Investigation on Intercropping of Ziziphus Mauritiana With Cajanus Cajan for Fruit and Fodder at Marginal Land and Cultivation of Carissa Carandas for Fruits Through Saline Water Irrigation
Salinity is a growing threat to crop production which affects sustainability of agriculture in arid/semiarid areas. Growth responses of plant to salinity vary considerably among species. Cajanus cajan, Ziziphus mauritiana and Carissa carandas are sub-tropical crops, grown worldwide particularly in Asian subcontinent for edible and fodder purposes but not much is known about their salinity tolerance and intercropping. Effect of salinity has been initially studied in present work at germination of C. cajan under different sea salt salinities using presoaked seeds with water and respective salt solutions. Seed germination decreased with increasing salinity and it was more sever in presoaking under water of different salinities. The 50% threshold reduction started at ECiw= 3.5 dSm-1 sea salt in presoaking treatments. However, this threshold was decreased up to ECiw= 16.8 dSm-1 sea salt at further seedling establishment stage. Growth experiment of C. cajan in drum pot culture (Lysimeter) also showed a salt induced growth reduction in which plant tolerate salinity up to 4.2 dSm-1. At this salinity, leaf pigments (chlorophylls and carotenoids), proteins and insoluble sugars decreased up to 50% whereas, soluble sugars were increased (~25%). Reproductive growth was also affected at this salinity, in which at least 70% reduction in flowers, pods and seeds were observed. Salt tolerance of symbiotic nitrogen fixing bacteria associated with root of C. cajan showed salinity tolerance up to ECw= 36.6 dSm-1 NaCl salinity invitro environment. For intercropping experiments, Ziziphus mauritiana (grafted variety) was selected with C. cajan. Preliminary investigations showed a growth promotion in Z. mauritiana at low salinity (ECe= 7.2 dSm-1) and growth was remained unaffected up to ECe= 11.1 dSm-1. Intercropping of C. cajan with Z. mauritiana was primarily done in drum pot (Lysimeter) culture. Result showed better growth responses of both species when growing together as intercrops than sole in which encouraging results were found in 8th day irrigation interval rather than of 4th day. Biochemical parameters e.g. photosynthetic pigments, protein, phenols, electrolyte leakage and sugars of these species displayed increase or decrease according to their growth responses. Increased activity of antioxidant enzymes and that of nitrate reductase and its substrate (NO3) also contributed in enhancement of growth. Field experiment of intercropping of above mentioned plants at marginal land irrigated with underground water (Eciw= 2.8 dSm-1) showed better vegetative growth of both species than sole crop. The overall reproductive growth remained unaffected, although, the numbers, size and weight of fruit were better in intercropping system. Photosynthetic pigments were mostly increased, whereas, leaf protein and sugars remained unchanged. In addition, higher values of LER and LEC (> 1) indicated the success of intercropping system. Experiment on salinity tolerance of Carissa carandas (varn. karonda) using drum pots culture showed improvement at low salinity (up to ECiw= 4.2 dSm-1 sea salt) whereas, higher salinity (ECiw= 12.9 dSm-1 sea salt) adversely affected vegetative and reproductive growth. Plant managed to tolerate up to ECiw= 9.9 dSm-1 sea salt. Salinity severely affected biochemical parameters including photosynthetic pigments, proteins and sugars, whereas leaf phenolics were increased. Leaf accumulated high amount of Na+ whereas, affect absorption of essential minerals like K+ was decreased. In the light of above mentioned investigations, it appears that, C. cajan can be propagated in saline soils with good presoaking techniques in non-saline water which would helped to grow at moderately saline conditions. It could be a good option used as intercrop species because of its ability to improve soil fertility even under water deficit conditions. The proposed Cajanus-Ziziphus intercropping system could help poor farmers to generate income from unproductive soils by obtaining sufficient fodder from C. cajan for their cattle and producing delicious edible fruits from Z. mauritiana for commercial purposes. Carissa carandas could also be introduced as new crop for producing fruits from moderate saline waste lands and used for preparing prickle, jam, and jelly for industrial purposes.
