| dc.description | Due to widespread deficiency of phosphorus in acid soils in various parts; of the world, germplasrn screening for identification of less susceptible cultivars of crop plants has become as essential as recommendation of proper methods and levels of P fertilization. To study the relationship between differential susceptibilíty to P deficiency, four cultivars of rice (Oryza sativa L.) were grown in nutrient solution at 8.06, 32.25, 322.58 gM (0.25, 1 and 10 ~LgP.m1-1) of applied P. After 54 days of growth in nutrient solution, dry matter yield of roots and shoots and P and K uptake were measured. Rice cultivars did not differ widely in dry matter production and P uptake. Among the growth parameters, shoot dry weight was the best parameter for classifying cultivars as to P efficiency. Based on this parameter, cultivars were classified for P efficiency in the order: IRAT 104 > Beira Campo > Bico Torto > Quatro Meses. Phosphorus uptake was increased with increasing concentrations of P in the growth medium. This study suggests that this methodology can be used for identification of P efficient rice cultivars. | |
