Research was conducted to evaluate the effects of cyclic irrigation on irrigation efficiency, nutrient efficacy, and plant growth in a simulated nursery and included 4 irrigation treatments: 900 ml of water applied once a day, 450 ml applied in two cycles, 300 ml applied in three cycles, and 150 ml applied in six cycles. A cycle consisted of a one hour rest interval between each irrigation allotment. Cycled irrigation improved irrigation efficiency and Subjects--Topical Terms:

520 $a Research was conducted to evaluate the effects of cyclic irrigation on irrigation efficiency, nutrient efficacy, and plant growth in a simulated nursery and included 4 irrigation treatments: 900 ml of water applied once a day, 450 ml applied in two cycles, 300 ml applied in three cycles, and 150 ml applied in six cycles. A cycle consisted of a one hour rest interval between each irrigation allotment. Cycled irrigation improved irrigation efficiency and $\ rm NH\sb4 $ efficacy in the containerized plant production system used in this experiment.
520 $a The effects of reduced leaching fraction via cyclic irrigation in combination with reduced fertilizer rates on irrigation efficiency, nutrient efficacy, and plant growth were considered. Cumulative volume applied to and leached from a container, and $\ rm NO\sb3,\ NH\sb4, $ and P contents in effluent were decreased with low leaching fraction.
520 $a Nitrogen release patterns of three composts under simulated temperatures found in container substrates were quantified. Temperatures found in container substrates resulted in greater total inorganic N mineralized from composted turkey litter compared to temperatures typically found in soils.
520 $a The effects of N form and ratio on root anatomy and growth of roots and shoots of Cotoneaster dammeri 'Skogholm' and Rudbeckia fulgida 'Goldsturm' were evaluated. The 0:100 $\ rm NH\sb4:NO\sb3 $ resulted in lower leaf, stem, and root dry weights and lower leaf area of cotoneaster than either 100:0, 50:50, or 25:75 $\ rm NH\sb4:NO\sb3. $ Rudbeckia fertilized with 0:100 $\ rm NH\sb4:NO\sb3, $ produced lower leaf and root dry weights and had smaller leaves than rudbeckia fertilized with any other ratio. Diameter of root steles of cotoneaster and rudbeckia and number and size of secondary tracheary elements increased when exposed to 25:75 $\ rm NH\sb4:NO\sb3 $ compared to 0:100 $\ rm NH\sb4:NO\sb3.
