LOPEZ-ORTEGA, María Guadalupe et al. Performance and seed quality of ‘pearl millet’ with the use of mycorrhizae Glomus intraradices and chemical fertilizers. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.7, pp.1514-1523.  Epub 30-Set-2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i7.1677.

The objective of this research was to determine the effect of mycorrhizae, chemical fertilization and its combination on foliar area, morphological composition, production and seed quality of pearl millet (Pennisetum glaucum Br.). The evaluation was carried out in spring-summer 2013 in the San Luis Experimental Field of INIFAP, INIFAP and Azo-Fer mycorrhizae were used, as well as 120-60-00 and combination of mycorrhizae with 60-30-00 and a control (without any fertilizer). The variables evaluated were plant height, leaf area index, morphological composition, seed production, weight of one thousand seeds, hectoliter weight, purity, moisture content, number of seeds per kg and efficiency in water use. A completely randomized experimental design was used (Tukey, 0.05). No differences were observed (p> 0.05) in the index of plant height, leaf area, purity, humidity, hectoliter weight and weight of a thousand seeds. Seed production was similar (p> 0.05, kg ha-1) with the use of biofertilizers and fertilizers (mycorrhiza INIFAP= 2 221, mycorrhiza INIFAP + 60-30-00= 1 811, mycorrhiza Azo-Fer= 1 783, mycorrhiza Azo-Fer + 60-30-00= 1 754) and mineral nutrition (2 685); however, different from the control (p≤ 0.05; 1 631). In morphological composition in both anthesis and milk grain state, there was no difference in stem biomass between the sources of nutrition (p≤ 0.05) and they were different from the control.
