Fertilizer Trial on Bush Snap Beans

Paul H. Everett
Assistant Soils Chemist


A factorial experiment was conducted at the South Florida Field Laboratory to
measure the yield response of bush beans to 3 levels of fertilizers and 3 levels of
a complete minor element mixture. Field plots consisted of paired rows 20' long and
2' apart on beds spaced 3' apart. Thus each plot was equivalent to 40 linear feet.
The plots were arranged in randomized blocks with 4 replications.

The plot area was located on virgin Immokalee fine-sand with an initial pH of
4.4. In July 1963 the area received a uniform application of lime equivalent to 2
tons of dolomite plus 2 tons of high-calcium limestone per acre. At planting time
the soil pH in the 4 replications ranged from 5.8 to 6.0.

On October 1, 1963, the beds were prepared and the various fertilizer and min-
or element (m.e.) treatments were applied as shown below in the cross section dia-
gram.

__-----___ ''--------> ---:
The total amounts of fertilizer and m.e. shown in Table 1 were applied in a single
application 2 days prior to planting.

On October 3, 1963, bean seeds (var. Harvester) were planted, 10 per linear
feet 1 1/2" deep. Final plant stand averaged 8 plants per linear foot. Rainfall
was light with only 2.5" occurring during the crop season. However, the soil mois-
ture was maintained relatively high by seep-irrigation.

The plots were sprayed 3 times with parathion and 3 times with zineb plus par-
athion. No serious disease or insect problem was encountered.

The beans were harvested on Dec. 2, 1963. This was the only harvest made and
although the beans were picked by hand an effort was made to simulate mechanical
harvesting.

The yield data on a per acre basis are shown in Table 1. At the 5% level the
yield from plants receiving the 2000/lbs./A rate was significantly better than the
yield from the 1000 or 1500 lbs./A rates. The 1500 lbs./A rate barely lacked sig-
nificance over the 1000 Ibs./A rate. At the 1% level the yield from the 2000 Ibsi/A
rate was significantly better than the yield from the 1000 lbs./A rate but not sig-
nificantly better than the yield from the 1500 lbs./A rate. There were no signifi-
cant differences in yield due to the added minor elements.
