    Evaluación del biosol generado en la producción de biogás, como biofertilizante en el cultivo de lechuga (Lactuca sativa)
    (2019-03) Martínez Barreno, Byron Alberto; Muñoz, Manolo
    The research work entitled "Evaluation of the biosol generated in the production of biogas, as biofertilizer in the lettuce crop (Lactuca sativa)" was carried out in order to identify the effects of biosol on the production parameters of the lettuce crop. The research was carried out in the Querochaca experimental teaching farm, located in the canton of Cevallos, province of Tungurahua. Its geographic coordinates are 01 ° 22' 02 "South latitude and 78 ° 36' 20" West longitude, at an altitude of 2 865 meters above sea level. The randomized block design was applied, 5 treatments with 4 repetitions, in addition Tukey significance tests were performed at 5% for the treatments that were significant, the following results were obtained: variable plant height at 0 days treatment 5, conventional fertilization (FC) was the best with an average of 7.03 cm and treatment 3 with the application of biosol 1 kg.m-2 (B1.0) was the lowest with 3.18 cm, at 60 days for this variable treatment 4 with the application of 2 kg.m-2 of biosol (B2.0) was greater with an average of 15.25 cm and treatment 1 with 0 kg.m-2 of biosol (B0, 0) was the smallest with 12.84 cm. The variable weight of foliage presented significance, (FC) at the beginning of the trial was the best with an average of 12.08 g and the lowest weight was the treatment (B1.0) with 8.03 g, at 60 days it presented significance in where (B2.0) with an average of 157.75 g was the best and the one with the lowest average was (B0.0) with 99.21 g, at the time of harvest this variable presented significance, being the treatment (FC) the best with an average of 708.75 g and the lowest was (B2.0) with 443.06 g. For the variable root volume there is significance where (FC) with an average of 11.15 cm3 was the best while (B1.0) was the lowest with 9.03 cm3, at 60 days (B2.0) with an average of 13.00 cm3 was the best and (B0.0) was the lowest value with 8.60 cm3. The variable equatorial diameter at harvest showed significance, (F.C) with a mean of 9.95 was the best, (B2.0) was the lowest with 7.73 cm. For the polar diameter variable there was no significance, however (F.C) presented an average of 8.99 cm. The yield variable presented significance (F.C) was the best with 94499.34 kg / ha and (B2.0) was the lowest with 59074.00 kg / ha.
