salinity regimes on the growth and physiology of sugarcane A split-plot experimental design using and was used Biochar as a main factor include five application rates (0, and 10 tons ha-1), while salinity condition as a sub factor included non-salinity and salinity conditions Non-salinity condition is achieved by irrigating with a fully tap water during the growth of sugarcane plants Salinity condition was done by irrigating with salinity water at seedling stage (2 months after transplanting to pots) Specifically, plants in each pot were watering with 200 ml of 100 mM NaCl solution for around 10 days once every day Each of 102 plastic pots (260 mm diameter × 210 mm height) was filled with a old alluvial soils obtained from experimental field at Vietnam National University of Agriculture, Hanoi, Vietnam Each pot contained 12 kg of dry soil The biochar was applied at 0; and 10 tons biochar/hectare respectively 0; 35 and 70.65 gram biochar/pot before transplanting sugarcane The results showed that under effects of stress, sugarcane growth was inhibited with reductions in plant height, plant diameter, total leaf number, leaf area, SPAD, partial and total dry weights Under salinity condition, application of biochar at and 10 tons ha-1 to the soil increased plant height, plant diameter, root length, leaf area, the fresh and dry weight, Fv/Fm, the chlorophyll content while decreased the water saturation deficit in the leaves and the relative ion leakage The findings suggest that biochar application at 10 tons ha-1 could be recommended for ensuring the best growth and physiological parameters of sugarcane plants ix SE(N= 5%LSD 6) 10DF 0.170655 0.537741 NL NOS 6 0.281367E-01 0.146781 0.886598E-01 0.462511 0.205945 0.648939 RE3 2.56333 2.71500 2.65500 SE(N= 6)
