摘要

摘要本研究旨在评估库什蒂亚地区不同品种的假黑穗病发病率及其对产量的影响，并确定2018-2019年水稻生产的财务成本、收益和盈利能力。BRRI dhan49的5个严重程度等级中，平均产量损失最高(65%)的农民损失0.85 t/ha，而杂交品种Dhani Gold的产量损失最低(7%)，为0.20 t/ha。喷施Nativo (75 WG) 0.40 kg/ hm2比对照增产34.87%，在产量较Nativo低的地区施用Amister Top 325 SC。Tilt (250 EC) 0.45 l/ha和Folicur (0.90 l/ha)的产量也较未处理的对照区显著提高。BRRI dhan39总收益最高，为114753塔卡/ha，价格较高，品质优良。由于假黑穗病发病率较高，Shorna品种的总收益和净收益最低，分别为106958塔卡/公顷和- 1215塔卡/公顷。

Study on financial assessment of rice production causing false smut disease of different varieties at farm level in Kushtia district

Abstract The present study was conducted to evaluate the false smut incidence and its effect on yield in different varieties, and to determine the financial cost, return and profitability of rice production during the year 2018–2019 in Kushtia district. The highest average farmers (65%) lost their yield 0.85 t/ha in 5 severity scale of BRRI dhan49, while Dhani Gold as hybrid variety exerted the lowest yield losses of 0.20 t/ha in 7% affected farmers. Spraying of Nativo (75 WG) 0.40 kg/ha increased the yield 34.87% over control, and Amister Top 325 SC was applied in the field that produced lower yield compared to Nativo. Tilt (250 EC) 0.45 l/ha and Folicur 0.90 l/ha also showed significant increase of yield over untreated control plot. The highest gross return of BRRI dhan39 was determined at Tk. 114753/ha with higher price and its fine quality. The lowest gross return and net return were estimated at Tk. 106958/ha and (−) Tk. 1215/ha, respectively, in Shorna cultivar due to higher incidence of false smut disease.

期刊介绍： Archives of Phytopathology and Plant Protection publishes original papers and reviews covering all scientific aspects of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology, herbal studies and applied nematology and entomology as well as strategies and tactics of protecting crop plants and stocks of crop products against diseases. The journal provides a permanent forum for discussion of questions relating to the influence of plant protection measures on soil, water and air quality and on the fauna and flora, as well as to their interdependence in ecosystems of cultivated and neighbouring areas.
