“…The INM approach relies on the use of all possible natural and synthetic sources of plant nutrients and the implementation of soil management techniques to avoid nutrient losses and to improve soil functioning (Gruhn et al 2000). We found a few relevant papers dealing with the use of organic fertilizers in immature rubber plantation (Abraham et al 2015;Ardika et al 2017). In contrast, the management of the soil cover during the first years of a rubber plantation is well documented.…”

The rapid expansion of rubber tree plantations in recent decades has been accompanied by dramatic negative ecological and social impacts. Rubber sector stakeholders consequently engaged in sustainable production of rubber. Despite the lack of harvest during the immature stage following planting, this period plays a key role in future yields. Management practices, particularly fertilization regimes, are used by farmers to shorten the immature period as much as possible. This entails maintaining or even improving the productivity of existing plantations to face the demand for natural rubber. This review focuses specifically on the immature period of rubber tree plantations, as it is the most critical period for nutrient management. We reviewed available knowledge on fertilization practices, soil management, and nutrient dynamics in rubber plantations with the goal of developing a nutrient balance approach for this crop. Our review revealed (1) a notable difference between fertilizer recommendations made by technical institutes and those reported in the scientific literature; (2) that even though nutrient diagnostic methods could help growers adapt the fertilization of rubber trees more than 3 years of age, further studies are needed to adapt current methods to the wide range of cultivation areas; and (3) that the nutrient budget approach may be the best way to incorporate the variety of rubber tree cultivation conditions. In conclusion, the nutrient budget method is a promising way to improve the sustainability of rubber plantations through fertilization making it possible to increase nutrient use efficiency. A comprehensive approach based on nutrient budgets requires further in-depth studies to examine nutrient dynamics in a wide range of conditions, including intercropping and logging residue management between clearcutting and replanting.

“…Therefore, the treatment with the least newly developed flush had most of the fully expanded leaves still intact. Flush formation on the immature rubber was reported to be affected by the availability of nutrients, especially N [26]. On average, NPK treatment showed the highest flush formation with 3.70 ± 0.48 formed flush, followed by NP (-K) and NK (-P) consecutively, and it was significantly different with PK (-N) and Control (-NPK) which showed 3.10 ± 0.32 and 3.00 ± 0.00 formed flushes.…”

The Dynamics of Immature Rubber Photosynthetic Capacities Under Macronutrients Deficiencies

Pará rubber produces natural latex which is essential for the industries. Rubber plant in immature phase is prone to macronutrient deficiencies due to improper management practices in the field and the nature of immature plants that have sensitive physiological responses under stress conditions. The study aimed to assess the effect of macronutrient limitation on immature rubber trees’ photosynthetic capacity and growth. The immature rubber was pot-grown inside the greenhouse with a completely randomized design experiment and nutrient limitations used as the treatments. The treatments consisted of 5 levels, namely, NPK; NP (-K); NK (-P); PK (-N); Control (-NPK). Photosynthetic capacity parameters (Vc max: maximum rate RuBisCO carboxylation, Jmax: RuBP regeneration rate, and TPU: Triose Phosphate Utilization), tree growth (plant height, flush number, leaf number, stem diameter), and leaf macronutrient (N, P, and K) concentrations were periodically measured. Welsch’s test (α = 0.05) continued with Games-Howell pairwise comparison, followed by Pearson’s correlation test and polynomial regressions were performed to describe the nutrient limitation and photosynthetic capacity relationships. Results showed that the leaf nutrient concentration corresponds with the given treatments, even though it was above the critical level for immature rubber. The limitation of N fertilization slightly reduced plant development and growth such as height, leaf number, flush number, relative growth rate, and photosynthetic capacities. However, the P and K limitation effect could not be observed clearly in the observation periods on growth and photosynthetic capacity parameters. Furthermore, the mobility rate of nutrients from the soil to the plants and its translocation inside plant organs played more essential role in plant growth and photosynthetic capacities. Prolonged observation periods on various rubber clones have to be performed to deeply understand the effects of nutrient deficiencies on immature rubber tree morphophysiological activities. HIGHLIGHTS Rubber plant in immature phase have sensitive physiological responses under stress conditions, and it is prone to macronutrient deficiencies due to improper management practices in the field Assessment of macronutrient limitation effect on immature rubber trees’ photosynthetic capacity and growth is essential to understand how the plants strive under the nutrient scarcity and providing a perspective which nutrient is more essential The N fertilization played more essential role compared to P and K, for immature rubber growth and photosynthetic activity GRAPHICAL ABSTRACT

“…Teknologi ini sudah umum digunakan untuk pembibitan tanaman (Bashir et al 2009;Rashid et al 2018), namun untuk tanaman karet masih tergolong baru. Pada awalnya teknologi ini diperkenalkan di India untuk memudahkan pengangkutan di daerah berbukit, dan pada saat ini mulai diadopsi di negera-negara penghasil karet alam lainnya, termasuk Indonesia (Ardika dan Herlinawati, 2014;Ardika et al 2017). Penelitian Putra et al (2018) menunjukkan bahwa penggunaan pupuk organik briket rawa pening dapat meningkatkan biomass bibit karet.…”

The rubber tree rootstock nursery using the root trainer method is aimed to promote root growth through the use of non-soil growing media in a special container. This technology offers the advantages of a shortened breeding process, good rooting, and ease of delivery. The objective of this study is to investigate the effect of the planting media composition of oil palm bunches compost, manure, rice husk, solid decanter, and Trichoderma viride on the growth of rubber rootstock under the root trainer method. The research was carried out in the greenhouse of the Sungei Putih Research Center, Indonesian Rubber Research Institute, Deli Serdang, North Sumatra in January-May 2019. The observation included plant height, number of leaves, stem diameter, dry weight, and root length, and successful grafting percentage. The results indicated that the mixture of oil palm bunches compost, solid decanter, and Trichoderma viride (Te treatment) was the most potential to be developed as a planting media for rubber rootstock nursery under root trainer system. At 18 weeks after planting, the Te treatment had an average height of 82.66 + 14.27 cm with an increment rate of 3.25 + 0.81 cm/week, number of leaves 11.33 + 3.21 leaves with the increment of 0.52 + 0.20 leaves/week, stem diameter 5.29 + 0.73 mm with an increase of 0.33 + 0.05 mm/week. The Te treatment had a length and root weight of 41.97 + 2.40 cm and 1.68 + 0.77 g, respectively, with the grafting successfulness percentage of 47.37%. Besides showing good growth, these materials are also available in large and continuous quantities. The use of Trichoderma viride not only for increasing plant growth but also as a biocontrol of white root disease. Keywords: growth, growing media, Hevea brasiliensis, rootstock, root trainer
