Studies regarding the phenologic evolution of maize under the influence of climate conditions at the Didactic Station in Timisoara, Romania

Abstract

In 2013 and 2014, years with medium climate favourability for maize, we monitored the growth and development of three maize hybrids from different precocity groups FAO 280, FAO 490, and FAO 550. Plant growth and development was influenced by precipitations and temperature. A rainfall regime rich in ripening phenol-phases determined their prolongation. The vegetation period (sprouting – full ripening) was longer in all three hybrids in 2014. The maize hybrid from group FAO 490 was closer in length of vegetation period to that of the hybrid from group 280 than to that from the group 550. Measurements regarding the phenological evolution were made primarily to avoid an overlapping with climate conditions given that both temperature and precipitations have more or less significant effects on yield depending on maize pheno-phase.
