Management of inorganic fertilizer is very important to obtain maximum crop yield and improved nutrient use efficiency in cereal crops. Fixation of phosphatic fertilizers in alkaline soils due to calcareousness is one of the major hurdles. It induces phosphorus nutritional stress that can decrease the yield of maize and wheat. Selection of a suitable application method and proper stage of crop for phosphorus (P) fertilizer has prime importance in better uptake of P and crop production. Among different application methods, soil and foliar application are widely adopted. In wheat and maize, knee height + tasseling and stem elongation + booting are critical stages towards P deficiency. That is why field trials were conducted to evaluate the supplemental effect of foliar P on maize and wheat yields. For that, 144 mM KH2PO4 was applied as foliar at knee height + tasseling and stem elongation + boot stages in maize and wheat, respectively. Soil application of 0, 20, 40 and 60 kg P ha−1 was done through broadcast and band methods. Results showed that foliar spray of 144 mM KH2PO4 at knee height + tasseling and stem elongation + boot stages in wheat and maize significantly enhanced grains yield and phosphorus use efficiency (PUE) where P was applied as banding or broadcast at the time of sowing. A significant decreasing trend in response to increasing soil P levels validated the efficacious role and suitability of foliar P. In conclusion, the use of P as foliar at knee height + tasseling and stem elongation + boot stages is an efficacious way to manage P fertilizer.

We report an interesting and rare case of a man with adenomyomatous hyperplasia of the ampulla of Vater presenting as acute pancreatitis, which to our knowledge, is only the second reported case in the English literature. The patient presented with an acute onset of abdominal pain, nausea and vomiting, without fever, chills or rigours. CT of the abdomen revealed changes of acute pancreatitis with a peripancreatic adenopathy, and abdominal ultrasound revealed a slightly hyperechoic and oedematous head of the pancreas, consistent with acute pancreatitis. Endoscopic retrograde cholangiopancreaticography revealed an ampullary lesion. Pathology of the ampullary lesion revealed an inflammatory polyp. Endoscopic ultrasound with endoscopic mucosal resection of the lesion revealed an adenomyomatous hyperplasia. The patient recovered well postendoscopic resection without recurrent pancreatitis or cholestasis.

Oesophageal papillomatosis is a very rare entity, with only 10 cases (including ours) reported in the literature. We report a 51-year-old man with a 25-year history of dysphagia with solids and liquids who failed a trial of proton pump inhibitors and fluticasone. His initial endoscopy revealed a viliform mass with dense eosinophilic infiltrate without neoplasia. Endoscopic ultrasound examination revealed a 4×1.6×0.7 cm mucosal hemicircumferential lesion without regional adenopathy. Pathological findings from the oesophagectomy specimen confirmed oesophageal papillomatosis with no malignancy. Surveillance endoscopy 4 months later revealed the lesion had increased in size. Additional ablative therapies failed, and the patient underwent oesophagectomy. Surveillance CT of the chest and abdomen at 3 months and oesophagogastroduodenoscopy at 6 months were negative. This case illustrates that oesophageal squamous papillomatosis not amenable to medical therapy requires surgical treatment.

Poor soil fertility due to continuous depletion of micronutrients is a major problem for the production of Prunus domestica L. Low level of soil organic matter and calcareous parent material decrease the bioavailability of these micronutrients to plum plants. Thus, less micronutrients uptake resulted in deterioration of plum fruit quality and decreased yield. On the other hand, balance and correct combination of micronutrients used as a foliar has potential to overcome this problem. Foliar application method provides plants a chance for rapid and easy uptake of micronutrients. Therefore, the present research was carried out to select the best combination of micronu-trients using foliar method. Aim of the study was to select a balanced combination of micronutrients for better production and improved quality of plum (Prunus domestica L., variety Fazal manai) fruit. Seven treatments in three replications were applied. Our results showed that the quality of fruit was significantly improved through the application of T6 micronutrients consortia. A significant increase in total soluble solids (16%), fruit yield per tree (92%) and fruit size (12%) validated the effectiveness of treatment T6 (Zn + Cu + Fe + Mn + B = 0.5% + 0.2% + 0.5% + 0.5% + 0.1%) over control. Application of treatment T6 also enhanced quality attributes, that is, juice acid-ity (22%), juice sugar (22%) and juice contents (16%), as compared to control. It is concluded that use of treatment T6 as a foliar application is a better approach for significant improvement in quality and yield attributes of plum in micronutrients deficient conditions.

Increasing ambient ozone (O3) concentrations and resurgent rust diseases are two concomitant limiting factors to wheat production worldwide. Breeding resilient wheat cultivars bearing rust resistance and O3 tolerance while maintaining high yield is critical for global food security. This study aims at identifying ozone tolerance among key rust-susceptible wheat genotypes [Rust near-universal susceptible genotypes (RnUS)], as a first step towards achieving this goal. Tested RnUS included seven bread wheat genotypes (Chinese Spring, Line E, Little Club, LMPG 6, McNair 701, Morocco and Thatcher), and one durum wheat line (Rusty). Plants were treated with five O3 concentrations (CF, 50, 70, 90, and 110 ppb), in two O3 exposure systems [continuous stirred tank reactors (CSTR) and outdoor-plant environment chambers (OPEC)], at 21–23 Zadoks decimal growth stage. Visible injury and biomass accumulation rate were used to assess O3 responses. Visible injury data showed consistent order of genotype sensitivity (Thatcher, LMPG 6 > McNair 701, Rusty > Line E, Morocco, Little Club > Chinese Spring). Additionally, leaves at different orders showed differential O3 responses. Biomass accumulation under O3 stress showed similar results for the bread wheat genotypes. However, the durum wheat line “Rusty” had the most O3-sensitive biomass production, providing a contrasting O3 response to the tolerance reported in durum wheat. Chinese Spring was the most tolerant genotype based on both parameters and could be used as a source for O3 tolerance, while sensitive genotypes could be used as sensitive parents in mapping O3 tolerance in bread wheat. The suitability of visible symptoms and biomass responses in high-throughput screening of wheat for O3 tolerance was discussed. The results presented in this research could assist in developing future approaches to accelerate breeding wheat for O3 tolerance using existing breeding materials.
