Physiological Performance of Rice Plants as Affected by Different Levels of Copper and Nitrogen Fertilizers
Year: 2004
Type: article
Abstract: This investigation was carried out during 1998 and 1999 to identify the suitable levels of copper and nitrogen fertilizers for raising the productivity of rice through the enhancement of different physiological criteria. The most important findings revealed that: Foliar application of Cu had highly significant effect on plant height. number of tillers, leaf dry weight. aboveground dry weight. leaf area index (LAI). leaf area ratio (LAR). crop gro'Nth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR). The highest mean values Vlere recorded when plants were sprayed with copper sulphate at the lellel of 11.5 kglfed. However. increasing level of sprayed Cu resulted in significant reduction in all studied traits al different gro'Nth stages. Soil application of nitrogen had significant posilive effects on all studied growth characteristics. The higher the nilrogen level the higher the mean values recorded for plant height, number of tillers, leaf dry weight. aboveground dry weight, LAI. CGR. RGR and NAR at all growth periods.
