The Use of Scarlet Starglory (Merremia aegyptia L.) Mixed with Poultry Manure in the Agronomic Viability of Coriander in the Semiarid Region

Aims: This research was aimed to study udy the use of jitirana mixed with poultry manure on the agronomic viability of coriander in the semiarid region.

Study: The experiment site was in the municipality of Mossoró, RN, Brazil, located at 5º 11' south latitude and 37º20' west longitude and altitude of 18 m.

Methodology: The experiment was carried out at the Rafael Fernandes Experimental Farm, belonging to the Universidade Federal Rural do Semi-árido, located in the district of Alagoinha, rural area of Mossoró, Brazil. The experimental design was completely randomized with treatments arranged in a 5 x 2 factorial scheme, with three replications. The treatments consisted of the combination of five amounts of the mixture of scarlet starglory (Merremia aegyptia L.) plus poultry manure (0.0; 1.2; 2.4; 3.6 and 4.8 kg m-2 of area in dry basis) and the second factor, by the forms of application to the soil (incorporated and covering).

The sown coriander cultivar was the Verdão cultivar. The characteristics evaluated were the following: plant height, number of stems plant-1, productivity, number of bunches and dry mass of coriander.

The highest productivity and number of bunches of coriander culture was observed in the amount of 4.8 kg m-2 of the mixture of scarlet starglory with poultry manure, with values of 1246.5 g m-2 and 24.9 units of bunches m-2, respectively. The mixture It is concluded that the misture of organic fertilizers (scarlet starglory with poultry manure) contributed positively to the agronomic characteristics of the coriander crop.
