Intervalos de corte de pasto Janeiro (Eriochloa polystachya Kunth) M2 irradiado con rayos gamma

Abstract

The janeiro grass (Eriochloa polystachya Kunth) is a species used in forage with characteristics welcome to thrive in marginal conditions that need to be improved in its nutritional value or other agronomic characteristics. Gamma rays can be used for the genetic improvement of plants and generate mutations that can be useful. The research was carried out with the objective of determining the best cutting time. The study was carried out in the field of the Faculty of Agricultural Sciences of the Technical University of Babahoyo. Five doses 0; 25; fifty; 75 and 100 gamma ray gray Co60. Two cutting times 25 and 40 days after the equalization cut and two doses of fertilization with N-P-K were evaluated. A randomized complete block design (DBCA) with factorial arrangement was used, which were contrasted with the Tukey test at 95% probability, with the statistical package InfoStat. The averages were for branch length 1.94 meters, leaf length and leaf width 30.76 cm and 1.82 cm respectively, the best protein percentage was present in the control with 12.29%.
