Avaliação do método de multiplicação rápida da semente - estaca de Mandioca para as condições da região sul de Moçambique

Abstract

An experiment was conducted at the Umbelúzi Agricultural Station, South Zonal Center, Mozambique Agricultural Research Institute. Located in the district of Boane, in the Maputo province, with the objective of evaluating the method of rapid multiplication of seed-stock of cassava for the conditions of the southern region of Mozambique. A completely randomized design (CCD) was used. where the planting positions and depths were fixed, having four (4) treatments and three (3) treatments and three (3) repetitions, totaling twelve (12) experimental units. experimental unit was composed of 16 mini-picks, with four (4) rows and four (4) (4) mini-picks per row, in all bed had 192 mini-picks of cassava. For the conduction of the trial was carried out the planting of mini-stakes on October 24, 2014 in the plots, at a spacing of 10 cm between rows and 10 cm between the mini-picks in the same line. The variables studied in this work were: sprouting index in the different positions and planting depths of the mini cuttings. We tested the homogeneity of observations was tested using the Crochran test at 5% probability, where the variances were found to be homogeneous, and proceeded by the analysis of variance variance to the satisfaction of the F test. In comparing the means of the treatments, Tukey's test was used at 5% probability. The position and depth influenced significantly on the number of shoots on the mini-tests. In the vertical planting position the depth of 1/3 cm showed higher sprouting emission at 21 days after planting. after planting. The horizontal position is the best for the planting of mini-cuttings. A planting depth of 3 cm is the best for obtaining the highest rate of sprouting of the of the mini-tests at 21 days after planting. (TRADUÇÃO NOSSA)
