Abstract
The effect of arsenic causes inhibition of seed germination decrease in plant height reduction in root growth, leaf area and photosynthesis and low grain yield.Arsenic and its compounds are known to have adverse health effects on humans, including cancers of the skin, bladder, kidney & lung, and diseases of the blood vessels of the legs and feet and diabetes. Atoms of arsenic bond with other elements forms molecules — if carbon is one of these elements, then the arsenic compound is an organic compound. The toxicity of arsenic is more in inorganic arsenicwhich is a known human carcinogen — organic and inorganic together are referred to as total arsenic. Inorganic Arsenate, Arsenate in ground water have caused tremendous epidemic poisoning across the globe. The persistence of heavy metals in the environment may pollute or contaminate soils and aqueous streams. Rice is cultivated an aerobically, rather than aerobically which leads to much greater arsenic mobilization.High soil arsenic caused by the reduction of phosphate and arsenate uptake through phosphate transporter. The goal of my work is to find method of reduction of arsenic content in rice. Rice is an important staple food for more than 3.5 billion people whodepend upon rice for more than 20 of their daily calories. It is cultivated over an area of 146 million hectares, which produces 474 million tons annually. Rice farming is the largest single use of land for food. India ranks number one globally in area 44 m ha under rice cultivation with 106 mt. production that stands next to China in total production. Our farmers are less aware in the field of use of rice variety specially arsenic tolerant. Although scientist have developed many good varieties of Rice but the information is either not reached to them or seeds are not available to the farmers so that the old variety they use may be not very nutritional, disease resistant and Arsenic tolerant.Instead of making people healthy they may be more effected by arsenic which causes dangerous diseases. Rice growers still face the challenge of meeting food and ecological security and raising standard of living of their families. To sustain even the present level of per capita availability of rice, we have to add another 70-80 million tones by 2050. This can be achieved by adopting long term strategy of crop productivity improvement,Arsenic and diseases resistant variety along with best growth management practice. I have taken this project on Quality and Quantity of Rice production for ecological security and socio economic development of Rice growers and rural people by use of correct suitable variety.
Highlights
The effect of arsenic causes inhibition of seed germination decrease in plant height reduction in root growth, leaf area and photosynthesis and low grain yield.Arsenic and its compounds are known to have adverse health effects on humans, including cancers of the skin, bladder, kidney &
Occurring resistance to high soil arsenic has been observed in some species, which has shown to be caused by the reduction of phosphate as well as arsenate uptake The response of 12 rice varieties to 13.3 μ arsenate was tested
The 40 pair-wise comparisons of beaker reveals a regression of 94% indicating that the vast majority of variance was between individual plants in beakers, rather than between beakers .The variance was confirmed by three-way analysis of variance which indicate that variance and its interaction with the other factors was an order of magnitude lower than the error variance calculated by dividing its root length by the average root length of all 12 control plants

The 40 pair-wise comparisons of beaker reveals a regression of 94% indicating that the vast majority of variance was between individual plants in beakers, rather than between beakers .The variance was confirmed by three-way analysis of variance (factors: genotype, treatment) which indicate that variance and its interaction with the other factors was an order of magnitude lower than the error variance calculated by dividing its root length by the average root length of all 12 control plants.
