THE NITROGEN NUTRITION OF GREEN PLANTS

Nitrogen Nutrition of Containerized Thuja x ‘Green Giant’1

Rooted stem cuttings of ‘Green Giant’ arborvitae (Thuja L. x ‘Green Giant’) were grown in 3.8 liter (#1) plastic containers containing a pine bark:sand (8:1 by vol) substrate. Plants were fertilized three times weekly for 15 weeks with a complete nutrient solution at N application rates (NARs) of 0, 10, 20, 40, 80, 160, or 320 mg/liter (ppm) supplied as ammonium nitrate (NH 4 NO 3 ). Both shoot...

Application of Medicinal Plants in Poultry Nutrition

Application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. Therefore, scientists are searching for alternatives to antibiotics nowadays. Medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. In this paper, the benefits of...

Nitrogen Nutrition of the Pineapple Plant ,

Unpublished studies in the files of the Pineapple Research Institute of Hawaii indicate that under present cultural conditions the .pineapp1e plant displays superior performance with a foliar applied combination of ammonium and nitrate nitrogen than with either form of nitrogen alone. The studies presented here were undertaken to evaluate ammonium nitrate as a nitrogen source under different so...

Nitrogen Nutrition in Rice

Nitrogen nutrition in rice though widely discussed, still modern concepts and findings are enriching us. It is also a difficult concept due to large variability of cultivation practices and environment. A clear idea of nitrogen nutrition will not only enhance productivity but also the nitrogen use efficiency. These concepts will be elaborated hereunder.
