Effect of solarization with fresh chicken manure on verticillium wilt (<i>Verticillium dahliae</i> Klebb) and yield in eggplant

Abstract

The present study was carried out to evaluate the effect of reducing wilt disease through the medium of fresh chicken manure (FCM) mixed with soil before solarized and then artificial Verticillium dahliae (V.d) inoculation on yield of eggplant (Solanum melongena L.) under field conditions. According to the splitplot design, solarization of main plots, sub-plots with fresh chicken manure and V dahliae inoculation were established as a mini parcel in experiment with three replications. During solarization, the average temperature values were ensured by means of increasing the fresh chicken manure per unit area recorded 24 times per day (24 h) at intervals of one week. Among the 6 applications form, the highest average temperature was obtained at “12 kg FCM m^-2 +solarization” application for soil surface, 10, 20 and 30 cm depth. There was increasing 18°C, a temperature according to control (no FCM), and this difference decreased with increasing soil depth, which was calculated as 8°C at 30 cm depth soil. During the day, the highest temperature values were obtained in the middle of the day on the ground, and underground measurements were performed at night.
