Abstract

A study was undertaken to evaluate the impact of soil application of spent mushroom substrate (SMS) and farm yard manure (FYM) enriched with T. harzianum on pre-emergency damping off (PED) and post-emergence damping off (POED) in chilli and tomato seedlings in nursery beds containing naturally infested soil with Pythium aphanidermatum and Rhizoctonia solani in the experimental field area of Department of Plant Pathology, CCSHAU Hisar during 2018-19, 2019-20and 2020-21.The observations on disease incidence (%) were recorded up to 30 days after germination. A control without soil amendment was also maintained. The maximum damping off was at 22.5, 23.4 and 22.9% in controland minimum at 15.7, 15.8 and 16.6% during 2018–19, 2019–20, 2020–21, respectively in chilliwhen SMS enriched with T. harzianum was applied. The mean of damping off disease incidence was minimum at 16.0% when SMS enriched with T. harzianum was applied and maximum at 22.9% in control. The maximum damping off was at 18.1, 19.4 and 18.7% in control and minimum at 12.2, 12.6 and 14.8% during 2018–19, 2019–20, 2020–21, respectively in tomato when SMS enriched with T. harzianum was applied. The mean of disease incidence (%) was minimum at 13.2% when SMS enriched with T. harzianum was applied and maximum at 18.7% in control.

播期和养分管理对小麦生理参数的影响

在2018- 2019年、2019- 2020年和2020- 2021年，在中国农业大学植物病理学研究所试验田，在含有天然蛀皮霉和枯丝核菌侵染土壤的苗床上，研究了在土壤中施用富含哈兹安菌的废菌基质(SMS)和农场厩肥(FYM)对辣椒和番茄幼苗紧急前阻尼(PED)和出苗期阻尼(POED)的影响。在萌发后30天内记录病害发生率(%)。保持不进行土壤改良剂的对照。2018-19年、2019-20年、2020-21年期间，施加哈氏霉富菌SMS对辣椒的最大减振率分别为22.5%、23.4和22.9%，最小减振率分别为15.7%、15.8%和16.6%。施用富含哈兹菌的SMS时，平均减病率最低，为16.0%，对照组最高，为22.9%。在2018-19年、2019-20年和2020-21年期间，施用富哈兹兰菌的对照番茄的最大减振率分别为18.1%、19.4%和18.7%，最小减振率分别为12.2、12.6%和14.8%。施用富含哈兹菌的SMS时，平均发病率(%)最低为13.2%，对照组最高为18.7%。
