ABSTRACT
The use of saline irrigation water leads to the buildup of salts in root zone, resulting in decreased yield and deterioration in soil resource. Continues use of organic manures, help in the reduction of salt concentration in the root zone. Organic matter was used to mitigate the negative effects of saline water irrigation using sorghum as test crop during summer, 2018. In this experiment water of 3 different types was applied coupled with addition of organic matter at 2 different rates. The experiment comprised of 9 treatments having 4 replications; T1 = canal water, T2 = saline water having EC value 2 dS m-1, T3 = saline water having EC value 3 dS m-1, T4 = T1 + organic matter @ 5 Mg ha-1, T5 = T2 + organic matter @ 5 Mg ha-1, T6 = T3 + organic matter @ 5 Mg ha-1, T7 = T1 + organic matter @ 10 Mg ha-1, T8 = T2 + organic matter @ 10 Mg ha-1 and T9 = T3 + organic matter @ 10 Mg ha-1. The experiment was laid according to randomized complete block design (RCBD). Sorghum cultivar “Hegari” was grown as a test crop. Data regarding plant parameters such as height of sorghum plants, diameter of stem, number of plants/ m2, total biomass of fresh plants were noted. Among all the treatments, T7 (T1 + organic matter @ 10 Mg ha-1) performed the best which produced the highest values of growth parameters. However, the treatment T3 (water of EC 3.0 dS m-1) proved inferior to all others with respect to height of sorghum plants, diameter of stem, number of plants m-2, total biomass of fresh plants. All the collected data were analyzed by using statistix 8.1, ANOVA technique and significance of treatment were compared by using Tukey’s (HSD) test at 5% probability level.
