| The objective of this study was to evaluate the effect of bio-stimulant on the vegetative and reproductive aspects of dwarf-coconut over a period of 13 months in the state of Ceará. The experiment was conducted from September 2016 to October 2017, in a commercial production area, located in the municipality of Itarema, state of Ceará, using four-year-old plants, in a triangular spacing of 8 x 8 x 8 m in blocks at random, four doses of Crop-Set bio-stimulant plus control (0; 4; 8; 12 and 16 mL plant-1) with four replications. The Crop-Set bio-stimulant was applied through leaves with a back-pack spray, in the axilla of the ninth leaf of the coconut palm for 13 months. After its application, the number of leaves, flowers, fruits and bunches per plant was... |

| ABSTRACTThe castor bean crop plays an important social, environmental and economic role, especially due to possibility of its use as feedstock for the generation of clean energy. Thus, this study aimed to evaluate the contents of photosynthetic pigments, cell membrane extrusion and the relative water content in the leaves of the castor bean cultivar ‘BRS Energia’ under silicon and salinity levels. The experiment was carried out at Embrapa Cotton, in a completely randomized design, in a 4 x 4 factorial scheme, and the treatments consisted of four silicon levels (0, 100, 200 and 300 mg L-1) and four water salinity levels of (ECw 0, 2, 4 and 6 dS m-1), with three replicates. The gradual increase in salinity levels reduced the concentration of photosynthetic... |
