Influence of planting time, planting geometry, intercropping and row direction on rust (Uromyces viciae fabae) pers. de bary of field pea (pisum sativum L.)

A field experiment was conducted during 1999–2000, 2000–2001 and 2001–2002 to study the effects of cultural practices viz., planting time, planting geometry, intercropping and row direction on disease severity of field pea rust caused by Uromyces viciae fabae and grain yield. Among different time of plantings tested, 13^th December planting has recorded the highest disease severity and minimum grain yield. It was also noticed that planting geometry i.e. row spacing has significant influence on disease severity. The minimum disease severity was recorded in plots having wider row spacing (45 cm) followed by 37.5 and 30 cm. Similarly, minimum rust severity was recorded when field pea was intercropped with mustard. However, planting direction has not significantly influenced rust severity under Pantnagar (Uttarakhand) condition.
