Abstract
The objective of this experiment was to study the effect of different NH4+/NO3– ratios on the growth, production and quality of three aromatic herbs: chives (Allium schoenoprasum), basil (Ocimum basilicum L.) and dill (Anethum graveofens L.). The herbs were cultivated in a hydroponic system with drip irrigation.
A mixture of volcanic rock, locally called tezontle and coconut fiber (60:40) was used as substrate.
The universal Steiners nutrient solution was modified to obtain 4 different NH4+/NO3– ratios (0/100, 20/80, 40/60 and 100/0). In chives, the 0/100 ratio significantly increased the leaf area and total biomass production.
The greater height, leaf area and total biomass production were obtained in basil with the 20/80 ratio.
No significant differences were observed in dill.
