Influence of Soil Types and Quantities of the Mixture of Hairy Woodrose (Merremia aegyptia L.) Plus Bovine Manure on the Agronomic Viability of Coriander in the Semiarid Region of Brazil

Abstract

Aims: Coriander cultivation is an activity of great importance for family farmers in the Brazilian semi-arid region. In this sense, the objective was to study the influence of soil types and quantities of a mixture of hairy woodrose (Merremia aegyptia L.) and cattle manure on the agronomic viability of coriander in semi-arid region of Brazil. Place of Study: The experiment was carried out in the greenhouse of the Agricultural and Forestry Sciences department of the Universidade Federal Rural do Semi-Árido, Brazil. Study  Design and Methodology: The design used was completely randomized in a 4 x 2 factorial scheme, with three replications, being the first factor consisting of four quantities of the mixture of hairy woodrose (Merremia aegyptia L.) plus cattle manure (0.0; 1.5; 3.0; 4.5 and 6.0 kg m-2 of area) and the second factor consisted of two types of soil (latosol and an argisol) in single cultivation.The coriander cultivar "Frevo" was used, adapted to the edaphic and climatic conditions of the semi-arid region. The spacing used was 0.1 x 0.05 m with five plants pit-1, corresponding to 1000 plants m-2 of area. After harvesting the coriander, the following characteristics were evaluated: plant height (expressed in cm plant-1); number of stems (expressed in plant-1 units); productivity (expressed in grams m-2 of area); number of bunches (expressed in plant-1 units) and dry mass (expressed in grams m-2 of area). Agronomic Characteristics of Coriander: Plant height (expressed in cm plant-1); number of stems (expressed in units plant-1); productivity (expressed in grams m-2 of area); number of bunches (expressed in units plant-1) and dry mass (expressed in grams m-2 of area). Conclusions: There was no interaction between the factors studied, with the amount of 3.0 kg m-2 of the hairy woodrose (Merremia aegyptia L.) mixture with cattle manure, promoting the greatest increase in coriander cultivation, with values of 1030.6 g m-2, equivalent to 20.87 units of coriander bunches m-2, respectively. In relation to soil types (latosol and an argisol) there was no statistical difference, with values of 841.9 and 709.6 g m-2 for productivity, equivalent to 16.7 and 14.0 units of coriander bunches m-2.
