Rice yields and yield gaps in Southeast Asia: Past trends and future outlook

Evaluating maize yield variability and gaps in two agroecologies in northern Ghana using a crop simulation model

“…The GM obtained with supplementary irrigation was, however, generally higher compared with the non-irrigated yield.

The potential yield of maize varied with time of sowing across all sites.…”

Identifying Factors Influencing Production and Rice Farming Income with Approach of Path Analysis

“…Rice productivity is highly correlated with production factors including seeds, fertilizers, pesticides and labor (Effendy, 2010;Li et al, 2008). Rice farming has faced challenges with stagnated overall production at a low level of 2000-5000 kg/ha (Fan et al, 2012;Mueller et al, 2012;Laborte et al, 2012;Ray et al, 2012;Grassini et al, 2013;Chen et al, 2014).…”

Drivers of spatial and temporal variation in soybean yield and irrigation requirements in the western US Corn Belt

“…A number of studies have assessed the sources of on-farm yield variation in sunflower (Mercau et al, 2001;Grassini et al, 2009), wheat (French and Schultz, 1984;Lobell et al, 2002;Calviño and Sadras, 2002;Sadras et al, 2002), rice (Laborte et al, 2012), cassava (Fermont et al, 2009), banana (Wairegi et al, 2010), and maize systems (Calviño et al, 2003a;Tittonell et al, 2008;Grassini et al, 2011a;Grassini et al, 2011b). Villamil et al (2012) investigated sources of field-to-field variation in rainfed soybean yields in Illinois (central US Corn Belt) using on-farm data but just from one growing season.…”
