Effects of calcium nitrate and humic acid on pepper seedling growth under saline condition.

Abstract

This study was carried out in order to determine effects of calcium nitrate and humic acid applications on pepper seedling growth under saline condition. A mixture of soil:sand (1:1) was used as a plant growing media including 90 mg kg -1 P 2 O 5 , 180 mg kg -1 K 2 O and 250 mg kg -1 N. Four different doses of humic acid (0, 1000, 2000 and 4000 mg kg -1 ) and calcium nitrate (0, 50, 100 and 150 mg kg -1 ) were applied into the growing media. Before sowing Demre variety pepper seeds, 60 m mol NaCl was added into 300 cm 3
