Multi-Model Approach to Simulate the Growth and Seed Cotton Yield of Promising Cotton Cultivars at Different Planting Times and Deficit Irrigationunder Changing Licmate Scenarios
Adaptation has potential to overcome negative impact of climate change in future. Suitable cotton variety selection is imperative to cope with temporal variations and water deficit conditions for yield maximization and sustainability under unpredictable environmental conditions. Field experiments were conducted for promising cotton cultivars sown from 10-March to 21-June with 20 days interval and deficit irrigation regimes (full irrigation, 80% to 40% of full irrigation and rain-fed) for two growing seasons (2012 and 2013) consecutively. Different statistical approaches were used to analyze the data. Cultivar MNH-886 and NIAB-9811 (NIAB-Kiran) planted 30-March to 10-May produced significantly higher seed cotton and lint yield while NIAB-112 also performed reasonably well for late planting (1-June). However higher net monetary return was produced by 21-April planting reasonably well for all cultivars. Seed cotton, lint yield, fiber quality and water use efficiency were found higher with the application of 60% to 80% (565 mm to 645 mm) of full irrigation (720 mm). Water deficit of 20-40% comparative to conventional farmer practice could be used as an alternative deficit irrigation strategy without any significant reduction in cotton yield. CSM-CROPGRO-Cotton and AquaCrop-Cotton models were parametrized well with field data, models performed reasonably well during evaluation with reasonably good statistical indices as RMSE, d-index, MPD, nRMSE and R2 for phenology, growth, seed cotton yield and yield components within the growing years. It is expected that seasonal average temperature would rise 1.52ºC and 2.60ºC in RCP 4.5 and 1.57ºC and 3.37ºC in RCP 8.5 of twenty nine GCMs ensemble (29 GCMs) in near term (2010-2039) and mid-century (2040-2069), respectively as compared with baseline. Mean seed cotton yield would decrease by 8% and 20% in RCP 4.5 scenario, while 10% and 30% reduction would be expected in RCP 8.5 scenario in near term (2010-2039) and mid-century (2040-2069), respectively compared with the baseline (1980-2010). Cultivar NIAB-9811 and NIAB-122 showed lower reduction in yield under future climate scenarios hence these could be used for future cultivation and to develop climate resilient germplasm. Adaptation technology of 20 days earlier planting than current (10-May), 18% and 29% increase in planting density for spreading and erect type cultivars, 25% increase in nitrogen amount, 30% reduction in irrigation and 15% upsurge in genetic potential would reduce the negative impact of temperature and rainfall variability in mid-century climate (2040-2069).

This study aims to analyze the quality of quarantine services on ship crew satisfaction during the Covid-19 pandemic at the Belawan Sea port. This study is a quantitative study with a cross sectional method which aims to analyze the quality of quarantine services on satisfaction during the COVID-19 pandemic at the Belawan Sea Port using the ServQual approach which consists of physical evidence, reliability, responsiveness, assurance, and empathy. The results of the study are expected to provide input regarding the quality of quarantine services provided by the Class I Medan KKP to ship crews during the COVID-19 pandemic. Based on the ServQual analysis, the results show that the satisfaction of the crew of the quarantine service at Belawan Port is very satisfying with a suitability level of 107.56% (the average service / reality score is 4.00 and the expectation score is 3.72). It is suggested to improve coordination and more intensive advocacy with shipping agents as intermediaries between officers and skippers as crew so as to reduce the length of service waiting time, in order to increase the number of human resources carrying out document checks on board, involving female medical officers for health checks The crew who came from affected countries/ports to facilitate information retrieval, ordered the boarding officers to bring Personal Protective Equipment when interacting with the crew.
Sufism is recognized as an important mystical facet of Islamic history. The expansion of Islam is also indebted to Sufis who migrated to different regions with the universal message of Islam and they further established and developed various Sufi orders and schools of thought. Among the many orders that took root in the subcontinent, the Chishtiya order gained prominence and became conspicuous. Chishti Khanqahs or the dwellings of the Chishti Sufis were grounds of spirituality where a unique culture thrived. These abodes fundamentally altered the socio-religious history of the region. Hundreds of Chishti Dargahs all over India and Pakistan continue to work as independent living institutions even today.Much scholarly work has been produced on the Chishtiya Sufi order in the subcontinent and studies have been conducted to compare its teachings to those of different schools of Sufi thoughts in various times and ages. Researchers have also made in depth studies of the Khanqahi structure of Chishtiya order but little study has been made on the spiritual/Sufi practices at the Chishti Dargahs and the social, political, religious and economic role of these Dargahs in contemporary times. This research attempts to look at the Sufi practices at the two Chishti Dargahs in West Punjab, Pakistan. For this study the Dargah of Baba Farid Masud-ud-Din Ganj-e-Shaker in Pakpattan, Sahiwal and Khawaja Shams-ud-Din Sialvi in Sial Sharif, Sargodha have been chosen for their multifunctional role in the region. Both, Chishti Khanqahi and Dargahi structure are analyzed side by side as both are intertwined with each other. The study also comprehends the multifunctional character of Dargahs and studies the character of Khanqahs and their function and perpetual impact on the region of Indo-Pak subcontinent.The first chapter explores the historical role of the Chishtiya school of thought, its teachings and practices. It also discusses Chishti Khanqahs‘ function and their impact on the medieval Indian society. It attempts to trace Chishti Khanqahs‘ syncretistic tendencies that synthesize Indian art and culture with Muslim traditions. The chapter also tries to locate the reasons that make Chishti Dargahs a living institution in contemporary times.The second chapter locates Medieval Punjab as the first South Asian region to encounter the impact of early Sufi mystics. The research analyzes the sociocultural set up of the times and the role of Sufi Khanqahs/Dargahs such as that of Ali bin Usman Hajviri‘s, commonly known as Data Sahib and Chishti Dargah of Baba Farid Ganj Shaker in Pakpattan. The study attempts to investigate both Dargahs‘ intellectual, social and religious impact on the socio-cultural and religious set up of the Medieval Punjab.Third chapter studies the historical narration of the Dargah of Baba Farid Ganj Shaker. Investigation is done from its Khanqahi structure and its working in 11th century‘s Punjab to its Dargahi structure and its functioning in contemporary Punjab. The major purpose of the chapter is to analyze the Dargahi structure which is multifold in its character, such as its socioreligious, spiritual, political and economic function and impacts on its environs.The fourth chapter discusses manifold role of the Dargah of Khawaja Shamsud- Din Sialvi in the region. The chapter aims to analyze the significance of Chishti Sufi Dargah in late eighteenth and nineteenth centuries. It also explores the political, social, sacred and economic role of the Dargah in the region. Another distinctive feature of the Dargah which study highlights is its literary and scholastic contribution throughout the region and overall the country. In the fifth chapter the main focus is given on ritual, religious/Sufi rituals and their performance by giving emphasis on the Sufi practices at both Chishti Dargahs. Study tries to locate the reasons behind the visitation of Dargahs. To get the actual findings anthropological research is conducted and for that most of data was collected during Urs celebrations at both Dargahs. The study also takes into account the architectural structures and spaces of both Dargahs and analyzes how they have evolved through time and affected some of the Sufi practices at the Dargah.In the last chapter the research evaluates the similarities and differences in the multidimensional role of both Chishti Dargahs and also in the Sufi Practices which are performed there.
