Abstract
This study were conducted at lath house / Hort . & Landscape Design/ Coll. of Agriculture and Forestry during 2010 and 2011 growing seasons on Tangarin transplants which were budded on sour orange rootstock to know the effect of autumn budding date (1/10/2010 and 15/10/2010) and foliar or soil application of structure fertilizer at two levels for each method (2 and 4 ml. L-1). The application of the fertilizer was done twice a season, with 20 days intervals, the first was done when the scion length was 45cm (at 15/4/2011). Results indicated that the first date of budding was dominated over the second date of budding in the leaves Zn level, transplants leave number, transplants leaves area, main stem length and diameter and lateral branches number. For the effect of method application and levels of structure fertilizer, results showed that soil application of the fertilizer at the level of 2 ml. L-1 gave the highest means of leaves N level, leaves dry weight, leaves area, transplant leaves area and main stem length, which were dominated over most other treatments. Meanwhile the heighest means of leaves chlorophyll, leaves fresh weight and leaves Zn level were in the treatment soil application of structure at 4 ml. L-1 level. In the case of the interaction between budding date and method and level of structure fertilizer, the best one was that between first budding date and soil application of the fertilizer at the level of 2 ml. L-1, which gave the highest means of leaves N and Zn levels, leaves dry weight, leaves dry weight percentage, leaves area, leaves number, transplants leaves area and main stem length.
