Abstract

This study was developed to investigate the interactive effect of silicon (Si) application and the inoculation of plant growth promoting bacteria (PGPB) Azospirillum brasilense on wheat nutrient uptake and accumulation on biomass and grains when combined with nitrogen (N) application rates. The study was set up in a Rhodic Hapludox under no-till system, located in Selvíria, state of Mato Grosso do Sul, Brazil (tropical Savannah region). Treatments were tested in a randomized complete block design with four replicates, arranged in a full factorial design 2 × 2 × 5 and included: i) two soil amendment sources (Ca and Mg silicate as Si source and dolomitic limestone); ii) two seed inoculation (with and without A. brasilense) and iii) five N application rates applied as side-dress (0, 50, 100, 150 and 200 kg ha−1). Increasing N application rates positively influenced wheat nutrition with increased nutrient and Si uptake in shoot. Calcium and Mg silicate positively influenced wheat nutrition with greater shoot Si and grain N, P, K, B, Cu, Fe, Mn, Zn and Si uptake. In addition, Si was the third and sixth element most absorbed in wheat shoot and grain respectively. Inoculation with A. brasilense was found to increase nutrient uptake with greater shoot K and S and grain N, P, K, Mg, S, B, Cu, Mn, Zn and Si uptake. Azospirillum brasilense inoculation provided greater N uptake, with an increase of 5.8 and 8.9% on shoot and grain uptake.

Abstract

This study was developed to investigate if Ca and Mg silicate application as Si source combined with inoculation with Azospirillum brasilense and N rates can affect corn nutrient uptake. The study was set up in a Rhodic Hapludox under no-till system, located in Selvíria, state of Mato Grosso do Sul, Brazil. Treatments included: (i) two seed inoculation (with and without A. brasilense); (ii) two soil amendment sources (Ca and Mg silicate as Si source and dolomitic limestone); and (iii) five N application rates applied as side-dress (0 to 200 kg ha−1). Increasing N rates positively influenced corn nutrition with increased nutrient and Si uptake in shoot and grain. The average nutrient uptake in descending order was K > N > Ca > Si > Mg > S > P >Fe > Mn > Zn > Cu > B for shoot and N > K > P > S > Mg > Ca > Si> Fe > Zn > Mn > B > Cu for grain. Calcium and Mg silicate application positively influenced corn nutrition with greater shoot P, K, Ca, S, and B uptake and grain Ca uptake. Inoculation with A. brasilense was found to increase nutrient uptake with greater shoot N, K, Ca, B, and Si and grain Cu uptake. Grain N and S increased by 22.5 and 26.8% when plants were inoculated and 200 kg N ha−1 was applied and grain Zn increased by 88.6, 65.7, and 99% when plants were inoculated and 50, 150, and 200 kg N ha−1 were applied, respectively. Therefore, studies conducted under tropical conditions are needed to better understand the role of Si combined with PGPB inoculation under different N management and their effects on plant nutrition and cereal development aiming at improving nutrient replenishment.

Abstract

The interactive effect of silicon (Si) application on soil fertility is poorly understood when inoculation with Azospirillum brasilense is performed. This research determined if Si application and A. brasilense inoculation to corn (Zea mays L.) and wheat (Triticum aestivum L.) has agronomic benefits on soil nutrient concentration and grain yield. Treatments were tested under a no-till system in a Rhodic Haplustox in a full factorial design with four replicates and comprised (a) two soil amendment sources--calcium (Ca) and magnesium (Mg) silicate and dolomitic limestone; (b) with and without seed inoculation with A. brasilense; and (c) five sampling dates collected during two corn-wheat crop rotations (2015-2017). Calcium and Mg silicate application was effective at decreasing soil hydrogen + aluminum (H+Al) and Al content and increasing soil pH, sum of bases, and base saturation. However, silicate changed soil nutrient availability, reduced cation exchange capacity, phosphorus (P) and Mg content and did not significantly affect (p > .05) corn and wheat grain yield. Inoculation reduced Al toxicity, with lower H+Al and Al contents, and increased K content, leading to a greater pH and base saturation after four cropping seasons. Inoculation increased corn and wheat grain yield by 8.2 and 8.3%, respectively. Application of Ca and Mg silicate was more effective than limestone as a liming agent but could result in decreased availability of certain nutrients in soil. Inoculation with A. brasilense could be an important management practice to maintain adequate Si content in soil when limestone is applied. However, with silicate application, A. brasilense could increase Si depletion in soil. [ABSTRACT FROM AUTHOR]

Abstract

Wild poinsettia (Euphorbia heterophylla) is one the most important weeds in soybean fields in the state of Paraná, not only for its dissemination, but also due to its natural difficulty of controlling features by herbicides and to occurrence of resistant biotypes. Facing those problems, an evaluation of the field and greenhouse trials was carried out in order to check the efficacy of postemergence sequential application of flumicloracpentil to control this weed. Sequential applications of flumicloracpentil were more efficient than a single application, promoting, at least, 86% of weed control on the 24th day after the second application of the sequential treatments. All the evaluated combinations of flumiclorac rates once sprayed at two true leaves stage, promoted adequate control of E. heterophylla. Comparing the greenhouse and the field results, it was concluded that, under field conditions, the canopy provided by the crop helps to improve the weed final control. Euphorbia heterophylla destacase como a principal planta daninha na cultura da soja no Estado do Paraná, não só pela sua disseminação, mas também pela natural dificuldade de controle e pela ocorrência de biótipos que apresentam resistência. Em face de tais problemas, buscouse avaliar a eficácia de aplicações seqüenciais em pósemergência de flumicloracpentil no controle dessa planta daninha. As aplicações seqüenciais de flumicloracpentil foram superiores, em termos de eficácia, às doses recomendadas em aplicação única, promovendo no mínimo 86% de controle aos 24 dias após a aplicação da segunda etapa das seqüenciais. Todas as combinações de doses de flumicloracpentil avaliadas promoveram controle adequado de E. heterophylla, desde que aplicadas no estádio de duas folhas verdadeiras. Comparandose os resultados obtidos em casadevegetação e em estufa, observouse que, em condições de campo, o sombreamento imposto pela soja auxilia no nível de controle final da planta daninha.
