NODA, Yolai  and  MARTIN, Giraldo. Effect of the sowing density on the establishment of mulberry aiming to its inclusion in livestock production systems. Zootecnia Trop. [online]. 2008, vol.26, n.3, pp.339-341. ISSN 0798-7269.

With the objective of determining the effect of planting density on the initial growth of mulberry, during the establishment stage, three planting densities were studied: 12500, 25000, and 37500 plants/ha. For this a completely randomized design was used. The period of evaluation was 10 months. Five plants were randomly selected in each plot and the height and number of branches were measured monthly. For data analysis a factorial design was used. For the variable height statistical differences were observed (P<0.05) among densities. With the density of 25000 plants/ha the highest height was reached (90.8 cm), as compared to the other two densities (79.0 and 68.4 for 37500 and 12500 plants/ha, respectively). Regarding the number of branches, the highest values were found when using the lowest planting density (12500 plants/ha). It is concluded that the highest plants were obtained with the density of 25000 plants/ha, while that planting at densities of 12500 plants/ha, higher branch numbers were obtained. To continue the study during the exploitation stage of the crop is recommended, with the objective of evaluating the influence of this factor on the yield and bromatological composition of the plants.
