ABSTRACT:

Experiments were conducted in 1987 and 1988 to study the response of Amaranthus cruentus L. to flooded soils at Ekpoma, situated in the Niger Delta Region of Nigeria. The objective of this study was to examine the effect of flooding on yield of A cruentus. The study revealed that the negative response of the vegetable crop to flooding was significant (P<0.05). The genernl effects were low dry weight yields, wilting and yellowing of leaves leading to senescence and eventual death of the plants. At week eight. control plants had significant (P<0.05) higher dry matter yields of 4 g/plant thn.i 0.3 g/plant dry matter recorded for plants inflooded conditions. The flooding effects resulted in 93.4% yield decrease. Similarly; leaf area of flooded plants was 4.4 cm;,/ plant while that of control plants was 12.8 cm2/plant. Thus, a 65.6% reduction was obtained due to flooding effects. The response of the plants to flooding confirmed that yield decrease significantly (P<0.05) as the flooding persisted. This thorough understanding of how flooding affect Amaranthus cruentus would aid in the development of strategies for the cultivation and availability of the leafy vegetable crop in the Niger Delta Region for enhanced livelihoods. Further studies examining flooding effects on other leafyvegetable crops are likely to increase our understanding of the response of valuable vegetables to water stress.
