      abstract = {Results of a collaborative project involving over 28  agronomists and economists
are reported. Over 800 agronomic  experiments conducted in ten locations in six
Asian  countries comparing farmers' production with maximum yield  levels of
modern rice technology are analysed. Under wet  season conditions, yields were
raised by an average of 0.9  tonnes per hectare, but the cost of obtaining the
increased  yields exceeded their value in six out of ten locations.  Under dry
season conditions, yields were increased by an  average of 1.3 tonnes per hectare,
and were profitable in  nine out of ten locations. High levels of fertilizer  and
insect control contributed roughly equally to raising  the yields, but the increased
cost of high insect control  exceeded the value of its yield contribution in most
cases.  The opposite was generally true for fertilizer. One result  has been that
rice entomologists have reoriented their  research to try and achieve more cost
effective protection.  There was a distinct negative correlation between  the
increased yield obtained by adding fertilizer above the  farmers' levels and the
price of fertilizer in terms of  rice, dramatizing how price policies affect
incentives.},
