  Suitability Evaluation of Urban Soils underline by Asu River Parent Material forCassava Manihotesculenta and Bambara groundnut (Vignasubterranea (L.) Verdc) Production in Ebonyi, Southeastern Nigeria Authored by Chris-Emenyonu Nigeria is the most populous black nation in the World and in sub Saharan Africa [1]. Nigeria’s population 202,363,773 million [2], which is 61% of the World’s Population. 51.2 % of this population lives in urban area. Increase in population, especially in urban area means more persons to be fed and yet less available food in these areas due to insufficient food production as a result of unplanned land uses resulting to land degradation of urban landscape, Inadequate information on soil suitability prior to land use and lastly, Inadequate Information on urban and peri-urban soils for crop cultivation. Land suitability evaluation is used to ascertain the compatibility of the land for a specific type of use [3]. Cassava deserves special recognition as a cr...

  Effects of Calcium with and without Surfactants on Fruit Quality, Mineral Nutrient, Respiration and Ethylene Evolution of ‘Red Spur Delicious’ Apple Authored by Esmaeil Fallahi Foliar fertilization is a common practice to supply crops with mineral nutrients, especially under limited soil nutrient availability conditions [1]. However, foliar-applied nutrients must overcome the barrier properties of leaf surface to be absorbed by plants. Various pathways are reported to explain the penetration of foliar nutrients through the leaf tissues. Meanwhile, beveled that air humidity is one of the main controlling factors in this process since it controls both the actual nutrient concentration on the leaf surface [1] as the driving force of absorption and the permeability of the leaf surface. Postharvest and pre-bloom foliar nitrogen sprays are applied to enhance flower bud vigor, and calcium (Ca) is applied directly to fruit during the growing season to reduce fruit susceptibility to phys...

Remediation Methods of Crude Oil Contaminated Soil Authored by Ding Xuezhi, Crude oil is a quick and easily accessible source of energy, making our life comfortable and raising the standards of living. It can be found naturally in many parts of the world, particularly in the USA, Russia, Romania, Iran, Mexico, Iraq, Saudi Arabia, Kuwait, Libya, and Nigeria [1]. The petroleum industries generate billion tons of crude oil, natural gas and its derivatives every year. All of these are then undergone further processing for the production of refined products such as diesel, gasoline, petrol and lubricants [2]. It is recorded by international energy agency that demand of oil all over the world in 2015 was 97 million barrels/day which is expected to be 100 million barrels/day up to 2021 [3]. Crude oil is composed of volatile liquid hydrocarbons with varying molecular weight and structure. It contains more than 17,000 hydrocarbons and its classification are based on the most prevalent compou...

Nutrient Intake, Fermentation, Digestibility and Growth Performance of Barbarin Lamb Supplemented with Sweet Lupin Authored by S Abidi In Tunisia, particularly in the arid and semi-arid zones, climatic conditions have caused the degradation of rangelands leading to a chronic forage deficit and a nutritional imbalance in animals, particularly in sheep and goats. Thus, energy and / or nitrogen supplementation has become essential to maintain these animals and ensure the expected performance. For this reason, Tunisia has resorted to the import of raw materials including soybean meal, barley and corn [1]. However, fluctuations in their prices on the world market are negatively affecting animal nutrition industry. Our country imports annually, over 300,000 tons of soybean meal at a price of 1.2dt / kg [2]. Similarly, these imported raw materials are unstably available on the Tunisian market which can affect the profitability of farms and alter the sustainability of animal production sector...

Current Application of Microencapsulation Technology in Bioremediation of Polluted Groundwater Authored by Stalis Norma Ethica The long-term establishment of the global water supply and sustainability is closely related with the world population growth and global climate change. Steadfast growth of the world’s population forecasted to be almost multiplied by two from 3.4 to 6.3 billion between 2009 - 2050, is presented by a predicted required growth of 70% agriculture production by 2050 [1]. Hence, the need for fresh water is dramatically increasing, especially for food production. It is because 70% of the withdrawals of world’s freshwater are already adjudged for agricultural land irrigation. Today each year, 64 billion cubic meters of fresh water are consumed progressively by worlds’ population [2]. In developing countries, ground water contamination is a key issue, with high levels of pollutants being reported in various regions. Various contamination control and groundwater trea...
