Effect of Saline Water on Physicochemical Properties of Soil Used in Plastic Nursery Bags of Three Months Olive Sprouted Cuttings under Tunnel Conditions by Muhammad Arshad Ullah in Current Investigations in Agriculture and Current Research in Lupine Publishers
The quality of irrigation water has the potential to significantly affect soil structural properties. The study was carried out at NARC Islamabad during August, 2017 to October, 2017 to investigate the effect of saline water on the soil characteristics as well as ionic concentrations in 4 olive varieties i.e. Uslo, Coratina, Carolea and Moraila having 3 months sprouted olive cuttings under different saline water treatments in tunnel. Six levels of saline water were artificially developed (ECw=0,2,4,6,8,10dSm-1). Completely randomized design was applied with three replications. Olive cuttings were irrigated with six saline water three times in a week. Results of this study indicated that soil pH was mentioned no differences with saline water irrigations among three olive varieties. However minute changes in soil pH were noted. Soil ECe was increased as well as the salinity of irrigation water was increased. Soil Na determined increasing trend as the salinity of irrigation water increased. Decreasing trend in soil K was noticed against the increasing of salinity levels by saline irrigation waters. Soil Ca+Mg described the increasing behavior as the salinity of irrigation water increased. Na+ in leaf olive tissues showed increasing behavior as the salinity of irrigation water increased. No difference was observed among three olive varieties. In leaf olive tissues showed increasing trend as the salinity of irrigation water increased. But the increasing trend is very minute as compared to the increase in Na+.
