INFLUÊNCIA DA JITIRANA EM COBERTURA COMO ADUBAÇÃO VERDE SOBRE O DESEMPENHO AGRONÔMICO DA ALFACE

Abstract

The experiment was carried out at a greenhouse of Plant Science Department of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró-RN, with the objective of determing the effect green manuring with scarlet starglory in coverage in agronomic performance of lettuce. A completely randomized desing with six treatments and four replications. The treatments consist of: T1 (scarlet starglory in coverage 35 days ; T2 (scarlet starglory in coverage 28 days); T3 (scarlet starglory in coverage 21 days); T4 (scarlet starglory in coverage 14 days); T5 (scarlet starglory in coverage 7 days); T6 - Control (no fertilized soil). The evaluated traits were: plant height, Horizontal and vertical diameter of the root (mm), shoot fresh and dry mass (g); roots fresh and dry mass (g). The time of decomposition of 42 days was the maximum provided for all characteristics evaluated.
