“…Grown in practically all Brazilian regions, I. batatas is an excellent energy source due to its high carbohydrate and sugar content (MASSAROTO et al, 2013). It is used in human and animal food and has potential, as a raw material, to produce biofuels (ethanol) (SANTOS et al, 2010).…”

Pathogenicity of Metarhizium anisopliae and Beauveria bassiana fungi to Tetranychus ludeni (Acari: Tetranychidae)

The use of acaricides is the main control method for Tetranychus ludeni (Acari: Tetranychidae) in horticultural crops. This mite has been recorded causing damage to sweet potato (Ipomoea batatas L.). The use of pathogenic fungi is an alternative to chemical control. The objective was to evaluate the pathogenicity of the fungi Metarhizium anisopliae (Meetch) Sorok, and Beauveria bassiana (Bals.) Vuill. to phytophagous mite T. ludeni in sweet potato plants. Conidial suspensions of M. anisopliae and B. bassiana, at concentrations of 106 and 107 con.mL-1 were applied to sweet potato leaves. After 24 hours, five females of T. ludeni newly emerged were released on the leaves. The bioassay was arranged in a completely randomized design with factorial arrangement 2 × 2 (two species of fungi and two concentrations) plus the control (distilled water), with 10 repetitions per treatment. The evaluation consisted of observing of three biological parameters of the mite: mortality, oviposition, and repellency, after 24, 48, 72, and 96 hours of contact with the fungi. The isolates of M. anisopliae cause high mortality rates of T. ludeni in laboratory. Beauveria bassiana has the potential to suppress future generations of mite, reducing its oviposition rate. Repellency behavior was not observed.

“…In this regard, agroecological production has considerably increased the use of organic fertilizers in partial and sometimes even total replacement to mineral fertilizers. Among the organic fertilizers, bovine and poultry manure and Ribumin ® are highlighted (Santos et al, 2010a;Nsa et al, 2013;Silva et al, 2016b).…”

The use of organic fertilizers in adequate doses is an alternative to reduce the use of inorganic inputs, improving the soil chemical attributes, and increasing the production and quality of sweet potato. In this perspective, the objectives of this study were: (i) to evaluate the effects of fertilization with poultry and bovine manure, Ribumin®, and of conventional fertilization on soil attributes, production, and quality of sweet potato; and (ii) to evaluate the residual effect of organic fertilization on the production components and quality of sweet potato, in the second crop cycle. The two experiments were developed in the 2018/2019 crop year at the Agrotechnical School of the Federal University of Roraima (UFRR), Brazil. The treatments were arranged in a randomized block design with three replications, using a (2 × 5 × 2) + 1 factorial arrangement referring to two manure sources (bovine and poultry manure) and five doses, aiming at increasing the content of soil organic matter (1.35%) to 2.35; 3.35; 4.35, and 5.35%, in the absence and presence of Ribumin®, and an additional treatment referring to organomineral fertilization. For the evaluation of the second cycle, the residual effect of the manure was evaluated by applying only Ribumin® and conventional fertilizers. In the first cycle, the addition of 50.4 t ha-1 of bovine manure without Ribumin® provided the highest values of total (14.7 t ha-1) and marketable yield (14.6 t ha-1). However, the addition of poultry manure associated with the application of Ribumin® provided no increments in the sweet potato production components. Under the same experimental conditions, chemical fertilization can be replaced by fertilization with organic sources.

Sweet potato (Ipomoea batatas) has cultural, social and economic importance due to its rusticity and wide climate adaptation, being cultivated in Brazil for human and animal food. However, cultivation is carried out mainly without fertilization and with Creole cultivars. The objective was to evaluate the yield and quality of roots of sweet potato cultivars with and without fertilization of chicken manure in an Oxisol. The experiment was carried out under field conditions in the 2015/16 and 2016/17 seasons in a randomized block design with three replications in 6 m2 plots. Four sweet potato cultivars, BRS Rubissol, BRS Amélia, BRS Cuia and Crioula, were used. Root productivity, number, length and diameter of roots, and cracked roots were evaluated. In both cultivation conditions, the virus-free cultivars Rubissol, Amélia and Cuia showed higher average root yields, 43,941, 45,498 and 52,095 kg ha-1, respectively, compared to the Crioula cultivar with 3,389 kg ha-1. Fertilization with chicken manure does not increase the productivity, number, length and diameter of roots, but it does increase the number of cracked roots. The cultivation of virus-free sweet potato without fertilizer reduces cracked roots by an average of 51.4%.
