Rotaru, V. | Gojinetchi, O.
The influence of phosphorus and nickel nutrition on leaf area and chlorophyll content in soybean leaves has been investigated in relation to water deficit. Soybean plants were grown in dishes with a capacity of 5L. Mineral nitrogen and phosphorus were administated in the soil. In the bud-formation stage foliar nutrition with nickel sulfate was carried out. Untill the beginning of flowering stage the plants were maintained at a normal humidity of 70% SWC, than they were divided into two sets: the first set was maintained under normal humidity and the second was subjected to moisture stress (35%) during 10 days. Additional phosphorus nutrition increased in large measure leaf area. Water stressed plants had relatively lower leaf area and weight. Plant fertilization with moderate dose of phosphorus and foliar nutrition with nickel increased pigment accumulation in moisture stress conditions. Closer elucidation of the relation between mineral nutition and soil moisture, on the one hand, and the photosynthesis, on the other hand, will provide important scientific information for optimum growth regulation and for obtention of quantitatively and qualitatively sustainable yields.
