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.

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…
