Drought as a Factor for Cob Yield of Maize (Zea mays L.)

In this investigation the yield of dry maize cobs, cultivated underdrought conditions has been analysed. Depending on climate conditions asduring the year, as well depending on genetic characteristics of the maizehybrids, the cob yield is variable.In drought conditions, the lowest cob yield for three years ofexperiment was gained from Stira (960kg/ha), while the highest from ZP360(1460kg/ha). In irrigated conditions, the lowest yield was found in Colombahybrid (1570kg/hec), and the highest in Constanza (2650kg/ha)

The relation Seed - Cob at the Maize Hybrids (Zea mays L.) Cultivated Under Drought Conditions

In this investigations have been measured relation between the seedyield and cob yield, at the maize hybrids cultivated under drought conditions.From the results, we can note a different relation rates between percentage ofthe seed and cob each year, mostly depending on climate conditions during theyear, as well depending on genetic characteristics of the maize hybrids

Influence of the Water Deficit on the Yield Elements of Maze

In the period of three years, there have been established investigations, about influence of water deficit on the yield elements of maize. The research has been performed in eight hybrids of maize, which belong to four FAO groups. From the results, we can note increasing of the values of structure elements of yield, in all investigated maize hybrids. Under drought influence, the number of ear per plant was decreasing for 27,6 %, ears length for 17,5 %, diameter of ear for 20,2 %, seed length for 23,2 %, and number of rows per ear for 12,6 %
