Soil Nutrient and Rice (Oryza sativa L.) Growth Characteristics under Different Arsenic Contamination Levels

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

Straighthead Disease of Rice (Oryza sativa L.) Induced by Arsenic

Effect of Copper Contamination on Soil Biochemical Activity and Performance of Rice (Oryza sativa L.)

Copper (Cu) is an essential element for regular functioning of organisms. It plays significant role in number of physiological processes like photosynthetic and respiratory electron transport chains, N fixation, protein metabolism, cell wall metabolism, anti oxidant activity, fatty acid metabolism and harmone perception. However, excessive amounts of Cu in the root zone inhibit growth, chlorosi...

Growth-inhibition patterns and transfer-factor profiles in arsenic-stressed rice (Oryza sativa L.)

Arsenic (As) accumulation in rice owing to uptake from the soil is a critical human health issue. Here, we studied the chemical properties of As-treated soils, growth inhibition patterns of As-stressed rice plants, changes in the As content of soil and soil solutions, and the relationship between As accumulation and As transfer factor from the soil to the rice organs. Rice plants were cultivate...

Correlation Studies in Rice (Oryza sativa L.)

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
