Effect of different organic sources of nitrogen on quality parameters and economics of amaranth (Amaranthus spp.) Cv. Arka suguna

The present investigation entitled, “Effect of different organic sources of nitrogen on growth, yield and quality of amaranth (Amaranthus spp.) cv. Arka Suguna” was carried out during late kharif 2016 at the farm of College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan (Gujarat). Experiment was laid out in randomised block design with nine treatments viz., Control (T1), 100% Nitrogen through FYM (T2), 100% Nitrogen through Vermicompost (T3), 100% Nitrogen through Castor Cake (T4),100% Nitrogen through Poultry manure (T5), 100% Nitrogen through Neem cake (T6), 20% N from FYM + 20% N from Vermicompost + 20% N from Castor Cake + 20% N from Poultry manure + 20% N from Neem cake (T7), 25% N from Poultry manure + 25% N from Neem cake + 25% N from FYM + 25% N from Vermicompost (T8) and 20% N from Castor Cake + 20% N from Vermicompost + 30% N from Poultry manure + 30% N from FYM (T9). The results revealed that the maximum chlorophyll (15.04) through SPAD meter reading, carotenoids (2.80mg/g) and protein (3.33%) was recorded with treatment 20% N from Castor Cake + 20% N from Vermicompost + 30% N from Poultry manure + 30% N from FYM (T9) and maximum iron (3.27mg/100g) was recorded with treatment25% N from Poultry manure + 25% N from Neem cake + 25% N from FYM + 25% N from Vermicompost (T8)
