Cím:	Water use efficiency of sorghum and maize treated with PENTAKEEP-V / Zsembeli József, Kovács Györgyi, Murányi Attila, Tanaka Tohru
Dátum:	2009
Megjegyzések:	In weighable lysimeters the effect of Pentakeep-V on the water balance of sorghum and maize is tested combined with an irrigation experiment. Pentakeep-V is a special foliar fertilizer containing the precursor of chlorophyll synthesis, namely 5-aminolevulin acid (5-ALA). As the effect of PV on water balance of the soil is not known, therefore an experiment was set up in 2007 to determine the evapotranspiration of three sorghum hybrids and continued in 2008 with a comparison test of maize and sorghum. The considerable effect of both treatments could be quantified by means of the precision weighing lysimeter devices. We found differences in the amount of evapotranspiration and increase in yield and sugar content due to the treatments. By means of different indexes we calculated, water use efficiencies were compared. As we found a new probable effect of Pentakeep-V, we think it accelerates ripening, further studies are needed to get more detailed information in this respect
