Effect of planting season on the development of alternaria blight and head rot diseases of sunflower / R.C Prasai    

Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. II / Giri, Y.P.     Title : Effect of planting season on the development of alternaria blight and head rot diseases of sunflower Material Type: printed text Authors: R.C Prasai, Editor ; A Sah, Author ; G Parajuli, Author ; R.D Timila, Author Pagination: 347-352 p. Keywords: Disease  ;  resistant  sunflower  variety  yield Abstract: In order to fmd out the appropriate time of planting to escape sunflower from Alternaria blight (Alternaria helianthl) and head rot (Rhizopus sp.), Modem dwarf, SH-3322 & Hybrid Indam varities of the crop were sown in two consecutive seasons on Feb. 7, 17 & 27 during 2011 and on 8, 17 & 27 during 2012 spring. In winter season of20 II the crop was sown on Oct. 10, 20 & 30 in split plot design. Each variety and dates replicated thrice with a plot size 9 m2 at NORP. Severity of Alternaria blight found higher in spring season compared to winter season while head rot was found in moderate form in winter season. Modem dwarf planted in second week of February produced the highest yield (651, 460 & 556) kglha with highly significant treatment difference in the F.Y. 2010/11, 2011112 & in combination respectively. whereas Hybrid indam yielded 1587 kg!ha followed by Modem dwarf {1336 kg/ha) in second week of October with highly significant difference among the treatments. Therefore, planting f Modem dwarf in second week of February & October and Hybrid indam in second week of October could be recommended for the cultivation under farmers field condition.

Languages : English (eng) Keywords: Disease,  Pathogen  ,  Productivity,  Resistant,  Trichoderma Abstract: Alternaria blight caused by Alternaria brassicae is a major disease of rapeseed in Nepal so, an experiment was established at National Oilseed Research Programme in RCBD with eight treatments and each treatment replicated thrice including bio-agents and fungicide with control plot for two consecutive seasons 2008 and 2009. Among them, mixing of Trichoderma viridae @ 1Og/ kg well decomposed compost and incorporated in the soil at the rate of 10 ton/ha was found effective in controlling the disease appeared on leaves..................
