• COCONUT

  MARENA MARENA hybrid coconut is a cross between the Malayan Red Dwarf (MRD) and the Laguna Tall (LAGT) coconut palms. It is a hybrid coconut with large-sized fruits and high yield potential, capable of producing up to 25,000 nuts/ha/year.
  	MARLECA The MARLECA hybrid coconut is a cross between the Malayan Red Dwarf (MRD) and the Niu Leka (NLAD) coconut palms. It is a hybrid coconut with large-sized fruits and a relatively slow growth and height increase, with a yield potential of 25,000 nuts/ha/year.
  CARENI Merupakan kelapa kacukan Cameroon Red Dwarf (CRD) dan Nias Green Dwarf (NGD). Kelapa hibrid untuk minuman segar dengan potensi hasil sebanyak 32,000 biji/ha/tahun.
  	MYLAG The MYLAG hybrid coconut is a cross between the Malayan Yellow Dwarf (MYD) and the Laguna Tall (LAGT) coconut palms. It is a high-yielding hybrid coconut with a yield potential of 25,000 nuts/ha/year.
  MYLECA The MYLECA hybrid coconut is a cross between the Malayan Yellow Dwarf (MYD) and the Niu Leka (NLAD) coconut palms. It is a hybrid coconut with a relatively slow growth and slow height increase, with a yield potential of 23,000 nuts/ha/year.
  	CARECA This is a hybrid coconut variety resulting from a cross between the Cameroon Red Dwarf (CRD) and the Catigan Green Dwarf (CTAD). It is a hybrid coconut developed for fresh drinking, with a high yield potential of up to 32,000 nuts/ha/year.

  VITATO ANGGUN 1 ANGGUN 2 ANGGUN 3 LEMBAYUNG	HIGH-NUTRITION SWEET POTATO VARIETIES Development of sweet potato aims to produce new superior varieties that are high-yielding and high-value, rich in nutrients, and provide economic returns to sweet potato growers and producers, particularly in the food industry.
  SWEET POTATO FERTIGATION TECHNOLOGY The sweet potato fertigation cultivation system can enhance the production of quality sweet potatoes. Fertilization is one of the important components in increasing the yield of sweet potato tubers. Sweet potatoes require balanced plant nutrition at every growth stage. Therefore, a specific fertilizer has been developed by MARDI to enhance the growth and yield of sweet potato tubers.

  	BIOPESTICIDE FOR WHITE GRUB CONTROL IN SWEET POTATO CROPS A formulation based on a combination of plant extracts for the control of white grubs in the field via the drenching/reservoir method.
  METHOD FOR CONTROLLING CURVULARIA LEAF SPOT IN SWEET POTATO CROPS A formulation based on herbal extracts from spices and plants for the control of Curvularia leaf spot disease. The percentage of the disease index (PDI) decreased by 72% after the second spray application.
  	SWEET POTATO POST-HARVEST HANDLING The technology for sweet potato post-harvest handling has been developed covering harvesting index, sanitation, curing, packaging, and storage.
  POST-HARVEST HANDLING OF FRAGRANT TARO The post-harvest handling technology developed in this study takes into account the precise timing of taro corm harvesting, which is crucial for taro to ensure premium quality, high nutrition, and optimal taste. The taro corms must be cured to maintain quality (healing mechanical injuries on the skin, reducing spongy texture/pithiness, maintaining pseudostem freshness, slowing fungal growth) and to extend shelf life.
  	APPLICATION OF PLANT GROWTH REGULATOR (PGR) TO INCREASE SWEET POTATO YIELD PGR application can increase sweet potato yield (2.4 kg/plant using the fertigation system and 1.2 kg/plant using the conventional method) compared to without PGR (1.5 kg/plant using the fertigation system and 0.86 kg/plant using the conventional method).

• GRAINS

  IPM CONTROL METHOD FOR FALL ARMYWORM (FAW) PESTS IN MAIZE CROPS The IPM control method for grain maize involves the installation of pheromone traps and the alternating spraying of three types of pesticides, consisting of biopesticides and chemical pesticides, based on the level of FAW infestation at different plant ages.
  	GRAIN MAIZE PRODUCTION TECHNOLOGY This technology was developed by MARDI to address the issue of the shortage in local grain maize production and the reliance on imported grain maize sources for the production of animal feed. A standard operating procedure (SOP) for grain maize production has been developed, encompassing variety selection, agronomic practices, disease and pest management, and efficient post-harvest handling.

• COFFEE

  MARDI LIBERICA COFFEE CLONES: MKL 8, MKL 9 & MKL 10 Three new Liberica coffee clones were launched in 2023. The potential yield of coffee berries (coffee fruit) is between 17 – 25 tonnes/ha, which is 60% higher than the yield of commercial Liberica coffee clones. The yield of coffee beans (hulled coffee) is between 1.9 – 2.7 tonnes/ha, with a high conversion rate from coffee berries to coffee beans of between 9.9 – 10.8%, which is 25% higher than the yield of commercial Liberica coffee clones.
  	PHYTONUTRIENT AND FATTY ACID RICH GREEN COFFEE OIL Green coffee from MARDI Liberica clones (MKL 5, MKL 6, and MKL 7) treated with 0.25% salt was used as the raw material for the production of green coffee oleoresin oil with a high content of main components: linoleic acid and phytosterols.
  OPTIMUM DRYING TECHNIQUE FOR GREEN COFFEE BEANS (COFFEE BEAN) Coffee beans from selected clones, namely MKL8, MKL9, and MKL10, are harvested at optimum maturity and dried in a mechanical dryer at a temperature of $60^\circ \text{C}$ for 8 hours for every 5 kg of coffee beans.
  	MASS PROPAGATION TECHNOLOGY FOR COFFEE PLANTING MATERIAL A study on the mass propagation of Liberica coffee was carried out using the Liberica coffee orthotropic stem cutting method, which successfully generated a survival rate exceeding 80% and reduced the production period to 8 – 9 months.
