USO DE JITIRANA INCORPORADA À ADUBAÇÃO COM ESTERCO BOVINO NA CULTURA DA RÚCULA CV. FOLHA LARGA

Abstract

An experiment was carried out at a greenhouse of Plant Science Department of the Universidad Federal Rural do Semi-Arid (UFERSA), Mossoró-RN, in the period of May to June of 2006, with the objective of determing the best treatment with scarlet starglory (Ipomoea glabra) incorporated to with cattle manure on rocket performance cv. Folha Larga. A completely randomized desing with seven treatments and three replications. The treatment consist of: T1 - 113g pot-1 of scarlet starglory in green base plus 21g pot-1 of cattle manure; T2 - 76g pot-1 of scarlet starglory in green base plus 42g pot-1 of cattle manure; T3 - 38g pot-1 of scarlet starglory in green base plus 63g pot-1 of cattle manure; T4 - 151g pot-1 of scarlet starglory in green base; T5 - 84g pot-1 of cattle manure; T6 ¿ Fertilization with NPK at the recommended dose for the crop and T7 - Control (no Fertilized soil). The rocket cultivar grown was Folha Larga. The evaluated traits were: plant height, number of leaves per pot, shoo fresh and dry mass. All the evaluated traits were significantly affected by the amounts of scarlet starglory incorporated. Height mean value for plant height, shoo fresh, dry mass and number of leaves were obtained in the amount of scarlet starglory incorporated of 151 g pot-1.
