Response of the pea crop (Pisum sativum L.) to the application of organic fertilizers in the municipality of Pamplona, North of Santander. La Granja [online]. 2023, vol.37, n.1, pp.86-101.

In Pamplona pea production is based on the use of high doses of chemical fertilizers that cause environmental damage and human health. Therefore, in this study the effect of different organic fertilizers was compared with chemical fertilization through six treatments: T0: control; T1: vermicompost full dose (7831,00 kg/ha); T2: vermicompost half dose (3915.50 kg/ha) + chemical fertilizer (FQ 15N 15 15 O) half the dose (703.50 kg/ha); T3: chicken manure + goat manure + sugarcane residues full dose (ABOB: 10573.00 kg/ha): T4: ABOB half dose (1407.00 kg/ha) plus CF half dose (703.50 kg/ha); T5: CF full dose (1407.00 kg/ha); T6: CF half the dose (703.50 kg/ha). It was evaluated: plant height (AP), pods per plant (NVP); pod length (LV) and yield (kg/ha). A 5% analysis of variance and a Tukey test for separation of means were applied. The mean AP was higher in T2 (172.27 cm). NVP was higher in T3 and T5 with respect to the control, however, between treatments no statistical differences were observed. LV was statistically higher in the treatments compared to the control, although there was no variation between treatments. Although no statistical differences were observed in the performance between treatments, T1 and T4 presented a performance superior to the control of 42.85% and 39.99%, respectively. It is possible to substitute or supplement chemical fertilizer with organic amendments and reduce the negative effect of pollution that they generate on the environment and the health of the people.
