Efecto de densidades de siembra sobre el Comportamiento productivo de tres Variedades de maní (Arachis hypogaea L.) en Manglaralto Santa Elena.

The experiment was carried out at the UPSE-Manglaralto practice center, in order to determine the effect of seed densities on the production of three varieties of peanuts. In the statistical part, the experimental design divided plots was used; the factors analyzed were: large plots (varieties: INIAP-380, 381 and 383) and sub- plots (densities: 0.40 m between rows and 0.20; 0.30 and 0.40 m between plants), generating 9 interactions. Statistical results indicate that the interaction density 1 (0.40 x 0.20 m) and variety 1 (INIAP 380) showed a different behavior than the other interactions and revealed that INIAP-380 is more susceptible to increased densities, as the increase of the plants decreases the production of pods from the density 2. Regarding the variables shell almond and weight of 100 seeds, there are significant differences only in the factor varieties, standing out INIAP-381 in the first variable with a value of 23.14% and in the second the best was INIAP-383 with a value of 70.63 g. Regarding the components of yield, pods per plant and production (kg / ha), significant differences are established in the factors varieties and densities; being INIAP-381 and 383 the best to obtain 24.7 pods per plant with density (0.40 x 0.40 m), and yields of 5191.56 and 4899.78 kg / ha respectively, when density (0.40 x 0.20 m) was used. The economic analysis determined that INIAP-381 and 383 in interaction with density (0.40 x 0.30) achieved a better cost-benefit ratio with 1.83 and 1.72. Based on these results, it can be concluded that; the varieties with the best agronomic and productive performance were INIAP-381 and 383.
