Febles H., Reyes J. Influence of different soil moisture contents on flowering, yield and fruit quality of Valencia orange adult trees.
Agricultural Science Institute, Havana 1985, Cuba
The influence of different moisture contents in the soil on the flowering, yield and fruit quality in orange adult trees of the Valencia variety, in a red Ferrallitic soil at Citrus Experiment Station of Güira de Melena in Havana province was studied.It was found that in Valencia orange variety, the yield is enhanced when the plant is subjected to water stress in the before flowering stage.
The optimal variant economy was obtained by performing the first irrigation when the soil humity reaches in a Red Ferrallitic the 65% of field capacity in the first 30 centimetre depth from the third decade of December to the second decade of January, ensuring adequate stress to induce plant flowering.
After the first irrigation, should be maintained soil moisture at 80% of field capacity during the period of drought. The largest consumption of water is reached between the months of March to July that coincide with the critical stage of the crop: flowering and second stage of fruit development. From November to mid January is observed the lowest water consume that coincides with the period of fruit ripening.
