Abstract: The objective of this work was to evaluate the efficiency of molten and ground alkaline potassium-silicate rocks (K1) and of ground phonolite rock (K2) as sources of potassium for upland rice (Oryza sativa) and common bean (Phaseolus vulgaris) crops, in comparison with the traditional source (KCl). Two experiments ? one with each crop ? were conducted on a Typic Haplorthox in a randomized complete block design with four replicates. The treatments consisted of three sources (KCl, K1, and K2) and four rates (0, 20, 40, and 80 kg ha-1 K2O) of K. Regardless of the used source, K fertilization increased the leaf K content and grain yield of the upland rice and common bean crops. The agronomic efficiency index (AEI) of the alternative K sources varied according to the crop. For upland rice, the AEI of K2 was 8% higher than that of KCl at the recommended K rate, but similar at the highest rate. For common bean, the AEI values of K1 were close to that of KCl at the rates of 40 and 80 kg ha-1 K2O. The alternative sources K1 and K2 supply K and increase the grain yield of common bean and upland rice, respectively, similarly to KCl. Resumo: O objetivo deste trabalho foi avaliar a eficiência de rochas potássio-silicáticas alcalinas fundidas e moídas (K1) e de rocha fonolito moída (K2) como fontes de potássio para as culturas do arroz de terras altas (Oryza sativa) e do feijão comum (Phaseolus vulgaris), em comparação à fonte tradicional (KCl). Dois experimentos ? um com cada cultura ? foram conduzidos em Latossolo Vermelho argiloso, tendo-se utilizado delineamento de blocos ao acaso com quatro repetições. Os tratamentos consistiram de três fontes (KCl, K1 e K2) e quatro doses (0, 20, 40 e 80 kg ha-1 de K2O) de K. Independentemente da fonte utilizada, a adubação potássica incrementou o teor foliar de K e a produtividade de grãos das culturas do arroz de terras altas e do feijão comum. O índice de eficiência agronômica (IEA) das fontes alternativas de K variou de acordo com a cultura. Para o arroz de terras altas, o IEA do K2 foi 8% mais alto que o do KCl na dose de K recomendada, mas semelhante na maior dose. Para o feijão, os valores do IEA do K1 foram próximos ao do KCl nas doses de 40 e 80 kg ha-1 de K2O. As fontes alternativas K1 e K2 fornecem K e aumentam a produtividade de grãos do feijão comum e do arroz de terras altas, respectivamente, de forma semelhante ao KCl.

Schizotetranychus hindustanicus Hirst (Acari: Tetranychidae) known as the Hindustan citrus mite, is a quarantine pest present in Roraima, Brazil. In 1924 this pest was described in India. It was reported in 2002 in Venezuela and in Roraima in 2008. In 2010, the Hindustan citrus mite was reported in Colombia. It is possible that it will be introduced in other areas of Brazil, resulting in a threat to Brazilian citrus industry. Our objective was to determine the most suitable regions of Brazil for S. hindustanicus using a maximum entropy (Max‑ ent) algorithm, based on native and invasive updated occurrence records from published research, field surveys and online databases. To avoid overfitting and improving transfer‑ ability, we chose parameter settings of Maxent to construct and validate models by searching for the best combination of feature classes and regularization multipliers. The model obtained showed excellent performance according to all evaluation metrics used. A high potential for the establishment of S. hindustanicus was identified in large areas of Roraima, the extreme west of Amazonas, the entire north of the State of Pará, also in northeast, south, east, and north of the State of Amapá, and in a small portion northwest of the State of Maranhão (all states belonging to the northern region of Brazil). Our results provide information for policy making and quarantine measures, especially where S. hindustanicus is still absent in Brazil. |
