CSH 6 to fertilizer P (0, 10, 20 and 40 kg/ha) on a Vertisol low in extractable P. One sorghum crop was grown each year during the rainy season (June to September). Tissue samples from the newest, fully-developed leaf were collected at 50% flowering stage to establish the relationship between leaf P concentration and grain yield. During the three years, sorghum grain yield and leaf P concentration increased in response to P application up to 40 kg/ha. Leaf P concentration was linearly related to grain yield (r² varied from 0.724 to 0.993). The critical leaf P concentration at 90% of the maximum grain yield was about 0.25% P. Phosphorus content in the grain was not significantly correlated to yield.","1999","published",,"Nutrient Cycling in Agroecosystems","54","1","Kluwer",,"93-98",,,,,,,,,,,"TRUE",,,,,,,,"","http://dx.doi.org/10.1023/A:1009780411676","http://scholar.google.co.in/scholar?as_q=Leaf+phosphorus+and+sorghum+yield+under+rainfed+cropping+of+a+Vertisol&num=10&btnG=Search+Scholar&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&as_sdt=1.&as_sdtp=on&as_sdtf=&as_sd","author",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
