Response of rice to various forms of arsenic in soil



Response of rice to various forms of arsenic in soil



Proceedings of the 30th Annual Meeting of the Southern Weed Science Society: 373



A study was carried out to investigate possible toxic effects of arsenical residues on rice grown on sites formerly used for cotton production. MSMA, cacodylic acid and calcium arsenate were applied at 1.1, 3.4 and 10.1 kg As/ha harrowed-in just before sowing rice. MSMA had little influence on the vegetative growth of rice but caused a high incidence of sterility and severe yield depressions.
