Growth and P-Nutrition Response of Lentil (Lens Esculenta M) Genotypes to Arbuscular Mycorrhizal Fungal Inoculation at Different P-Regimes

Abstract

Interaction of mycorrhizal inoculation (M) and phosphorus levels (P) on two lentil genotypes Asha (with high root hairs) and L-249 (with no root hairs) in low nutrient soil red-laterite oil were studied. Mycorrhizal inoculation (M) and phosphorus levels caused significant improvement of plant height, shoot-, root-, planty weight, P concentration and uptake studied of both genotypes except the root y weight parameter of L-249 whereas and MxP caused significant enhancement in almost all parameters except root y weight parameter of the genotype Asha. Mycorrhiza inoculated L-249 was found superior for all growth and P nutrition parameters to rnycorrhiza inoculated Asha at zero level of P. The former showed decreasing trend for all parameters with added levels of P but in latter plant height after 30 ppm, shoot and plant y weight after 15 ppm, P concentration and uptake after 45 and root y weight after O ppm decreased with increased levels of added P.
