Nitrogen Application Enhances the Radiation Use Efficiency and Quality of Cotton (Gossipum Hirsutum L.) Under Divergent Agro-Ecological Conditions of Pakistan

Cotton being a cash crop plays a pivotal role in the economy of Pakistan. Climate change has a pronounced impact on radiation use efficiency and quality of cotton fiber. To find out how nitrogen affected the radiation use efficiency and fiber quality of cotton cultivars in Punjab, a field study using a split-plot design was carried out. The study under representation was conducted in three different locations over the course of two years (2016 and 2017): Adaptive Research Farm in Dera Ghazi Khan, The Regional Agriculture Research Institute, Bahawalpur and The College of Agriculture, University of Sargodha. Three cotton cultivars viz., FH-Lalazar, FH-142, and MNH-786 were treated to six different nitrogen levels (0, 60, 120, 180, 240, and 300 kg ha-1) at each of the experimental location. The data collected from the experiments were used as input to run the CROPGRO-model. Input data from 2016 and 2017 were used to calibrate the CROPGRO-cotton model, and its evaluation involved comparing the simulated and observed values. This model accurately predicted radiation use efficiency, cotton fiber quality, and nitrogen impact on three cotton cultivars. For cotton productivity, the arid climate of Bahawalpur is far superior to the semi-arid climates of Sargodha and Dera Ghazi Khan, Pakistan

Evaluation of Cotton Advanced Lines/Varieties for Genetic Diversity and Correlation Studies of Cotton Leaf Curl Virus Disease with Yield Contributing Traits in Cotton

Plant genetic diversity aids in the creation of new varieties that are more resistant to pests and unfavorable climatic conditions. In order to discover varied parents and assess their cross-performance, the current study was carried out. The findings showed a substantial positive connection (0.81) between green bolls, plant height (0.57), and open bolls, as well as a significant positive correlation (0.52) between open bolls. On the other hand, a highly significant negative connection was discovered between the number of open bolls (-0.59), number of green bolls (-0.72), plant height (-0.78), and major stem nodes (-0.70) for the cotton leaf curl viral disease. Principal component analysis (PCA) showed that PC-I and PC-II accounted for 66.6% of the total variance. Plant height and green bolls were found to be positively correlated by PCA biplot analysis, but main stem nodes and open bolls showed a negative link, particularly with cotton leaf curl virus diseases. Based on cluster analysis, genotypes were divided into four clusters. Of these, Cluster-IV stood out because to its strong resistance to the cotton leaf curl virus disease and high yield, making it a good candidate for further breeding efforts. Other clusters include Mac-07, MNH-875, CRP-257, Super Okra, MNH-Super Gold, and GT/Bt Okra. The research emphasizes how crucial it is to use a variety of statistical methods to evaluate genetic diversity and support improved breeding practices. The knowledge that is derived will be useful in creating hybrids for upcoming breeding programs

Population Fluctuation of Bemisia Tabaci (L) and its Associated Predators under Combined Effects of Sowing Date and Varieties

The sowing date is very crucial among agronomic techniques for ensuring productivity and controlling insect pest. In 2018 and 2019, sowings were carried out 15 days intervals, starting on March 1 and ending on June 16. The dates were: March 1, March 16, April 1, May 1, May 16, and June 1. On advanced cultivars of Bt cotton, namely MNH-1026, MNH-1050, and IUB-13, the whitefly, Bemisia tabaci (Aleyrodidae: Hemiptera), and beneficial/predatory fauna were researched (control). The statistical analysis was multivariate. The relationship between the predatory fauna and the prey (whiteflies) in the correlogram was favourable. Predators showed a positive association with whitefly (0.592), boll weight (0.681), boll number (0.872), and seed cotton production (0.886) per acre, in that order. It was determined through Principal Components Analysis (PCA) that PC1 had an Eigen value \u3e1 and accounted for 79.3% of the overall variation due to the greatest positive loading vectors. It was determined that because late planting had a short growing period, whiteflies attacked it less frequently. It was determined that short-season crop cultivation and the breeding of resistant germplasm are advantageous in the face of climate change

