It is often considered to be a science dealing with eco-regions as it depends largely on climate and properties of soil in a particular area. These factors vary largely from one place to another. Many individuals are of the opinion that agricultural science depends on the local weather and local soil characteristics, so specific crops need to be studied locally. History The path breaking work of Gregor Mendel in the field of agriculture made its study very popular around the world. However, in the
The effect of minimum, low or no till on plant disease development. Minimum, low or no till are all practices of cultivation on a soil bed. Will shall discuss methods and cultivations and the effect each of them have on disease development. Will look at both the advantages and disadvantages and look at some ways to prevent the plant disease development in a crop. We will also look at some experiments carried out on the cereal and grass crops to gain an insight on which methods suffers the most from disease development.
To accurately predict rainfall, the cloud status and sky status must be known. Previously many techniques of image processing have been carried out successfully. Image processing techniques can be used to measure the cloud, sky, rain status. Rainfall being an important part of agriculture helps in productivity of various vegetables, fruit, flowers etc. Some of the products of flower, crop, and vegetables are exported.
Research Title: Genetic and Epigenetic Characterization of Non-Nuclear DNA in Rice Aim: The primary aim of this research is to study the epigenetics mechanisms occur in the non-nuclear DNA of rice plants. The research aims to investigate the epigenetics characteristics found in rice mitochondrial genome across different tissues at different developmental stages of rice plants. A comparative mitochondrial epigenetics between different rice subgroups will be explored in this research as well. This research also aims to investigate the compare the epigenetics differences exist between amyloplasts and chloroplasts in rice. Summary: Rice, being an agricultural crop serves as a source of carbohydrate while providing essential vitamins and minerals
Seed marketing takes place through officially recognized seed outlets, and by way of national agricultural research systems (Louwaars 1994) and even through relief seed programs. The central premise of the formal system is that there is a clear distinction between ‘seed’ and ‘grain’. Formal systems are especially important when seed is used to grow crops for commercial purposes (for example export or further food processing) and the uniformity and high quality of the product has to be guaranteed. The informal seed system is basically what the formal system is not. Seed related activities tend to be integrated and locally organized, and the informal system embraces most of the other ways in which farmers themselves produce, disseminate and procure seed: directly from their own harvest, through barter among friends, neighbors and relatives, and through local grain markets or traders.
Chapter-3 Phytosociological Analysis Introduction In this chapter focuses and deals with Quantitative vegetation explanation of plant communities. Phytosociology involves plant communities within a habitat, their floristic composition, development and the social relationships between them. Probably every science has periods in its development when some phase was in fashion and courted by the scientifically sophisticated. In botany, emphasis has at one time or another been placed on taxonomy, geography, ecology, physiology, vascular anatomy, embryology, cytology, genetics and molecular biology. In the same way, ecology has experienced vogues in the study of physiological ecology, growth-form adaptation, succession, quadrat analysis of
Many technologies are improved to decrease the water consumption and human involvement in the particular task in an agricultural field. This paper mainly deals with the survey of different technologies used in agriculture. INTRODUCTION
2.3 Land use/Land covers Change Detection An increasingly common application of remotely sensed data is for change detection. Change detection is the process of identifying differences in the state of an object or phenomenon by observing it at different times(Bottolomy, 1998). Change detection is an important process in monitoring and managing natural resources and urban development because it provides quantitative analysis of the spatial distribution of the population of interest. Change detection is useful in such diverse applications as land use change analysis, monitoring shifting cultivation, assessment of deforestation, and study of changes in vegetation phenology, seasonal changes in pasture production, damage assessment, crop
