dc.description.abstractThe present study entitled “Effect of microclimate on white rust of mustard under open and poplar plantation” was conducted at the Research Farm of Department of Climate Change and Agricultural Meteorology and Research Farm of Department of Forestry and Natural Resources, Punjab Agricultural University, Ludhiana, during the rabi season of 202122. The experiment was conducted under split plot design with 3 replications having three dates of sowing (10th October, 5th November and 1st December) and two varieties (PBR-91 and Giriraj) in main plot with three nitrogen levels treatment (N1: Recommended N, N2: Recommended N+25%, N3: Recommended N+50%) in sub plots. Incidence and severity of white rust was recorded from 5th to 12th standard meteorological week under both the growing environments. The micrometeorological parameters like PAR interception, canopy temperature and relative humidity within crop were observed at periodic intervals under both the growing environments. Among micrometeorological parameters, PAR interception (76.3% in open and 56.2% under poplar plantation) and relative humidity (69.2% in open and 72.7% under poplar plantation) was maximum in 10th October sown crop, while canopy temperature (25.5ºС in open and 24.5ºС under poplar plantation) was maximum in 1st December sowing. The mustard variety (PBR-91) had highest white rust incidence (55%) in 1st December sowing, which was 10.0 per cent higher than the 5th November sown crop and 14.0 per cent higher than the 10th October sown crop in open condition. Similarly, Giriraj sown on 1st December had the highest white rust incidence (51%), which was 6.0 per cent higher than the 5th November sown crop and 16.0 per cent higher than the 10th October sown crop in open condition. Similarly, the crop sown on 1st December had the highest white rust incidence (50%) under poplar plantation, than the 5th November and 10th October sown crop. The grain yield was maximum (17.93 q/ha) in 10th October sowing followed by 5th November (16.27q/ha) and 1st December (13.77q/ha) sown crop under open conditions. Whereas, under poplar plantation, grain yield was comparatively lesser than open conditions. The grain yield was maximum (15.81q/ha) in 10th October sowing followed by 5th November (14.01q/ha) and 1st December (11.27q/ha) sown crop under poplar conditions. Among different varieties, PBR 91 gave higher grain yield under open and poplar conditions.
