BATISTA CAMPOS, Vinícius et al. Liquid bovine manure in luvissol sodic: Biometric and productive response of yellow passion fruit plants. Idesia [online]. 2011, vol.29, n.2, pp.59-67. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292011000200008.

ABSTRACT  The objective of the present study was to evaluate the effect of liquid bovine biofertilizer on the biometry and the dry matter production of yellow passion fruit seedlings grown on sodic Luvissol. The experiment was performed in the Department of Soil and Rural Agricultural Engineering of the Center of Agricultural Sciences (CCA), Federal University of Paraíba (UFPB), from August to October 2008. The experimental design was that of randomized blocks in split plots, where the plots were the levels of liquid biofertilizer at 0, 25, 50, 75 and 100% by volume of 10% of the total substratum volume (250 mL), the subplots were the five plant evaluation periods (45, 60, 75, 90 and 105 days after the sowing); the experiment was performed in quadruplicate. The application of biofertilizer was made 30 days before sowing, followed by a washing of the soil (two days after of biofertilizer application); a second application of the biofertilizer was made 48 hours before sowing, followed by a soil washing similar to that of the first application. Non-saline water was used for irrigation, adding the water equivalent to the evapotranspiration rate per 24 hours, based on weighing the pots. The increased level of organic matter input provided greater plant height and stem diameter, as well as greater leaf number, foliar area and total dry matter, surpassing the control by 134.78; 114.72; 127.35; 416.54 and 107.97%, respectively.

Palabras clave : Passiflora edulis Sims; bovine biofertilizer; dry matter; sodicity.
