عداوتوں کو تیرگی ، وفا کو روشنی کہا
تمام عمر ہم نے تو جو سچ تھا بس وہی کہا
کوئی غلط نہیں یہاں ہے اپنا اپنا نظریہ
کوئی کہے ہوس ہے عشق میں نے تشنگی کہا
یہ روز و شب کے حادثوں میں ہر گھڑی کی موت کو
مجھے دکھاؤ شخص وہ کہ جس نے زندگی کہا
چھڑا کبھی جو تذکرہ تمھارے حسن کا تو پھر
بہارِ جاں کسی نے تو، کسی نے ساحری کہا
کسی نے پوچھا جب کبھی جو فلسفہ حیات کا
سمیٹ کر شعورِ عشق ہم نے شاعری کہا
Ḥajj―an annual Islamic congregation―is a supreme manifestation of Faith (Imān) in which muslims assemble to pronounce explicitly their subservience and loyalty to Almighty Allah alone. Besides freeing themselves from the squalor of Shirk, Muslims satiate their souls with the feelings of ‘Faith’ and ‘Unity.’ This fact is purely accomplished when the Muslims shed off their outer difference by donning the dress of unity (Iḥrām). Ḥajj is a perfect blend between ‘Creator’ and ‘creature’, ‘soul’ and ‘spirit’ on the one hand and an enduring and invaluable expression physically, socially, and materially on the other. From this pragmatic Institution, Pakistan―one of the premier countries of the Islamic world―can derive unprecedented benefits politically, socially, and economically. One of the important objectives of the paper is to describe the significance of Ḥajj to the people of Pakistan. In so doing, the paper examines and explores, objectively and analytically, the institution of Ḥajj and its implications on the Muslim world, particularly Pakistan. The first section of the paper, “Ḥajj―At a Glance”, presents meaning and historical background of Ḥajj. The second section “Revitalizing the Ḥajj”, besides presenting the revitalization of the Institution by the final Messenger (peace be upon him) also gives an overview of some of the very important rituals to be realized (during Ḥajj). The subsequent sections, “Socio-Economic Dimension of Ḥajj” and “Ḥajj―Implications and Impact on the Society of Pakistan”, describe respectively the socio-economic impact and leverage of the Ḥajj on the Muslim world in general and on Pakistan in particular. The study is followed by “Conclusion” wherein it has been argued that the Ḥajj can bring an immense transformation and positivity in a country if its sweetness is sought in all earnestness.
Calcium carbide (CaC2) has occupied an important position among different sources of ethylene (C2H4) for improving growth and yield of vegetables. Calcium carbide dependent C2H4 can cause noteworthy improvements in growth, yield and fruit quality of vegetables but its effect on physiological and morphological parameters of vegetables is completely concentration dependent. Under critical environmental conditions, an abrupt release of C2H4 from CaC2 can impede growth and yield of a crop as it initiates leaf, flower and fruit senescence and finally great loss of yields. However, CaC2 dependent released C2H4 can be more constructive and worthwhile for non-conventional production of vegetables if it is applied along with salicylic acid (SA). Salicylic acid not only impedes C2H4 biosynthesis but also plays a crucial role in plant physiology as a stress hormone. As comparative effects of C2H4 released from CaC2 and SA are not thoroughly investigated particularly for production of vegetables with improved quality, therefore, a series of laboratory, pot and field studies were conducted to scrutinize the effectiveness of CaC2 dependent C2H4 with and without application of SA for seed germination, physiological, morphological, yield and quality parameters of sweet pepper. Experiments were conducted in three sections. Section I, II and III consisted of four laboratory, three wire-house/pot and two field experiments, respectively. From first experiment of section-I, polyethylene and paint were selected as the most effective materials for coating CaC2. In second experiment of section-I, it was observed that CaC2 up to 14 mg plate-1 induced early seed germination with 100% germination rate and better seedling growth parameters but application of CaC2 ˃16 mg plate-1 inhibited seed germination and seedling growth parameters of sweet pepper. Similarly, results of third experiment of section-I revealed that SA concentration ≤0.4 mM can be used to improve germination percentage and seedling vigor of sweet pepper. In last experiment of section-I, it was noted that SA alleviated injurious effects of CaC2 with ˃16 mg plate-1 on seed germination and seedling growth parameters. In section-II, data revealed that 20 mg CaC2 kg-1 soil while 0.3 mM SA can be used for maximization of sweet pepper productivity. In last pot trial, effect of CaC2 with and without SA was investigated on growth, yield and fruit quality of sweet pepper under salinity stress. It was observed that detrimental effects of excessive C2H4 from CaC2 on physiology, photosynthesis, growth and yield of sweet pepper were mitigated by the foliar application of SA under saline conditions. On the basis of preliminary trials of section I and II, two field experiments were conducted on two different locations (section-III). Results of both field experiments showed that application of CaC2 along with foliar application of SA improved photosynthetic activity by 7-77%, plant water use and carboxylation efficiency by 10-211%, antioxidant and enzyme activities by 15-53% and finally fruit yield by 5-34% with a significant increase in fertilizer use efficiency compared to that of plants without SA and CaC2 application (control). Additionally, quality parameters related to chemical composition of sweet pepper fruits were also improved by the application of CaC2 with foliar application of SA. These parameters are very much required for improvement in shelf life. In short, results confirm the synergistic role of SA and CaC2 for improving physiology, growth, yield and quality of sweet pepper. Our results suggest that application of 200 mg plant-1 polyethylene coated CaC2 with foliar application 0.1 or 0.3 mM SA is relatively more economically beneficial and effective than application of 200 mg plant-1 polyethylene coated CaC2 without foliar application of SA. Moreover, results also indicated that SA treated plants were tolerated abrupt release of C2H4 from applied CaC2 to a greater extent.
