Clinical Trial about Vegetative Growth

In order to evaluate the effects of Enraivell on the root system and its indirect effect on vegetal development and growth in tomato plants, a greenhouse test was carried out in a sanded soil crop under an intensive ecological agricultural model in the municipality of Níjar.

In this experiment were used Laujar-variety Solanum Lycopersicum L. tomato plants. Seedlings from El Plantel seedbed were transplanted to the greenhouse with two true leaves. This study was carried out during the 2017-2018 season, the growing started on July 24, 2017.Ten plants were randomly analyzed based on the treatment and number of repetitions to evaluate their aerial and root systems.

In order to evaluate the effects of Enraivell on the root system and its indirect effect on vegetal development and growth in tomato plants, a greenhouse test was carried out in a sanded soil crop under an intensive ecological agricultural model in the municipality of Níjar.

In this experiment were used Laujar-variety Solanum Lycopersicum L. tomato plants. Seedlings from El Plantel seedbed were transplanted to the greenhouse with two true leaves. This study was carried out during the 2017-2018 season, the growing started on July 24, 2017.Ten plants were randomly analyzed based on the treatment and number of repetitions to evaluate their aerial and root systems.

2. OBJECTIVE OF THE TEST

The test is intended to demonstrate the effectiveness of the use of Enraivell on root development and density in tomato plants (Laujar variety) transplanted into a greenhouse in sandy soil crops.

3. FERTILIZING PRODUCT DESCRIPTION - TEST SUBJECT

Enraivell is a rooting agent and bionutrient which is easily and rapidly assimilable by the plant, it contains essential macro and micronutrients along with algae extract (Ascophyllum Nodosum) in addition to physiologically active and functional L-α-amino acids. Enraivell is especially suitable for support rooting, activate the root system and to stimulate the growth of all kinds of crops during the first phases of the plant cycle.

4. MATERIALS AND METHODS

The test aims to demonstrate that the fertilizer product Enraivell is ideal for the beginning of the crop, during the transplant phase to improve plant rooting capacity after the stress resulting from the transplant by providing more vitality to the plant and improving plant's aerial system.

4.1 Location and Test Farm

The test farm belongs to a farmer named Sergio, and is located in the rural side of Níjar, specifically near San Isidro. The test surface is 6,000 m2. The greenhouse was divided into two sectors so that both areas (control and treated area) had the same ​​cultivation surface, each of them is 3,000 m2.

4.2 Vegetal Material

The vegetal material studied in this test was Solanum Lycopersicum (Laujar variety) from Seminis seed company, the seeds were grown in El Plantel seedbed from the moment they were planted until the appearance of 3 true leaves. The transplant date was on 07/24/2017. The planting density was 2 plants per m2.

Plant characteristics: The plant is a variety of red caliber M loose tomato suitable for picking from the bouquet. Open short internodes plant with very uniform and long bouquets with thick rachis. Its caliber is mostly M (about 70%) and G (about 30%), fruits have no tendency to crack in hot conditions.

4.3 Experimental Design

During the initial phase, several treatments were performed using Enraivell in a systematic way comprising the following experimental treatments:

T0: Control treatment.
T1: Application of Enraivell at a rate of 2 L·ha-1

Four repetitions will be performed for each treatment, making up a total of 8 virtual experimental units (VEU). The virtual experimental units were identified using picket signs (T0: Control, T1: Enraivell 2L·ha-1).

Figure 1 shows the design in the greenhouse. 

The Enraivell applications were applied on the root, evenly distributing the mixture through the irrigation system.

Cultivation: Loose Tomato FIELD TESTS AND STUDIES No Test Farmer: Sergio EC-01.17-18

Treatments

Sampling

Data collection in the greenhouse was done by selecting 10 plants randomly from each of the treatments (Control area and area treated with Enraivell). Photographs of each of the samples (M1, M2, M3 and M4) were taken, the height of the plant (from stem to apical meristem) and the number of true leaves were quantified.

5. RESULTS AND DISCUSSION

Samplings during the test (M1, M2 and M3)

The data evaluated during the first 35 days after the transplant correspond to the aerial part of the plant where the height of the plant and the number of leaves per plant were quantified.

Figure 2 shows the growth dynamics of the plant during its cultivation. The variance analysis showed significant differences between the treatments (Table 3). From the first sampling corresponding to 11 days after transplant, significant differences between the plants were observable, the plants that were treated with Enraivell had a higher height, this behavior in the growth did not vary during the period of time the test lasted.

Figure 2: Plant height according to treatments applied during the initial phase of the crop corresponding to the first month after transplantation: 11, 21, 31, 35 days after transplantation (DAT). T0: Control; T1: Treated with Enraivell.

As for the number of leaves developed in both the control plants and the treated plants, there were no significant differences during the first two samplings.

Sampling 4

In the last sampling, both aerial and root data were evaluated.

The biostimulant Enraivell, based on the results obtained (Table 3), manages to significantly increase the root development in tomato plants 30 days after transplantation. The aerial weight is also increased thanks to the growth of the root system affecting in a positive way both leaf area and the thickness or lignification of the stem of the plant, this was achieved thanks to the repetition of the treatments with Enraivell obtaining a cumulative effect of stimulation of the root and the aerial systems.

In addition, plants which received repeated applications of Enraivell had higher root density than the control plants (Figure 2). It was also observed that the plants treated with Enraivell had a greater number of flower bouquets than the control plants, confirming that Enraivell improves the phenological state of the plant as result of an improved root system.

Aerial biomass was also influenced by the treatment with Enraivell because an increase in the aerial dry weight of the treated plants was observed when compared to the control plant, stimulating the growth and development of the tomato crop (Table 4). Additionally, we can affirm that plants treated with Enraivell have significant differences in aerial and root weight when compared to control plants.

It should be noted that throughout the study no symptoms of phytotoxicity were observed in plants treated with Enraivell.

6. CONCLUSIONS

The conclusions described below are based on the application of Enraivell at a rate of 2L/ha on the roots of the plants.

  The application of Enraivell increases the development of roots due to an increase of the root biomass (increase of the dry and moist weight of the roots).

 The application of Enraivell improves the phenological state of the plant.

 Repeated application of Enraivell® increased foliar mass 35 days after the transplant.

  Enraivell application increased leaf mass, stem lignification and height of the plant 35 days after transplantation.

 Applying the studied dose of Enraivell does not cause phytotoxicity in the plants.
