Daymsa has carried out trials with Pleniflor and Naturfruit with the main objective of analysing the improvement of grain filling and production in soybean.
Soybean is an annual herbaceous plant, spring-summer, whose vegetative cycle ranges from three to seven months and reaches 40 to 100 cm wingspan. It is a plant sensitive to day length
As regards water requirements, during cultivation, soybean needs at least 300 mm of water, which can be in the form of irrigation when irrigated, or in the form of rain in those humid temperate zones where rainfall is sufficient.
Tests carried out
In order to analyse different vegetative and productive parameters and to increase the production of the soybeans crop, Daymsa has carried out trials on a farm in Salamanca on the Havane variety.
Pleniflor® is a flowering activator.
The phenological stages of the application in soybean (between R1 and R3) were as follows, as can be seen in the following table:

Daymsa has carried out a study on seed treatment with Raiza® Mix to analyse the yield and quality of potato production.
Potatoes are one of the most water demanding crops. It needs to have constant availability of this resource to ensure the yield and quality of the tubers, but at the same time it requires well-drained soils to avoid prolonged waterlogging.
During the growing cycle, the potato plants are exposed to the action of a series of pests and diseases, of various origins, which appear during a long period of time, from planting to the end of the vegetative phase. Among the main pests and diseases affecting this crop are the Guatemalan potato moth (Tecia solanivora), the potato flea (Epitrix similars) or the zebra chip (Candidatus Liberibacter solanacearum), the latter usually appearing through invasive insects.
The occurrence of these pests is mainly due to the relatively long period of tuber development in the soil. On the other hand, unfavourable climatic conditions in the period of emergence and subsequent growth of potato plants may be another factor in the occurrence of these pests.
Trials carried out with Raiza® Mix
Daymsa has carried out trials with Raiza® Mix on two potato varieties: Hermes, a Dutch potato, edible, semi-early and useful for the production of French fries, and Tajfun, a medium-early variety that produces large, almost perfectly oval tubers with a slightly yellow skin.
The treatment was carried out a few hours before planting by soaking the potato seeds for 5 minutes in a 0.66% solution, i.e. 0.2 l of Raiza® Mix was dissolved in 30 l of water. The trial was carried out in a light acid soil in a year characterised by an excess of rainfall (134.6 mm above the average of several years) and a significantly different air temperature during the vegetative growing season.
Results
After the application of the 0.66% Raiza® Mix treatment, the Hermes variety achieved an increase in tuber yield of 4.2 t/ha, i.e. 9.9% more than the control, and for the Tajfun variety 4.9 t/ha, i.e. 10.3% more than the control, as shown in the following graphs.

On the other hand, seed potato treatment with Raiza® Mix also improved the diameter distribution of the tubers produced, which increased the proportion of tubers with a diameter of 35-50 mm for both varieties compared to the control.
Raiza® Mix also contributed to increase in the starch and dry matter content of the tubers compared to the control. The level of nitrate in the tubers was relatively low as shown in the tables below. Regarding the vitamin C content in the fruits, an increase of 20% was achieved in the Tajfun variety, compared to the control treatment.

Conclusions
The tests carried out showed that after the application of Raiza® Mix on potato seed, great benefits such as increased yield or improved tuber quality were reflected.
In this sense, the application of this product on potato seed stimulated root development and improved nutrient absorption after sowing, favouring uniform germination, vigorous and stress-resistant plants, and helping the crop to reach its maximum productive potential.

Daymsa continues its commitment with EFICAL WSP, a nutritional solution to address calcium deficiencies on crop quality and post-harvest life in strawberries.
Calcium deficiency in berries can cause crop reduction and quality loss. DAYMSA presents the new applications of EFICALWSP via irrigation for a nutritional solution that facilitates a better absorption of calcium in the plant.
EFICALWSP is a biostimulant with high assimilable calcium richness that manages to increase the quality and post-harvest durability of fruit and vegetables. To improve the life of the harvest, it is essential to increase the level of calcium in the cell wall or “bound calcium”. This can be quantified by specific analysis of calcium pectate molecules. “The main difference that EFICALWSP provides us, is achieves a significant increase in “bound calcium” or calcium in the cell wall, achieving a substantial improvement in the shelf life of our fruit and vegetables”, comments José Carlos Amor, Sales Director of Daymsa.
Application of EFICAL WSP
The trial of EFICALWSP on strawberry via irrigation has been carried out in Moguer (Huelva) on the Strawberry Rábida variety, one of the most common varieties grown in Andalusia. It was carried out by technicians from the testing company ANADIAG.
The objective was to evaluate the content of total calcium and bound calcium in the fruit to see its influence on the quality of the fruit at harvest and post-harvest. The polytunnels in the trial were 85 m long with 800 plants. A total of 9.5 plants per square metre. Four applications of 4kg of EFICAWSP via irrigation were made every 15 days starting on 1 February.
Similar results would have been expected when spreading the doses of these applications on a weekly basis, for those farms where weekly applications are preferred.
Results
Total and bound calcium content was measured in specialised laboratories on fruit samples at different dates during the trial. On the of 16 February results received their last application of EficalWSP on 1 February, in 15 days earlier. An increase in the content of bound calcium was measured in the fruit compared to the control, corresponding to an increase of 17%. This is very interesting because the applicatio
This data is very interesting because the application of Efical WSP was done 15 days before the sampling, which means that the extra calcium supply from Efical WSP has been long lasting.
The next sampling for calcium analysis was done on the 4 of March (harvest three days after having received an application of Efical WSP). It is possible to see an increase in the calcium content bound in the fruit compared to the control, corresponding to an increase of 21%. This is a very positive figure which reflects the fact that the calcium supplied with Efical WSP reaches the fruit quickly.
Conclusions
The applications of EFICALWSP via irrigation carried out in this trial on strawberry crops show that the effect after application was rapid and maintained over time, with an increase in total calcium and bound calcium content being observed. This resulted in a higher fruit consistency at harvest and a higher strawberry weight (+3 grams on average). In the post-harvest period, a slowing of weight loss of between 17% and 30% was observed, as well as an increase in healthy fruit without rotting.

