GROWTH AND P-NUTRITION RESPONSE OF LENTIL (LENS ESCULENTA M) GENOTYPES TO ARBUSCULAR MYCORRHIZAL FUNGAL INOCULATION AT DIFFERENT P-REGIMESS. Ngomle, B.S. Ambesh, T. Debbarma1 and B.N. Panja
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 soil were studied. Mycorrhizal inoculation (M) and phosphorus levels caused significant improvement of plant height, shoot-, root-, plantdry weight, P concentration and uptake studied of both genotypes except the root dry weight parameter of L-249 whereas and MxP caused significant enhancement in almost all parameters except root dry weight parameter of the genotype Asha. Mycorrhiza inoculated L-249 was found superior for all growth and P nutrition parameters to mycorrhiza 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 dry weight after 15 ppm, P concentration and uptake after 45 and root dry weight after 0 ppm decreased with increased levels of added P.
