- Successive crops of broccoli, green corn and pea after taro (Colocasia esculenta) - sunn hemp (Crotalaria júncea) consortium Joao Nacir Colombo Mario Puiatti Ricardo Henrique Silva-Santos Luiz Antônio dos Santos-Dias Henrique Colli-Silvestre Agrociencias italica Zea mays L Pisum sativum Crotalaria júncea Colocasia esculenta Aiming to assess the residual effect of the biomass of the taro-sunn hemp consortium on the performance of the successive crops of broccoli, green corn and peas, an experiment, with 11 treatments, corresponding to the cutting of Crotalaria júncea in the taro-sunn hemp consortium (55, 70, 85, 100, 115, 130, 145, 160, 190 and 220 days after sowing - DAS) plus a control treatment (Colocasia esculenta), was performed. Soil samples were collected and chemical analysis was performed before crop establishment. Plant characteristics and productivity of broccoli, green corn and pea pods were assessed. There were no major changes in soil chemical composition. Higher values of inflorescence fresh matter and broccoli yield were observed in the treatments in which cuts of Crotalaria júncea occurred 145 DAS. The residual effect of Crotalaria júncea cuttings provided higher corn plants and a greater fresh matter of spikes with straw and productivity of commercial ears, compared to the control. There was no residual effect on the characteristics evaluated for pea. The residual effect of Crotalaria júncea cropped in a consortium with Colocasia esculenta increases broccoli yield when cut from 145 DAS and corn cropped in succession. 2020 artículo científico 0120-2812 https://www.redalyc.org/articulo.oa?id=169969274010 https://www.redalyc.org/journal/1699/169969274010/ https://www.redalyc.org/journal/1699/169969274010/html/ https://www.redalyc.org/journal/1699/169969274010/169969274010.epub https://www.redalyc.org/journal/1699/169969274010/movil 10.15446/acag.v69n4.61794 en http://www.redalyc.org/revista.oa?id=1699 Acta Agronómica application/pdf Universidad Nacional de Colombia Acta Agronómica (Colombia) Num.4 Vol.69
