Faba bean (Vicia faba L.) is considered the main leguminous crop grown in Egypt. It is grown for dry seed and fresh consumption. It is an important legume crop due to its high nutritive value in both energy and protein contents. At the same time faba bean offers ecosystem services such as renewable inputs of nitrogen into crops and soil via biological ambient N2 fixation (Jensen et al., 2010). Production of faba bean in Egypt is still limited and fails to face the drastic increasing of local consumption, this is related to the cultivated area of faba bean in Egypt is relatively small and decreased dramatically in the last decade. According to the Ministry of Agriculture Statistics, faba bean showed decrease in both area and production. In 2007, …show more content…
The primary benefit of the tea will be a supply of soluble nutrients, which can be used as a liquid fertilizer. Also, the suppressive activity of different compost types toward several plant pathogens is well documented in the recent review of Litterick et al. (2004). Edwards et al. (2006) reported that transition from synthetic fertilization to compost tea may be feasible because much of the environmental pollution was happened in recent years. Also, tea produced from compost manure suppressed plant disease. Enteshari et al. (2012) mentioned that excessive use of fertilizers disturb the ecological balance and biological environment and also has caused many environmental hazards. However, using of organic compost reduces the negative effects of chemical fertilizer and improves water retention and enhances soil …show more content…
These are natural organic polyelectrolytes present in the soil humus and stabilized soil organic matter. These molecules have ecological importance, as they intervene in the regulation of a large number of chemical and biological processes that occur in the natural ecosystems (Chen et al., 2004). Humic and fulvic acids are the main parts of humic substances and have a high value for soil fertility and plant growth in agricultural crops. It comprises 65-70 % of the organic matter in soils. There is a world-wide acceptance that humic and fulvic acids are a vital part of their fertilizer program. It can be applied directly to the plant foliage in liquid form or to the soil in the form of granules or solution (Osman et al., 2013). Fulvic acid is soluble in strong acid solutions (pH = 1). An oxygen-to-carbon ratio greater than 0.5-1 indicates more acidic character than in other organic fractions of humic acid. Its structure is best characterized as a loose assembly of aromatic organic polymers with many carboxyl groups (COOH) that release hydrogen ions, resulting in species that have electric charges at various sites on the ion. The major functional groups of humic acids include carboxyles, phenolic hydroxyls, alcoholic hydroxyls, ketones, and quinones (Russo and Berlyn, 1990).
Hypothesis: If one-day pinto bean seedlings are soaked in a water solution, 1% NaCl solution, and 3% NaCl solution, the seedlings exposed to higher sodium concentrations will have decreased cellular respiration rates. Treatments: This experiment involved three treatments and a control. The goal of the experiment was to see how different levels of NaCl affect the rates of cellular respiration in day-old pinto bean seedlings.
Another example of how immigrants are mistreated is usually when they come to America. Although America is usually advertised as a “safe heaven” or “land of opportunity”, it could also be a very cruel and difficult place for foreigners to try and fit in. There was a part in the infamous book Of Mice and Men written by John Steinbeck where Crooks was not allowed to play cards or even sit at the same table as the other men because he was black (not originally from America). This example depicts how poorly immigrants can be treated in a so-called “land of opportunity”. The novel The Bean Trees written by Barbara Kingsolver contains yet another great example.
How The Bean Trees is a coming of age themed novel In The Bean Trees Taylor and Lou Ann struggle to come of age, or mature, with these two being very important characters I believe a major theme of the book is coming of age. There are many pieces of evidence to support this claim, therefore I will provide them. Our first example would have to be Taylor’s journey throughout the book.
The Bean Trees, by Barbara Kingsolver and My Sister’s Keeper, by Jodi Picoult are both books that show a moral dilemma. Anna forces a moral dilemma when she chooses to sue for the rights to her body. Taylor is constantly facing dilemmas in her life, such as whether or not the keep Turtle or to help Estevan and Esperanza. These books have many similarities as well as differences in aspects including theme, characters, plot, and genre. The theme in The Bean Trees is that family does not have to be blood related.
