- Abstract
Organic fertilizers are key ingredient of organic farming systems for safer environment, healthier, safer food production and suppression of some insect pests. In this work, the effect of four organic soil fertilizers (vermicompost, compost, cattle manure and chicken manure) on the population of two major tomato pests (Tuta (T.) absoluta and Bemisia (B.) tabaci) and tomato productivity in Egypt was investigated. The experiments took place in a plastic greenhouse in the Nubaria region (30.76658, 30.29312). The greenhouse comprises of 10 rows with a length of 10 m and apart of 1 m. Two rows each was defined for one type of fertilizer (treatment) and divided into five repetitions (approx. 30 plants each). Insect populations were expressed as numbers of eggs and larvae of T. absoluta and eggs and nymphs of B. tabaci. Insect damage was expressed as the number of pores induced in tomato fruit. The results showed a significant effect (Two-Way ANOVA) of all organic fertilizers, particularly cattle and chicken manure, causing the largest increase in tomato production and the largest population decline and damage from the two pests. Cattle manure is recommended for use in Egypt due to its lower cost and greater availability.