بجھ گیا ہے دل سے شعلہ عظمتِ پرواز کا بے پروں کے جھنڈ دیکھے ہیں زمیں پر رینگتے صورتِ شاہیں کرے تسخیر جو دلکش فضا وہ پرندہ شوق سے اڑتا پھرے شام و سحر عمر بھر اس نے تھکن سے واسطہ رکھا نہیں آسماں کی سمت اڑنے میں مری توقیر ہے جو قفس میں زندہ رہنے کے لئے تیار ہیں ہمتِ پرواز میرے خوں میں ہے محوِ سفر سربلندی کی طرف صابر اسے مائل کرو
پڑ گیا ہے ماند جذبہ عظمتِ پرواز کا سن رہے ہیں صرف قصہ عظمتِ پرواز کا اس کے سر پر باندھ سہرا عظمتِ پرواز کا پی لیا ہے جس نے دریا عظمتِ پرواز کا چکھ لیا تھا جس نے خوشہ عظمتِ پرواز کا مل گیا ہے مجھ کو زینہ عظمتِ پرواز کا پڑھ رہے ہیں مل کے نوحہ عظمتِ پرواز کا سوچ میں باقی ہے نقشہ عظمتِ پرواز کا پوچھتا ہے جو بھی رتبہ عظمتِ پرواز کا
The doctrine of Khul’ has, within the course of last few years, assumed a great deal of importance in Pakistan because literacy rate in women is increasing rapidly and their dependency on men is decreasing. Now, women can easily make their own decisions with free consent due to their some awareness about their rights, especially regarding dissolution of marriage. Majority of women is still ignorant about dissolution of marriage on the ground of Khul’. Therefore, it is very necessary to explain all different aspects of “doctrine of Khul’” for ensuring justice in our society. The present research has mainly explored the grounds of judicial Khul’ and other relevant incidents in the light of Pakistani Case Law based on Islamic family Law. The research is based primarily on the decisions of superior courts of Pakistan. The decisions of family courts of Pakistan have been included in the discussion. The relevant provisions of the Dissolution of Muslim Marriages Act, 1939 and the Family Courts Act, 1964 have also been debated. The difference between Khul’ and other modes of dissolution of marriage have also been elaborated briefly.
The purpose of this research was to understand organizational change initiative in public sector organization. To expound the understanding, planning and initiation of public sector organizational change, a comprehensive and integrated study was required. It was also essential to undertake employee’s perspective and their descriptive experiences about the change process and the magnitude of employment of New Public Management (NPM) practices. Computerized Driving Licensing Authority (CDLA) of Khyber Pakhtunkhwa Traffic Police (KPTP) was selected for investigation. An exploratory study was framed in compliance to nature of the current study based on employees’ experiences, therefore, this research adopted social constructionist’s perspective with the help of narratives. Semi-structured in-depth interviews were designed and conducted on the employees of an organization at the time of change initiation. In total thirty-one interviews were conducted, including one repeat interview with project team member. Interviews were transcribed and grouped into meaningful information using narratives and thematic analysis techniques. A technology driven change was detected in CDLA with a focus on process-oriented change. The employees’ resistance and negative response towards change was ascribed to the lack of HR planning and practices. It was also found that there were several causes (including system related issues and human-related issues), components, complexities and constraints to the implementation of organizational change in CDLA. The change was brought in several phases using a stepwise approach. Moreover, gaps were identified in two successional phases of planning and implementation of change process. It was evident from the inquiry that technocrats were not welcomed in the bureaucratic system which led to hurdles at the launching phase of reform initiative for project team. In CDLA, few characteristics of NPM were objectively prevailing in vii practice, however, the study stipulated the absence of complete use and essence of NPM by public sector of KP. This research provided a comprehensive direction for future research including multiple case studies investigation, development of change model for developing countries and further exploration of change in autocratic organizations.
