Influence of biofertilizers on leaf nutrient status and flower quality of carnation cv Sunrise

The experiment was conducted under naturally ventilated polyhouse to study the influence of biofertilisers on leaf nutrient status and flower quality of carnation cv Sunrise. The plants were inoculated with biofertilizers arbuscular mycorrhiza + Azospirillum + phosphate solubilizing microorganisms and then fertigated with water soluble fertilizers. This treatment was compared with the plants which were only given water soluble fertilizers and commercial straight fertilizers. Significant variation was observed in leaf nutrient status as influenced by different fertilization treatments. Biofertilizers supplemented with water soluble fertilizer treatment resulted in maximum nitrogen, phosphorus and potassium content. Maximum stem length and stem sturdiness were recorded in the plants given biofertilizer treatment.
