Production of coriander fertilized with a mixture of hairy woodrose (Merremia aegyptia L.) with rooster tree (Calotropis procera) plus goat manure in a latosol

The practice of fertilization with spontaneous species from the semiarid region is of great importance for farmers who work in the organic production of vegetables, bringing promising results. In this sense, the objective was to study the production of coriander fertilized with the mixture of hairy woodrose (Merremia aegyptia L.) with rooster tree (Calotropis procera) plus goat manure in a latosol. The research was conducted at the Rafael Fernandes Experimental Farm, belonging to the Federal Rural University of Semi-Árido (UFERSA), from July to September 2024. The experimental design used was a randomized complete block design, with six treatments and four replicates. The treatments consisted of six amounts of the mixture of hairy woodrose (Merremia aegyptia L.) with rooter tree (Calotropis procera) plus goat manure (0.0; 1.2; 2.4; 3.6; 4.8; 6.0 and 7.2 kg m-2 on a dry basis). The coriander cultivar used was “Verdão”. The spacing used was 0.1 x 0.05 m with five plants per hole, corresponding to 1000 plants m2 of area. The characteristics evaluated were: plant height (cm plant-1); number of stems (plant-1 units); production (g m-2 of area), number of bunches (m-2 units of area) and dry mass (g m-2 of area). The maximum production of coriander and number of bunches was observed in the mixture of spontaneous species with goat manure at doses of 6.72 and 5.6 kg m-2, with values of 767.20 g m-2 and 7.77 units of bunches m-2. The mixture of alternative fertilizer sources in vegetable cultivation is extremely important.
