha-1 respectively. Seed rates were also significantly affected in treatment 200 kg ha-1 except for harvest index; all other yield attributes and yield was significant; the highest yield attributes and yield was in seed rate 200 kg ha-1. Thus 80kgP2O5ha-1with 200 kg ha-1 was found to be the best combination under northeast of Afghanistan agro-ecology as it gave higher values for yield and most yield related traits

Effects of phosphorus application on bunch and spreading genotypes of groundnut

Farm of Afghanistan National Agricultural Sciences and Technology University (ANASTU), Kandahar, Afghanistan to find out most suitable groundnut variety and their phosphorus levels in the study region. The treatments combination was of two groundnut varieties (Kormaki and Paparri) and four levels of phosphorus as P2O5 (P0= 0 kg P2O5 ha-1, P1=40 kg P2O5 ha-1, P2= 60 kg P2O5 ha-1 and P3= 80 kg P2O5 ha-1), were tested in a split plot design. Result revealed that Paparri variety produced significantly higher growth attributes (plant height, dry matter accumulation and number of main branches plant-1) and yield attributes (number of pods plant-1, pods dry weight plant-1, 100 kernel weight and shelling percentage) over Kormaki variety. Likwise, paparri variety produced significantly higher pods yield, kernel yield, haulm yield and biological yield over kormaki variety. In the like manner, significantly higher gross return, net return and benefit cost ratio was recorded from Paparri variety, whereas residual nitrogen was found significantly higher in kormaki variety. Among phosphorus levels, 60 kg P2O5 ha-1 recorded higher values for growth parameters, yield attributes viz. number of pods plant-1, pods weight plant-1, 100 kernel weight and shelling percentage, and yields (including pods yield, kernel yield, haulm yield and biological yield)
