Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

Introduction The extensive scarcity of food is known as famine, which causes a high extent of mass starvation in the region. The prevalence of famine has been observed in every continent of the world, however, some countries like Sub-Sahara Africa still encounter with the drastic effects of famine (Baro and Deubel 522). The current paper enlightens the causes and effects of famine and presents the preventive measures to reduce the prevalence of famine.

Causes

The scarcity of food is observed to be caused by the ineffective distribution of food or imbalance in the demand and supply of food. ...

Introduction

With the escalation in cost production and environmental concerns, researchers have in the recent past focused in investigating resourceful means of increasing yields while reducing fertilizer use. Arnall & Godsey assert that the seeding rate and hybrids that promise the highest crop populations is continuously sort by corn cost cultivators worldwide (2013). Nielsen et al. notes that the crop populations are tied to the end yields. Corn populations have greatly increased in Indiana over the past thirty years to make about 340 plants ...

Does the addition of fertilizer increase crop production? Farmers are very interested in the amount of fertilizer used versus how much yield a crop can give. Fertilizer costs money and determining the amount of fertilizer that will maximize production is very important. My hypothesis is that the addition of fertilizer will increase crop yield.

I predict with the addition of more fertilizer, the production of corn will increase. The dependent variable is tons of corn produced in an acre field. The independent variable is the addition of fertilizer to the field. There will be experimental plots (each with differing levels ...

Moral and ethical implications

Genetically modified organism (GMO) is an organism in which a genetic material is altered by a process called genetic engineering. It is done on micro-organisms including bacteria, yeast, fish, mammals, plants and fish. This GMO in the modern world is a source of genetically modified foods. They are widely used in research and in the production of food. Simply put, modification in the organism means inserting of genes from a different species in a process called horizontal gene transfer or deleting some genes from the organism. The process will lead to changing the organism to have different characteristic when growth from the normal ...
