Plant breeding is the main motor of our research and development efforts. Facilities development and enrich the material genetics continue to improve and discover the higher quality planting materials, especially oil palm and cocoa commodities. We have released seven high yielding varieties with genetic basis and different advantages.

Conventional breeding is supported by biotechnology in which work together to a common goal with the main focus to get the Ganoderma resistant planting materials, supports harvesting efficiency, high oil content and high yielding per hectare.

Meanwhile, the quality management system production Lonsums, breeding seeds and biotechnology, all of which have obtained recertification of ISO 9001: 2008.


Agronomy division focus on advisory works including, replanting, land preparation, new planting, immature and mature monitoring. Analysis of crop yield level and palm health are identified carefully by considering palm condition (K1), estate condition (K2), infrastructure (K3), natural resource and climate (K4), social (K5) and Management (K6). Furthermore agronomy division also carry out field trials to response the operational queries including both in-organic and organic fertilizer, castration, monitor block, plant density and soil survey.

Utilisation of mill waste into compost as organic nutrient source is also the agronomy emphases by monitoring compost quality from both aerated bunkers and windrow compost. This will provide benefits through cost savings and benefits of organic fertilizers.

Leaf Analysis Laboratory supports agronomy division by analyzing plant tissue, soil, compost, mill waste and fertilizer. This laboratory affiliate to International Plant Analytical Ex-change in Wagenighen University in Netherland (external) for laboratory quality monitoring as well as daily quality control as internal monitoring

Fertilizer Recommendation

Fertilizer recommendation is one BLRS service that aims to determine the dosage and type of fertilizer that is optimal for oil palm plantations, good for immature plants (TBM) and mature plants (TM).

By the accurate of dosage and type of fertilizers, the growth and crop productions could reach more optimum level and profitable for longer terms. Beside determining the dosage and types of fertilizers, BLRS also provide additional services of training to the customers; methodology of sampling, field inspection and a complete fertilizer report. Here are the service rates for providing the fertilization recommendations.

Total Area (Ha) Price (Rp / Ha)
Creating new LSU 6,000
0-3000 16,500
3001-5000 16,000

All visit costs such as accommodation, transport and meals are borne by the customer

An example of cost calculation for the garden area of ??6,500 ha: 3,000 ha x Rp. 16.500 2.000 1.500 Rp.16.000 ha ha x x Rp. 14,000 = Rp. 10 2.500.000, - (without creating new LSU).

Crop Protection

Activity of Crop Protection focus on preventing loss of crop yields through the development of an effective integrated pest and disease management (IPM: Integrated pest and disease management) based on monitoring the potential outbreaks of pests and diseases, identification of pests and new pathogens, as well as the development of an effective biotechnology-based controlling methods.

BLRS continue to achieve significant progress in the development of plant material that is more resistance to Ganoderma. We also conduct intensive efforts to optimize the practice of replanting oil palm and rubber in order to prevent loss of crop yields during the first years after planting.

One of the integrated controls that have been implemented in Lonsum's plantations is the use of beneficial microorganism agents (Biofungicides). The selection of biological agents to control Ganoderma infections has been carried out by Sumatra Bioscience (SumBio) i.e Trichoderma SBJ8 derived from oil palm in Lonsum plantation, North Sumatra which has been tested in the laboratory, nursery and field. The result showed that the tested-isolates were able to control Ganoderma. Trichoderma is recommended to be applied in nursery planting, planting hole, and sanitazion hole. The price is Rp. 18,500 /kg
