Abstract:

The independent effects of irrigation solution N, P and K concentrations on flowering and fruit set in olive trees (Olea europaea L. cv. Barnea) were studied over two successive seasons in a container experiment. Treatments included eight levels of N ranging from 5 to 202 ppm, seven levels of P from 0.2 to 20 ppm and seven levels of K from 10 to 208 ppm. At low concentrations of each of the minerals, additions led to large increases in their contents in leaves and, as the concentrations became high, relative increases in leaf accumulation were reduced. Availability of both N and P was found to influence flowering intensity in the olive trees while K had only a minor affect. Fruit set was affected by both N and P but not K levels. Total fruit load of olives was a function of combined flowering and fruit set levels. Fruit load increased to a maximum as leaf N increased from 0.8% to 1.77-1.56% and then decreased as leaf N increased to 2.1%-1.8% (2007 and 2008 respectively). The number of olives per tree increased appreciably as leaf P increased from minimum levels and relative increases in fruit load tapered at the highest measured leaf contents. Maximum fruit load was found corresponding to approximately 0.2% P. Fruit load was not influenced by leaf K concentration. The findings indicate that N and P play fundamental roles in processes affecting olive-tree productivity.

The role of macro-nutrients in olive tree flowering and fruit set

The independent effects of irrigation solution N, P and K concentrations on flowering and fruit set in olive trees (Olea europaea L. cv.

Treatments included eight levels of N ranging from 5 to 202 ppm, seven levels of P from 0.2 to 20 ppm and seven levels of K from 10 to 208 ppm. At low concentrations of each of the minerals, additions led to large increases in their contents in leaves and, as the concentrations became high, relative increases in leaf accumulation were reduced. Availability of both N and P was found to influence flowering intensity in the olive trees while K had only a minor affect. Fruit set was affected by both N and P but not K levels. Total fruit load of olives was a function of combined flowering and fruit set levels. Fruit load increased to a maximum as leaf N increased from 0.8% to 1.77-1.56% and then decreased as leaf N increased to 2.1%-1.8% (2007 and 2008 respectively). The number of olives per tree increased appreciably as leaf P increased from minimum levels and relative increases in fruit load tapered at the highest measured leaf contents. Maximum fruit load was found corresponding to approximately 0.2% P. Fruit load was not influenced by leaf K concentration. The findings indicate that N and P play fundamental roles in processes affecting olive-tree productivity.
