Tomato seedlings inoculated with actinobacteria and composted with biomass of legumes

Abstract

The consumption of vegetables has increased due to greater awareness of the world population
for a healthy diet. One of agricultural alternatives to promote nutrition and plant improvement
to the seedlings, soil fertility replenishment and increase crop productivity is the use of
green manures and beneficial microorganisms. This study evaluated the effect of incorporation
of green manure (crotalaria, pigeon pea, velvet bean and jack bean) combined or not with isolates
of actinomycetes (AC-39, AC-50 and AC-92) on the growth and nutrition of seedlings tomato.
The isolated AC-50 stood out compared to other isolates and green manures, promoting
increase of up to 256.5% the N content of tomato seedlings. In terms of P, the best results were
recorded with the interaction between the pigeon and the isolated AC-50. The incorporation of
the combination in jack bean with the AC-50 alone, resulted in increase in K levels in tomato
seedlings.
