Resumen

This study evaluated the effects of partial biofertilization with Azolla filiculoides Lam. on growth, photosynthetic rate, bulb quality, and yield in Allium sativum L. cultivars ‘Chinese’ and ‘Napuri’ in Punta de Bombón, Arequipa, Peru (2018-2019). The research involved two experiments: one under monoculture with partial biofertilization + 1/2NPK (PBM) and conventional NPK fertilization (CFM), and the other in intercropping with maize (Zea mays), using both partial biofertilization + 1/2NPK (PBI) and conventional fertilization (CFI). Results showed that partial biofertilization outperformed conventional fertilization in monoculture settings. The ‘Chinese’ cultivar exhibited superior root, leaf, and bulb growth under partial fertilization, whereas ‘Napuri’ excelled in bulb quality components like dry weight, diameter, and clove number. Photosynthesis peaked at 82 days after sowing (DAS) for ‘Chinese’ and 112 DAS for ‘Napuri’. In terms of yield, ‘Chinese’ outperformed ‘Napuri’ in both monoculture and intercropping, with the highest yield recorded in 2019 (12641 kg/ha for ‘Chinese’ and 9597 kg/ha for ‘Napuri’). These findings suggest that combining chemical and organic fertilizers, along with crop diversification, can sustain high yields while being environmentally friendly.
