Influencia de bioestimulantes naturales, en el rendimiento del cultivo de cebolla de bulbo (Allium cepa L.) Var Burguesa.

Abstract

The objective of the research was to determine the effect of the application of natural biostimulants on the growth performance of bulb onion (Allium cepa L.) var. Bourgeois. The experiment was carried out at the experimental farm named Querochaca owned by the Technical University of Ambato, Faculty of Agricultural Sciences, located in the Cevallos canton, Tungurahua province. Its geographic coordinates are 01 ° 21 'South latitude and 78 ° 36' West longitude, at an altitude of 2865 meters above sea level. The random block design, factorial of 3 x 2 + 1 with 4 replicates was applied, in addition the Tukey significance tests were performed at 5% for the treatments. The following results were obtained as: for the plant height variable at 30.60 days, there was no significance among the treatments; At 90 and 120 days, significant statistical differences were found, with M5B5 (Maize 5% and Biol 5%) with an average of 46.14 cm and M15B0 (Maize 15% and Biol 0%) with an average of 55 , 93 cm; In the variable number of leaves, polar diameter did not present significant differences, in the equatorial diameter the treatment that best obtained was M15B0 (Maize 15% and Biol 0%) with an average of 7.85 cm; For the weight of the bulbs the best treatment was M15B0 (Maize 15% and Biol 0%) with an average of 236,62 g which is the weight of the bulb onion; For yield the best result was M0B15 (0% Maize and 15% Biol) with an average of 25,57 t / ha-1. It was determined that the biol poultry is the best yield possibly due to pH 7.17 because at basic pH allows the nutrients to be better assimilated by the plants and also the amount of Nitrogen 0.70%, phosphorus 208 ppm and potassium 1.10 % is essential for the growth and vigorous development of the plant, phosphorus stimulates growth and root formation improving the quality of fruits and vegetables, Potassium is important for higher yields and crop quality. For the days at harvest the treatment M15B0 (15% Maize and 0% Biol) is the one that was harvested at 140 days and the other treatments had a delay of 10 to 20 days.
