PRODUCED OF ROOTSTOCK OF RAUGPUR LIME, IN RESPONSE TO ORGANIC-MINERAL FERTILIZATION

The fertilization of substrate can provided high quality of raugpur lime tree rootstock. This work has the objective to evaluate the production of the raugpur lime tree rootstock (Citrus limonia Osbeck), in response to broadcasting application to organic-mineral fertilizer of substrate. The experiment was developed in a greenhouse conditions in pots filled with commercial substratum based on Pinus rind and turf. The completely randomized experimental design with 5 treatments and, 5 replications and 8 plants per pot was use. The treatments were doses (0; 0.5; 1.0; 1.5; 2.0 mL) of a dilute commercial fertilizer in 1 liter of water, being applied 5 mL in each pot weekly. Fertilizations started 70 days after sowing and 115 days evaluations were perfomed which consisted of plant height, leaf number, diameter stem, weight of the root and shoot dry matter and relationship between these. For the production of vigorous rangpur lime tree rootstock can be applied in brodcasting the substrate, a solution of 2.0 mL of organic mineral fertilizer.
