Abstract

A field experiment was conducted at Horticulture Farm of Rajasthan College of Agriculture, Udaipur taking gladiolus (Gladiouls sp.) cv. White Prosperity as a test crop to find out the effect of organic manures and biofertilizers on yield parameters. The number of spikes, corms, cormlets, weight of corms and cormlets per plant increased significantly with the application of organic manures. Among the organic manures, vermicompost was found significantly superior over control with respect to yield parameters. The application of biofertilizers showed a perceptible improvement in yield attributing parameters of gladiolus. The highest number of spikes and corms per plant was observed with PSB (phosphorus solubilizing bacteria) followed by VAM (vesicular arbuscular mycorrhiza) and Azotobacter. A significant improvement was recorded in the weight of corms per plant with the application of biofertilizers and the highest weight was found with VAM. Interactive effect of organic manures and biofertilizers also found significant in case of number of spike, corms and cormlets per plant and highest values were recorded under PSB and vermicompost (T10).
