I. Gomez et al., SALINITY AND NITROGEN-FERTILIZATION AFFECTING THE MACRONUTRIENT CONTENT AND YIELD OF SWEET-PEPPER PLANTS, Journal of plant nutrition, 19(2), 1996, pp. 353-359
The effects of salinity due to sodium chloride (NaCl) and nitrogen (N)
concentration in the nutrient solution were studied with sweet pepper
plants. Four saline treatments combined with two N fertilization were
used. Nitrate-nitrogen (NO3--N) presence in the nutrient solution pro
duced an increase of sodium (Na) and potassium (K) contents in leaves
as well as N. Salinity promoted a reduction of K, phosphorus (P) and C
a and increased the Na concentration in leaves. Calcium (Ca) concentra
tions were lower in the higher NO3(-)-N treatment although N level was
reached adding calcium nitrate and salinity increased P, K, Na, Ca, a
nd magnesium (Mg) contents in fruits. Yield was increased in the highe
st N treatment.
