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.
