Effects of different fertilizer treatments on yield and yield components of madder in saline conditions

This study was done to investigate the effects of urea and phosphate on madder in saline conditions at Research Farm of Isfahan Agricultural and Natural Resources Research Center located in the Rodasht city. A factorial experiment based on randomized complete block design with three replications was designed. Treatments consist of urea with 4 levels of zero, 50, 100 and 150 kg/ha and Triple Super Phosphate fertilizer with 4 levels of zero, 50, 100 and 150 kg/ha. Vegetative growth characteristics such as plant height, leaf dry weight, leaf area, panicle length and weight of 1000 fruits, biomass and root yield were measured. Analysis of variance in the third year, showed the effects of nitrogen and phosphorus fertilizer on plant growth characteristics of madder else the leaf area, panicle length and 1000 fruits weight was statistically significant. The highest yield of shoots was obtained due to application of 150 kg/ha urea and 150 kg/ha triple super phosphate as much as 1. 74 kg/m2. The highest yield of roots was obtained due to application of 100 kg/ha urea and 100 kg/ ha triple super phosphate as much as 0. 34 kg/m2. Totally, for obtaining the highest yield of madder in saline condition, we suggest the application of 150 kg/ha of urea and triple super phosphate.
