“…However, due to its perenniality and pervasiveness, kudzu was later classified by the USDA as an invasive weed species in the 1970s (Everest et al 1999). Historically recognized as an exceptional forage legume in the tropical Caribbean island region (Vicente-Chandler et al 1953), kudzu was well-known for its adaptability and summer persistency. However, as a common trait for vinetype plants, the easy-to-propagate feature and pronounced vigour of kudzu also make it one of the most invasive plant species that could easily encroach into existing pasture ecosystems, preventing other predominate forage species from receiving adequate solar radiation and soil nutrients to survive.…”

Early and late season kudzu leaves were collected to analyse dry matter (DM), crude protein (CP), acid detergent fibre (ADF), and neutral detergent fibre (NDF) in situ rumen disappearance to assess kudzu quality. Four studies were conducted during different growing periods [2 repeated early season (ES); 2 repeated late season (LS)] to determine age variability effects. Kudzu was incubated in the rumen between 0.25 and 72 h to determine total rumen degradation (%) and the rate of disappearance (% h −1 ). Data were analysed as a randomized complete block design (RCBD) with repeated measures. Regression analysis was used to determine the degradation rate. Overall season effects (across incubation times) for dry matter disappearance (DMD) were significantly different (P < .0001). There were also significant season by incubation time interactions for DMD. Rumen degradation rate was determined to be 2.41% h −1 across both seasons, with no significant seasonal difference (P = .3396). Results from this study are indicative that ES kudzu is more degradable than LS. Although there are significant seasonal effects on kudzu DMD during certain incubation times, DMD overall for ES and LS is still indicative of high rumen degradability.

“…Phosphorus applications did not affect the content of this nutrient in any of the forages. Vicente, Caro, and Figarella (8) found that kudzu-molasses grass pastures growing on a shallow Múcara soil in the Mountain Region did not respond to phosphorus applications. On the other hand, these investigators found that the early growth rate of tropical kudzu growing alone on an acid soil of the Mountain Region was increased by fertilization with phosphorus (7).…”

A tropical kudzu-molasses grass-Guinea grass pasture mixture growing on a deep, red, acid soil in the Mountain Region of Puerto Rico yielded an average of 12,938 pounds of dry forage per acre yearly with a crude-protein content averaging 8.5 percent, a calcium content of 0.56, and a phosphorus content of 0.26 percent. Liming increased the yield and protein content of tropical kudzu, but did not appreciably affect its calcium or phosphorus content. Liming did not affect the yield, or the protein, calcium, or phosphorus contents of the grasses. Applications of phosphorus had no apparent effect on the yield, or the protein or calcium contents of the forages. The application of 45 pounds of phosphorus per acre yearly, however, increased the phosphorus content of composite samples of the grasses over all yield periods, but not that of tropical kudzu. The results of this experiment suggest the desirability of making light applications of lime and phosphorus to kudzu-grass pastures growing on red, acid soils in the Mountain Region of Puerto Rico.
