Evaluating the Productivity of Radish Fertilized with a Mixture of Hairy Woodrose (Merremia aegyptia L.) and Carnauba Straw (Copernicia prunifera)”

Abstract

Aims: The use of spontaneous species present in agricultural areas is of utmost importance for farmers who cultivate in the agroecological system. Place of Study: The experiment was conducted from June to August 2023 at the Rafael Fernandes experimental farm, in the district of Alagoinha (5º03'37 "S, 37º23'50" W), northwest of Mossoró, State of Rio Grande do Norte, Brazil, with the aim of evaluating the In study the productivity of radish fertilized with a mixture of hairy woodrose (Merremia aegyptia L.) and carnauba straw (Copernicia prunifera). Study Design and Methodology: The treatments consisted of five amounts of a mixture of hairy woodrose with carnauba straw (0.0; 1.2; 2.4; 3.6 and 4.8 kg m-2 of area). The spacing used was 0.2 x 0.1 m, with a pit-1 plant. The total area of the plot was 1.1 x 0.6 m, corresponding to 0.66 m-2, with a useful area of 0.42 m-2, consisting of twenty plants. Agronomic characteristics of Radish (Raphanus sativus L.): Plant height; root diameter; productivity of the area plus root; root weight and total dry mass and root dry mass. Conclusion: The amount of 4.5 kg m-2 of the mixture of hairy woodrose plus carnauba straw was what promoted the greatest increase with a maximum value of 1626.66 g m-2 for the aerial part plus root characteristic. The use of a mixture of fertilizers of plant origin is promising for the development of radish in the Mossoró-RN region, Brazil.
