A research project was initiated at the Agricultural Research Institute, Dera Ismail Khan, NWFP, Pakistan during 2002 and 2003; to provide appropriate rice cultivation technologies that are agronomically practicable and economically viable under the agro-climatic conditions of the area. The research project was based on field-oriented problems faced by the paddy growers, which was also evident from face to face interviews by 50 rice growers, actively involved in rice production from major rice growing villages of the area. field experiments relating to time of transplanting and number of seedlings hi!r'' and techniques for weed control in transplanted and direct wet-seeded rice were laid out in Randomized Complete Block Design (RCBD) with split-plots arrangements, replicated 4 times. The transplanting dates of nursery and methods of planting were maintained in main plots while the number of seedlings hill" and weed control techniques were kept as sub-plots. The sub-plot size was 2 x 5 m" The trial pertaining to impact of seeding techniques in transplanted and direct wet-seeded rice was deSigned in RCB with a plot 3 x 5 m2, replicated 4 times. Well-adapted coarse rice variety IR-6 was used in the research project. Thirty days old rice nursery was used in transplanted plots while wet pre-germinated seed was broadcast in direct seeded plots. Data were recorded on various growth and yield parameters like plant height (em), productive tillers m-'', unproductive tillers m-'', panicles m-'', spikelets panicle-" sterility and normal kernels percentage, 1000-grain weight (g), paddy yield (t ha'') and straw yield (t ha'') The data were also recorded on leaves planr'', leaf area index (LAI), net assimilation rate (NAR) at 45 and 90 days after sowing (DAS), stem borer moths'' resting behaviour at 30, 45 and 60 DAS and white heads planr'' after 90 DAS in all experiments of the project. The sample size in experiment 1 was determined by using simple random sampling procedure of probability sampling. A sampling frame was developed that carried details of farmers involved in rice production. This was identified by collecting information from the key informants. The findings of the survey elucidated that water shortage, high cost of inputs, non-availability of skilled labour during peak planting season, sub-optimal plant population, weeds and pest infestation, high dependence xiv of knowledge on nearby growers and low price of nce in Ihe locel markel were the major restrictions in higher yields of rice, In experiment 2, the effects of transplanting dates and number of seedlings hilr'' were found 10 be significant in most of the agronomic and physiological parameters studied The highest paddy yield during 2002 and 2003 (5 and 8,1 t ha") respectively, higher net return of Rs, 7,830 and 23,330 /la"and Benefil Cost Ralio (BCR) of 0.44 and 1,32 were recorded on 20''h June planted crop with 1 seedling hiW'' during both the expenmental years, Similarly in experiment 3, the effect of planting tec/1niques (transplanting VS, direct seeding) and weed control practices including granular herbicide Sunstar 15WG (Ethoxy sutfuron), conventional hand weeding and herbicide Machete 60EC (Butachlor) Significantly influenced the yield and yield centributing attributes during either year of the study Both the Sunstar and Machete application proved their efficacy against the weeds but could not match with hand weeding treatment Minimum weed population m'', dry weed biomass g m" after 30, 60 and 90 DAS and maximum paddy Yletd (5.7 and 8.5 t he") during both the experimental years and its assOCiated components were receded in transplanting method as compared to direct seeding. Similarly, among weed control strategies, the paddy yield, net return of Rs,13, 815 and 27,815 ha''and BCR were the highest in hand weeding, followed by herbiCide application of Machete 60EC, The direct seedmg method could not perform in a good way in terms of low paddy yield and high weed infestation. While in experiment 4, the effect of seeding techniques was significant for most of the agronomic and physiological parameters However, transplanting Hat and parachu1e planting techniques showed the outstanding performance for most of the characters investigated. Maximum net relum of Rs. 12,630 and 15,730 and 6,050 and 14,800 was recorded In transplanting on flat and parachute planting techniques, respectively dunng both the planting seasons Other seeding techniques such as diract seeding on flat, direct seeding on ridges and transplanting on ndges could not excel transplanting on flat and parachute planting in most of the ahributes recorded. On the basis of research findings, it is concluded that conventional transplanting technique on flat with a plant-ta-plant and row-ta-row spaCing of 20 em is most suitable on planting date 20" June with 1 seedling hill". Among weed control practices, hand weeding is most effective, followed by herbicide treatment Machete 60EC Nursery preparation and seedling broadcasting of parachute technology although, a cumbersome job but produced higher paddy yield and nel return per unit area.
