The fragility of agrosystems affects soil moisture and plant chlorophyll content, reducing productivity. The development of agricultural technologies that improve soil water status and plant physiology is therefore necessary. This study aimed to evaluate the effect of these practices on soil moisture and leaf chlorophyll in maize through a randomised complete block split-plot trial with three replicates. Three tillage methods (scarification, ploughing and partitioned ridge cultivation) were applied to the main plots. Two cropping systems (CS1: one row of maize alternating with one row of cowpea and CS2: two rows of maize alternating with two rows of cowpea) combined with five fertilisation levels (i) no fertilisation (F1), (ii) 200 kg ha-1 NPK + 200 kg ha-1 urea on maize + 100 kg ha-1 NPK on cowpea (F2), (iii) 300 kg ha-1 NPK + 100 kg ha-1 urea on maize + 100 kg ha-1 NPK on cowpea (F3), (iv) F2 +2500 kg ha-1 of compost (F4) and (v) F3 +2500 kg ha-1 of compost (F5) were applied to the secondary plots. The chlorophyll index of maize and soil moisture were assessed. Scarification resulted in significantly lower moisture content (14.28%) than ridge cultivation (17.98%) and ploughing (16.91%). SC1-F5 recorded a higher SPAD index (38.62). The combination of tillage, cropping system and organic-mineral fertilisation improves soil moisture and chlorophyll assimilation in maize.
Author Keywords: compartmentalised ridging, fertilisation, ploughing, cowpea, cropping system.

La fragilité des agrosystèmes affecte l’humidité du sol et la teneur en chlorophylle des plantes, réduisant la productivité. Le développement de technologies agricoles améliorant l’état hydrique des sols et physiologique des plantes est donc nécessaire. Cette étude visait à évaluer l’effet de ces pratiques sur l’humidité du sol et la chlorophylle foliaire du maïs à travers en blocs complètement randomisés avec des traitements arrangés en split-plot et trois répétitions et trois répétitions. Trois méthodes de travail du sol (scarifiage, labour et billonnage cloisonné) ont été appliquées aux parcelles principales et deux systèmes de culture qui sont (i) une ligne de maïs alternée d’une ligne de niébé et (ii) deux lignes de maïs alternées de deux lignes de niébé (SC2) combinés à cinq niveaux de fertilisation (i) sans fertilisation (F1), (ii) 200 kg ha-1 NPK+200 kg ha-1 urée sur le maïs+ 100 kg ha-1 NPK sur le niébé (F2), (iii) 300 kg ha-1 NPK+100 kg ha-1 urée sur le maïs + 100 kg ha-1 NPK sur le niébé (F3), (iv) F2 +2500 kg ha-1 de compost (F4) et (v) F3 +2500 kg ha-1 de compost (F5) ont été appliqués aux parcelles secondaires. L’indice chlorophyllien du maïs et l’humidité du sol ont été évalués. Le scarifiage a présenté une humidité (14,28%) significativement plus faible que le billonnage cloisonné (17,98%) et le labour (16,91%). Le SC1-F5 a enregistré un indice SPAD plus élevé (38,62). L’association du travail du sol, du système de culture et de la fertilisation organo-minérale améliore l’humidité du sol et l’assimilation chlorophyllienne du maïs.
