Boron Nutrition of Almonds

IPNI-1992-USA-CA13

In 1994 a study was initiated to determine the effect of boron (B) nutrition on flowering, fruit set, and yield of almond following a similar (and very successful) study with pistachio. Spraying B at a rate of 1-2 lb Solubor/100 gal on B deficient almond trees increased fruit set by over 20% and yields by 15 lb/tree or 1200-1500 lb/A or 900-1125 lbs of kernels/A in 1995. Read more

Interpretive Summary

Boron Nutrition of Nut Crops, 1998 This project studies the benefits of foliar B sprays applied at different rates and time on yield and quality of almond and walnut nut crops. The project was initiated in 1994 and completed at the end of the 1998 growing season. Almond research evaluated the effect of B nutrition on flowering, fruit set, and yield following a similar (and very successful) study with pistachio.

Boron nutrition of nut crops, 1997 In 1994 a study was initiated to determine the effect of boron (B) nutrition on flowering, fruit set, and yield of almond following a similar (and very successful) study with pistachio. Spraying B at a rate of 1-2 lb Solubor/100 gal on B deficient almond trees significantly increased fruit set and yields in 1995 and 1996.

Boron Nutrition of Almonds and Prunes, 1996 In 1994 a study was initiated to determine the effect of boron (B) nutrition on flowering, fruit set, and yield of almond following a similar (and very successful) study with pistachio. Spraying B at a rate of 1-2 lb Solubor/100 gal on B deficient almond trees increased fruit set by over 20% and yields by 15 lb/tree or 1200-1500 lb/A or 900-1125 lbs of kernels/A in 1995.
