Pueraria javanica (PJ) Cover Crop Seeds

Pueraria javanica (PJ) Cover Crop SeedsPueraria javanica (PJ), also called tropical kudzu (Pueraria phaseoloides), is a fast growing tropical legume cover crop for rubber, coconut and oil palm. It fixes up to 250 kg N ha year (85 to 93% drawn from the air), forms rapid ground cover, and cut runoff 88% and soil loss 98% versus bare soil in replanted rubber. Chemiseed Sdn. Bhd. supplies PJ seed, tested to ISTA and AOSA methods, for Malaysia, Indonesia and export. PLANT CHARACTER Fast

PLANT CHARACTER

Fast-growing, trailing to twining annual/short-lived perennial legume. Forms a dense, self-regenerating ground cover under plantation canopies. Deep root system contributes to subsoil moisture access and nutrient cycling.

USES
Nitrogen fixation, erosion control, soil moisture retention, potassium cycling, weed suppression, and cover crop for replanting phases. In immature rubber, field research confirms Pueraria javanica can fix up to 250 kg of nitrogen per hectare per year, with 85-93% of that nitrogen drawn directly from the atmosphere at full ground cover. In replanted rubber, a legume cover including Pueraria reduced runoff by 88% and soil loss by 98% versus bare soil (Perron et al., 2024). For optimal germination results, pair with Seed Activator during planting. See also: PJ vs MB Comparison.

GROWTH HABIT
Vigorous establishment under full sun and moderate shade. Produces 14,347 kg of fresh biomass per hectare at 150 days in Philippine plantation trials. Biomass decomposes at 95.66% within 3 months, releasing 3.572% N, 0.245% P, and 0.809% K directly into the root zone.

COCONUT & MULTI-CROP USE
Established as a basin legume in coconut, Pueraria javanica contributes 28.45 kg of biomass and 196.2 g of nitrogen per basin, and can substitute up to 30% of nitrogen fertiliser requirements (Indian Coconut Journal, 2022).
