Objective : The present study aims to compare the fertilizing quality of green algae (Azolla caroliniana), compost and NPK applied to tomato in the Daloa area (Côte d'Ivoire). The parameters evaluated are the vegetative growth and yield of these tomatoes. Methodology and results : The trial is performed as a randomized, complete block of four treatments (Azolla caroliniana, compost, NPK and Control) in four replicates. Data are collected on the vegetative cycle of crops. The treatments were compared according to the vegetative parameters : stem height (ht), neck diameter (dc), leaf length (lf) and yield (r). Except NPK treatments received 200 kg / ha for NPK and 100 kg / ha for urea, treatments are fertilized at the same manure rate (30 t / ha). The results indicate Azolla caroliniana statically differ. The average of (ht) is 49.37 ± 0.55 cm with Azolla caroliniana against 37 ± 1 cm for NPK, 34.57 ± 2.2 for compost and 22.95 ± 0.24 for control, except the growth of (dc) where the smallest difference was not significant. (Dc) is 0.71 ± 0.08; against 0.57 ± 0.03 for NPK, 0.55 ± 0.08 for compost and 0.42 ± 0.07 for the control. Yield was high with Azolla caroliniana (26.13 ± 0.86 t / ha tomato) at a density of 37500 plants / ha. Conclusion and application of results:This study shows that Azolla caroliniana gives a high yield with a high density, restores good soil fertility and increases the productivity of the tomato crop.

In the search for biological substances for sustainable agriculture, the present study proposes to use fungal biofertilizers to improve the production of tomato crop. Thus, two species of dried superior fungi (Psathyrella tuberculata and Daldinia concentrica) were milled for use as soil fertilizer. Psathyrella tuberculata, Daldinia concentrica and a combination of P. tuberculata+D. concentrica were used as organic fertilizer for tomato plants grown from COBRA 26. The effect of these three fertilizers was compared with NPK 10-18-18 and the control. The results showed that the fungal fertilizers contributed to the improvement of tomato production. The highest values for the parameter number of fruits were obtained with the first group consisting of plots that received PSTU (2.42), DACO (2.75), NPK (2.75), PSTU+ DACO (3.00) and the lowest value on the plot TEMOIN (0.41). The combination of PSTU+DACO (3.00) gave the statistically higher values than the other fertilizers. The highest yield was recorded on the plots enriched with PSTU+DACO (6.67 t/ha). From the 30th DAR onwards, plants from plots fertilized with DACO, PSTU+DACO and PSTU started to flower. From 37 to 44 days, the plots with the highest number of flowering plants were those treated with PSTU (28 plants).
