The CPR allows productivity, intercepted radiation and seasonal transpiration to be compared so that conversion coefficients for radiation (e; g MJ−1) and dry matter/water ratios (q; g kg−1) can be calculated for each intercrop component and its constituent sole crops. In this experiment, CPR for total dry weight in the intercrop was 1.08 and that for reproductive yield was 1.27. These advantages in overall productivity and yield were typical of those reported elsewhere for sorghum/groundnut intercrops. The proportional increase in total dry matter in the intercrop was largely a result of its greater interception of radiation. The further advantage in reproductive yield was a consequence of an improved harvest index in the sorghum component of the intercrop (0.64) compared with that of its sole crop counterpart (0.55). date: 1990 date_type: published publication: Experimental Agriculture volume: 26 number: 4 publisher: Cambridge University Press pagerange: 413-427 refereed: TRUE issn: 1469-4441 official_url: http://dx.doi.org/10.1017/S0014479700001344 related_url_url: http://scholar.google.co.in/scholar?as_q=Light+Use%2C+Water+Uptake+And+Performance+of+Individual+Components+of+a+Sorghum%2FGroundnut+Intercrop&num=10&btnG=Search+Scholar&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&as_s related_url_type: author citation: Azam-Ali, S N and Matthews, R B and Williams, J H and Peacock, J M (1990) Light Use, Water Uptake and Performance of Individual Components of a Sorghum/Groundnut Intercrop.
