[ 1 ] - توزیع فسفر و روی در اندام‌ها و مراحل رشد گندم در گلخانه و ارتباط آنها با این عناصر در خاک
The effect of phosphorus (P) (0, 25, and 50 mg kg-1 soil as Ca(H2PO4)2) and organic matter (OM) (0, and 2% w/w feedlot cattle manure) on P and zinc (Zn) distribution in different parts of wheat plant (Triticum aestivum L.) at various growth stages and its relationship with soil P and Zn were determined in greenhouse condition. In all pots, shoot P concentration decreased as plant growth proceed...
[ 2 ] - اثر فسفر و ماده آلی بر روابط فسفر خاک- گیاه در اسفناج
To determine the effect of application of phosphorus (P) and organic matter on soil-plant P relationship at different growth stages of spinach, an experiment was conducted at greenhouse conditions. Treatments consisted of two levels of organic matter (0 and 2% of sheep manure) and three levels of P as Ca(H2PO4)2 (0, 20 and 60 mg P kg-1soil). Soil and plant samples were collected at five growth...
[ 3 ] - اثر شوری و نیتروژن بر توزیع عناصر غذایی، اسید سیتریک و ویتامین C در گوجه‌فرنگی
The effect of salinity and nitrogen on yield, vitamin C, citric acid and nutrient distribution of tomato in hydroponics culture was investigated. Tomato seeds were first let germinate in yonolit pots with wet coco peat and then their seedlings were transferred to plastic tanks containing 5 liters nutrient solution. Treatments were three levels of salinity (0, 30 and 60 mM as NaCl and CaCl2) and...
[ 4 ] - تأثیر سطوح شوری و نیتروژن بر رشد، عملکرد و جذب عناصر غذایی گوجه‌فرنگی تحت شرایط آبکشت
This experiment was conducted to determine the effect of salinity and nitrogen on growth and yield of tomato and concentration and total uptake of some nutrients in different parts of plant in hydroponics culture. Nitrogen (N) was used at 0, 1.5 and 3% levels as NH4Cl and NH4H2PO4 and salinity consisted of 0, 30 and 60 mM as NaCl and CaCl2 (2:1 w/w). A completely randomized design experiment wa...
