Producción de semilla certificada de maíz (zea mays l.) Iniap h–551 en tres distribuciones de parentales

This research was conducted at the National Institute of Agricultural Research (INIAP) Tropical Station Pichilingue, located at kilometer 5 of the Quevedo route - El Empalme, Canton Quevedo, Los Rios Province Republic of Ecuador and lasted 5 months (April-August 2016). the method suitable planting for the production of certified corn hybrid triple INIAP H-551 seeds was determined, planting of the three treatments with six replicates, which consisted of distributions 1: 3 which consisted of planting 4 males seeds and six females seeds (T1), 1: 4 who settled in the planting of 4 male seeds eight seeds females (T2), 1: 5, which was based on the planting of 4 male seeds and 10 seeds females (T3). one DBCA was applied. The variables recorded were: rows of kernels per cob (HGM), which existed no significant differences according to Tukey test (p ≤ 0.05) between treatments, length of ears (LM), which showed that there was no statistical significance applying the Tukey test (p ≤ 0.05) per distributions, ear diameter without bracts (DMB), where it was shown that the highest average distribution was found in 1: 4 (T2) with 4,21 cm being statistically different from the distribution 1: 5 (T3) with 4.05 cm which recorded the lowest value according to Tukey test (p ≤ 0.05), ear weight (MW) distribution was observed that 1: 4 (T2) had the highest average with 126.95 g being statistically different from the distribution 1: 3 (T3) with 116.38 g according to Tukey test (p ≤ 0.05), weights 100 seeds (PCS) which is not evidenced significant between treatments according to the test Tukey (p ≤ 0.05) cost of treatment (CT) noting that production costs amount to 954.10 ; 1,199.16 and $ 1,442.97 for treatments T1 , T2 and T3 respectively, while revenues correspond to 9557.14 ; 11,628.14 and $ 12,733.70 respectively. These data enabled profitability for each of the treatments under study determined that the best treatment was the T1 with 902 % return, followed by T2 with 870 % and finally the T3 with 782 % return . In any case, all treatments were profitable , however , because the T1 reported lower costs get the best return.
