Growth Potential of Two Agroforestry tree species under salt stress condition

Abstract

Cultivable soils are declining worldwide as well as in Pakistan owing to rise in salinity level within soil leading the world toward food shortage. Significant option in this scenario could result in evaluation of salt tolerant species in important agricultural areas of the world extremely influenced by soil salinization. Therefore, current study of seventy days’ trial period was designed to explore the growth potential of Euclyptus camaldulensis and Syzigium cumini in salt-affected soil of Bahawalpur. Three treatments carried out to check the impacts of sodium chloride over growth parameters, of Euclyptus camaldulensis and Syzigium cumini on saline soil using Randomized Complete Block Design (RCBD) having factorial arrangement with three replicates. Soil parameters were also determined before and after planting the Euclyptus camaldulensis and Syzigium cumini. Sodium chloride in Control (0.7g) Medium (0.14g) and in high (0.21g) doses applied under treatment groups in separate form. Results have shown significant treatme effect and plant height was significant reduce salt stress conditions. The maximum height was observed for Medium doses in Euclyptus camaldulensis (60.9cm) in fig 2.4 and lowest in Syzigium cumini (18.1cm) in .maximum height for stress was observed for Control in Euclyptus camaldulensis (39.2) in and lowest in Syzigium cumini (19) in fig 2.4 The maximum height was observed for high in Euclyptus camaldulensis (20.9cm) and lowest in Syzigium cumini (10.9cm) .Effect of salt stress within species was significant that shows salt stress significantly reduce stem fresh weight. Maximum stem fresh weight for control was observed in Euclyptus camaldulensis (7.70gm) and, Syzigium cumini (5.7gm), The present study results showed that treatment effect was significant for root fresh weight maximum results for control were shown by Syzigium cumini (18.64gm)in control followed Euclyptus camaldulensis (11.39gm) high, The present study shows that  maximum result for stress observed in Eucalyptus camaldulensis
