Alleviation of adverse effects of saline water irrigation on maize hybrid by the external application of chemical protectants and organic manures


Author(s): Nandhini Devi B and T Chitdeshwari

Abstract: A field experiment was conducted to alleviate the salinity stress induced through saline water irrigation on the growth and yield of maize hybrid using chemical protectants and organic manures. The maize hybrid CO 6 was grown under saline water irrigation having a water salinity of 6.3dSm-1 in a black clay loam soil. Different organic manures (FYM, Vermicompost) and chemical protectants (acetyl salicylic acid (0.1mM), potassium chloride (1%), potassium nitrate (0.5%) and pink pigment facultative methylotrophs (1%) were tested for their significance in mitigating irrigation water induced saline stress on maize hybrid. The study revealed that, foliar spraying of 0.1 mM acetyl salicylic acid thrice at 30, 45 and 60 days after sowing along with basal soil application of 5t vermicompost ha-1 registered the highest grain and stover yield in the maize hybrid. Higher crop yield and growth was positively correlated with better biochemical compounds (soluble protein) and antioxidant enzyme activities (catalase, peroxidase, superoxy dismutase). This was closely followed by the foliar addition of 0.1 mM acetyl salicylic acid thrice plus 12.5 t FYM ha-1. Combined effect of organic manures and chemical protectants gave better response than the individual effects.
