Purple blotch disease has become a very serious disease of onion causing considerable yield loss in onion production. In the absence of resistant cultivars, management of Purple blotch disease has relied principally on application of synthetic fungicides. The present study evaluated the effects of fungicides on Purple blotch disease of onion and investigated the efficacy on yield of onion. The field experiment was laid in a randomized block design with five treatments and four replications in subtropical climatic condition of West Bengal at Regional Research Sub-Station (Red & Laterite Zone), Sekhampur, Birbhum, 731129, West Bengal, India during Rabi, 2020-21 and Rabi, 2021-22. The highest disease control was in Boscalid 26.7%+Pyraclostrobin 13.3% WG @ 1.0 g/litre of water (56.62%) followed by Metiram 55% + Pyraclostrobin 5% WG @ 1.0 g/litre of water (53.11%) and Azoxystrobin 18.2% w/w + Difenoconazole 11.4% w/w SC @ 1.0 ml/litre of water (48.05 %) at 15 days after 2nd spray. Maximum increase of marketable onion bulbs yield (67.98%) was obtained by the spray of Boscalid 26.7%+Pyraclostrobin 13.3% WG @ 1.0 g/litre of water as compared to other treatments

Late blight disease of tomato caused by Phytophthora infestans is one of the most destructive diseases which cause considerable loss in tomato production. In the absence of resistant cultivars, the management of tomato late blight disease has relied principally on the application of chemical fungicides. The present study evaluated the effects of chemical fungicides on tomato late blight disease and investigated the efficacy of the yield of tomato plants. The field experiment used a randomised block design, with five treatments and four replications in subtropical climatic condition of West Bengal at Regional Research Sub-Station (R & L Zone), Bidhan Chandra Krishi Viswavidyalaya, Sekhampur, Birbhum, West Bengal, India during Rabi, 2020-21 and Rabi, 2021-22. Three times foliar spray at an interval of 10 days with Cymoxanil 8% + Mancozeb 64% WP @ 3.0 g/litre of water was best followed by Famoxadone 16.6% + Cymoxanil 22.1% SC @ 2.0 ml/litre of water and Iprovalicarb 5.5% + Propineb 61.25% WP @ 2.0 g/litre of water. The findings of the present study demonstrated a promising approach of management of late blight disease of tomato with chemical fungicides

Information on the mutual association of traits is important for effective selection in plant breeding program. An experiment was conducted at R. B. S. College, Bichpuri, Agra to evaluate the direct and indirect effects of yield related traits on grain yield. Path coefficients were studied for twelve characters in six desired mutants of wheat. Days to 50% flowering, exerted high order of positive direct effects towards yield per plant followed by plant height at flag leaf stage and germination percentage. Days to germination made positive contribution towards yield per plant, spike length and weight of 500 seeds. This implies the true relationship between these traits and grain yield; therefore, due attention should be given on such traits during selection for further improvement