DAYMSA presents the benefits of using EficalWSP in the cultivation in grapes after its study carried out in Blanca, in the province of Murcia with Flame seedless variety.
DAYMSA, European leader in the production of biostimulants with a clear commitment to offer natural solutions for the agriculture of tomorrow, reaffirms its commitment to EficalWSP, a nutritional product with a great wealth of assimilable calcium, formulated with free amino-acids and organic complexes that achieve a better absorption and translocation of calcium through the tissues of the plant.
It is also a product that can be used in Organic Agriculture according to EC Regulation 834/2007 and 889/2008, NOP and JAS regulations. Control ECOCERT SA F-32600
Benefits of EficalWSP
The formulation of EficalWSP is designed to facilitate the absorption and distribution of calcium within the plant as it is complexed with organic substances, in addition to stimulating the growth of new roots that will be points of greater calcium absorption. It increases the concentration of calcium in the fruit and green parts, improving firmness and post-harvest quality by being a source of organic calcium that is highly assimilable by the plant.
In this sense, EficalWSP also stands out for its easy handling that it can be used both via foliar and root application in a wide variety of crops with a fast and high solubility in water.
Proper fertilisation with EficalWSP improves plant tissue and reduces the risk of disease penetration. This will be reflected in a better post-harvest life.
Trials carried out on grapes
Daymsa has recently carried out several trials on grapes to study the benefits of EficalWSP.
This was carried out in Blanca, Murcia by the testing company GOES. The objective was to evaluate the increase of calcium in fruit, harvest quality and post-harvest life with EficalWSP application and another source of inorganic calcium via foliar.
The trial was carried out on the Flame seedless variety, the first application was made at the same time as the gibberellic treatment with an application volume of 800 L/ha and the second application 7 days later.
Results
The results at harvest showed increases in size and weight of +5% and +12% respectively after treatments with EficalWSP. This effect on weight and size was not seen with the inorganic calcium (calcium chloride) treatment.
The grapes with the highest calcium content at harvest were those treated with Efical WSP 3kg/ha (+25% bound Ca and +12% total Ca than the control) with significant differences. The treatment with inorganic calcium at 5L/ha resulted in a lower assimilated calcium content despite applying more grams of calcium per hectare.
Berry shatter resistance was measured with a texturometer. It increased with the EficalWSP treatments (result of the structural function of calcium bound in the cell wall).
Post-harvest, after a period of cold storage and shelf life, the percentage of rotten berries was counted. The results showed a 35% reduction in rot compared to the control after the application of Efical WSP.
Conclusion
EficalWSP is suitable for grapes as no stains were observed after foliar applications.
The foliar application of EficalWSP resulted in more assimilated calcium by the plant. Moreover, the organic molecules of the formulation stimulated the growth of the fruit leading to a larger harvest, with increases in grape size and weight of +5% and +12% respectively. Considering an average of 80-120 grapes per bunch on the Flame Seedless variety, this leads to an increase of +56 to +84 grams per bunch, which is a good result.”
Post-harvest, EficalWSP managed to reduce damage by botrytis compared to the untreated control thanks to the calcium strengthening of the cell walls, therefore preventing the pathogens to penetrate the fruits.

The new Daymsa EnerPlus® biofertilizer achieves an increase in extractability of 38% in the Arbequina variety, confirming yield and early harvest after application.
Daymsa presents EnerPlus®, its new biofertilizer that promotes the biological activity of the soil with exclusive microorganisms, Pseudomonas fluorescens GR-322, which enhance beneficial microbial life on the root surface and increase plant activity.
To verify the benefits of the use of EnerPlus® in the cultivation of olive groves, Daymsa has carried out a study with the aim of confirming the influence of applications of this product based on microorganisms on the performance of an Arbequina variety olive farm, superintensive planting (SHD).
The treatment with EnerPlus® contributed to reaching maturation earlier and increasing the level of fat on dry matter to anticipate harvesting.
Study Methodology
The study carried out by Daymsa has been carried out in the south of Portugal, in an olive grove producing farm, near Beja, on the Arbequina variety, characteristic in super-intensive crops due to its early harvest, because of the quality of its fruity oils and due to its their prices, being the first to go on the market.
The trial design was randomized blocks with four replications per thesis. The theses to be compared were plots where no microorganisms were applied versus plots where two applications were made via fertigation of EnerPlus® at a dose of 1kg / ha, the application of EnerPlus® being the only difference between both theses.
The applications were made after the fruit set (July 24, 2020) and at maturity (one month later).
Two months before harvest, weekly fruit samples were taken to determine the influence of the treatment on ripening and fruit quality (from October to November). For each sample, fruits were taken from several trees within the replica until 1 kg was collected.
Proven results
An external laboratory was in charge of analyzing the samples and determining the content of total fat (Graph 1), fat on dry matter (Graph 2) and humidity (Graph 3).
After harvesting, the percentage of oil obtained with respect to the total weight of the fruit was calculated. This parameter (extractability) was compared in both theses (Graph 4). For this, the oil was extracted at a constant temperature in farm’s own facilities
