Nitrogen Nutrition of Containerized Anemone x hybrida

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...

Phosphorus and Nitrogen Regulate Arbuscular Mycorrhizal Symbiosis in Petunia hybrida

Phosphorus and nitrogen are essential nutrient elements that are needed by plants in large amounts. The arbuscular mycorrhizal symbiosis between plants and soil fungi improves phosphorus and nitrogen acquisition under limiting conditions. On the other hand, these nutrients influence root colonization by mycorrhizal fungi and symbiotic functioning. This represents a feedback mechanism that allow...

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.

The Biology and Ecology of Rosa x hybrida (Rose)

Mineral nutrition and growth of containerized Pinus halepensis seedlings under controlled-release fertilizer

Low, moderate and high rates (3, 5 and 7 g/l, respectively) of two controlled-release fertilizer (CRF) types, Osmocote 9–13–18 and Osmocote 17–10–10 were evaluated for their effects on production of containerized Pinus halepensis planting stock. Both formulations had similar patterns of nutrient release, with high release rates during the first 2–3 months, in contrast with minimum seedling upta...
