Application of industrial waste (silication) in red Argisoil of passion fruit cuttings - DOI: 10.4025/actasciagron.v26i4.1714

Abstract

This work aims to evaluate the effect of silication calcium and industrial waste application to the production substratum of passion fruit cuttings as corrective material in the development, in the production of dry matter and in the nutritional plant state. The experimental design used randomized blocks of 5 treatments and 4 repetitions. The silicate calcium doses were applied in half; once, once and a half; and twice the dose to increase the V = 50%. These doses corresponding to 0.18; 0.36; 0.54; 0.72g dm^-3, respectively. The cuttings received doses of N, P, K, Zn and B of 300; 450; 150; 5 and 0.5mg dm^-3 respectively. The experimental unit was constituted of 2dm³ vases of a red Argissol substratum. Thus, the stem diameter, height, leaf number, dry matter production of the airy part of the roots, as well as the macro and micronutrients were evaluated after 80 days of the plantation. Thus, the silicate application to yellow-red Argisoil samples promoted quadratic increment in the height, stem diameter and in production of dry matter of passion fruit. The largest changes development was associated to the improvement of the soil fertility (saturation for bases = 57%; Ca = 20mmol_c dm^-3) and in the nutritional plants state (Ca - dry matter = 7.4g kg^-1)
