Abstract
The aim of this study was to monitor the development of the maize plant depending on the preceding plant (rye; alfalfa for forage), with the objective of promoting crop rotation with alfalfa jumping plots within the agricultural system practiced on sandy soils. The results obtained showed that alfalfa incorporated into the soil after five years had a positive effect on soil fertility and implicitly on the behavior and productivity of maize. Thus, the content of organic matter, left in the soil after incorporating alfalfa, was 4.3 times higher than that recorded in the soil with the preceding plant rye. The beneficial role of the alfalfa precursor plant was highlighted on the stress behavior of the maize plant, which best regulated its resistance mechanism to stress conditions by binding at the cellular level a percentage of water bound to 3.03%, higher by 0.43% compared to maize sown after rye. Also, the maize sown after alfalfa showed better character stability, the coefficients of variability having lower values compared to the maize grown after rye, and at harvest the grain production was 27.9% higher, compared to the sown after rye, the difference in production being statistically significant.
