EFFECT OF ORGANIHUM PLUS ON OLIVE GROWTH  

INTRODUCTION:

Olive grove in Andalucía is of 1.400.000 ha, the 59% of surface for this crop in Spain, mainly located in Córdoba and Jaén, and the 30% in the European Union. In many regions, the olive grove is not only a crop, it is the landscape and the means in which is developed the life of its inhabitants. From this, it is obvious that its importance is not only economical or social, it is also environmental. 

METHODS AND MATERIAL

The trial was carried out in the Chemical Agricultural and Soil Science Department in the University of Córdoba, in the Altazar nursery, located in Villarrubia (Córdoba), on olive seedlings in good sanitary conditions. 

This trial is composed of two commercial varieties of seedlings (Picual and White Olive leaf.).

The treatments were made in appropriate weather conditions, with a constant manual pressure through a piston, with a temporal spacing of 40 days.

It was used an experimental design of divided lands. The two varieties were considered as main lands. In each land were made samples which consisted on three doses and an untreated control/witness. The sampling unit in each sub-land corresponded to a seedling for each one of them, with ten repetitions.

Between the foliar treatments applied, were following:  - Witness: water 

It was carried out the sprout growth length measurement, taking as starting point a signal marked on itself, immediately before the beginning of treatments. These measurements were realised in periods of 15 days during the months of June and July of 2001.

RESULTS AND DISCUSSIONS 

As one may see in the following picture, the foliar application of Organihum Plus caused a powerful growth of sprout that in the first threes measurements, that is to say, in the phase of active growth, was twice of the registered growth in the untreated witness. 

It seems clear that Organihum Plus has a stimulating effect on metabolism of plant, optimising the growth and the use of all resources presented in the substrate obtaining the best outcome. This action could be due to the improvement of nutrients absorption, to its higher assimilation and translocation inside the plant, to the points in active growth, or else to a combination of these factors. 

The highest sprout growth brought about a higher number of internodes and therefore, a higher number of leaves, with the resulting increase of the surface with photosynthetic capacity.
