Cím:Effect of plant density and row spacing on maize (Zea mays L.) grain yield in different crop year / Eszter Murányi
Dátum:2015
ISSN:2064-7816 2064-9479
Megjegyzések:Nowadays the aim of crop production is to realize the highest possible yield per production area unitby the highest possible crop safety. One of the possible ways for this is to increase of plant density or to decreaserow spacing. Therefore, the plant number per unit area can be increased and the potential yield loss of individualplants is compensated by the higher plant density.The development of yield amounts of eight different genotypes was investigated in a small-plot field experimentwith four replications on a calcareous chernozem soil type at the Látókép Research Site of the University ofDebrecen in the crop years 2013 and 2014. Row distances of 45 and 76 cm, just as plant densities of 50 000, 70000 and 90 000 plants per ha were set.Significant differences were found between the yield amounts of the studied hybrids in both studied crop years,while the effect of plant density on yield amount showed different results. In the crop year of 2013 the hybridsresulted high yields in the treatment with a row distance of 45 cm and plant density of 90 000 plants per ha,however, in 2014 significant yield decrease was found in comparison with the previous year, that can be attributedto the weather conditions in the months April-May and June.Optimal plant densities of hybrids, just as the corresponding expectable yield amounts were determined withquadratic equations. Optimal plant densities of the hybrids were different in the two studied crop years: in 2013,regarding the treatments set with the row distance of 45 cm, increasing plant densities resulted in higher yields,while in 2014, the yield showed decreasing tendency parallel to the increasing plant densities, that is confirmedby the fact that plant densities of 50 000 and 65 000 plants ha-1 proved to be more favourable. Regarding thetreatments with a row distance of 76 cm, hybrids obtained their yield maximums by 80 327 plants ha-1 in 2013,while in the vegetation of 2014, by higher plant density (85 845 plants ha-1).

Cím:Plant density impact on grain yield of maize (Zea mays L.) hybrids on chernozem soil of the Eastern Hungary / Pepó Péter, Murányi Eszter
Dátum:2014
ISSN:2064-7816
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.
