Abstract
Abstract ‘Bush Blue Lake 283’ beans ( Phaseolus vulgaris L.) were grown with 16 fertilizer treatments at 16 commercial sites in Pennsylvania in 1973-74. No treatment gave significantly higher combined yield at one harvest than the NP treatment (28 kg/ha of each). This treatment resulted in increases of 27% in vine weight and 9% in yield while leaf concentration of Ca and Mg were enhanced by 19% and 36% respectively and K concentration was decreased by 17%. Added K which further increased vine weight but not yield, depressed Mg leaf concentration but this was more than compensated for by the NP enhancement. Although added Mg did not affect growth responses, it increased Mg leaf concentration, decreased Mn concentration and tended to decrease P and Ca concentration but did not lower K leaf concentration. When both K and Mg were added, Mg leaf concentration was no higher. Diammonium phosphate had no injurious effects.
