Determination of Adverse Effect of Water Stress on Corn (Zea maize L.) according to the Stages of Growth
A field experiment was carried out for the purpose of studying the effect of water stress, according to stages of growth of maize where the experiment was carried out at the Agra Technology Research Station, University Malaysia Perlis Padang Besar, Perlis, Malaysia in March 2014 to June 2014 to investigate the influence of studying the effect of irrigation dates on maize crop for the purpose of studying the effect of irrigation dates on maize crop. The results of the research showed the effect of water stress at all stages of plant growth. The results showed that the most sensitive phase of water stress is the flowering phase; also the results showed that water stress had a negative impact on all parameters of the experiment. The highest rate of all study parameters was recorded at the first date (irrigated every seven days) and a significant difference from the second date. While the lowest rate of all qualities was recorded in the second appointment (irrigated every 14 days), no significant difference was recorded between the first date (irrigated every 7 days) when compared with the control treatments where the crop was irrigated whenever the plant needed water. The results showed that irrigating every 7 days of the autumn season is most appropriate and no significant difference was recorded when comparing the control treatment. The results elucidate that irrigated every 14 days gave the lowest rate of all traits but it is used in case of severe water scarcity.
