Efecto del uso de nanofertilizantes e hidroretenedores en el cultivo de zanahoria (Daucus carota L.)

Abstract

The present work was carried out in the Ambato canton, Augusto Martínez parish, Caserío Samanga in order to observe the effect of the use of nanofertilizers and hydro-retainers in the carrot (Daucus carota L.) crop as an alternative to the lack of irrigation water. The environmental conditions of the place are: temperature 17.0 ° C and precipitation 500.00 mm. Two factors were studied: Factor A, evaluated the effect of three levels of Nanofertilizers: 2.5 ml / liter, 5.0 ml / liter and 7.5 ml / liter plus a control without application of Nanofertilizers and factor B, evaluated the effect of two levels of Hydroretainers: 5.0 g / 2 m2 and 10 g / 2m2, under a combinatorial arrangement and a completely randomized block design with 4 repetitions per treatment and a total of 36 plots. The results of the effect of applying nano-fertilizers determined with highly significant differences: the best germination of the carrot seed when using N2 and N3 with 85.02 and 85.86%, respectively; the highest results in the germinating leaf area N3 cm2; the highest values in root volume in N3 with 234.92 cm3; the highest moisture retention during germination, vegetative development and thickening in N3 with 4.73, 4.29 and 5.00% humidity, respectively, and the highest in coarse and even carrot in N3 with 120,726.23 and 36,603, 33 Kg, respectively and in this same treatment, the lowest rejection productions were determined with 19,427.22 Kg. The results of the application of Hydroretenedores, were achieved with statistical differences in the leaf area during germination, vegetative development and thickening in H2 with 14.90; 53.53 and 71.84 cm2, respectively; The highest values in the root volume in H2 with 231.00 cm3; in retention of humidity during germination, vegetative development and thickening in H2 with 5.30; 4.77 and 5.30%, respectively and in the yields in coarse and couple in H2 with 132,244.33 and 42,792.81 Kg, respectively, and at this same level the lower rejection production was deducted with 19,402.75 Kg. In consideration of the results achieved, it is recommended to use levels of 7.5 ml / liter of nanofertilizers and hydroretainers up to 10 g / 2m2 due to having recorded flattering results in the variables: seed germination, germinating leaf area, vegetative development and thickening; root volume; moisture retention in germination, vegetative development and thickening; yield of the carrot crop in thick and even and detect a lower rejection.
