Resumo: | ABSTRACT Fertigation can be managed using fixed fertilizer doses or by assessing the ionic concentration of soil solution throughout the growing period. This work studied how different fertigation management systems affected sweet pepper yield and quality. The experiment was carried out in greenhouse, in pots. Fertigation was managed according to the crop uptake rate (M1) or by monitoring either the electrical conductivity (M2) or the N and K concentration (M3) in the soil solution. Fertigation management was combined with six N and K doses (0, 50, 100, 150, 200 and 300% of the recommended dose for sweet pepper in the region), in complete blocks at random, with four replications, and treatments in 3x6 factorial. Dry matter accumulation, yield and fruit grading were evaluated. Fertigation managed by means of monitoring the soil solution improved the vegetative growth in up to 25% and increased yield in up to 20% when compared to management according to the uptake rate. Highest fruit yields in M1, M2 and M3 were achieved with N and K levels corresponding to 127.6% (1.33 kg/plant), 222.5% (1.60 kg/plant) and 215% (1.48 kg/plant), respectively. N and K can be supplied successfully to sweet peppers using electrical conductivity or concentration of ions in the soil solution to manage fertigation. These management systems resulted in high quality fruits and up to 47% increase in N and K use efficiency. N and K concentration equivalent to 200% of the recommended for growing sweet pepper in hydroponics should be taken as reference. |
