A very little research work has been done on spider lily for standardization of agro techniques like planting, manuring, irrigation, spacing, nutrition, harvesting and post-harvest handling etc. Some standardize techniques are available for common cultivation of spider lily in starting year, but nobody has worked for optimum requirement of nutrients in ratoon crop of spider lily.Hence there is a need to find out the effect of nitrogen, phosphorus and potash on growth, flower yield and bulb. Это и многое другое вы найдете в книге Spider Lily: Prospectus to It’s Macronutrients Application & Yield (Kejakar Pradip and Polara Nitesh)
