Rp. Beckett et al., EFFECT OF SEAWEED CONCENTRATE ON YIELD OF NUTRIENT-STRESSED TEPARY BEAN (PHASEOLUS-ACUTIFOLIUS GRAY), Journal of applied phycology, 6(4), 1994, pp. 429-430
The effect of the seaweed concentrate 'Kelpak' on the yield of the tep
ary bean (Phaseolus acutifolius L.) grown under conditions of varying
nutrient supply was investigated. Kelpak significantly increased the y
ield of plants growing at all concentrations of nutrient supply by inc
reasing bean weight rather than bean number. Kelpak also tended to inc
rease the N concentration of the beans. The results suggest that Kelpa
k did not act simply as a fertilizer, but as some kind of biostimulant
.
