جو دیپ پلکوں پہ دھر رہا تھا
وہ شب کا کشکول بھر رہا تھا
چہار سو نور تھا زمیں پر
کوئی فلک سے اتر رہا تھا
اُدھر بھی تو ایک زندگی ہے
وہ جی رہا ہے جو مر رہا تھا
ہوائے شب اشتعال میں تھی
چراغ جلنے سے ڈر رہا تھا
ہماری آنکھوں میں تشنگی تھی
کہ دل کا دریا اتر رہا تھا
سمیٹتا کیا وہ مجھ کو آ کر
جو خود ہی ہر پل بکھر رہا تھا
جو آ رہے ہیں شفیق آصف
میں یاد ان کو ہی کر تھا
From the very beginning Islam has given great importance to discipline. In every facet of life discipline has a role to play. Today when we delve deep in to our lives, we are amazed as to how it has always proved its worth. It has brought the tide of revolution in everyone's mind. Similarly, the element of discipline saves a society from disruption and instability. It infuses in life satisfaction and contentment. Contrarily, indiscipline and mismanagement give birth to dejection and dissatisfaction. Time management plays a vital role in the establishment of discipline in a society. Considering the vast importance of time management in the light of discipline, the following article throws a great deal of light on it in the Islamic perspective.
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.
