The objective of the research was to evaluate the effect of organic mineral fertilization on the production of purple corn (Zea mayzL.) in the community of Rurunmarca, Caja Espíritu district, Acobambaprovince, Huancavelica Region, of November 2019 to May 2020 in which six fertilizations were evaluated: AO 75% + NPK 25%; AO 50% + NPK 50%; AO 25% + NPK 75%; AO 100% + NPK 100%; AO 100% and NPK 100% and a witness. These were distributed in a completely random block design. The variables evaluated were number, weight and yield of corn cobs, and profitability of fertilizations. The results indicate that fertilizations with high proportions of soluble nutrients significantly increase the number and weight of purple corn cobs by unit surface, consequently mineral organic fertilization if it influences the yield of purple corn cobs by unit area and the best cost-effective alternatives for growin...

The objective of this research was to evaluate the effect of mycorrhizals and actinomycetesoncorncultivation, Ccarhuay variety (Zea mays L) in the greenhouse of biological tests of the National University of Huancavelica. The experiment was evaluated using the Random CompletelyBlocksDesign, with 5 treatments (Huachaybamba 1 Micorrized Soil (SMH1), Pomavilca 2 Mycorred Soil (SMP2) Soil withActinomycete of Chupa1 (SACH1),soilwithActinomyceteofPueblo Viejo 2 (SAPV2), and“Común Era” soil,as Witness(T))distributedin5blocks,and25 experimental units. Plant height, stem diameter, number of leaves per plant, root length, vigor index,fresh and dry weight of root and foliar biomass were evaluated. The results indicate that soils with mycorrhizals and actinomycetes do not influence root length, but increase plant height, fresh and dry weight of root biomass.Soilswithactinomycetesincrease thedia...

This research was conducted in the community of Tranca Pampa- District of San Marcos de Rocchac, province of Tayacaja Department of Huancavelica, Peru; in the agricultural campaign 2019- 2020, with the objective of evaluating the effect of human urine enriched with efficient microorganisms on the yield of potato, peruanita variety. A randomized complete block experimental design with three replications was used to test the effect of 5 liters of urine plus EM, 10 liters of urine plus EM, 15 liters of urine plus EM and a witness without application. Plant height at 120 and 210 days, number, and weight of tubers per plant at harvest were evaluated. Analysis of variance and Duncan's multiple comparison tests of means at =0.05 were performed. The best yields were obtained with the application of 15 liters of urine plus EM (75.53 t ha-1) and 10 liters of human urine plus EM (73.48 t ha-1), ...
