Sugarcane (Saccharam officinarum.L) is main stay for sugar industry in Pakistan. However, our average yield is for less than that of world average owing to the following reasons namely inappropriate use of cultivars, imbalance use of fertilizers and improper use of planting methods. In order to investigate and finding out a viable solution to the agronomic and management issues, a study consisting of two experiments was carried out.Randomized complete block design with Split plot design were used for conducting these experiments. First experiment was aimed at evaluating the ratooning, high stripped and sugar yield potential of three cultivars HSF-240, CPF-246 and L-178 under four different planting methods such as Pits with 90 cm spacing, Diagonal pits with 90 cm spacing, 90 cm spaced double row stripsand 120 cmspaced trench planting. Second experiment was focused to investigate role potash nutrition for cane crop under different planting methods. Four potash nutrition levels like 0, 100, 200 and 300 kg/ha were in sub plot whereas four planting methods (same as first experiment) were in main plot. After analysis of variance, it was inferred that 100 kg/ha potash nutrition is best treatment with planting method 90 cm spaced pits of diameter 90 cm in diagonal arrangement because of better stripped cane yield, high sugar recovery was possible by the combination of above mentioned treatment .Nutrient efficiency of 76.54 kg/kg and 53 kg/kg during both plant crop and ratoon crop year was also attainable with the supplementation of each additional kg of potash. Spaced trenches of 120 cm were also economically profitable; however, their economic yield is comparable with 90 cm spaced pits of diameter 90 cm. Potash nutrition is also important source for stripped cane yield improvement in ratoon crop but economically has less benefits as compared to benefit cost ration (BCR) of control and other treatments.However, sugar recovery was enhanced by the application of potash nutrition during both plant and ratoon crop years. The CPF-246 was found to be a highly potential cultivar which gave better yield of 95 t/ha and a good sugar recovery of 12.4%. The CPF-246 was also the best ratooning cultivar because it increased sugar recovery and sugar yield because of unique genetic makeup and adoptability to the Pakistani climate. It can be concluded that if sugarcane crop would be sown in 120 spaced trenches with the supplementation of 100 kg/ha K2O, it would be economically proficient with adequate sugar recovery. Moreover CPF-246 is the best cultivar amongst three for better sugar recovery and productivity.

عمر سعید

ایڈیٹر برہان کو صدمہ
قارئین برہان کو یہ معلوم کرکے افسوس ہوگاکہ ۱۰؍جولائی کومولانا سعیداحمد اکبرآبادی مدیر برہان کاجواں سال بیٹا ’’عمر سعید‘‘ عمر۴۰ سال مختصر علالت کے بعد انتقال کرگیا۔ اِنَّالِلّٰہِ وَاِنَّااِلَیْہِ راجعون۔
مولانا کو مفتی صاحب ؒ کی وفات کاصدمۂ جانکاہ ابھی تازہ ہی تھا کہ ناگاہ ایک یہ حادثہ بھی پیش آگیا۔مولانا کواس قدرسخت صدمہ ہے کہ انھوں نے لکھنا پڑھنا سب ترک کردیا ہے اور ان پرایک عالم گمشدگی طاری ہے۔ قارئین سے درخواست ہے کہ وہ مرحوم کے لیے دعائے مغفرت کریں اورمولانا کے لیے بھی دعا فرمائیں کہ اﷲ تعالیٰ انھیں صبر جمیل کی توفیق عطا فرمائے ۔

Correlation between Onset of Renal Disease with Diabetes onset of renal disease in diabetics

Diabetes is associated with number of vascular and nonvascular complications, and the vascular complications which include Cardiovascular Disease (CVD), peripheral vascular disease (PVD), stroke, retinopathy, neuropathy, and Diabetic Kidney Diseases (DKD are responsible for most of the morbidity and mortality attributable to diabetes. Objective: The aim of this study was to determine the correlation of onset of any renal disease with diabetes in Pakistani population. Methods: A cross sectional study was conducted at Medicine and Nephrology Departments of the Sir Ganga Ram Hospital, Lahore, over a period of 3 months, after obtaining the ethical approval from the The University of Lahore. A total number of 100 Diabetic patients were selected through non probability convenient sampling technique. Patients of both sexes and all age groups were included. Results: In this study 60% were male and 40% were female. Most of the patients belonged to lower socioeconomic status. Frequency of onset of diabetes with age showed that patients between age of 41-50 years (33%) were more susceptible to diabetes and its complications whereas onset of diabetes was relatively higher in males as compared to females. Frequency distribution of CVD among diabetic patients was 19%. Conclusions: Results of current findings showed that diabetes mellitus also leads toward further microvascular complications and co-exist with different diseases. 

Implications of the Adoption of Water Saving Irrigation Interventions for Enhancing Wheat Yield at Small Farms of District Faisalabad Pakistan

Pakistan is an agricultural country. Agriculture is the mainstay of the country’s economy. Wheat as a staple food crop of Pakistan is grown on about 8 million hectares every year. It is a Rabi (winter) crop and follows by rice and cotton in rice-wheat and cotton-wheat systems, respectively. Pakistan’s population is increasing at an alarming pace and it has reached to about 170 million already. It is, therefore, imperative to enhance wheat yield by encouraging farmers, predominantly small farmers, to grow more wheat with efficient and judicious use of land and water resources. Land and water resources especially for agricultural purposes are getting scarce day by day due to mismanagement. This water deficient scenario is also posing serious threats to food security for coming generations. A shift in the irrigation techniques intervening flooded irrigation methods for efficient utilization of resources are being recommended and same has been actively adopted in many areas of the Pakistan. The irrigation water saving technologies mainly include Watercourse Improvement, Improved farm layout, Laser land leveling and bed planting of wheat. The techniques adopted in the Punjab have shown encouraging results. To see the adoption of latest technologies at small farms, district Faisalabad was selected as study area, which consists of five Tehsils; Faisalabad, Jaranwala, Sammandri, Chak Jhumra and Tandlianwala. To see implications of the water saving irrigation interventions a tehsile wise list of improved watercourses was collected from the office of the District Officer, Water Management Faisalabad. A list of 25 watercourses was separately prepared duly authenticated by water management officer, where maximum water saving interventions were applied. Ten improved watercourses where maximum (5 or 6 out of 10 water saving irrigation interventions)were found applied, were selected by using Randomizer.com pathway from each Tehsil, thus total 30 improved watercourses were taken where maximum water saving irrigation interventions were applied. From these 30 watercourses 9 small farmers (having landholding<12.5 acres) were selected randomly from each watercouse, 3 from Head, Middle and Tail, respectively. Quantitative data were analysed using the Statistical Package for the Social Sciences. Descriptive statistics, including frequencies, percentages, means, standard deviations and rank orders were used to summarize different variables. Chi-square, Contingency Coefficient test was also used to find out the association and degree of association between dependent and independent variables. The adoption level of farmers regarding water saving irrigation was 90%and increase in wheat yield was significantly affected. Overall the results of the data show that adoption of the water saving interventions affected the income of the respondents. Furthermore the adoption of water saving interventions as well as wheat sowing recommendations also affected upon the socio economic conditions of the respondents. There also existed significant association among different independent and dependent attributes.
