Determination of optimal nitrogen rate for rice varieties using a chlorophyll meter

Site-specific N management (SSNM) such as real-time N management (RTNM) and fixed-time adjustable-dose N management (FTNM) improve fertilizer-N use efficiency of irrigated rice. This study was conducted to compare the N response and fertilizer-N use efficiency of Shanyou63 (SY63) and Liangyoupeijiu...
