Potassium (K) is one of the sixteen essential nutrients required for plant growth and reproduction. It is not only a constituent of any plant structure or compounds but also plays a vital role in photosynthesis, translocation of ions and their balance, regulation of stomatal opening and closure, water use efficiency and activation of at least 60 enzymes. Potassium is the most abundant cation in the cells of non-halophytic higher plants (Maathuis et al., 1997). It is absorbed by plants in higher amounts than any other mineral element except nitrogen (Daliparthy et al., 1994). Kafkafi (1990) suggested that the luxury storage of K by cotton plant can be both beneficial for higher yields and a cheap source of insurance against possible K-deficiency …show more content…
These deficiencies cannot always be corrected by potassium soil application especially at later stages of plant growth and this will be effective only for the next crop (Weir, 1998). However, foliar applications of potassium may be useful to overcome these deficiencies more quickly and efficiently (Hassan and Arshad, …show more content…
Essington et al., (2002) found that modern cultivars grown on loess derived soils were particularly prone to potassium deficiency. Conventional and Bt cotton cultivars showed differential responses to potassium deficiency (Makhdum et al., 2007; Zhang et al., 2007). Cotton leaf growth, chlorophyll content and photosynthesis are the most sensitive physiological process in potassium deficient conditions (Pettigrew, 1999).
Aladakatti et al. (2011) compared the soil and foliar application of potassium and he concluded that the soil application of potassium (40 kg/ha) with recommended dose of nitrogen and phosphorus (80 & 40 kg/ha) is essential for getting higher seed cotton yield and better quality fiber. But along with the application of recommended dose of N:P:K (80:40:40 kg/ha) and two foliar sprays of K with 1 % MOP each at early (90 DAS) and peak boll formation stage (110 DAS) can increase seed cotton yield with marginal improvement in fiber qualities and net
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.
If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle
After the destruction of the Caddoan villages, the Osage were able to fully exploit the large buffalo herds of the plains region. Camped along the Salt Fork of the Arkansas River (present north-central Oklahoma) the Osage hunted the plentiful buffalo, which became their main source of food. Hunting took on a much greater level of importance while the Osage relied less on agriculture to fill their stomachs. The Osage spent increasing amounts of time away from the village hunting.
In my honest opinion solitary confinement in the U.S. is not justified and only does more harm than good. Not only is it a rash punishment, but it is one of the worst kinds of psychological tortures that could be inflicted upon an inmate. Human beings are undoubtedly social creatures and without the mere contact of another person the mind decays and ultimately leads a person to anger, anxiety, and hopelessness. Psychologists also claim that solitary confinement and isolation in general also cause depression or the loss of ability to have any "feelings", cognitive disturbances, such as confused thought processes and disorientation, perceptual distortions, such as hypersensitivity to noises and smells, distortions of sensations, and hallucinations affecting all five senses, as well as paranoia and psychosis which often times involve schizophrenic type symptoms, and finally, the worst of all symptoms, being self-harm such as self-mutilation, cutting and even suicide attempts.
A month after Abraham Lincoln became president of the United States. He was pursing to abolish slavery on December 6, 1864. This was known as the 13th amendment. Lincoln did purse abolishing slavery even though he was executed in April. On December 18th, this amendment was authorized.
Further, in order to absorb water and other nutrients from the soil the roots were developed to anchor the plant to achieve this purpose. Material transportation: In the water, different parts of the plant get nutrients and water directly from their environment,
Discussion Besides our maze, we would like to suggest another teaching aid or game for young children who have dyslexia. Our suggestion is drumming. Drumming is one of the way where children can express their feelings through beating the drum and listen the sounds based on their different sounds. As we know that, children who have dyslexia usually have the difficulty in reading. Well, to some people, children who have dyslexia sees something as a visual issue.
Description Peculiar Benefits is a memoir written by Roxane Gay. According to Roxane Gay (Peculiar Benefits May 16, 2012, para. 2) " To this day, I remember my first visit and how at every intersection, men and women, shiny with sweat, would mob our car, their skinny arm stretched out hoping for a few gourdes or American dollars." In the second passage of peculiar benefits Roxane Gay made reference to a genuine past experience, making the reading a memoir. Peculiar Benefits centralizes on Roxane Gay's assesment on privilege and her emotion towards self-delegated privilege police.
The plants with 200 ml topsoil were projected to have the highest average height according to the original hypothesis of increased plant growth due to an increase on the amount of topsoil added. Moreover, the original hypothesis was refuted as the plants with no topsoil in the control had a higher average height than the plants with 25 ml topsoil. The mixed red and green color on the leaves of the plants with 25 ml topsoil indicated possible deficiencies in phosphorus which might have slowed their growth. Moreover, the mixed red and green color on the leaves of the plants in both 100 ml and 200 ml topsoil also indicated a possible phosphorus deficiency which may have resulted in the slower growth of the plants despite having greater amounts of topsoil. The experimental results might have skewed due to the over fertilization of the radish seeds which might have led to excess nutrient levels which are unsuitable for radish plants as they require little to no fertilization for growth (Chase, 2018).
Gunpowder, one of the most necessary inventions, was invented in East Asia and it is essential to bring it back to its rightful place. Gunpowder would be extremely beneficial to China because it can be used in the military, it helps make TNT and TNT helps to create canals and roads. It also creates fireworks which could be used in trade and entertainment. Gunpowder helps to construct canals and roads by using the TNT to blow up rocks and it expands areas and creates room to build the canals and roads. The canals and roads will also provide transportation.
Introduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
The overall project goals and central questions that has to do with the project is mostly trying to determine the isotonic concentration of the salt in potato roots and the use of the ideal soil salt conditions for the potato plant growth. In part 2, we had to test the enzyme activity that is in the was involved in the potato, so we can also determine the ideal soil pH conditions for the potato plant growth. In part 3, we were able to test absorb the leaf pigment at various wavelengths that determine the optimum light absorption conditions and was able to make recommendations for the light conditions that would be used un greenhouses. The goal of the first project is to determine the ideal soil salt for potato roots and we can relate this to the project is to find out if Solution A or Solution B has more solute in it. The goal of this project is to determine the meaning of Osmosis.
This experiment is an attempt to investigate the amount of water potential across root storage plant species. The root storage plant species that shall be used are the carrot and the potato and the method that shall be used is known as Chardakov’s method. Water potential is the tendency of water to enter or leave a cell. Water moves from an area or region of low water potential to an area of high water potential. It is important to note that the highest water potential is 0(the water potential of pure water) and the other water potential values are in negative numbers .
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.
Fertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.
