Effect of the application of plant growth-promoting microorganisms on the cultivation of two varieties of chard (beta vulgaris L. subsp. cicla) under greenhouse conditions

Abstract

Agroecological and sustainable vegetable production arises from the need to produce safe food and protect the environment and with the aim of obtaining sustainable and environmentally friendly agriculture but achieving the best productivity results. Therefore, this work aimed to study the effect of the application of the consortium of native microorganisms on the quality and yield of the crop of two varieties of chard (Beta vulgaris L. subsp. cicla) at the time of transplantation. The trial was carried out in the greenhouse of the Faculty of Agricultural Sciences of the National University of Catamarca. Swiss chard of the white and rainbow varieties was sown in germination trays. The seedlings were transplanted in beds and inoculated with native plant growth-promoting microorganisms at the time of transplantation. Fresh weight and number of leaves per plant and time of harvest were recorded. The design was in randomized blocks with 4 replications; data were subjected to analysis of variance and LSD test (p≤0.05). Plants inoculated with the microbial consortium produced significantly higher yields than control plants. The number of cuts and the yield of the Rainbow variety increased significantly progressively with inoculation.
