** The rates given for Fertilizer borate and Solubor ar~ based on elemental
Boron and not manufactured product.
Rates given refer to the rate per acre in an 8 11 band. The total rate ot
Boron delivered per planted acre would be 1/3 of that reported in table 1.
*** A majority of injury in on~ treatment was suspected to be due to competition
of a hedgerow that was near one plot of this treatment
Discussion: Expt. I
Treatments worthy of note from the standpoint of weed control and lack of
beet injury are as follows: 4 Ibs. Vegadex; 13.8 and 27.8 Ibs. Boron in
Fertilizer Borate; 4 Ibs. Eptam pre-plant and 4 and 6 Ibs. Stauffer 2061 pr~plant.
