Abstract

Root rot caused by Phytophtora capsici is one of the most important root diseases of pepper. The experiment was conducted at Denbiya and Takusa district with aimed to evaluate effective red pepper varieties and types of seed bed against root rot disease. Five red pepper varieties namely Melka Dera, Melka Oli, Melka Zala, Marco Fana, local; and two seed bed types namely flat and raised bed were used as treatments. Treatments were arranged in a factorial combination in RCBD with three replication. Result showed that the minimum incidence and severity of 28.13 % and 19.8%, respectively was recorded from Melka Oli variety transplanted in a raised bed while the maximum incidence and a severity of 51.03% and 42.8%, respectively were recorded from local red pepper in flat seed bed. The maximum grain yield of 28.81 q/ha and insignificance yield losses were recorded from Melka Oli in raised beds while the minimum grain yield and maximum yield losses 11.12q/ha and 61.44%, respectively were recorded from local red pepper in flat seed bed. Therefore, results suggested that the use of Melka Oli variety transplanted at raised seed bed is promising for significant reduction in root rot incidence and a corresponding increase in yield of red pepper.

Highlights

Red pepper(Capsicum frutescence L.) is one of the most important vegetable crop in the world belonging to the family Solanaceae and grown as spice crop in different parts of the world [1]
Two-way interaction effect of red pepper varieties and types of seed bed were highly significant at P < 0.01 on root rot disease incidence percentage (Table 1)
56.71% at Denbiya district were recorded from local pepper which was transplanted at flat seed bed, whereas the minimum root rot incidence of 32.70% was recorded from Melka Oli variety which was transplanted at raised seed bed (Table 2)

Summary

Introduction

Red pepper(Capsicum frutescence L.) is one of the most important vegetable crop in the world belonging to the family Solanaceae and grown as spice crop in different parts of the world [1]. It covers 67.98% of all the area under vegetables in Ethiopia [2]. Red pepper is a popular vegetable and plays an important role in the national economy of the country. It serves as row material for the processing industries, important cash crop to farmers, and a source of employment to urban and rural populations [3]. Red pepper production for dry pod has been low with a national average yields of 1.8 t/ha and declining with time [2, 4]
