Managing Alternate Bearing

2016 Research

In this research, we have modeled the relationships between leaf nutrient concentrations and the yields of avocado trees with the aim of developing decision support tools for improved fertilization and nutrient management to increase avocado fruit yields.

2011 Research

The goal of this research is to increase grower profitability by developing plant growth regulator (PGR) strategies to mitigate alternate bearing.

 

2010 Research

The goal of this research is to increase grower profitability by developing PGR strategies to mitigate alternate bearing. The strategies being tested are designed (1) to overcome apical dominance to stimulate summer and fall shoot growth during the on-crop year to increase the number of nodes that can bear floral shoots the following spring and (2) to increase spring bud break to increase the floral intensity of the return bloom and increase yield (putative off-crop).

2008 Research

Project overview
In alternate bearing 'Hass' avocado orchards, yield is reduced below the potential of the orchard and grower income is significantly reduced during off-crop years. The goal of this research is to increase grower profitability by clarifying whether treatments that increase summer and/or fall shoot growth can be used to increase floral intensity the following spring and, thus, yield by establishing which buds (apical or axillary), if any, on which shoot flush (spring, summer or fall) of on-crop trees remain floral

2007 Research

In alternate bearing 'Hass' avocado orchards, yield is reduced below the potential of the orchard and grower income is significantly reduced during off-crop years. The goal of this research is to increase grower profitability by clarifying whether treatments that increase summer and/or fall shoot growth can be used to increase floral intensity the following spring and, thus, yield by establishing which buds (apical or axillary), if any, on which shoot flush (spring, summer or fall) of on-crop trees remain floral and for how long.
