Rice (Oryza sativa L.) feeds to two-third of the global population by serving as staple food. It is the main export commodity of several countries; thus, contributes towards foreign exchange earnings. Unfortunately, average global rice yield is far below than its genetic potential. Low nitrogen (N) use efficiency (NUE) is among the major reasons for low average yield. Current study evaluated the impact of nitrogen fertilizer application methods (conventional and deep placement) on growth, yield-related traits, chlorophyll contents, photosynthesis rate, agronomic N-use efficiency (ANUE), partial factors productivity of applied N (PFP) and economic returns of two different transplanted rice varieties (Basmati-515 and Super-Basmati). Fertilizer application methods significantly affected allometry, yield-related traits, chlorophyll contents, photosynthesis rate, ANUE, PFP and economic returns. Deep placement of N-fertilizer (DPNF) observed better allometric traits, high chlorophyll contents, photosynthesis rate, ANUE, PFP, yield attributes and economic returns compared to conventional application of N-fertilizer (CANF). Similarly, Basmati-515 had better allometric and yield-related traits, chlorophyll contents, photosynthesis rate, ANUE, PFP and economic returns than Super-Basmati. Regarding interactions among N-fertilizer application methods and rice varieties, Basmati-515 with DPNF resulted in higher chlorophyll contents, photosynthesis rate, ANUE, PFP, allometric and yield related traits and economic returns than CANF. The lowest values of these traits were observed for Super-Basmati with no application of N-fertilizer. Both varieties had better yield and economic returns with DPNF compared to CANF. It is concluded that DPNF improved yield, ANUE and economic returns; therefore, should be opted to improve productivity of transplanted fine rice. Nonetheless, lower nitrogen doses need to be tested for DPNF to infer whether it could lower N use in rice crop.

Purpose Owing to aridity in our agro-ecosystem, mineralization of organic substrate is quite rapid and thereafter volatilized due to lower matrix affinity. In these consequences, the study has been chalked out with the hypothesis to alter the best approaches for mineralization of available organic resources as soil supplement to reduce the economic burden on the farming community. Our laboratory study showed the sequential temporal variations in physic-chemical properties of available organic substrates such as farm manure and sugar industry waste during composting/vermicomposting. Methods The organic material obtained from the farm manure of livestock farm and another sources of industrial organic waste {sugarcane baggase (SCB), pressmud (SPM), mixture of SCB, SPM and sugarcane effluent} were used for this mineralization perspectives. However, all organic substrates properties remained static except moisture up to a period of 21 days. Thereafter, these produced and processed matrix was subsequently composted and vermicomposted during 45 days under normal shade. No earthworms were spiked in composting while Lumbricus rubellus collected near vicinity of research area were inoculated at the rate of 50 g/kg of waste in vermicomposting. Contrarily, their applications was mandated as and when required policy subsequently. Moisture and temperature status of substrates were monitored regularly.

Vehicular emissions cause heavy metal pollution and exert negative impacts on environment and roadside vegetation. Wild plants growing along roadsides are capable of absorbing considerable amounts of heavy metals; thus, could be helpful in reducing heavy metal pollution. Therefore, current study inferred heavy metal absorbance capacity of some wild plant species growing along roadside. Four different wild plant species, i.e., Acacia nilotica L., Calotropis procera L., Ricinus communis L., and Ziziphus mauritiana L. were selected for the study. Leaf samples of these species were collected from four different sites, i.e., Control, New Lahore, Nawababad and Fatehabad. Leaf samples were analyzed to determine Pb2+, Zn2+, Ni2+, Mn2+ and Fe3+ accumulation. The A. nilotica, Z. mauritiana and C. procera accumulated significant amount of Pb at New Lahore site. Similarly, R. communis and A. nilotica accumulated higher amounts of Mn, Zn and Fe at Nawababad and New Lahore sites compared to the rest of the species. Nonetheless, Z. mauritiana accumulated higher amounts of Ni at all sites compared with the other species included in the study. Soil surface contributed towards the uptake of heavy metals in leaves; therefore, wild plant species should be grown near the roadsides to control heavy metals pollution. Results revealed that wild plants growing along roadsides accumulate significant amounts of heavy metals. Therefore, these species could be used to halt the vehicular pollution along roadsides and other polluted areas.

