Title

EVALUATION OF PLANTING TIME AND PLANTING SPACE EFFECTS ON INTERACTION BETWEEN BEHBAHAN IMPROVED ONION POPULATION AND PERONOSPORA DESTRUCTOR

Pages

  17-24

Abstract

 Peronospora destructor is casual agent of ONION DOWNY MILDEW disease and is one of the most destructive diseases in humid and cool regions. The different ways to control this disease include fungicide application, change of planting date and use of resistant cultivar. This study was done in improved population of Behbahan ONION in order to evaluate the effects of planting date and distance between and in rows on the disease incidence with the aim of nonchemical control of the disease. This study was conducted in factorial experiment as randomized complete block design with 36 treatments and 4 replications in Behbahan Agricultural Research Station. Four PLANTING TIMEs (to produce seedling) including 6 Sep, 21 Sep, 6 Oct and 21 Oct were considered as main plots and 3 planting distances; 20, 30 and 40 cm between rows and 5, 7.5 and 10 cm between plants on rows as sub plots. The results showed that there was significant difference between PLANTING TIME (P<1%) and between PLANTING SPACEs (P<5%). The disease severity was reduced to (18.19%) incase of the planting date test (21 Oct.). The Disease severity was 18.19% and 72.71% in 40 cm and 20 cm spacing between rows respectively. Also disease severity was 70.42% and 64.48% in 5 cm and 10 cm spacing between plants on rows respectively.
