Abstract
The experiment was conducted to study the effect of salinity levels (ECe value 0, 2.5 and 5.0 dSm-1) on sugarcane genotypes (CoP 9702, CoP 112, BO 154, BO 153 and CoP 9301) under NaCl induced salt stress condition in glasshouse at Sugarcane Research Institute, Pusa, Bihar. The increasing salinity levels from 0 to 5 dSm-1 ECe significantly decreased germination, plant height and plant population indicating stunting of growth under salt stress condition. The ECe value of 5.0 dS m-1 leads to overall reduction in germination (30.28%), cane weight (25.72%) cane yield (28.05 %) and sugar yield (33.25%) over control. Among sugarcane genotypes, BO154 followed by CoP112 recorded significantly superior as compared to rest of the genotypes in terms of growth parameters and yield. The genotypes, BO154 attained maximum germination, plant height and cane yield followed by CoP 112 and lowest in COP 9301. The reduction in cane yield among the genotypes were in order of BO154 > CoP112 > CoP 9702 > BO153> CoP 9301. The value of brix, pol and juice recovery significantly decreased with increasing level of salinity, however purity coefficient remains unaffected. The mean sugar yield increased by 9.66 % in BO 154 and 5.44 % in CoP 112 over BO 153. Sugar yield, a function of cane yield and exhibited similar trend of cane yield. The salt stress caused increased concentration and uptake of Na+ and Na+/K+ ratio in sugarcane leaf. BO 154 and CoP 112 performed better by maintaining lower Na+/K+ ratio. The increase in Na+/K+ ratio was observed in salt sensitive genotypes viz. CoP 9301 and BO 153. The pH and EC of post soil increased while organic carbon of soil decreased significantly with increasing level of salinity. The Cl- content of soil varied significantly (16.54 - 26.67 mel-1) due to salinity. Among sugarcane genotypes BO154, followed by CoP112 performed well in terms of sugar and cane yield under influence of salt stress and it may be grown as salt tolerant genotype in agro-climatic conditions of North Bihar.
