Growth and Productivity of Two Cabbage Cultivars Grown in Sandy Soil as Affected by Foliar Spray with Npk Fertilizer and Amino Acids

The present work was carried out at Private Farm (The Experimental Farm of Sand Valley Company) at Ismailia, Ismailia Governorate, Egypt during 2017 / 2018 and 2018 / 2019 seasons to study the effect of foliar spray with NPK (15-15-15) fertilizer at 1 or 2 ml/l and amino acids at 1.5 or 3 ml/l  on two cabbage  cultivars (OS Cross and  Landini )   grown under sandy soil conditions.The interaction between  OS Cross cultivar and spraying with amino acids at  3 ml/l and  NPK  (15-15-15) fertilizer at 2 ml / l  increased   fresh weight of roots  and stem, number of leaves / head and fresh  weight of outer and inner leaves / head  ,head yield/ plant , total head yield/ fed .and head diameter and circumference  , followed by the interaction between  OS Cross cultivar and spraying with amino acids at  1.5 ml/l and  NPK  (15-15-15) fertilizer at 1 ml / l with no significant differences with the interaction between  Landini cultivar and spraying with amino acids at  3 ml/l and  NPK  (15-15-15) fertilizer at 2 ml / l with respect to number of leaves / head.
