PHOSPHATE AND POTASSIC FERTILIZATION ON SEEDLING PRODUCTION OF TAMARIND FRUIT

Abstract

The knowledge of the fertilization practices on fruit propagation is important in order to obtain well formatted seedlings which will warranty the success on implementation and high productivity of the orchards. However the researches with this species it is quite a few yet, especially on seedling production. The present work aimed to evaluated the effects of potassic and phosphate fertilization on seedling development of tamarind fruit Tamarindus indica,L. The experiment was carried out in 50% luminosity greenhouse, and the experimental design adopted was randomized block in a factorial scheme 4x4: 4 doses of P 0, 150, 300 e 600 kg m^-3 of simple super phosphate and 4 doses of K 0, 75, 150 e 300 kg.m^-3 of KCl. One hundred and twenty days after germination the seedling were evaluated by the following characteristics: length of aerial and root part, number of leaves, dry weight mass of root and aerial part. It is recommended the application of potassium chloride at 3 kg m^-3 to increase aerial part and single super phosphate at 5 kg m^-3 for root length and number of leaves.
