A study was carried out with objectives of determining the effect of various levels of FYM and inorganic nitrogen on vegetative growth, yield and quality (total carotenoids, vitamin C and nitrate concentration) of kale in temperate region of Kashmir valley during 2010 and 2011.The experimental layout was a randomized complete block design with three replications. The treatments were four levels of FYM (0, 15, 30 and 45 t ha-1) and four levels of inorganic nitrogen (0, 45, 90 and 135 kg ha-1). The addition of various rates of FYM and inorganic nitrogen that were tested significantly improved vegetative growth and increased leaf yield of kale. The yield obtained from plant grown with inorganic nitrogen was generally higher than from those with FYM. The incorporation of either FYM or inorganic nitrogen increased total carotenoids during both the years. The Farm Yard Manure at high levels (45 t ha-1) increased vitamin C while as application of Inorganic Nitrogen at 0 to 135 kg ha-1decreased vitamin C content during both the years. Results revealed that Farm Yard Manure application produced quality vegetables in terms of low nitrate concentration as compared to inorganic nitrogen. REFERENCES Ahmed S, Beigh S,H. 2009.
