RESEARCH ON THE INFLUENCE AGRO ON INDICATORS QUALITY PHYSIOLOGICAL RADISH (RAPHANUS SATIVUS) ON A CHERNOZEM VERTIC PUBLISHED

Carmen BEINȘAN, Casiana MIHUȚ
The research was performed on a vertic chernozem from Giarmata, Timis County. Microclimate peculiarities of the territory are determined by its geographical position, so that it is characterized by a temperate continental climate with mild winters and short, often being under the influence of cyclones and air masses crossing the Mediterranean and Adriatic general features of climate marked by diversity and irregularity of atmospheric processes. Radishes prefer soils with medium texture, loose, with a high content of humus and nutrients in forms easily assimilated with a pH of 6.2 to 7.4 and with good water holding capacity. Clay soils, compact, not suitable for the roots deforms and light soil, sand, sponges favors root tissues due to poor water regime. In terms of crop fertilization radishes, organic fertilizer is given prior culture (HORGOS A., 2002). The main quality indicators were studied concern: plant height in cm; leaf area in cm2; The total amount of chlorophyll, SPAD units; radishes firmness in LVR; soluble carbohydrate content in BRIX; the acidity of the juice obtained from radish (pH) and the amount of dry substance in%. Setting duration phenophases was made using the coding system identification BBCH stages of plant development. The measurements were carried out in three stages of growth: 4.1 - 4.3 (10 to 30% by weight of made green), 7.1-7.3 (10 - 30% of the size of the radish made) and 8.9 (full ripening and the end of the growing season).
