Effects of 42-year long-term fertilizer management on soil phosphorus availability, fractionation, adsorption-desorption isotherm and plant uptake in flooded tropical rice (2015, neutral): “[26] in a rice–wheat cropping system.”
Nutrient Uptake and Apparent Balances for Rice-Wheat Sequences. III. Potassium (2006, background): “Based on 33 LTEs with RW systems in South Asia and China, Ladha et al. (2003) concluded that significant declines of rice and wheat yields were associated with large negative balances (−9 to −175 kg ha−1) of K.”
Satellite detection of earlier wheat sowing in India and implications for yield trends (2013, background): “However, concerns have mounted over the past decade that wheat yields have stopped rising in experimental trials (Ladha et al., 2003) and in farmers’ fields (Chatrath et al., 2007; Lin and Huybers, 2012).”
Long-term effects of inorganic fertilizer and farmyard manure application on productivity, sustainability and profitability of rice-wheat system in Mollisols (2018, background): “During green revolution era, increased production was not only due to the expanded area for both rice and wheat but also due to increased system productivity (Ladha et al. 2003).”
Productivity and sustainability of the rice-wheat cropping system in the indo-gangetic plains of the Indian subcontinent: Problems, opportunities, and strategies (2012, background): “…in fuel, labor, and irrigation water, early sowing of wheat, positive effects on soil health, better quality of environment, lower weed (P. minor in wheat) infestation, reduced lodging, etc., have been documented (Gupta et al., 2005; Khan et al., 2001; Ladha et al., 2003; Malik et al., 2005a).”
