Abstract

Planting density and weight of minituber are the factors influencing on the yield and yield components on seed tuber production in potato. In order to study the effect of distance and the weight of minituber on quantity and quality traits of seed tubers of potato cv. Savalan, the experiment was designed as a factorial experiment in randomized complete block design with three replications. In this research, minitubers with five different weights (20 g) in three intra rows spacing of 15, 20 and 25 cm and 75 cm inter row spacing were studied. The number of tuber in 1 m2, weight and number of tuber in each plant, total yield, the percentage of tubers with the size 55 mm and tubers diameter were recorded. Results showed that the effect of distance and minituber weight on the average of number of tuber per m2, weight and number of tuber in each plant and the total yield were statistically significant (p≤0.01). In this study, other traits such as the percentage of tubers with the size 20 g compared to cultivation of minitubers 20 gram with 15 cm within-rows spacing. In this research, tuber yield showed a positive and significant correlation with weight and number of tuber in each plant and tuber diameter. So that for achivement of the greatest yield indexes of Savalan cultivar in Mashhad climate conditions, caltivation of minitubers >20 g with 15 cm within-rows spacing is recommended.