صبح کی سیر اللہ تعالیٰ نے دنیا کی ہر نعمت سے مستفید ہونے کے لیے بنی نوع انسان کو وافر مقدار میں مواقع فراہم فرمائے اور اسے یہ باور کرانے کی ترغیب دی کہ وہ زمین پر نکلے اور مظاہر فطرت کا بغور مشاہدہ کرے، دیکھے کہ شجر دحجر، بحرو بر ،کو ہ و دامن کا وجود کس طرح اللہ تعالیٰ کی موجودگی کا واضح ثبوت پیش کر رہا ہے۔ صبح کی سیر اگر چہ ظاہراً تو جسمانی صحت کو بحال رکھنے کے لیے ناگزیر ہے لیکن حقیقتاًیہ مظاہر فطرت سے بالمشافہ گفت و شنید کا نام ہے یہ جسمانی صحت کے ساتھ ساتھ روحانی طور پربھی انسان کو پاکیزہ اور فعال بناتی ہے۔ صبح کی سیر سے انسان کا دل اور دماغ تروتازہ ہو جاتا ہے، کام کرنے کی صلاحیت بڑھ جاتی ہے، طبیعت میں تساہل اور غفلت کی انگڑائیاں لیتے ہوئے جذبات کا فور ہونا شروع ہو جاتے ہیں۔ دماغی صلاحیت میں اضافہ ہونا شروع ہو جاتا ہے۔ یہ نسیمِ صبح جب اٹھکیلیاں کرتی ہوئی قریب سے گزرتی ہے تو فہم و ادراک کے آنگن میں بہار آ جاتی ہے، نظریات و تصورات کا تفاوت ختم ہونا شروع ہو جاتا ہے۔ گراں خوابی کے دور سے پیدا ہونے والے زخم آفتاب کی مسیحائی کرنوں سے مُندمل ہونا شروع ہو جاتے ہیں۔ دلیل صبح روشن ہے ستاروں کی تنک تابی افق سے آفتاب اُبھرا گیا دورِ گراں خوابی صبح کا وقت سہانا ہوتا ہے، شب کے بحرِ ظلمات میں ہچکولے کھاتی ہوئی نائو اُجالے کے ناخدائوں کے طفیل سنبھلنا شروع ہو جاتی ہے۔ صبح کا منظر پہاڑوں کی فلک بوس چوٹیوں پر ہو، دریاؤں اور سمندروں کی خونی موجوں اور لہروں پر ہو، چٹیل میدانوں پر ہو، کھیتوں اور کھلیانوں پر ہو، ہمیشہ بھلاہی نظر آتا ہے۔صبح کی سیر چھوٹے قد کا شخص کرے، یا...
Vaccines stability has a major role in the success of immunization programs and saves millions of lives every year. To stabilize vaccines cold chains are developed for storage and transport, as efficiency of vaccines is hampered if they are not kept under proper temperature. Aluminum is used for making vaccine thermostable. The development of vaccine formulation is a critical part of overall development cycle of approving, testing and producing new vaccines. However, Liquid vaccine formulation is still preferred over dry formulation because of ease in using, packaging and manufacturing. Other approaches have been used to make vaccine thermostable. This study demonstrates those processes, used to develop thermo-sensitive vaccines into thermostable vaccine and also describes vaccine formulation designing and use of heat shock protein including mHSP70 and mHSP65 to generate innate and adaptive immune response.
River Sutlej is the most polluted river at this point in South Asia. Noticeable quantity of metals is thrown into this water body. Among them, the notable pollutants are heavy metals. These heavy metals are accumulating in the different organs of fish and have adverse effects. The present work was attempted for assessing some heavy metals pollution in River Sutlej that also accumulates in the different organs of edible fishes captured at Islam Barrage. Sediments, water and fish samples were collected in both winter and summer seasons. The concentration of heavy metals including the Chromium, lead and iron, copper, nickel and cadmium were estimated through atomic absorption studies in all the water, sediments and organs of Cirrhinus mrigala, Oreochromis mossambicus and Sperata sarwari. Physico-chemical parameters of water were tested to check level of nitrates, dissolved gases and PH. Haemotological analysis and micronucleus tests were conducted for sampled fish. Data was analyzed statistically and represented as Mean? SD and compared through ANOVA using MSTAT computer packages. The results of physiochemical parameters revealed that the levels of all the parameters under observation in the summer season were found elevated but two factors dissolved oxygen and PH were found less in summer season than the winter season. Presence of heavy metals in sediments sampled in both summer and winter seasons showed that the concentrations of different metals in the winter seasons were slightly higher as compared to the summer season because in winter the link canals add less water in river and more pollutants are poured by different industries into the river. It was concluded that these heavy metals in the form of waste is added into this river from different factories present near kasur city of Pakistan.
