Response of saffron to industrial particulate pollution under soil amendments with biofertilizers: changes in physio-morphological, yield and soil characteristics
The study carried out for two consecutive growth years, each year for a period of 7 months (September-April) has revealed that cement dust affected plants amended with Pseudomonas sp. show a slight lesser reduction in the photosynthetic pigments, N, P and K, carbohydrate, ascorbic acid contents as well as phytomass and length of leaves compared to the plots amended with Azospirillum sp. and Azotobacter sp. However proline contents of the foliage exhibited increased levels in the same environmental set-up. The yield of saffron (kg ha-1) and various morphological characters of the flowers viz., size of perianth, length and biomass of the pistil and stigma (saffron of commerce) as well as the whole flower also suffered comparatively lower losses in the plots amended with Pseudomonas sp. than other two biofertilizers. The effect of dust was less adverse on the plants raised in biofertilizer amended soils and highest in the plots which were not amended with any biofertilizers. Analysis of the soil has revealed that except available N all other parameters viz. pH, EC, available P and K, Exchangeable Ca and Mg recorded higher values in the biofertilizer amended soils compared to control.
