The effect of different condensed phosphates on the yield of Lolium multiflorum and their effect on different interrelations
Keywords:salts of NH4, fertilizers, Lolium multiflorum
The condensed phosphates such as ammonium pyrophosphate, potassium, metaphosphate, ammonium polyphosphates are among the newest achievements in the domain of fertilizers (5, 6). Results of various experiments have shown that these fertilizers increase the yield in wheat, barley, maise, potato, sugar beat, bean and others (2, 3, 5). However, experiments in this field are few (3). In Lolium multiflorum the reactions of these forms of phosphorus were not illustrated in many cases, because the experiments had been carried out with salts of NH4, K and Ca, where the effect was combined. The objective of this report is to present results of a series of greenhouse pot experiments.
