Effect of Nano and non-Nano NPK Fertilizers on growth, Yield and Quality of Broccoli (Brassica oleracea var. Italica) Grown under Covered and Un Covered Conditions.

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.
