Abstract

This study included the effects of two planting methods (plastic house and open field) or (covered and uncovered) conditions, three levels of nano NPK fertilizer (approximately 0, 3, 6 g.l-1) and three levels of non-nano NPK fertilizer(0, 3, 6 g.l-1) were included in this trial (2x3x3=18) with three replicate experimental units (54). Nano and non-nano NPK fertilizers sprayed plants after a week from transplanting and other spraying are donetwo times with an interval of 15 days between each spray. The results showed that the covered method was superior in terms of characteristics such as plant height to(64.54cm), leaf area (647.91cm2), head weight (682.22 g), total yield (40.02 t.ha-1 compared with uncovered method . whereas, theuncovered method showed better results for number of leaves to (22.22leaf plant-1) and vitamin C (36.15) . In particular, nano-fertilizer at a concentration of 6 g.l-1 significantly increased most of parameters number of leaves to (20.61leaf plant-1), leaf area (612.66 cm), head weight (698.89 g), total yield (41.00 t.ha-1, head diameter (32.94 cm) vitamin C (35.83) phenol content (0.83 %) fiber content (2.51%) nitrogen, phosphorus and potassium (1.994-0.861- and 1.317%) compared with control. However, significant impact of non-Nano NPK on the parameters and only the traits higher plant (62.90 cm), head diameter (35.89 cm) vitamin C (35.89) fiber content (2.13%)andnitrogen content (1.972%) compared to the control.
