Cím:	Plant density impact on grain yield of maize (Zea mays L.) hybrids on chernozem soil of the Eastern Hungary / Pepó Péter, Murányi Eszter

Megjegyzések:	The plant density response of 12 maize hybrids was tested in a favourable year (2013) under optimum agrotechnical conditions on chernozem soil by applying plant densities of 50, 70 and 90 thousand plants ha-1. Due to the favourable ecological and agrotechnical conditions. Yields varied between 11400 and 16300 kg ha-1 depending upon the hybrid and the plant density. From among the hybrids, 5 and 7 produced the maximum yield at 70 and 90 thousand plants ha-1, respectively however the yield increment was not significant between 70 thousand plants ha-1 and 90 thousand plants ha-1. No relationship was found between the season length and the optimum plant density of hybrids. Those hybrids were the most favourable, which gave a stable high yield at different plant densities that is their optimum plant density range was wide (P 9175, P 9494, SY Afinity). Hybrids with a small optimum plant density range (P 9578, DKC 4490, PR 37N01) gave the highest yield at a specific plant density (70 thousand plants ha-1 or 90 thousand plants ha-1). A special complex coordinate system was developed for evaluation for the plant density response of maize genotypes specific ecological and agrotechnical conditions can be evaluated jointly.
