| 1 | Effect of the Growth Promoter VIUSID Agro on the Morphophysiological and Productive Performance of Tobacco Growth(Nicotiana tabacum L.)显示文摘With the objective of evaluating the effect of VIUSID agro on the morphophysiological and productive performance of tobacco seedlings,a randomised block experiment was designed with five treatments and three replications.The variants were:dosage of 0.2,0.5,0.7 and 1.0 L/ha and one control.The variables are recorded at three points of the cultivation cycle 10th,20th and 30th days after planting(DAP).Among the indicators evaluated were the fresh and dry mass of the plants,the leaves per plant,foliar area,the length and diameter of the stalk as well as the characteristics of the root.The rates of physiological growth and agricultural yield were also evaluated.The results showed a significant increase(p≤0.05)in the fresh and dry mass of the plants when VIUSID was used.Regarding the length of the stalk,the average increases of those treated in comparison to the control in the final evaluation were 28.42%,30.51%,41.17%and 38.43%.In terms of the diameter of the stalk and the foliar area in all evaluations,the treatments with VIUSID significantly exceeded the control.The absolute growth rate and net assimilation was significantly higher when the product was used.In the relative growth rate,the most favourable behaviour was the dosage of 0.5 L/ha,in final evaluation.With regard to yield,the best performance with significant differences(p≤0.05)to the other treatments was the dosage of 0.5,0.7 and 1.0 L/ha.Therefore,VIUSID agro had a positive influence on the morphophysiological and productive indicators of the tobacco seedlings. | Kolima Pena Juan Carlos Rodríguez Dilier Olivera Alexander Calero Richel Dorta Jorge Meléndrez Yariel Fernando Veloso Bulent Kukurtcu | 2018 | Journal of Agricultural Science and Technology(B)2018，8，3： | 0 |
| 2 | Productive Response of Brassica rapa L.subsp.chinensis to Application of VIUSID Agro显示文摘In order to evaluate the effect of VIUSID agro on the yield response of a pak choi harvest,a randomised block experiment was designed with four treatments and three replications.The treatments were dosages of 0.1,0.2 and 0.3 L/ha and one control.The number of leaves per plant and the fresh and dry mass of the plant were measured.In addition,growth indexes were evaluated,such as relative growth rate,active growth rate,harvest index and agricultural yield.The number of leaves per plant was significantly greater at 35 days after sowing(das)for 0.2 L/ha and 0.3 L/ha treatments,with increases of 15.0%and 14.17%relative to the control.Regarding plant length and fresh mass at the final evaluation,the treatments using higher dosages produced the best results.Regarding the active growth rate,the 0.2 L/ha dosage produced the best effects,and regarding relative growth rate,the 0.2 L/ha and 0.3 L/ha dosages produced the best results relative to the control.The harvest index did not benefit from the used dosages,while a higher agricultural yield was achieved using the 0.2 L/ha and 0.3 L/ha dosages at 18.03%and 12.88%compared to the control.Therefore,VIUSID agro positively influenced the yield behaviour of pak choi. | Kolima Pena Calzada Dilier Olivera Viciedo Alexander Calero Juan Carlos Rodríguez Bulent Kukurtcu Yanet Milagros Placenciaálvarez Alexei Castro Salas | 2019 | Journal of Agricultural Science and Technology(B)2019，9，2： | 0 |
