Abstract

Effective microorganisms (EM) have an effect on soil, seed and plant metabolism. Its effect is more effective in soils rich in nutrients and organic matter than in poor ones. Soil received limestone and Fosmag (P, K, Ca, Mg, S, Cu, B and Zn). The treatments were in 3 x 4m-plots in the midst of a bean plantation. Treatments were: 1) Diatom (petrified, grounded algae); 2) EM to seeds; 3) Biosol; 4) Cofermol (Co+Fe+Mo); 5) EM + diatom; 6) EM + MB-4 (rock meal); 7) Control, 8) MB-4. After the emergence of bean plants in 3 and 5 weeks, EM foliar application (0,1%) and Mo (0,04%) were made. Being a very rainy season, many farmers lost their yield in spite of frequent pesticide applications due to fungi diseases like anthracnose. Our beans were attacked by anthracnose and 1,5% grains were mottled. The best treatments were: (2) EM application to seeds (1620 g/plot); (6) EM + MB-4 with 1783 g/plot and (7) the test plot only with foliar EM + Mo application having 1925 g/plot. Experiments show that Mo increases the number of pods per plant and the number of grains per pod whilst EM increases grain weight (1000 grains = 300g to 380g and 1 liter from 844 to 920 g). This means that EM increases grain quality because proteins are heavier than amide.
