Agricultural potential of organic compost produced based on sisal residue, manure and rock flour in the production of sisal seedlings

Abstract

Sisal is a great socio-economic importance of culture in Bahia, however, still little studied, becoming necessary studies that show alternative technologies for the production of seedlings with good plant health and nutritional quality. The use of the shredding of the leaves generated waste is a viable alternative for fertilization of crops. This study evaluated the agricultural potential of a compound produced with different proportions of sisal waste, rock flour and manure on growth and nutrition of sisal seedlings. The experiment was conducted in randomized block design in factorial design 2 x 5 x 5, 2 soils, 5 organic compounds and 5 doses (0, 10, 20, 30 and 50 t ha^-1), with four replications. Unable to define the optimal dose to be applied from organo compounds, however, generally, these were superior to the control (zero dose without applying organic-compound) to promote improvement in nutritional sisal seedlings. The compound C5 with manure 30% + 30% + rock flour 40% sisal residue led to significant increases in plant height (38.9% and 45%), diameter (15.6% and 61.1%) and biomass production (50% and 78%) respectively in sisal seedlings grown in a clay soil and sandy, respectively.  Factors such as type and degree of soil fertility, plant vegetative cycle, as well as material to be used should be considered in the preparation of the organic compound.
