Varietal response of white potato to fertilization under lowland conditions
Marcelo C Gutierrez Jr.
A study was conducted to determine the white potato variety best adapted to and the best NPK level for lowland conditions. The results showed that Isola significantly out grew the rest of varieties 30 days after emergence (DAE) but Cosima, Granola, Ilona, and Fina caught up 45 DAE, Linda was the tallest before vine cutting. The highest number of mainstems, which differed significantly from those taken from the rest of the varieties, were produced by Berolina, Franza, Monza, and Romanze. Greta, Ronea, Romanze and Ilona produced the highest number of lateral branches with Ilona producing the earliest. Fresh and dry weights of produce haulms significantly increased in Ronea and Romanze. Isola was most tolerant to insect pest infestations one week before vine killing.
