Abstract:
Pigeonpea, Cajanus cajan (L.) Millspaugh, is one of the major pulse crop of the tropics and subtropics also popularly known as red gram, tur or arhar. It is a primary source of protein for millions in India. Sterility mosaic disease (SMD) caused by mite (Aceria cajani) is a major disease limiting the pigeonpea production in the Indian subcontinent. The field experiment was conducted during the year 2018-20 at RARS, Warangal to study the effect of abiotic factors on mite population and disease incidence of sterility mosaic disease. Among the various factors studied relative humidity and wind speed had a strongly positive with mite population. The studies on effect of different sowing dates on sterility mosaic disease was observed and be concluded that sever disease incidence was observed with late sowing of the crop i.e., from First week of August than early (before June 15^th) or on timely sowing (June 15^th to July 15^th) of the crop.
