Abstract

The study was carried out in production conditions, in a tobacco area on a Fluvisol soil with tobacco variety Habana 92, under edaphoclimatic conditions at Guisa municipality. Granma Province, Cuba, in the period 2011-2012, with the objective to evaluate the agronomic response of the tobacco crop to the application of chitosan. For this, an experiment was carried out where a dose of 300 mg ha-1 of this biostimulant was applied to 0.5 ha of the planted area and 0.5 ha without application of product. The first measurement was made at the chitosan application time and the second one at harvesting to ten random selected plants which were evaluated for plant height, leaf number and leaf length and wide and agronomic yield. For statistical analysis a simple classification analysis of variance was used and where differences existed the tstudent simple comparison test was applied with p ≤ 0.05 using the statistical package Statistica version 8.0. It was shown the influence that chitosan exerted on the four variables of growth evaluated, due to that in all indicators, the biostimulant application caused higher values in comparison to the control, although there was not any significant differences between application treatment vs. not application for agronomic yield.

 es Efecto de la quitosana sobre el cultivo de tabaco ( Nicotiana tabacum check for this species in other resources Lin.) en condiciones edafoclimáticas del municipio Guisa, Granma, Cuba

Resumen

El trabajo se realizo en condiciones de produccion, en un area tabacalera sobre un suelo Fluvisol con la variedad de tabaco Habana 92, bajo condiciones edafoclimaticas en el Municipio Guisa, Provincia de Granma Cuba, en la campana 2011-2012, con el objetivo de evaluar la respuesta agronomica del cultivo de tabaco a la aplicacion de quitosana. Para ello se realizo un experimento donde se aplico una dosis de 300 mg.ha-1 de este bioestimulante a 0,5 ha del area sembrada y 0,5 ha sin aplicacion del producto. La primera medicion se realizo al momento de la aplicacion y la segunda al momento de la cosecha, a diez plantas, seleccionadas al azar, en las que se evaluaron: altura de la planta, numero de hojas, longitud y ancho de la hoja y rendimiento agricola. Para el analisis estadistico se utilizo un analisis de varianza de clasificacion simple y donde existio diferencias significativas se aplico la prueba de comparacion simple de t-student c on p ≤. 0 ,05 mediante el paquete estadistico Statistica version 8.0. Se demostro la influencia que la quitosana ejercio en las cuatro variables del crecimiento evaluadas, debido a que en todos los indicadores, al aplicar el bioestimulante fueron superiores con respecto al control, aunque no se encontraron diferencias significativas para el rendimiento agricola.

Palabras-clave
Quitosana; bioestimulante; tabaco; rendimiento; altura de plantas; caracteres foliares
