Text 3: My research work

I am a first year postgraduate student of the Perm State Agricultural Academy. I’m doing research in agronomy which aims at increasing the yields, fertility of soil and improving the quality of crops. My special subject is crop growing.

My research is both theoretical and practical and is devoted to the study of spring cereal grains yield formation in the Urals. I have been working on the problem for three years. I got interested in it when a student.

I think this problem is very important nowadays for our region. Spring cereal grains are very valuable crops in organic farming, and much effort has been put into optimizing the yield and quality of organically grown spring cereal grains. The necessity of searching efficient strategies of optimizing the yield and quality of organically grown spring cereal grains determines the motivation for the study.

The subject of my thesis is the influence of changing crop varieties and meteorological conditions on spring cereal grains yield, its quality and phytosanitary state.

The theoretical significance of my work is that it may be used as a guide for other scientific works in optimizing the yield and quality of organically grown spring cereal grains.

The practical value of my thesis is that the developed methods and obtained results may be used in agricultural practice to increase the yield and improve the phytosanitary state of spring cereal grains.

My research work consists of several stages. They are: analysis of scientific literature, selection of crops and variety, development of plans and methods, field experiment, analysis of obtained results. The experiment will be carried out on the field of the Perm State Agricultural Academy.

My work is based on the theory developed by my research supervisor, Professor S. Petrov. He is head of the department at the Perm State Agricultural Academy. I always consult him when I encounter difficulties in my research. We often discuss the collected data. These data enable me to define more precisely the theoretical aspects of the spring cereal grains yield formation. I have not completed the experimental part of my thesis yet, but I’m through with the theoretical part.

I take part in various scientific conferences where I make reports on my subject and participate in scientific discussions and debates. The results of the research are presented at scientific conferences. For the moment I have 4 scientific papers published.

I’m planning to finish writing the thesis by the end of the next year and prove it in the Scientific Council of the Perm State Agricultural Academy. I hope to get a candidate’s degree in agriculture.
