F. Burlocarbonell et al., EFFECTS OF IRRIGATION WATER-QUALITY ON LOQUAT PLANT NUTRITION - SENSITIVITY OF LOQUAT PLANT TO SALINITY, Journal of plant nutrition, 20(1), 1997, pp. 119-130
An investigation was conducted to study the possible use of municipal
wastewater for watering loquat plants, and to determine the effects of
this water on nutrient status of two-year-old loquat plants (Eriobotr
iae japonica L.) during two complete vegetative cycles. The plants, gr
afted on franco and Anger stocks, were planted on major soils of the a
rea of La Marina Baixa. Plants (grafted on franco stock), irrigated wi
th this wastewater, suffered from foliar necrosis, and all of them die
d at the end of the experiment, whereas only 12.5% of the plants water
ed with municipal drinking water died at the same period of time. The
Anger stock proved to be much more resistant to salinity than the fran
co stock. Therefore, medium quality waters (wastewater and saline wate
r) can be used for the irrigation of loquat trees grafted on Anger sto
ck, without causing damages on plant nutrition.
