Biomass and harvest index as indicators of nitrogen uptake and translocation to the grain in sorghum genotypes uri icon

abstract

  • Nitrogen is usually the most limiting nutrient for crop production and the poor recovery of applied fertilizer nitrogen by crops is of world wide concern. The differential response of sorghum (Sorghum hivolor L. Moench) genotypes lo applied nitrogen suggests that differences in nitrogen uptake, translocation and accumulation in the grain exist1. This paper deals with (i) the extent of variation in sorghum for the above characters, (ii) correlations of these traits with agronomic traits such as days to flower, biomass and grain yield and, (iii) the implications of (i) and (ii) in breeding and crop management
