Abstract
Generally K-deficiency decreased all the growth parameters, root and shoots K-uptake, root and shoot K-concentration and potassium use efficiency (KUE). However, comparatively less relative reduction (%) or potassium stress factor (KSF) was observed in most of the growth parameters in the genotypes NIA-8/7, NIA-MB-I, SD-4085/3 and SD-4047. Absolute growth rate (g day) and relative growth rate (g gday) was increased by 19 % under K-deficient environment in the genotype SD-4085/3, whereas comparatively less relative reduction was exhibited in the RGR in the genotypes NIA-8/7 (11 %), SD-4047 (14 %), SD502 (8 %). Root dry weight showed 8.20% increase in the genotype 22-03 under K-deficient environment, whereas no relative reduction was found in the genotype SD-4085/3 and SD-502 under the same environment (K-deficient). The genotypes NIA-8/7 and SD-4085/3 exhibited 2.89 and 26.69% increase, respectively in the shoot dry weight under K-deficient environment. Among all the nine genotypes evaluated in this study, increase in root potassium uptake under Kdeficient environment was found in the genotype 22-03 (27%), whereas comparatively less relative reduction was observed in the genotype SD-4085/3 (6%). The genotype SD-4047 exhibited less relative reduction (8.9%) in the shoot potassium uptake. In conclusion the genotypes NIA-8/7 (0.32 g SDW mg shoot K), NIA-MB-I (0.2703 g SDW mg shoot K), SD-4085/3 (0.2987 g SDW mg shoot K) and SD-4047 (0.2567 g SDW mg shoot K) had higher potassium use efficiency among all the genotypes evaluated. It was concluded from this study that wheat genotypes differ in growth response and potassium use efficiency (KUE) when grown at deficient and adequate K-level.
