Not AvailableThe effect of high residual sodium carbonate (RSC) irrigation water and its neutralization with gypsum/H 2SO4
on sorghum [(L.) Moench] was evaluated in a micro-plot experiment during rainy () season
(May to September 2013) at ICAR-Central Soil Salinity Research Institute, Karnal, Haryana. The experiment was
conducted in randomised block design, consisted of 5 treatments of different RSC levels [RSC nil (control), RSC
5meq/L, RSC 10meq/L, RSC 10meq/L (neutralized 5meq/L with gypsum), RSC 10meq/L (neutralized 5meq/L
with H2SO4)] with 4 replications. Increase in concentration of RSC in water from RSC 5 to 10 resulted in reduction
in growth parameters like plant height, leaf to stem green biomass, leaf area index, but extent of reduction was
lesser, while using RSC water reclaimed with gypsum and sulphuric acid. Neutralization of RSC in irrigation water
with gypsum proved a safer and economical option to use high RSC groundwater for irrigation of sorghum for profitable
fodder production as compared to sulphuric acid.Not Availabl
