abstract:
Microplot experiments with triticale Woltario variety were conducted in the years 1999-2002. Different levels of fertilization: 160, 260 and 360 kg NPK h-1 and different plant densities: 100, 200 and 300 plants m-2 were taken into consideration. During vegetation period SPAD index was determined. SPAD values taken up to flowering stage at density of 200 plants m-2 increased under fertilization at 260 and 360 kg NPK ha-1. SPAD values for Woltario variety seem to be optimal at shooting stage _ 664 and at heading stage _ 681.
