Soils of Pakistan have free CaCO3, alkaline pH and low organic matter. Consequently, nutrient disorders seem among the most critical factors of crop production, particularly in salt-affected soils. The essentially of P and Zn for plants has been established long ago but interaction effects on economic yields of crops are still controversial. Wheat is the most important cereal crop in the world. In a pot study on wheat grown on salt-affected soil, results indicated that mean number of tillers per pot, height of fertile tillers, straw dry weight, 1000-grain weight and P uptake in straw was...

Pakistan is facing an acute shortage of edible oil. In order to overcome the prevailing situation, there is a dire need to increase per acre yield of non-conventional oilseed crops. Plant density and nitrogen fertilizer levels are among factors affecting sunflower yield and seed oil percentage. The interaction between plant spacing and N rate significantly affected seed and oil yields. In this context, the OILCROP-SUN model has been tested with sunflower and results indicated that achene yield of sunflower hybrid cultivar among various planting densities was related to their photosynthetic...

Ziziphus jujuba is the most commonly grown fruit in Pakistan, having essential oil that can be utilized for the purposes of preservation like jujuboside and other flavoniides. In Pakistan it is used for the treatment of ulcers, wounds, eye diseases and bronchitis. Antioxidants are naturally occurring or synthetic substances which prevent oxidation or chemical reaction involving oxygen. The main focus of this investigation was to study the chemical constituents, antioxidant activity and phytochemicals present in the Ziziphus jujuba L. The results indicated that different extracts fractions...

Meat and its products enjoy a unique status in human diet but meat also serves as an excellent substrate for the growth of most microorganisms, and is associated with hypertension and cardiovascular disease due to the presence of high sodium and fat contents. In the functional examination of minced beef patties, estimation for total sodium contents is essential to assess the level of risk. The minced beef patties were also treated with chitosan-mint mixture to minimize the presence of microorganisms, oxidation and to increase the shelf life of the product by acting as a natural antioxidant as...
