Evaluation of yield and size distribution of seed potato tubers under different methods of phosphorus nutrition
In order to study the yield and size distribution of potato seed tubers under different methods of phosphorus (P) nutrition, a factorial experiment based on RCBD (Randomized Complete Block Design) with four replications was conducted in the spring 1391. Treatments included the amount of P fertilizer...

| description | In order to study the yield and size distribution of potato seed tubers under different methods of phosphorus (P) nutrition, a factorial experiment based on RCBD (Randomized Complete Block Design) with four replications was conducted in the spring 1391. Treatments included the amount of P fertilizer, source of P fertilizer and time of P application. Variables such as yield and its components, phonological, morphological and physiological traits were evaluated in potato plants. Results showed that strip application of P at planting stage caused an increase in Leaf Area Index (LAI). Petiole P concentration in potato plants was affected significantly by the interaction of source×amount×application time. The highest level of leaf nitrogen was shown in planting time use of en masse DAP. The minimum level of P fertilizer (37 kg/h net P) caused tuber number to significantly increase from 64.25 to 92.29. Seed tuber number (28-65) and seed tuber size in DAP treatment were significantly higher than two other fertilizer treatments. No-application (Control) treatment resulted in the lowest seed tuber in size and number. |
