ABSTRACT - The objective of this work was to evaluate the effect of decreased spacing between 'Roxo de Valinhos' fig (Ficus carica) trees with different numbers of fruiting branches on green fig production. Fig trees, with two or four fruiting branches, were distributed in four blocks, at a standard spacing of 2.5 m between rows, three spacing between plants in a row (0.50, 0.75, and 1.00 m), and densities of 8,000, 5,333, and 4,000 plants per hectare. The experiment was conducted during two cycles (2020/2021 and 2021/2022). Green fruits were harvested twice a week, and the total number of fruits per harvest and the total harvest weight per plant were quantified. The average production per plant and the estimated yield were calculated for each evaluation cycle. Decreasing the spacing between fig trees increases their yield. The spacing of 0.50 m decreases production per plant, but increases yield in 73%. There is no difference in the production of green figs between trees with two or four fruiting branches. RESUMO - O objetivo deste trabalho foi avaliar o efeito da diminuição do espaçamento entre figueiras 'Roxo de Valinhos' (Ficus carica) com diferentes números de ramos produtivos na produção de figos verdes. As figueiras, com dois ou quatro ramos produtivos, foram distribuídas em quatro blocos, com espaçamento padrão de 2,5 m entre linhas, espaçamentos entre plantas na linha de 0,50, 0,75 e 1,00 m, e densidades de 8.000, 5.333 e 4.000 plantas por hectare. O experimento foi conduzido durante dois ciclos (2020/2021 e 2021/2022). Os frutos verdes foram colhidos duas vezes por semana, tendo-se quantificado o número total de frutos por colheita e o peso total de colheita por planta. A produção média por planta e a produtividade estimada foram calculadas para cada ciclo de avaliação. A diminuição do espaçamento entre as figueiras aumenta a sua produtividade. O espaçamento de 0,50 m diminui a produção por planta, mas aumenta a produtividade em 73%. Não há diferença na produção de figos verdes entre as figueiras com dois ou quatro ramos produtivos.

The LTCC technology (Low Temperature Co-fired Ceramics) has become much more versatile than any technique applied so far in the field of miniaturization, since allowing the construction of threedimensional devices quickly and easily. Due to the ease of handling, the green ceramic provide the multilayer arrangement of modules with different applications, such as, among others, in the field of microelectronics and manufacturing microvalves and microfluidic systems applied in flow injection systems. Natural materials, available in large quantities and that can be used as low cost adsorbents for wastewater treatment have been the target of numerous studies. As an example, chitosan, zeolites, natural sponges and activated carbon are used successfully for this purpose. Zeolites are natural or synthetic minerals, with a wide variety of technological applications. Its structure has channels and cavities in which it is possible to settle ions, water molecules or other adsorbates and salts. This study aimed to investigate the removal capacity of Cd, Cr, Cu, K, Ni and Zn by a sample of natural zeolite ceramic integrated devices through the LTCC technology. Ceramic systems with 2.6 cm long and 1.7 cm wide were constructed with natural zeolite integrated inside. The experimental parameters were optimized employing 10 mL of a 5 mg L-1 containing Cd, Co, Cr, Cu, K, Ni and Zn. The influence of pH and time on adsorption of metals by natural zeolite was evaluated. After the adsorption step solutions were analyzed by optical emission spectroscopy with inductively coupled plasma (ICP OES) for the analytes determination. The results showed that the determining factor in the adsorption capacity of natural zeolite is the pH of the solution. In the pH range of 6 up to 7 the competition adsorption of analytes was not observed. Values above 88% of adsorption were obtained for all metal ions studied. The kinetic study indicated that equilibrium was reached in approximately 2 hours of contact between the solution and natural zeolite. The results demonstrated the viability in the adsorption of Cd, Co, Cr, Cu, K, Ni and Zn in natural zeolite integrated ceramic systems, and the pH factor in optimizing the adsorption capacity of zeolite.
