1. Influence of humus on chromium absorption by coffee seedlings grown on substrate containing tannery sludge
ABSTRACT Chromium is present in the tannery sludges worldwide making it a problem for agriculture. This study aimed to evaluate whether humus functions as a chromium stabilizing agent when using tannery sludge in the substrate of conilon coffee seedlings (Coffea canephora) and to determine what effects there are on leaf development and anatomy. Treatments co

2. USE OF REMOTELY PILOTED AIRCRAFTS FOR THE APPLICATION OF PLANT PROTECTION PRODUCTS
ABSTRACT The use of remotely piloted aircrafts (RPAs) to apply plant protection products has grown a lot in agriculture worldwide. However, little research data are available regarding the efficiency and safety of this method, especially in Brazil. Thus, this review aimed to present the current scenario of scientific research involving RPAs in the applicatio

3. DESIGN AND IMPLEMENTATION OF FLC APPLIED TO A SMART GREENHOUSE
ABSTRACT Greenhouse cultivation needs an accurate modelling and an optimised control system to ensure an adequate microclimatic condition for plants. It represents a complex task due to the high number of input factors. For this reason, an improved intermediate modelling was established under the platform of the MATLAB/Simulink environment to simulate the en

6. ACHPA: A sensor based system for automatic environmental control in hydroponics
Abstract The trend towards tunnel farming and hydroponic systems is increasing owing to the climatic changes as well as the need to increase crop yield. Hydroponic is a technique of growing plants without soil. Tunnel farming and hydroponic system requires controlled environmental parameters like temperature, humidity and soil moisture for better production

9. Potential utilization of spent Agaricus bisporus mushroom substrate for seedling production and organic fertilizer in tomato cultivation
RESUMO A produção de Agaricus bisporus resulta em material residual significativo após seu cultivo. O substrato pós-cultivo do cogumelo (SMS), devido às suas propriedades físicas e conteúdo de nutrientes, tem um grande potencial para uso na agricultura. Nosso estudo avaliou a viabilidade do uso do SMS como substrato alternativo para a produção de mu
