| description | Plant nutrition presents one of the main concerns of table growers in Morocco. Since the increase of the prices of fertilizers, the optimization of the amount of nutrients elements is important. Crop deficiency in terms of Nitrogen (N), Phosphorus (P) and Potassium (K) was demonstrated to decrease growth and productivity of plants. The objective of this research was to investigate the effect of adding Basal N-P-K Fertilizer (15-15-15) to soil on some physiological parameters of table grapes, such as chlorophyll fluorescence, plant growth and fruit yield. Trials were conducted northeast of Morocco and under Mediterranean climate conditions on a production of 8-year-old table grapes (v. Regal). The planting density was 2000 plants/ha. In a field of 10 ha of commercial production, a plot of twenty-four trees were selected for each treatment (control (C) and treated (Tr) plants with basal fertilizer). A basal fertilizer (15-15-15) was applied in the beginning of the vegetative growth stage, at 5 cm above to the root system. An amount of 150 g/tree was applied. A conventional fertilization program was used by the grower in both control and treated plots, except for the prototype treatment plots where the basal fertilizer was only applied. No significant effect of the treatment on plant growth and fruit yield was noted. Moreover, no significant difference was recorded on leaves relative water content (RWC), chlorophyll content (LCC), and chlorophyll fluorescence parameters such as: F0, Fm, Fv/Fm, Vi Vj, ABS/RC, DI0/RC, TR0/RC, ET0/RC and RE0/RC. |
