Effect of foliar fertilizer (high in potash)‎ on growth and yield of seven potato cultivars (Solanum tuberosom L.)‎

الملخص EN

An experiment was conducted out during 2009 to study the effect of spraying numbers (0, 2 and 4) of Alaska foliar fertilizer (N : 12, P2O5 : 12, K2O : 36, Fe : 0.05 %, Cu : 0.005 %, Mn : 0.03 %, Zn : 0.01 %, B : 0.02 % , Mo : 0.003 %) on growth and yield of 7 potato cvs.

(Draga, Aladin, Elpaso, Kurado, Diseree, Provento, and Red Brown).

Factorial experiment included 21 treatments arranged in Random Complete Bloke Design (RCBD) with 4 replications.

Results showed that foliar fertilizer had a significant effect on plant height, tuber weight and total yield.

Potato cvs differ in all studied parameters.

High yields were obtained from Red Brown, Provento and Draga cvs.

Interactions had a significant effect on the most studied parameters.