Numerous cropping systems of the world are experiencing the emergence of new weed species in response to conservation agriculture. Conyza stricta Willd. is being a newly emerging weed of barley-based cropping systems in response to conservational tillage practices. Seed germination ecology of four populations (irrigated, rainfed, abandoned and ruderal habitats) was studied in laboratory and greenhouse experiments. The presence/absence of seed dormancy was inferred first, which indicated seeds were non-dormant. Seed germination was then recorded under various photoperiods, constant and alternating day/night temperatures, and pH, salinity and osmotic potential levels. Seedling emergence was observed from various seed burial depths. Seeds of all populations proved photoblastic and required 12-hour light/dark period for germination. Seeds of all populations germinated under 5–30°C constant temperature; however, peak germination was recorded under 17.22–18.11°C. Nonetheless, the highest germination was noted under 20/15°C alternating day/night temperature. Ruderal and irrigated populations better tolerated salinity and germinated under 0–500 mM salinity. Similarly, rainfed population proved more tolerant to osmotic potential than other populations. Seeds of all populations required neutral pH for the highest germination, whereas decline was noted in germination under basic and alkaline pH. Seedling emergence was retarded for seeds buried >2 cm depth and no emergence was recorded from >4 cm depth. These results add valuable information towards our understanding of seed germination ecology of C. stricta. Seed germination ability of different populations under diverse environmental conditions suspects that the species can present severe challenges in future if not managed. Deep seed burial along with effective management of the emerging seedlings seems a pragmatic option to manage the species in cultivated fields. However, immediate management strategies are needed for rest of the habitats.

The major purpose of this study was to investigate “Relationship between Teachers Classroom Management Skills and Students Academic Achievements at Secondary level districts of Khyber Pakhtunkhwa,” All government secondary schools of southern district were constituting the population of the study and all teachers and students of the secondary schools were also included in the population of the study. From each district, eight schools were selected as a sample from which four schools were male and four schools were female. From each school, five teachers and 20 students were selected as a sample or respondents in this way 280 teachers and 1120 students were selected as a sample of the study. The sample of the study was finalized by using the John Curry formula. The collected data was entered into SPSS version 23 for treatment. According to the nature of the objectives of the study T. Test, Pearsons correlation was used.

Background: The gold standard treatment of acute appendicitis is appendectomy. Early surgery reduces a number of complications such as appendicular mass formation, abscess and perforation. However, diagnostic inaccuracy especially in female gender can lead to negative appendectomy because other gynecological diseases have quite similar presentation. The objective of our study is to determine the diagnostic accuracy of Alvarado scoring system in the diagnosis of acute appendicitis in comparison to the gold standard histopathology in patients with acute pain right iliac fossa. Methods: This descriptive Cross-sectional study was carried out on 253 patients with acute pain in right iliac fossa at Surgical Department of MTI, Lady Reading Hospital from 14th July 2020 to 14th January 2021. Results: Mean age was 37 years with standard deviation ± 10.09. 111(44%) patients were male and 142(56%) patients were female. 129(51%) patients were married while 124(49%) patients were unmarried. Based on Alvarado scoring Acute appendicitis was diagnosed in 197(78%) patients and missed in 56(22%) patients. Diagnosis of Acute appendicitis was confirmed by histopathology report in 245(97%) patients while in 8 (3%) patients histopathology did not reveal acute infection. Diagnostic accuracy of Alvarado scoring analyzed with histopathological diagnosis was 78.65%. Conclusion: Alvarado scoring has a sensitivity of 79.18%, specificity 62.5%, PPV 98.47%, NPV 8.92% and diagnostic accuracy of 78.65% in diagnosis of acute appendicitis taking histopathology as gold standard in patients with acute pain right iliac fossa.
