RESEARCH ON WATER CONSUMPTION FOR ONION GROWING IN PRE-MOUNTAINOUS REGION OF THE APUSENI MOUNTAINS

Water consumption in onion growing was determined for different types of irrigation: 50% of AHC (Active Humidity Coefficient), 70% of AHC and no irrigation just organic fertilization or organic and mineral fertilization. Research was carried out in 2008 and 2009 using the direct method of determining the amount of water in the soil (the water balance)

RESEARCH REGARDING THE WATER CONSUMPTION OF TOMATOES, GREEN PEPPER AND CUCUMBERS CULTIVATED IN SOLARIUMS

In such conditions, saving water represents a very important aspect, both economically and socially. But in horticulture saving water must consider another very important aspect, that of providing food for a continuously growing population. So horticultors have the difficult task of obtaining big productions as well as saving water. Our research come to support the cultivators who grow tomatoes, green peppers and cucumbers in solariums. Determining precisely the water consumption of this species will create the possibility of avoiding both the excess and the lack of water of the tomatoes, green peppers and cucumbers grown in solariums, each of them having negative effects on production. Establishing the best water regime of this crop will lead to the application of optimum water quantities, at the right time and by the most efficient irrigation methods. This way, the cultivators will have the possibility of obtaining high productions, of superior quality, justified economically

RESEARCHES REGARDING FIGHTING AGAINST EROSION ON NEW FOUNDED CULTIVATED GRASS LANDS IN THE NORTH WEST OF ROMANIA

One of the first order problems which interest through its importance the whole billowy surface of the country is the preventing and fighting against soil erosion. Although there were made antierozional works on significant surfaces, their rhythm is inferior the development rhythm of the soil erosion and even these works didn’t always reach their aim. The experiments made revealed the decidedly part of the vegetal cover in fighting against soil erosion , part amplified also by the high productions of fodder gained in the case of using the biological material on different slope lands. The antierozional measures with biological character must have at their origin a study and detailed researches of the vegetation, for establishing the species and the herb mixtures corresponding to the conditions from the respective region

RESULTS OF TWO DECADES OF RESEARCH WORK ON STABILISATION AND AGRICULTURAL REVALUATION OF AN APPROPRIATED LANDSLIDE

Starting with 1976, a totally unproductive piece of land located in the Chinteni Valley, Cluj County, severely degraded by landslides, was used as an experimental field in order to study the actual possibilities of agricultural reinstatement of these lands. Out of a large range of problems studied since then, the present paper shows the most important experimental results concerning the gradual stabilisation and agricultural revaluation of landslides by means of hydro- and agroappropriative works applied. The presented results emphasise the fact that as a consequence of appropriation works applied to this landslide (drainage and levellment) as well as by using crop technologies specific for slopes, the horizontal and vertical displacements of ground have been significantly reduced. Gradually, there has been noted an obvious tendency of a long term land stabilisation followed by a natural incorporation of this land into the equilibrium condition of the slope to which it belongs
