A relationship between the relative growth rate and nutrient uptake rate of different varieties of C. capsularis and C. olitorius and their fibre yield potentiality were studied. The relations between growth rate of shoot and nutrient uptake (N, K and Ca) were lower at 45 days after sowing which became higher (2-3:1) at the stage nearing maturity (106 days). But in the case of P. the ratio was more or less equal and paralleled the growth rate till maturity. The fibre yield potential of JRC-321, JRC-212, JRO-620 and JRO-878 may be expressed more fully at a higher level of fertility whereas D -145 JRO-524, JRO-36E and JRO-7835 may be grown on soils of moderate fertility without the risk of losing their full yield potential. Differential behaviour pattern of nutrient uptake varied at different growth stages. It has thus been suggested that the proper time of application of fertilizer be made to coincide with the period of maximum demand of the species or the variety for the nutrient concerned.
