Early transplanting of rainfed rice minimizes irrigation demand by utilizing rainfall

Abstract: Background Rainfall is the key contributor to provide soil moisture for wet season rice (T. Aman) cultivation. Erratic rainfall often causes water shortage resulting negative impact on plant growth and grain yield. The study aimed to determine suitable transplanting window that utilize maximum rainfall for T. Aman rice. Firstly, three years field experiment were conducted in Kushtia, Bangladesh from T. Aman, 2013 to 2015, and then the findings were implemented for another two adjacent locations… Show more

“…This supports our hypothesis that irrigation scheduling at lower SMPs during the vegetative phase, coinciding with the rainy season, may help in more productive utilization of precipitation and reduced groundwater withdrawal for irrigation. The results also confirm the observation that early transplanting of rice reduces the irrigation amount by utilizing rainfall in the vegetative period in Bangladesh (Hossain et al, 2021). Our results also reveal that even the highest water‐requiring ZT1 among ZTDSR treatments needed approximately 16% less irrigation water compared to PTR.…”

“…Average annual rainfall of Rangpur is 2,200 mm and 80% of which occurs during the monsoon (June to October) period. In Pabna region, the average high and low temperatures are 31.2 °C and 20.8 °C, respectively, having average annual rainfall 1,603 mm (Hossain et al, 2021b). The topography in both the locations is medium highland to highland.…”
