Effect of Date of Sowing and Climate Change Variables on Greengram [Vigna radiata (L.) Wilczek] Anthracnose Caused by Colletotrichum truncatum

Year: 2020

Type: article

Abstract: Greengram is an important pulse crop of India and being affected by anthracnose disease. The experiment was conducted to study the influence of weather variables on anthracnose disease severity during Kharif, 2018 with three different dates of sowing viz., on 29th July, 8th August and 13th August 2018. Disease severity was minimum in the crop sown on 29th July when compared with crop sown on 13th August due to favourable conditions led to build up the inoculum which has spread and caused more disease. The effect of CO2 and temperature was studied in the open top chambers (OTCs) maintained by Centre of Climate Studies, Main Agricultural Research Station (MARS), Raichur under five sets of treatments. Among them, ambient CO2 at 410 ± 25 ppm with 2 ºC rise in temperature showed higher disease severity of 7.00 per cent with reduced growth parameters of greengram compared to open plot experiment.
