Efficient microorganisms in the production of purple corn (Zea mays L)

Abstract

The study analyzes the effect of three levels of efficient microorganisms (EM) on the yield of grain and cob of purple corn (Zea mays L.), which was carried out at the INIA Donoso agrarian experimental station, in Huaral, Lima, Peru in the agricultural period 2019-2020. Three treatments were applied: T1= 01 Lt. ME, T2= 03 Lt. ME, T3= 06 Lt. ME and one control 00 Lt. ME, with four replicates in a completely randomized block experimental design (DBCA). The results conclude that the doses of EM applied to the purple corn variety PMV 581, have a significant effect (p-value < 0.05) on the grain yield with values ​​for the control of 3.54 ± 0.77 MT/Ha, with increases in the ( T1) at 5.05 ± 0.54 TM/Ha, in (T2), with 5.64 ± 0.33 TM/Ha and (T3) with 6.53 ± 0.77 TM/Ha. In the results of production of cob it is similar, achieving results for the (control) 1.09± 0.24 TM/Ha, increasing in (T1) 1.26± 0.27 TM/Ha, in (T2) 1.45± 0.28 TM/Ha and the (T3) with 1.74± 0.30 MT/Ha. and it is concluded that there is an effect on the yield of grain and purple corn cob, resulting in (T3)=06Lt EM, achieving a better average yield in grains and purple corn cob, compared to the control treatment.
