Influence of Irrigation Systems on the Plant Growth and Leaf Ratio Analyses of Rubber (Hevea brasiliensis) Seedlings

The sprinkler irrigation system is the most widely used for rubber in a nursery. However, method associated with high water loss during irrigation. In view of this, an experiment was conducted to assess effect different systems on growth dynamics, leaf ratio analyses, productivity, and use efficiency seedlings. treatments were systems; soil + overhead (CON), growing media (GM) drip (DRP), GM capillary wick (WCK), (SPR). Each treatment replicated three times, laid out randomized complete block design. results showed that DRP WCK had significantly (p<0.05) higher seedlings’ parameters by 15–39% than obtained SPR CON. DRP, WCK, statistically comparable root length volume 14–43% relative Similar trends plant such as crop rate (CGR), area index (LAI), observed all treatments. CON lower CGR LAI, which could be attributed retention treatment. productivity 56–60% (SPR CON) 84% WCK. are best this study because their application uniformity led dynamics productivity. due lack uniformity, leading other irrigations. shows potential more cost-effective its recurrent cost labor
