SCIENTIFIC CONSULTATION: ENHANCING THE CAPACITY TO CONTROL CADMIUM AND AURAMIN O IN DURIAN CULTIVATION IN VIETNAM(14/05/2026)

On April 24, 2026, WASI and SOFRI co-organized a scientific consultation workshop. The meeting focused on improving a research proposal on controlling Cadmium and Auramine O in durian farming in Vietnam. This was the second consultation session within a broader project led by WASI. The project aims to strengthen capacity and promote sustainable innovation in the Central Highlands fruit sector. The event took place at SOFRI in Long Dinh commune,…

Summary article: Soil acidification and nutrient imbalance under intensive Black pepper plantations in the Central Highlands of Vietnam Nguyen Van Long, Pepper Research and Development Center, Western Highland Agriculture and Forestry Science Institute. Black pepper is one of Vietnam’s key export crops, largely concentrated in the Central Highlands. In recent years, however, productivity and sustainability of black pepper production systems have been increasingly threatened by soil degradation and rising pressure…

INVESTIGATE THE EFFECTS OF DIFFERENT LEVELS OF RIPENESS OF BLACK PEPPER BERRIES ON QUALITY IN THE CENTRAL HIGHLANDS(11/12/2025)

Abstract PhD. Nguyen Van Long Determining the harvest stage is one of important factors that directly affect the yield and quality of black pepper. The experiment investigated the effect of harvesting ripe levels of pepper fruits on quality in Gia Lai and Dak Lak provinces, including 5 treatments: CT1 (the number of ripe fruits/spike > 75%), CT2 (the number of ripe fruits/spike > 50%), CT3 (the number of ripe fruits/spike…

The short-term effect of coffee husk biochar application in acidic soils on soil properties, root mycorrhization, pest, and disease management and yields in Robusta coffee and black pepper plantations in Gia Lai province, Vietnam(09/12/2025)

Abstract Vietnam is the world’s leading exporter of Robusta coffee and black pepper. However, the widespread use of intensive cultivation practices has contributed to progressive soil acidification and an increasing incidence of soilborne diseases, threatening the long-term sustainability of these high-value crops. This study evaluated the short-term effects of applying coffee husk-derived biochar (2.5 t ha−1) on soil quality, pathogen suppression, and crop performance in acidic soils of coffee and…

Soil properties influence the prevalence of soilborne pathogens in Robusta coffee and black pepper systems in Vietnam’s Central Highlands(04/12/2025)

PhD. Nguyen Van Long Abstract Monoculture and intensive fertiliser use in the cultivation of Robusta coffee (Coffea canephora var. Robusta) and black pepper (Piper nigrum L.) have led to soil degradation and increased disease pressure in Vietnam’s Central Highlands. To identify key factors driving soilborne diseases and threatening sustainable production, a soil and root survey was conducted across three provinces: Gia Lai, Dak Lak, and Dak Nong. Soils were characterised by high…

Scientific consulation “enhencing the control capacity for Cadmium and Auramine O in durien cultivation and production in Vietnam”(09/10/2025)

On September 30th, 2025, the Western Highlands Agriculture and Forestry Science Institute (WASI) organized a scientific consultation meeting to develop the research proposal titled “Enhancing the ControlCapacity for Cadmium and Auramine O in Durian Cultivation and production in Vietnam”. The event was part of a larger project on controlling these two substances to promote the sustainable development of the fruit and vegetable innovation network in the Western Highlands, led by…

EFFECT OF ARACHIS PINTOI INTERCROPPED WITH BLACK PEPPER PLANTATIONS IN THE CENTRAL HIGHLANDS(10/09/2025)

Nguyen Van Long*, Vo Chi Cuong, Nguyen Do, Dinh Thi Ngoc Hanh Pepper Research and Development Center, 322 Truong Chinh, Hoi Phu Gia Lai. *Email: vanlongpleiku@gmail.com ; ĐT: 0935 493 127   ABSTRACT Pinto peanut (Arachis pintoi) is a versatile legume that helps protect soil, improve its physicochemical properties, and, significantly, fix nitrogen. The study aimed to identify the biomass, nutrient content, and the effects of Arachis pintoi mulch on soil…

Evaluating the Seed Propagation Potential of Selected Vietnamese Black Pepper Varieties (Piper nigrum)(06/06/2023)

ABSTRACT Sexual hybridation is primary method for black pepper breeding in order to select good varieties with higher productivity, yield, quality as well as resistance to disease and environmental risks. Research showed that white pepper seeds germinated after 13-27 days after incubation, most of seeds were germinated 15-23 days after incubation with 56,1-86,9% of seeds germinated. The three-month old seedlings of  H-DP6 and  H-L1 showed better growth with good plants…
