Tree Spacing and Rootstock Affect Growth, Yield, Fruit Quality, and Freeze Damage of Young 'hamlin' and 'valencia' Orange Trees
A citrus spacing experiment begun in 1980 included 4 spacings, 2 varieties, and 2 rootstocks. Planting densities ranged from 150 to 360 trees per acre with spacings from 8 x 15 ft to 15 x 20 ft. 'Hamlin' and 'Valencia' Sweet orange (Citrus sinensis (L.) Osb.) trees were planted on Milam lemon ( C. jambhiri Lush) and Rusk citrange ( Poncirus trifoliata (l.) Raf. x C. sinensis) rootstocks. Trees ...

متن کاملIncorporating Controlled - Release Fertilizer Technology into Outplanting
The application of controlled-release fertilizers (CRF) at the time of planting offers a means to improve the establishment of forest tree seedlings. As compared to conventional fertilizers, the gradual pattern of nutrient release from CRF may better coincide with plant needs, minimize leaching, and improve fertilizer use efficiency. Many different CRF types are available and products differ in...
متن کاملToxicity and Accumulation of Salts in Citrus Trees on Various Rootstocks in Texas
years. Fertilizing once in the spring with a complete fertilizer with Uramite as the nitrogen source was satisfactory. On Lakeland soil Valencia and Hamlin orange tree growth was very good when about 1, 2, and 4 pounds of 8-2-8 inorganic fertilizer was applied in the first, second, and third seasons, respectively. Timing of applications of fertilizer also was not critical for young Valencia or ...
متن کاملControlled Release Fertilizer Improves Quality of Container Longleaf Pine Seedlings
In an operational trial, increasing the amount of nitrogen (N) applied to container longleaf pine seedlings by incorporating controlled release fertilizer (CRF) into the media improved seedling growth and quality. Compared with control seedlings that received 40 mg N, seedlings receiving 66 mg N through CRF supplemented with liquid fertilizer had needles that were 4 in (10 cm) longer as well as...
