Plant Factors in Nitrate Accumulation
Nitrate Poisoning Farmers and ranchers depend on the successful combination of livestock and crops. Forage crops, in particular, are important to the producer, but they should be monitored due to plant toxicants that can be a problem. One toxicosis of concern is Nitrate (N03 ) toxicity. Nitrate toxicity of cattle was noted as early as 1895 with corn-stalk poisoning. However, at that time nitrat...
متن کاملUptake and nitrate accumulation affected by partial replacement of nitrate-N with different source of amino acids in spinach and lettuce
As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...
متن کاملSelection and breeding of plant cultivars to minimize cadmium accumulation.
Natural variation occurs in the uptake and distribution of essential and nonessential trace elements among crop species and among cultivars within species. Such variation can be responsible for trace element deficiencies and toxicities, which in turn can affect the quality of food. Plant breeding can be an important tool to both increase the concentration of desirable trace elements and reduce ...
متن کاملeffects of chemical fertilization and organic fertilizer on spinach (spinacia oleracea l.) yield and nitrate accumulation.
in order to studying the effect of conventional fertilization and organic fertilizeron growth, yield and nitrate accumulation of spinach, a greenhouse experiment was carried out in factorial based on random complete design with three replications in a commercial greenhouse located at lahijan. treatments were three levels of municipal soil waste compost (0, 50 and 100 t ha-1), five chemical fert...
متن کاملNitrate and Nitrite: Sources, Impact on Human Health and Reduction of Nitrate Accumulation in Agricultural Products Using Bio-fertilizers
Nitrate with the chemical formula NO3- is one of the forms of nitrogen in the environment that plays an important role in the nitrogen cycle. Vegetables, water and meat are important sources of nitrate. Nitrate is made in the body through the arginine-NO pathway and enters the body through various sources. Oral nitrate is converted to nitrite (NO2-) by bacteria when it enters the mouth, and nit...
