Effect of Different Organic and Inorganic Fertilizers on Growth, Yield and Quality of Amaranthus under Polyhouse Condition (Amaranthus cruentus) cv. NSC 999IUS

The present investigation was carried out in the polyhouse of Horticultural Research Field, Department of Horticulture, Naini Agriculture Institute, Sam Higginbottom University of Agricultural Technology and Sciences, Prayagraj during year 2021on Amaranthus. The experiment was carried out in a Randomized Block Design consisting of 12 treatments with three replications using farm yard manure, vermicompost, poultry manure and goat manure for organic fertilizers and NPK for inorganic fertilizers to find out the best treatment combination. The application of treatment T9 [R.D.F50%+25% Poultry manure+25% Goat manure] was shown highest in terms growth attributes Plant height (37.02), Number of branches (29), plant spread (25.89), Root length (7.83), Yield per plant (151.27g), Yield per plot (5.56 kg), Yield per 200m2 (1112kg) and Anthocyanin content per 100g (158.8mg). T₉ [R.D.F 50%+50% Poultry manure] has given best results in terms of leaf length (7.36) and, Number of leaves (35.33). Therefore this treatment is best compared to other treatments and control.
