ABSTRACT

Irrigation with saline water is a key issue affecting crop growth. Saline irrigation has drastic effects, limiting normal physiological activity and productive capacity of crops. The saline water irrigation leads to salt accumulation in the vicinity of roots which results in reduced yield along with soil deterioration. Organic matter application can prove helpful in keeping the salt level low in root rhizosphere. To check the efficacy of organic matter in mitigating the harmful impacts of salty water irrigation on soil characteristics, this trail was conducted. The irrigation water of 3 different types (canal water and saline water of electrical conductivity values 2 and 3 dS m-1) were used alone and with farmyard manure (FYM) at 5 and 10 Mg/ha. This trial comprised of 09 treatments which were; T1 = irrigation of canal water, T2 = irrigation of EC 2 dS m-1 water, T3 = irrigation of EC 3 dS m-1 water, T4 = T1+ FYM at 5 Mg/ha, T5 = T2 + FYM at 5 Mg/ha, T6 = T3 + FYM at 5 Mg/ha, T7 = T1 + FYM at 10 Mg/ha, T8 = T2 + FYM at 10 Mg/ha and T9 = T3 + FYM at 10 Mg/ha. The design of research study was randomized complete block design (RCBD) with four replications. The test crop was sorghum cultivar “Hegari”. Analysis of soil was carried out for various characteristics like pH, EC, SAR, organic matter, phosphorus, and potassium in soil before sowing and after harvesting sorghum. The best performance was observed in T7 (canal water + FYM at 10 Mg/ha) which improved soil properties by lowering pH, EC, and SAR and enhancing concentration of organic matter, phosphorus and potassium. However, T3 (water of EC 3 dS m-1) increased soil electrical conductivity, pH, SAR, and lowered organic matter, phosphorus and potassium concentration. Data were statistically analyzed by statistix 8.1 ANOVA approach along with Tukey’s test (HSD) at probability level of 5% for comparing treatments significance.
