OAR@ICRISATIntercepted radiation as a tool to document plant population effects on leaf area and dry matter in sorghum (Sorghum bicolor)E AElashaauthorF RBidingerauthorB BReddyauthorA field trial was conducted during the rainy season of 1995 at Patancheru, Andhra Pradesh, India to compare weekly estimates of photosynthetically active radiation interception, to changes in leaf area and total crop biomass between 25 and 60 days after emergence in sorghum crop sown at 4 different plant populations (2.5, 5.0, 10.0 and 20.0 plants/m2). The weekly radiation interception measurements effectively differentiated the 4 plant population treatments, both directly and in terms of predicted leaf area and biomass, as the relationships of radiation interception to leaf area and biomass were constant across treatments and time. In general, radiation interception, leaf area index and total biomass, were higher with the higher plant populations (10.0 and 20.0 plants/m2) than the 2 lower populations (2.5 and 5.0 plants/m2). Thus, ceptometer measurements of light interception provided an accurate and inexpensive way o estimating crop growth differences in sorghum.Sorghum2001Article
