Growth and productivity of some potato (Solanum tuberosum L.) varieties grown under local conditions

Abstract

This experiment was conducted to evaluate growth and production of four imported potato varieties namely Spunta, Faluka, Sinora and Erika under local conditions. Results showed significant differences between varieties in some growth parameters. Erika gave a large leaf area (221 cm²) compared with other varieties, while Faluka and Spunta produced the highest plants (37.3 and 35.3 cm), compared with other varieties. Faluka was superior in number of stems/plant averaged 2.2 stems/plant compared with other varieties, with no significant differences among other varieties in this parameter. Regarding average foliage fresh and dry weight, Faluka was the highest in this trait (276.4, 25.4 gm.), while other varieties did not show any significant differences. Faluka achieved the highest average yield (977 gm. /plant), whileSinora had the lowest yield (490 gm. /plant). Faluka showed its superiority in number of tuber /plant (8.6 tuber/plant) compared with other varieties, while Spunta gave the highest tuber average weight (130.7 gm.) and Sinora gave the lowest tuber average weight (92.4 gm.).Results showed significant differences between varieties in number of large tuber size (> 60 mm), small and medium tuber size (30-60 mm) produced under this conditions.
