“…Plantas mais competitivas investem mais na produção de colmos e folhas e menos em grãos, portanto apresentam menor ICG. Correlação positiva do ICG com a produtividade de grãos de arroz irrigado foi relatada em diversos estudos (Fageria et al, 2007;Fageria et al, 2011;Fageria & Santos, 2015). Há evidências de que o ICG das culturas aumentou com a maior produtividade obtida nas últimas décadas.…”

“…This is in agreement with the findings of Malhi (1997) who reported that urea was less effective than AN for meadow bromegrass. Similarly, AS showed higher response than urea in rice (Fageria et al, 2011) that maybe associated with higher acidity producing capacity of AS compared with urea. The superiority of CAN compared to AS and urea in the present study maybe due to the immediate supply of NO 3 − to plants in early growth stages and then N will be available from NH 4 + sources.…”

“…Few studies had been reported previously on the comparative effects of different N fertilizer sources on the growth and yields of crops and response was generally inconsistent. Fageria et al (2011) conducted two greenhouse experiments on rice with urea and AS and reported that the maximum grain yield and N-uptake at average N rate (160 mg kg −1 ) was 22 and 15% higher with AS compared to urea. The comparative effects of urea and AN on meadow bromegrass (Bromus bibersteinii) at two sites in central Alberta, Canada indicated that AN generally produced higher DMY (16-26%), protein yield (21 and 37%), NUE (16 and 26%) and % N recovery (20 and 38%) compared with urea (Malhi, 1997).…”

“…Ao comparar fontes de N, Fageria et al (2011) verificaram que a maior produtividade de grãos foi associada com maiores biomassas da parte aérea e com os componentes da produtividade do arroz. Fageria et al (2008) obtiveram relação quadrática entre a BPA e a produtividade de grãos.…”
