A total of 7,707 agronomy papers (2006 to 2011) by Chinese, Indian, and Japanese authors were identified in the Web of Science (WoS) database. The impact factors (IFs) of papers and the uncited paper rate (UPR) in a particular journal with a given country's authorship was calculated as IFs calculated in Journal Citation Reports. For India, the impact factors of articles authored within one country (within-country impact factor) were significantly lower than the overall IF. The impact factors of collaborative articles (collaborative impact factor) and within-country impact factors for the three countries differed significantly. The uncited rates of collaborative papers (uncited collaborative paper rate) and uncited rates of papers authored within one country (uncited within-country paper rate) of China and Japan were significantly different. However, for India, the uncited collaborative paper rate was significantly lower than the uncited within-country paper rate; collaboration (mostly with developed countries) exerted a negative effect.
