The arsenic (As) contaminated soil and irrigation water of crops that has existed for a long time in An Phu district, An Giang province, Vietnam reduced the crop yield and was harmful to people's health. Application of inorganic manures combined with the lime amendment, which is the best way to decrease the As absorption and raise yield of mungbean was carried out the farm experiment during January to april of 2021. The field experiment, which was performed the same time designed with six treatments of three lime ratios: 0, 4 and 6 tons CaO per ha for the river water irrigation (L1, L2 and L3 treatment) and 0, 4 and 6 tons CaO per ha for the deep well water irrigation (L4, L5 and L6) and NPK fertilizer with four replications at An Phu district, An Giang. This study was shown that all deep wells were polluted by the high As concentration. Furthermore, local farmers irrigated their crops from these deep wells and its relationship with the movement and uptake in mungbean. The positive interaction among As contents of the deep well waters, crop soils, and seeds with The correlation coefficients. Four lime treatments (both irrigated waters) decreased As contents of stems (63.5%) and seeds (65.7%) and increased the yield of mungbean (33.3%) compared to the treatment of no lime and deep well water irrigation. The higher ratio of lime amended, the lower As concentration of stems and seeds. Amendment of 6 tons CaO and river water irrigation produced the highest yield (2.70 t/ha) and lowest As contents of stems (416 ppb) and seeds (192 ppb). [ABSTRACT FROM AUTHOR] |
