  A field experiment was conducted at the Agronomic Research Area of PMAS Arid Agriculture University, Rawalpindi to evaluate the quality parameters of spring planted sunflower hybrids as influenced by varying potassium application doses during two consecutive years i.e. 2008 and 2009. Experiment was quadruplicated using randomized complete block design with split plot arrangement keeping different levels of nutritional area in main plots and sunflower hybrids in subplots. Protein and achene oil contents were determined by Nuclear Magnetic Resonance Technique, where as fatty acid composition was determined by GC-9A Fatty Acid Analyzer. Different levels of nutritional area significantly increased protein content and palmitic acid concentration in achene but reduced oil content when levels of nutritional area vary from 60 x 20 cm2 to 60 x 60 cm2 (2 plants/hill). However, the concentration of oleic, linoleic and linolenic remained un-affected by varying levels of nutritional area. Hybrid Hysun-33 produced significantly higher protein content (18.89%) in achene as compared to S-278. Conversely, hybrid S-278 accumulated significantly higher oil content (43.48 %) as compared to hybrid Hysun-33. No proper pattern was noticed regarding stearic, oleic, linoleic and linolenic acid accumulation in achenes. It is concluded that sunflower hybrids exhibited differential genotypic response to different levels of nutritional area by increasing oil contents, palmitic acid concentration and reducing protein contents in achenes without affecting stearic, oleic, linoleic and linolenic acid concentration.

  Agronomic traits ultimately contribute to final achene yield. Any improvement in agronomic traits means increase in achene yield. For this purpose, a field trial was conducted at experimental area of Agronomy Department, PMAS Arid Agriculture University, Rawalpindi during two consecutive years 2008 and 2009 to evaluate the performance of two sunflower hybrids i.e S-278 and Hysun-33 under different levels of nutritional area i.e, 60 x 20, 60 x 30, 60 x 40, 60 x 50, 60 x 60 (with 1 plant/hill) and 60 x 60 cm-2 (with 2 plants hill). The experiment was laid out in randomized complete block design with three replications in split plot arrangement keeping nutritional areas levels in main plot and sunflower hybrids in sub plot effects. It was observed that among sunflower hybrids, S-278 produced significantly taller plants, heavier 1000-achene weight, higher achene and stalk yield, but lesser harvest index than these in Hysun-33. Both hybrids were, however, similar for head diameter and number of achene/head. Sunflower hybrid Hysun-33 planted at nutritional area of 60 x 20 cm2 produced the highest achene yield (2.89 t/ha), which was also statistically at par with other treatments; whereas sunflower hybrid S-278 planted at nutritional area of 60 x 40 cm2 produced the lowest achene yield (2.45 t/ha). Likewise, sunflower hybrid Hysun-33 planted at nutritional area of 60 x 40 cm2 computed the highest harvest index (37.75%), which was also statistically at par with other treatments; whereas sunflower hybrid S-278 planted at nutritional area of 60 x 20 cm2 computed the lowest harvest index (31.00%). It is therefore suggested that sunflower hybrid S-278 should be cultivated at level of nutritional area of 60 x 20 cm2 to get maximum achene and stalk yield.

  Fruits and vegetables are an important part of the daily diet. Eating 3-5 servings of colorful fruits and vegetables a day is important because deeply hued fruits and vegetables provide the wide range of vitamins, minerals, fiber and phyto-chemicals which body needs to maintain good health. Eating fruits and vegetables may truly promote muscle strength and reduce the risks of neuronal aging and cancer among youth. For this purpose, a study was conducted to analyze the students’ daily intake of balanced diet. The present study was conducted on 80 female respondents in “A” university and “B” university, Faisalabad, Pakistan was selected through a simple random sampling technique. The information was gathered from respondents through a questionnaire. Later on the data were analyzed, tables of percentage was applied to interpret the results. Almost both of the students of universities knew about balanced diet. They used to take fruit and vegetable salad in the form of 1/2 cup in a day and 3-4 times in a week. Correspondingly, half of the university students either used to eat vegetable like fried potato, chat, vegetable roll, sandwich, burger or fruit juices and fruit shake at lunch time in university. Both university students agreed that inclusion of fruit and vegetable in junk food would convert the food into healthy food which can help to reduce the obesity and used in weight management programs for youth.

  Maize is a particular cereal crop which is more affected by variations in plant density than other members of the grass family, due to its low tillering ability, its monoecious floral organization and the presence of a brief flowering period. Different maize cultivars respond differently to K application under varying plant densities, due to different root/shoot ratio, growth rate, crowding stress tolerance, intra-specific competition between plants, K uptake and utilization. Maize cultivars have the ability to withstand high plant density due to more partitioning of assilimilates to shoot as compare to root, resulting in reduction of root/shoot ratio. K application reduces the percent of senescent stalks, lodging and increased crushing strength and rind thickness. There is general consensus that the soils of Pakistan have large capacity to provide K to crop under ordinary conditions, but the increase in the intensity of cropping, excessive use of the tube well water, introduction of the high yielding cultivars requiring high K, increasing use of N and P, could hasten the removal of K from the soils and imbalance the uptake of K in relation to other nutrients. Genotypic and crop species differences exist in response to soil and fertilizer K and non-yield traits such as stalk strength or product quality must be taken into account in K management decisions. K application not only increases grain yield, but also improves quality parameters. K application improves utilization of water, tolerance to drought through stomatal conductance, acceleration in photosynthesis process, water up take through roots. Its application improves leaf area, dry matter accumulation and other allometric parameters. K in combination with N has synergistic influence in uptake, translocation and utilization of nutrients for assimilation in growth and development of final grain yield and its contributing attributes. Normally K deficiency symptoms are usually not conspicuous although grain yield is abruptly decreased (called hidden hunger), but severe deficiency do express symptoms. It is therefore suggested that luxuriant application of K is inevitable for getting successful and maximum production from maize hybrids.
