Cím:	Agrometeorological and agrotechnical risks in maize (Zea mays L.) production / Pepó Péter, Tótin Ákos

Megjegyzések:	Maize has high productivity and produces hudge vegetative and generative phytomass, but maize is very sensitive to agroecological (mainly to climatic, partly to pedological conditions) and agrotechnical circumstances. In Hungary maize is grown on 1,1-1,2 million hectars, the national average yields vary between 4-7 t ha-1 depending on the year and the intensity of production technology. The crop rotation, fertilization and plant density on the yields of maize were investigated in dry and wet cropyears in a long-term experiments on chernozem soil. The water-supplies were rainfed and irrigated. In dry cropyear the yield-surpluses of irrigation were 2.8-4.2t ha-1, in the cropyear characterized by average-goodwater supply the yield increasements of irrigation varied between 0.7-2.1 t ha-1, respectively. The yield-increasements of irrigation were mainly modified by crop rotation and fertilization. The optimum plant density of maize was different in the rainfed and irrigated crop technology on chernozem soil.The maximum LAI values of maize (4.0-4.8 m2m-2) were in middle July and the SPAD values were on high level (56-59) between early July and middle August in maize production.

Cím:	Effect of grain maize forecrop and fertilization on values of leaf area index and on the yield of winter wheat / Szilágyi Gergely, Murányi Eszter, Tótin Ákos, Vincze Éva
Dátum:	2015
Megjegyzések:	Our field experiment took place on the test farm of KIT Látókép of University of Debrecen, Applied Economic Sciences, in growing seasons 2012/2013 and 2013/2014. The previous forecrop was grain maize with control, N60+PK and N120+PK fertilizer treatments,with two varieties GK Csillag and Mv Csárdás on chernozem soil, in long-term experiment. According to our scientific results, effect of the cropyear and variety determined the valuesof the leaf area index (LAI) and the yield. In 2013/2014 growing season varieties had muchlarger assimilative surface, which caused increase in leaf area index and in the yield. Bettercropyear increased the natural nutrient utilization capability of GK Csillag and Mv Csárdás. Compared to the previous year, in control treatment we measured 248.0-290 % higher yield and LAI (233-280 %) due to the favourable effect of the crop year. Maximum yield (8.03 tha-1) was measured with N60+PK fertilizer treatment with variety GK Csillag in 2013/2014 cropyear.
