Management of Uromyces viciae–fabae (Pers.) J. Schrot. in Pisum sativum L. through alteration in sowing time

Abstract

Present study was conducted for crop seasons 2013-2014 and 2014-2015 to know the effect of alteration in date of sowing on rust severity and grain yield in field pea. The results of investigation indicate that, early sown crop in 31st October, 7th November and 14th November face lower disease severity (8.67-17.50 percent) with low area under disease progress value (81-198.67) and produce good yield (690.90-775.39 kg/ha) and test weight (162.34-175.34 g) whereas crop sown in 21st November, 28th November, 5th December and 12th December succumb to high disease severity (40-54.17 percent) showing high area under disease progress value (383.50-549.17) with low yield (429.06-581.95 kg/ha) and test weight (146.67-153.73 g). When disease severity at most susceptible stage (110DAS) in different sowing dates were correlated with weather factors, it was found that maximum and minimum temperature were significantly positively correlated whereas relative humidity, rainfall and wind velocity showed negative correlation.
