THE INFLUENCE FERTILIZATION ON THE QUALITY PRODUCTION OF RYE IN THE CONDITIONS OF SANDY SOILS FROM SOUTHERN OLTENIA

Abstract

Cultivation of rye has a special importance for agriculture in România, this culture is the second panification cereal to after wheat. Rye is important in the culture first for fact that maybe capitalize on less favorable the soils cultivation of wheat, such as ones sand, ones acid or positioned in climate cool and moist. Regarding the uses rye, they are multiple from bakers to animal feed.
Quality characteristics values are strongly influenced by the applied technology. Productivity and production quality are influenced by dose and epoch of application of fertilizers during the experimentation. On sandy soils from southern Oltenia the culture of rye gives good results if are applied all links of the technological.
The best production results were obtained in variant fertilized with N150P80K80, in which nitrogen was applied 1/3 at sowing + 2/3 in vegetation (3336 kg / ha). Fertilization influenced the rate of protein, gluten, sedimentation index and mass of 1000 grains. Protein quantity of rye grains was comprised between from 10% the control variant and 12.2% in variant fertilized with N150P80K80 (N-100%, in the vegetation). Protein quantity calculated per hectare increase with growth grains production and between the two variables have established a correlation represented by a simple linear regression.
Increasing doses of nitrogen influences quality of the grains of rye and the best results were obtained at fertilization with N150.
Also, the epoch of application of fertilizers influences production quality and the best results were obtained when nitrogen dose was administered 1/3 at sowing + 2/3 in the vegetation or 100% in the vegetation, variants in which and production presented yield increases statistically assured.
