Growth, production and nutrients in coriander cultivated with biofertilizer

Abstract

The aim of this study was to evaluate the effect of doses of a biofertilizer, formulated with a mix of plants (BMV), on the growth, production and nutrients in coriander cultivar Verdão. The BMV was prepared with crushed parts of the species Flemingia macrophylla, Musa sp. and Azolla sp. The trial was carried out in a greenhouse, in Yellow Argissol, with medium texture (V= 36.4%). The experimental design was of randomized blocks with six replicates. Besides BMV doses (0, 5, 10, 15 and 30%, in water), an additional treatment with bovine manure biofertilizer was added (10% in water). Inorganic ingredients blended into biofertilizers as chicken manure were incorporated in soil of growing-beds. The evaluated traits responded to BMV doses linearly. A decrease in green mass (GM) of plants, from 1.43 to 0.88 kg/m 2 , which is the commercial product, and plant height, from 31.33 to 24.02 cm, was attributed to the astringency of Musa sp. in the biofertilizer, together with N shortage. The plant aerial part dry mass (DM) increased from 11.29 to 13.75 g/100 g due to fibrous stems under nitrogen deficiency. Nutrient contents increased (B and Zn), did not range (N, S, and Cu) or decreased (P, K, Ca, Mg, Fe and Mn) and accumulation increased (N, S, K, B, Zn and Cu), decreased (Fe) or did not change (P, Ca, Mg and Mn). The analysis of the principal components showed DM and accumulations of P, K, Ca, Mg and S in the same direction and antagonism of N with Ca and Mg, attributed to loss of N at alkaline pH, by natural phosphate (FN) in BMV. And also, DM, B, Cu and Zn accumulations increased concomitantly while accumulations of Fe and Mn did not compete. The manure biofertilizer surpassed the BMV in GM (1.38 and 1.21 kg/m 2 , respectively), as well as accumulations of N and K.Keywords: Coriandrum sativum, organic manure, alternative fertilizer. RESUMO Crescimento, produção e nutrientes no coentro cultivado com biofertilizanteObjetivou-se avaliar o efeito de doses de um biofertilizante de materiais vegetais (BMV) sobre o crescimento, produção e nutrientes no coentro ′Verdãoʼ. O BMV foi preparado com partes trituradas das espécies Flemingia macrophylla, Musa sp. e Azolla sp. O ensaio foi conduzido em cultivo protegido, em Argissolo Amarelo textura média (V%= 36,4). O delineamento experimental foi de blocos ao acaso com seis repetições. Além das doses do BMV (0, 5, 10, 15 e 30% em água), foi adicionado um tratamento com biofertilizante de esterco bovino (10% em água). Os biofertilizantes receberam ingredientes inorgânicos e foi incorporado esterco de galinha ao solo. As características avaliadas responderam às doses do BMV linearmente. Houve decréscimo da massa verde (GM) de plantas, de 1,43 a 0,88 kg/m 2 , que é o produto comercial, e da altura de planta em 31,33 a 24,02 cm, atribuídos à adstringência conferida pela Musa sp. ao biofertilizante, junto com escassez de N. A massa seca da parte aérea (DM) incrementou de 11,29 a 13,75 g/100 g devido às hastes mais fibrosas sob carência de N. Os teores dos nutrientes aumentaram (B...

Biotisation of Vegetables

“…Regarding the recovery of soils, the product obtained is easily used in the prevention of soil erosion [1] and can be considered as a new form of chemical energy alternative to conventional ones [5], as both mycorrhiza-and rhizobium-based products increase the amount of N in the soil as well as K and Mg, the results are similar to those obtained by Borges et al [13], Figueiredo et al [14], Cardoso et al [15], and de Sousa et al [18] for their effectiveness in biotisation.…”

“…Similarly, with the addition of BMV-biofertiliser, the increase in N fell and the contents of Cu and Fe decreased linearly with the increase in biofertiliser. The loss of volatile N is indicated by the alkalinity and aggregation of Ca and Mg in the oil [15].…”
