Organo-biological amendments on tomato production

Evaluation of the effect of organo-biological amendments on tomato (Lycopersicon esculentum mill. Solanaceae) production. The objective of this work was to evaluate the effect of three organo-biological amendments (bokashi, simple compost, compost enriched with trichoderma harzianum) on the development of tomato in the village of Soala. Treatments were compared according to vegetative parameters: stem height, collar diameter, number of plants and fruits at harvest as well as the weight of these different fruits. The results indicate no significant difference between the different organic fertilizers compared to the control plots and those fertilized with NPK and urea. The results of the number and weight of fruits indicate a significant difference between plots T3 (amendment with Bokashi) and T4 (amendment with compost enriched with Trichoderma harzianum) compared to the control and conventional plots. The chemical analysis of the soils shows an improvement in the quality of the soils after amendment following the increase in the quantity of organic matter from 0.16% to 12.81%.
