The effects of Magnetic Fertigation and Concentration of Zinc Nano Fertilizer Solution Spraying on Physicochemical Characteristics of Physalis Plant

Investigation of physicochemical variations of physalis crop, as a species with various medicinal and nutritional properties, was performed under combined treatments of magnetism intensity (M) in four levels of zero, 0.2, 0.3 and 0.4 T and concentration of nano zinc fertilizer (N) in three levels 1, 1.5 and 2 g/l. The results showed that the effect of combined treatments on all biochemical properties (except carotenoid factor), as well as all morphological traits (with exception of fruit diameter) was significant at 1% and 5% levels. By analyzing the phytochemical factors, chlorophyll b factor was significantly improved by 5.3 times as compared to the control treatment, under treatments of 0.4 Tesla and 1.5 g/l. Also, among the morphological factors, a* factor showed the highest increment (2.7 times as compared to the control) under 1.5 g/l zinc fertilizer without magnetism intensity. In general, the balanced use of these treatments could be applied in economical production of this crop.
