Abstract
Aims: Vegetable farming is widely practiced by farmers in the semi-arid region who use spontaneous species as organic fertilizer, in this sense, the objective was to study the spontaneous species woods pasture (Senna uniflora L.) in addition to rooster tree (Calotropis procera) in different quantities in the production of coriander in the semi-arid region of Brazil.
Place of Study: The experiment was conducted in a greenhouse at the Department of Agricultural and Forestry Sciences, in the region of Mossoró, RN, Brazil, using soil classified as argisol.
Study Design and Methodology: The design used was completely randomized, with five treatments and four replications, with the treatments consisting of the following amounts of the mixture of woods pasture (Senna uniflora L.) plus rooster tree (Calotropis procera) (0.0; 1 .2; 2.4; 3.6 and 4.8 kg m-2 of area). The coriander cultivar "Frevo" was used, adapted to the edaphic and climatic conditions of the semi-arid region.
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).
Conclusion: The mixture of woods pasture plus rooster tree in the amounts of 4.8 kg m-2, obtained the highest productivity and number of bunches, with values of 868 g m-2 and 17.3 units of coriander bunches, respectively. Spontaneous species from the semi-arid region constitute an organic fertilizer alternative for farmers.
