[ 2 ] - تأثیر سطوح مختلف نیتروژن و پتاسیم مکمل محلول غذایی بر عملکرد و غلظت نیتروژن و پتاسیم برگ گوجهفرنگی
The effects of different levels of nitrogen (100, 200, 300 and 400 mg/L) and potassium (125, 250 and 375 mg/L) on yield and leaf N and K concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. The highest fruit yield was obtained with 200 mg/L N. Higher levels of nitrogen decreased tomato yield. With increasing nitrogen concentra...
