BOSCHINI-FIGUEROA, Carlos; VARGAS-RODRIGUEZ, Fabián  and  PINEDA-CORDERO, Luis. Evaluation of equipment for broadcast seed sowing of canary and linseed. Agron. Mesoam [online]. 2015, vol.26, n.1, pp.172-180. ISSN 2215-3608.

The objective of this study was to evaluate the effectiveness of two broadcast sowing of seeds equipments. The research was conducted on Ochomogo of Cartago in 2010. Seeds of canary (Phalaris canariensis) and linseed (Linum usitatissimum L) were used. The statistical model used was a model three-way classification. Measured variables were time spent to travel the stretch of work, quantity of seed sown broadcast per second, number of seeds dispersed and peso/m2. The seed distribution was 5.14 mg/sec in both species. Significant differences (p <0.05) between equipments and within them, show very difference download (p <0.01) between the different levels of acceleration and between the opening volley. Was significant (p<0.01) the effect of the addition of aggregates in the seed mix in the order of 21, 14 and 9 kg/ha of pure seed, mixed with 25% and 50% of aggregates, respectively. An analysis of response surface to determine the degree of acceleration required by the pump motor or the level of openness of the broadcast seed handy, along with the level of aggregates in the mix needed to achieve densities of 6, 8 and 10 kg/ha, in each broadcast equipments employee.
