SUBSTRATE MIXING FORMULATIONS FOR CITRUS NURSERY MANAGEMENT

The length of citrus seedling development is determined by several factors, including the physical and chemical qualities substrate, which affect rootstock growth and, as a result, quality field seedlings. purpose this study was to see how ‘Swingle’ citrumelo developed with different substrate formulations. experiment carried out in nursery from seeding grafting, six treatments were out, follows: 60% peat moss, 30% fine grade horticultural vermiculite, 10% rice hulls (1); (2); 50% 20% (3); (4); (5); (6). In addition, divided into two stages: (stage 1) 2). completely randomized design, has treatments, four replications, 51 plants per plot. When container transplanting performed, emergence percentage seedlings determined; thus, eight plot examined. For second stage, used design 6 formulations, 4 20 Stem height, stem diameter, leaf number, area meter, root dry matter, index measured on every 28 days. All formulations improved until except for hulls, hampered ‘Swingle' citrumelo.