Estimation of Genetic Diversity among Canola Accessions using Simple Sequence Repeat Markers

Genetic studies through molecular markers proved important to find out the genetic diversity of canola. In this study, 50 lines of canola were used to find the polymorphism using 15 SSR primers and investigated the genetic diversity, PIC values, frequency-based genetic distance, and allelic frequencies. Mean gene diversity, frequency-based genetic distance, and PIC values were 0.8777, 0.233 and 0.8666, respectively for the canola lines. A good range of genetic diversity was found among studied canola lines with value 85.91% polymorphism. Maximum and minimum genetic distances among 50 lines were 1 and 0.26, respectively. Accessions ACC-26068, ACC-24241, ACC-24244, ACC-24233, ACC-24423 and ACC-24224 have maximum genetic distance. Accessions ACC-24879 and ACC-24169 had minimum genetic distance i.e., 0.26. Dendrogram based on genetic distances showed four main clusters that were further dividing into several sub-clusters. The primers utilized in the present study, were valuable to identify different accessions of canola to find the variability present. This variability will be helpful to initiate the breeding program with their molecular genetic basis

A Review on Ov view on Overcoming Dual Challenges for Maiz coming Dual Challenges for Maize Cropping under High Plant Density: Stalk Lodging and Kernel Abortion

Increased optimal plant density is necessary in ensuring future food security by increasing crop productivity. However, maintaining relatively high plant density has to overcome two challenges i.e. kernel abortion and stalk lodging. The response of maize to increased plant density and the effects of increased plant density on maize productivity were discussed in this research. Increased plant density induces increased plant height, causes low photosynthetic capacity, limits the carbohydrate supply and increases kernel abortion. Also, increased plant density incurs a high risk of stalk lodging due to increased ear height and diminished stem diameter associated with reduced vascular bundles that provide, mechanical force. This review proposes a potential capacity of sucrose storage in stalk for tackling kernel abortion and stalk lodging. The mechanisms of boosting stem sugar storage with more efficient unloading, transporting, and storage in internodes are discussed

Patient Adherence and Elimination of Helicobacter Pylori Infection with Once-Daily Triple Therapy Versus Traditional Triple Therapy: A longitudinal study

Aim: To assess the patient Adherence and Elimination of Helicobacter pylori Infection with Once-Daily Triple Therapy versus Traditional Triple Therapy Study design: A longitudinal study Place and Duration: This study was conducted at Pir Abdul Qadir Shah Jeelani Institute of Medical Sciences Gambat Pakistan from Faburay 2020 to February 2021. Methodology: A total of 159 patients with aggressive peptic ulcer disease were checked positive for rapid urease exam or 13C-UBT had been provided either once-daily (Tinidazole 1000 milligrams + Azithromycin 500 milligrams +Rabeprazole 40 milligrams) or twice-daily (Amoxicillin 1000 milligrams +Clarithromycin 500 milligrams +Esomeprazole 40). The fast urease exams with 13C-UBT were performed ten weeks following the end of the medication. Pill counting, standardized surveys, and interviews were used to assess compliance and side effects. Results: When compared to the twice-daily cohort, patient adherence was shown to be higher in the once-daily cohort (84.8 percent) (68.8 percent) respectively. Meanwhile, 74.6 percent of the participants tested negative for H. pylori following therapy with the once-daily prescription and reported symptomatic improvement. The standard regime, on the other hand, resulted in 68.7% of the individuals testing negative to UBT and symptomatic alleviation (p=0.4063). Conclusion: No statistically substantial variation in elimination frequencies between the two regimes was observed. The once-daily prescription, on the other hand, had improved drug adherence than the standard treatment plan, indicating that it could be a secure and a superior tolerated substitute to traditional triple treatments, particularly for patients who do not adhere to the regimen. To corroborate the findings, more research should be done. Keywords: peptic ulcer disease, adults, helicobacter pylori, azithromycin</jats:p
