Sources and splitting of the organic fertilization in top dressing in cabbage production Horticultura Brasileira
Cardoso,Antonio Ismael Inácio; Oliveira,Jéssica B; Lanna,Natália BL; Candian,Joara S; Castro,Jean Lucas M.
ABSTRACT Although there exist researches about fertilization in top dressing in the production of cabbage, these are usually made with inorganic fertilizers, being rare the researches with organic fertilization in top dressing in the production of most vegetables. The objective was to evaluate the effect of different splitting of two organic fertilizers in top dressing in the production of cabbage. Six treatments were evaluated, with four replications in randomized block design. The six treatments were the result of the factorial 3x2, with three types of splitting (1/3+1/3+1/3; 4/6+1/6+1/6; 1/6+4/6+1/6 of the total dose in each application) and two organic fertilizers (castor bean cake and organic compost). The total dose of each fertilizer was calculated...

ABSTRACT This study was carried out to evaluate the contributions to the optimization of water use in a carrot crop under different forms of mulch using Gliricidia sepium, fertilization with castor bean cakes and irrigation water depths. The experiment was conducted in Seropédica, RJ, Brazil (22º 46’ S and 43º 41’ W), from June to September 2010. The experiment was conducted using a split-split-plot scheme (5 x 3 x 2), with four replicates. The five plots had irrigation depths corresponding to 0, 43, 72, 100 and 120% of crop evapotranspiration (ETc); the three subplots contained the different forms of mulch (whole leaves (WL) and chopped leaves and branches (CLB)) and the absence of mulch (AM); and the two sub-subplots contained either the presence (PF) or...
