In the houses of protected crops Agricultural Company República Dominicana, Carlos Manuel de Céspedes municipality, Camagüey, an experiment was developed to evaluate different doses of bionematicide HeberNem in controlling the nematode Meloidogyne incognita Chitwood and his participation in the growth and development of the tomato (Solanum lycopersicum) crop, the experimental design was in randomized blocks, the test was composed of 8 treatments replicated twice, evaluating a total of 40 plants for each treatment which were measured: plant height, stem diameter the number of leaflets, the number of clusters per plant, number of flowers per cluster and number of fruits per bunch, they were made weekly. Also at the end of the campaign took root degree determined according to the scale indicated by Zeck, (1971). Data were analyzed using analysis of variance and determined the levels of statistical significance at 5%, by dócima Tukey multiple range. We found an inverse relationship between the parameters of growth and development weighed against the presence of M. incognita Chitwood. At doses of 8 l / ha, 12 l / ha and 16 l / ha were achieved better results in controlling the nematode M. incognita Chitwood. [ABSTRACT FROM AUTHOR]

This research was done in net houses at Empresa de Servicios (ESUNI) del Grupo Empresarial Cuba Níquel, in Moa municipality, Holguín. The objective was to evaluate the agronomic response of tomato cultivars to the application of chitosan, as an alternative to increase yield. Five doses of chitosan (250, 275, 300, 325, 350 mg/ha and control treatment) were evaluated after transplantation. They were applied during the bloom stage in two moments, and an average of the both moments were obtained and their results were presented in tables and graphs. The main production indicators were evaluated. The two-way analysis of variance (ANOVA) and the Tukey's range test were used with p d" 0.05 and Statistica 8.0 software was used to perform the statistical analysis. According to the response of plants to the application of the polymer in the different evaluated variables of both experiments, it was confirmed that chitosan have the capacity to stimulate the processes linked to plants growth and development. The 275 mg/ha dose had the highest yield. [ABSTRACT FROM AUTHOR]

The distribution was determined by stratum and fenology in the plant of tomato of Keiferia lycopersicella at greenhouses. It was developed in the Interprise of Several Crops "La Cuba", in Ciego de Ávila province. 4 greenhouses were used chosen at random planted with hybrid of tomato HA-3105 and HA-3108. The samplings was realized beginning of December 5, 2006 to April 10, 2007, once per week, in 100 leaves distributed in 33 you plant at random in diagonal. They were written down the total of leaves with eggs, larva and it determined the percentage of affected plants and the total of empty mines and you activate. K. lycopersicella had a distribution in both hybrid and in all the strata of the plants. The strata means and inferior were preferred as places of feeding of the larvae that the superior stratum. In all the cases the percentage of affected plants went superior to 55 %, and in three greenhouses obtained 100 %. K. lycopersicella had a populational increment to the 60 days with values between 82,40 % and 84,74 %. [ABSTRACT FROM AUTHOR]

Research was developed to determine the influence of different doses of Pinus caribaea Morelet var. caribaea in the germination of the arvenses that you/they grow associated to the Green House and determine the influence of different dose of P. caribaea on some of the vegetable crops species that grow in this green house located in the solid one mountainous of the Escambray. In both experiments a design multifactorial was used where the independent variables were Types of Dose, Moment of Evaluation of the Germination and as dependent variable the Germination was used. In the first experiment it was found that the highest doses, 80 and 100 %, respectively, they had inhibitory effects on the germination of the arvenses associated to the Green Houses.

With the aim to evaluate the use of four antagonistic bacteria against Stemphylium solani was carry out an study under greenhouse conditions. In this experiment was used America 3 tomato hybrid. The design of the experiment consisted on the use of an array of 60 plants for treatments. For it were used the bacteria Pseudomonas aeruginosa, strain 7NSK 2, Pseudomonas fluorescens, strain CMR 12, Serratia plymuthica, strain 1270 and Bacillus subtilis strain ATCC 6051. The inoculums bacterial was made on King B medium and the suspensions concentration of them were adjusted 108 UFC/ml. The applications were carried out every seven days with a manual atomizer in hours of the afternoon. The evaluations consisted on evaluating in a total of 45 plants for treatments the incidence of the disease in three moments and with a weekly frequency. The results showed statistical differences among the antagonistic bacteria in the control of Stemphylium solani, being achieved the smallest percentages of incidence (< 25 %) in all the cases with the bacteria B. subtilis until the phonological phase of the third floral formation cluster. The use of this antagonistic bacterium in the tomato greenhouses constitutes an alternative healthy environmentally. [ABSTRACT FROM AUTHOR]

A study was carried out to determine the effect of low doses of X-rays on some physiological indicators of tomato seedlings FA-180, in greenhouse cultivation during the months of July-August 2010. The treatment was carried out in a source of low-power irradiation (11.47 Gy / min) in the morning hours at doses of 5, 10 and 20 Gy with a Phillips x-ray machine; model RT-100, with a duty cycle of 30 kV and 10 mA. The evaluated indicators were seedling height, root length, stem diameter, fresh stem weight, dry stem mass, fresh root weight and dry root mass. Results indicated a significant stimulation (p d" 0.05), for indicators as seedling height, root length, stem diameter, fresh stem mass, dry stem mass and fresh root mass related to the control, which corroborates the stimulating effect of this treatment on seedling growth.

The research was conducted in a unit of protected crops ¨La Quinta¨ belonging to the Empresa de Cultivos Varios Sancti Spíritus, from March to July 2011, in a greenhouse of 540 m2. The tomatoes (Solanum lycopersicum L.) variety used was HA 3163 of indeterminable grow. The objective was to determine the stimulant effects of two liquids formulation of Trichoderma harzianum A-34 fermented up to the micelial phase without conidia and with conidia at two dosages (50 y 100 ml/l) in comparison with a control without treatment, with a completely randomized design. Weekly evaluations were conducted to count the number of leaf and flowers per plant upt to day 57 from the date up planting and 35 days after planting it was done an evaluation of the high of the plant, long and wide and number of folios of the leave number 6. Foliar treatment with Trichoderma harzianum A-34 increased the number of leafs, flowers, the height of the plant, the length and the width of the leafs, the quantity of follies and the yield.
