Treatment
1 is the uninoculated control.
Treatments include peat-based, liquid, oily, with and
without fungicide products. Pre and B10 treatments belong
to BIAGRO inoculants.
Pre= preinoculated seed with Nodulest 10 inoculant,
Single Dose, and with more than 75 days of storage,
bought in Semillera Moreno SRL. America - Buenos Aires
Province.
B10= Nodulest 10 inoculant, Double Dose, and with Biagro
Fungicide for soybean (Thiram 16%, oily suspension).
Until V3 (14 emergency days) the rains were scarce;
therefore, data was subsequently obtained in V7 (34
days) when rains had already been registered (though
below the necessary amount for the region).
In R5, nodules were counted on the main root (Rppal),
on secondary roots (Rsec) and the sum of Rppal + Rsec
= Total.
The
chart comparing grain yields shows different colour
bars that belong to the different groups of products
identified with letters, whose results (within the group)
do not differ statistically. Each bar represents the
minimum value of the group. Different colors indicate
different yields. The treatments with Nodulest 10 inoculant
plus fungicide and preinoculated seed with a single
dose of Nodulest 10 inoculant (B10 and Pre) belong to
the group that obtained the highest grain yields and
contribution of atmospheric nitrogen from the Symbiotic
Nitrogen Fixation.
