Posterior resin composite restorations have been accepted as a valid treatment option when a controlled clinical environment is achieved. Various clinical techniques have been published suggesting methods to overcome shrinkage problems and to achieve an improved marginal seal. This study is a clinical trial to determine the presence and absence of postoperative sensitivity after placement of posterior composite restorations with two placement techniques in different depth of cavities in a dental hospital.

Cotton is an important fiber crop of Pakistan and is also the second most important oilseed crop in the world. The cotton plant possesses a narrow range of ecological adaptability and is very much influenced by the climatic conditions. Among many factors causing low yield, sowing time and plant spacing are more important. Therefore, the present study was designed to investigate the effect of different sowing times and plant distances on the growth, seed cotton yield and quality of cotton genotype BH-160 under the agro-ecological conditions of Rahim Yar Khan in irrigated environment. It may be concluded from this study that the boll number, boll weight and yield per plant decreased with closer spacing but seed cotton yield per hectare increased. The 15 cm plant to plant spacing produced more seed cotton yield due to more number to of plants per hectare, which compensated the other, yield components. Plants spacing however did not affect G.O.T%, seed index and fibre quality and plant height. Sowing date of 15th May gave maximum seed cotton yield and did not effect on monopodial branches.

Phosphorus and Zn deficiencies are common nutritional restrictions to crop production in the soils of Pakistan. The P-Zn interactions in plants have been examined in the past but their interaction effects on economic yield of crops are still confusing, particularly in sandy clay loam soils. For these reasons, a field experiment was laid out in RCBD-factorial with three replications. It is concluded from this experiment that the treatment with 40 kg P and 8 kg Zn ha-1 gave the best combination of phosphorus and zinc levels at 100 kg N ha-1. It is also the most suitable from economic point of view as it gave maximum benefit cost ratio and value cost ratio along with high net income.

Maize is an important cereal crop world wide, not only as a staple food in various parts of the world, but also as a major component of feeds for the animals. Adapted to a wide range of climates, the crop is mostly grown between latitudes 30° and 55°, principally in latitudes below 47°. It is a warm weather crop, doing best when temperatures in the warm months range from 21° to 27° C. The judicious use of organic and mineral fertilizers may increase micronutrient density in grain destined for human consumption and play a promising rule in reducing human’s micronutrient deficiency. The integrated nutrient management for crop improvement has been paid little attention in agriculture areas of developing world. Therefore, the present study was executed to evaluate the integrated nutrients use affect on growth, yield and quality of maize.

Education is the most important and dominant sector in any country. The performance of any country can be assessed by the literacy rate of that country. The countries which have highest number of educated people, are the most advanced states in the world. Pakistan was created in the name of Islam under the outstanding leadership of Quaid-i-Azam. The Quran place great emphasis on education. Pakistan is one of the least literate countries in Asia. The country population of 173.5 million have only 57.0% literacy rate, which means that more than 50 million Pakistani are not literate. Non literate population of Pakistan constitutes 6.2% of that of the world. Pakistan is the fourth largest contributor to world non literate population. Literacy is the heart and life blood of development. It also serves as engine of growth and back bone of economy.So literacy as part of basic education is seen as a key factor in a country social and economic development. The book in hand can provide valuable information for educationist, policy makers and allied sectors. Therefore, it should be in every library around the country.

Intercropping is experienced by preponderance of farmers in many regions of the world. Intercropping has since long been used as mean to cover the risk of failure of base crop and it can pilot to boost food supply without retreating the sustainability of soil. This system of cropping suppresses weeds, reduces pest disease infestation, gives yield advantage and there is stable yield over time. Crop fertilizer needs can be met with the addition of an organic fertilizer, which is suitable for enhancing crop yields on sustained basis and cost effective too. The use of legumes as an intercrop can serve a potential source of organic fertilizer. It can be used as a supplement source of nutrition especially that of nitrogen. It is an economical way of food production as one input such as N from legume can be applied once and used by all the crop components in the farm thereby saving time for the farmer. Thus present project will be helpful to farmers in order to augment the crop yield and sustain the soil fertility, identify an effective and low cost fertilizer level technique for maize and substitute N-fertilizer with leguminous crops as an organic source.
