» Abstract Incredible accomplishments have been achieved in agricultural production in China, but many demanding challenges for ensuring food security and environmental sustainability remain. Field experiments were conducted from 2011–2013 at three different sites, including Honghu, Shayang, and …Continue Reading »
» ABSTRACT Two field experiments were carried out to evaluate the effects of Moringa leaf extract on the growth, yield and yield components of snap bean. The results showed that Moringa leaf extract applied at 11, 20, 33 and 50% concentration to snap bean plants at 10 days after emergence significa…Continue Reading »
» CHAPTER ONE INTRODUCTION Cassava is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous roots, a major source of carbohydrates. It is a shrub with an average height of one meter, and has a palmate leaf formation. Cassava belongs to the fami…Continue Reading »
» ABSTRACT The effect of crude oil contaminated soil on physical and biochemical properties of beans (phaseolus vulgaris) was investigated. Fifteen polythene pots with drainage holes at the bottom, each containing 10 kg of surface soil, were randomly placed on a table in the screenhouse in a fac…Continue Reading »
» CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY Soil testing is a set of various chemical processes that determine the amount of available plant nutrients in the soil, but also the chemical, physical and biological soil properties important for plant nutrition, or “soil health”. Chemical…Continue Reading »
» CHAPTER ONE 1.0. INTRODUCTION Fertilizers are materials of natural or synthetic origin which when applied to soils or to growing plants can promote their growth and yield. They supply one and more nutrients essential to the growth of plants. John L. Halvin et al (2014) in his book “Soil Fertil…Continue Reading »
» CHAPTER ONE INTRODUCTION Pollution of agricultural soils is one of the most prevalent problems associated with the exploration and processing of petroleum hydrocarbon (Ayotamuno et al., 2006). Crude oil often known as “black gold” is a major source of income and support for Nigeria ec…Continue Reading »
» CHAPTER ONE 1.0 INTRODUCTION As human populations have grown and living standards have raised, the requirement for agricultural products have increased enormously. More land have been brought under cultivation, including marginal lands that are particularly vulnerable to degradation (Johnson and…Continue Reading »
» CHAPTER ONE 1.1 INTRODUCTION The need to take account of spatial variability of soil properties when modeling soil forming and environmental processes is now clear and known. Understanding the distribution of soil properties in the field and its variability are important in refining agricu…Continue Reading »
» ABSTRACTThis project was carried out at government reservation area (GRA) Benin city Edo state Nigeria. It was a field experiments with four treatments replicated four times. This was carried out in plot of land measuring 3.1m by 4.1m. 1kg of poultry manure was added in treatment 2 and 3. 15.78g of …Continue Reading »
» ABSTRACTThe current 305 Field Practical Training Farm site of the Faculty of Agriculture, University of Benin (Ugbowo), Benin City, Edo state in Nigeria was selected for the study. It has been used for cropping (sole and intercropping) over 12 years were analyzed chemically for the evaluation of bas…Continue Reading »
» ABSTRACTMicronutrients are essential for good crop performance. There is little or no quantitative data on the content and distribution of micronutrients in soils of Edo State, particularly those derived from coastal plain sand parent material. A study was therefore undertaken to: (1) characterize t…Continue Reading »
