Abstract

Roots are organs in rubber plants that play a role in absorbing nutrients, including from inorganic fertilization. The application of mycorrhiza can increase the role of rubber plant roots in nutrient absorption. This research aims to determine the application of mycorrhiza to increase the growth of rubber plants in root trainer nurseries. The research was carried out from April to September 2022 at the Bogor-Getas Research Unit experimental field, Salatiga. The experimental design used a completely randomized design consisting of 8 treatments and eight replications. The treatments in this study were control without fertilization, root fertilizer every 2 weeks, mycorrhiza (5 and 10 g/plant), and a combination of mycorrhiza (5 and 10 g/plant) with root fertilizer (every 2 and 4 weeks). The mycorrhiza treatment (5 and 10 g/plant) with root fertilizer every 2 and 4 weeks showed growth in plant height, stem diameter, root weight, and plant weight, which was not significantly different compared to root fertilizer every 2 weeks. Higher relative agronomic effectiveness compared to root fertilizer every 2 weeks as standard treatment was obtained in mycorrhiza treatments (5 and 10 g/plant) with root fertilizer every 2 weeks (RAE 106% and 135%). These results show that mycorrhiza can increase plant growth and relative agronomic effectiveness without reducing liquid inorganic fertilizer applied through the roots

Abstract

Fluctuating rubber prices cause rubber planters to suffer losses, especially when prices are low as of right now. Planters apply high-intensity tapping to obtain maximum production but this is not balanced with optimal fertilization and actually has a negative impact on the sustainability of rubber plantations. The purpose of this study was to determine the effect of a combination of fertilizing doses and tapping frequency on the productivity of rubber plants and to obtain optimal fertilizer doses and tapping frequency when rubber prices are low. The research method used a randomized block design (RBD), with six combination treatments of tapping frequency and fertilization. The results showed that the highest volume of latex was produced in the S/2 d3 ET treatment of 2.5% 100% fertilization, while the variable dry rubber content (DRC), tapping frequency treatment d3 (B, D, F) produced higher DRC and was significantly different compared to tapping frequency treatment d2 (A, C, E). The highest KKK was obtained in treatment F, namely 38.6%. Observation of individual plant production (g per tree per tapping), 50% - 100% fertilization treatment can increase the production of both tapping frequency d2 and d3. The highest production was obtained in treatment F (S/2 d3 ET2.5% 100% fertilization). So, tapping with d3 tapping frequency combined with 100% fertilization dose produces the highest individual plant productivity. Tapping with d3 frequency combined with 50% fertilization can be an alternative when the rubber price is low.
