| ABSTRACT For proper plant growth and achievement of satisfactory yield, it is essential to replenish water and nutrients, in the right amount and time. Therefore, the aim of this study was to evaluate the effects of soil water potential and lithothamnium doses on the growth and yield of bell pepper fruits in an organic production system. The experimental design was randomized blocks in a 5 x 4 factorial scheme, with four replicates. The treatments were five lithothamnium doses (0, 0.5, 1, 2 and 4 g dm-3) and four soil water potentials (-6, -24, -42 and -60 kPa). Increasing lithothamnium doses and irrigations based on increasing soil water potentials produced linear increase in plant growth and fruit production. The maximum economic efficiency of the... |
