Effect of two fungal fertilizers (Psathyrella tuberculata and Daldinia concentrica) on the production parameters of tomato (Solanum lycopersicum L.) in Daloa (Centre-West, Côte d’Ivoire)

Abstract

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).