In the igbo culture, kola nuts have highly been used for multiple reasons, such as marriages, festivals, and rituals. Sign of the kola nuts in igbo culture have been very idolized by the people and respected an honorable item to have during an event. In marriages kola nuts are very respected and are a sign for showing growth and prosperity in the relationship of the wife and husband, in festivals the kola nuts shows the happiness and love for one another. In many ceremonies it is tradition that the eldest man breaks the kola nut, the presentation of a kola nut to a visitor is a cordial welcome.
Poetry is a unique form of literature that allows authors to convey important messages in a concise way. Since poets have such a short window to demonstrate a lesson to their audience, it is crucial that they are particular and strategic with each word and piece of punctuation used. All of these small pieces work harmoniously to create a full picture of the poem itself, and the author’s meaning behind it. Lisa Parker’s narrative poem, Snapping Beans, is the epitome of how poetic elements provide the reader with a story and lesson to reflect on in the future. It depicts a young girl who returns to visit her southern and traditional Grandmother after recently attending college.
The roots of the plant leave behind better quality soil, which in return reduces the need for unnatural fertilizers, thereby drastically reducing chemical runoff. “50% of all pesticides used in the country are associated
I believe that in Egypt a complex society emerged because of the location they chose to inhabit. The Egyptians had a more productive and protected area of land. The Nile River was predictable and made it easier to grow crops (Wallech, 2013, p. 54). In addition, the Egyptians had only one of four frontiers susceptible to invasion (p. 54).
Light, Fragile, and Easily Influenced A young college student’s mind is easily influenced, partially due to a lack of resistance toward outside forces. In the poem “Snapping Beans” by Lisa Parker, the same can be said for the hickory leaf when influenced by the wind. The leaf is the most prevalent symbol in the story. It is an integral piece to the theme of change as one transitions from childhood to the responsibilities of being an adult.
In The Bean Trees by Barbara Kingsolver, Missy, The novel’s main character changes. Said changes are what defines Missy as a whole. These changes occur as a result of Obstacles she comes across and conquers. Such obstacles drive on these changes through either fear or just a lack of will, suppressing her mind and then being confronted with a need for change The reader can see Missy’s first transition when she has a change of heart in the people of Pittman County.
Within the novel “The Bean Trees”, written by Barbara Kingsolver. Within the book, abuse is taken into different terms. Abuse is not only physical, but it can also be categorized as sexual, mental, verbal, psychological, financial, elder, and spiritual abuse. The only four types of abuse that were introduced into the book was sexual, physical, verbal, and The first type of abuse is child abuse.
Leaves containing water-soluble elements were boiled and turned from the solid phase into the liquid phase, boiling water. The calcium carbonate was added to form insoluble calcium salts with the tannins and gallic acid so that after vacuum filtration they would be removed. The sodium chloride salt was added after the vacuum filtration in order to raise the polarity of the water, making less amount of molecules soluble in it. This is because the salt takes the part of the space in water and many compounds become insoluble and are pushed out by the salt.
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
Contaminated water may contain high levels of nitrates and nitrites, causing haemoglobin disorders. Moreover, (April 2015) Environment associations says that most of the people all know that fertilizers are used for proper and healthy growth of plan but are they really healthy and what exactly are fertilizers and how do fertilizers affect the environment. It is a fertilizer is a substance, be it synthetic or organic which is added to the soil in order to increase the supply of essential nutrients that boost the growth of plants and vegetation in that soil. With the rapid increase in population globally, the demand of food and agricultural give in has been rising very highly. This is the reason why statistics show that almost 40-60% of agricultural crops are grown with the use of different types of fertilizers not only this, more than 50 percent
In return, farmers can get a better crop yield at the end of the season. 2)NUTRITIONAL CONTENT: The nutritional content of the crops can also be altered providing a denser nutritional profile comparing to the previous generation of that crop. The UN food and agriculture organization has mentioned that rice has been modified to give higher value of vitamin A and it had helped to reduce global vitamin deficiencies.
